Answer:
osmosis is responsible for the ability of plants roots to draw water from the soil.
Explanation: osmosis is simpliy the ability of a water to pass thourgh a semipermiable membrane from a region of low concentration to a regin of high concentration, so plants concentrates solutes in their root cells by active transport and water enters the roots though osmosis. Osmosis is also responsible for movement of gurd cells.

Which three components are common to the circulatory systems of most living animals?
arteries, veins, capillaries
vessels, heart, circulating fluid
aorta, ventricles, atria
blood, heart, cavities
Answer:
B. VESSELS, HEART, CIRCULATING FLUID.
Explanation:
Blood is the circulating fluid. It is the connective tissue of liquid plasma and cells.
Heart is a muscular pump to move the blood and have it circulate throughout the body of living animals.
Blood vessels are arteries, capillaries and veins that deliver blood to all tissues.
The Circulatory System has two types. They are the open circulatory system and the close circulatory system.
An open circulatory system is one where the blood does not circulate inside blood vessels but also flows into cavities that irrigate tissues.
A close circulatory system is one where the blood circulate only inside the blood vessels.

Q6. A neurotransmitter would have a greater chance of starting an action potential in a post-synaptic neuron by:
opening K+ channels in the post-synaptic membrane
causing a graded depolarization in the post-synaptic membrane
causing a graded hyperpolarization in the post-synaptic membrane
closing Na+ channels in the post-synaptic membrane
Answer:
a
Explanation:
Neurons secrete chemical molecules that act as messenger and takes part in signalling at the arrival of any chemical or electrical impulse are called a neurotransmitter.
The action potential can be started by:
Option a. Opening K⁺ channels in the postsynaptic membrane.
The action can be explained as:
The presynaptic neurons are the active neurons that transmit the impulse from the synapse with the help of neurotransmitters.The resting neurons or the postsynaptic neurons upon receiving the impulse open the channel gates.The postsynaptic receptors interact with the neurotransmitter that leads to the opening or closing of the ionic channels on the membrane.This leads to depolarization of the membrane causing action potential to occur.Thus potassium channels open.

What is it called when plants lose water through their leaves?
A. Transpiration
B. Percolation
C. Precipitation
D. Condensation
Answer:
A. Transpiration
Explanation:
Transpiration occurs through the stomata of the leaves.
Hope it helps.
Transpiration is the term used when plants lose water through their leaves. transpiration is an important process for plants and for the Earth's water cycle, helping to regulate water balance, transport nutrients, and regulate temperature. Hence option A is correct.
What is transpiration?Transpiration is the process by which plants lose water from their leaves through tiny pores called stomata. Stomata are located on the underside of the leaves, and they allow water vapor to escape from the plant into the surrounding atmosphere. Transpiration is a vital process for plants as it helps to regulate their internal water balance and temperature.
During transpiration, water is drawn up from the soil through the plant's roots and into the leaves. Water is then released through the stomata as water vapor, which evaporates into the air. This process is driven by the plant's need to transport nutrients and minerals from the soil up to the leaves, and to regulate its internal temperature.
Transpiration also plays an important role in the global water cycle, as it contributes to the amount of water vapor in the atmosphere. This water vapor can then condense to form clouds, which can lead to precipitation in the form of rain or snow.
Hence option A is correct.

In this assignment, you will conduct research to construct an explanation of how macromolecules are used in the body. You will then revise your explanation based on new information from additional research.
Answer:
Macro-molecules are used in the body after the conversion of micro-molecules.
Explanation:
Macro-molecules such as protein, carbohydrates and fats etc are bigger in size which can not be absorbed by the cell of the body so these Macro-molecules first broken down into micro-molecules such as amino acids, glucose and fatty acids etc. Protein is converted into amino acids, carbohydrates is converted into glucose and fats is converted into fatty acids by the action of different enzymes. These micro-molecules are used by the cell in order to generate energy.
Answer:
Macromolecules are important for the body and therefore, are used frequently. For example, “macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.” There are four major types of macromolecules, those of which are as follows; proteins, carbohydrates, nucleic acids, and lipids. All of these play these important roles in the life of a cell. Macromolecules such as protein, carbohydrates and fats are bigger in size which can not be absorbed by the cell or the body, so these macromolecules are first broken down into micro-molecules, such as amino acids, glucose and fatty acids, etc. Protein is converted into amino acids, carbohydrates are converted into glucose, and fats are converted into fatty acids by the action of different enzymes. Proteins use amino acids which provide cell structure, send chemical signals, and speed up chemical reactions. Nucleic acids use nucleotides that store and pass on genetic information. Carbohydrates use monosaccharides (aka simple sugars) to provide cells with quick, short-term energy and a source of dietary fiber. Lipids use fatty acids and glycerol to provide cells with long-term energy, and they make up biological membranes. That is how macromolecules are used in the body.

Read the passage: Genetically Engineered Corn. Then 1. Explain what Bt corn is and how it is made. 2. Describe the benefits of Bt corn. 3. Describe the risks of Bt corn. 4. Make an argument for or against the use of Bt corn and provide support for your position.
1. Bt maize is a genetically modified maize. It is produced through biochemical techniques and with the use of biotechnology that allows genes of Bacillus thuringiensis bacteria to be introduced in the DNA of corn. These genes allow Bt maize plants to produce a toxic protein specific to certain groups of insects.
2. With the production of this protein, Bt corn becomes immune to attack by these insects. As a result, the use of pesticides in the corn crop is reduced, which makes production healthier and avoids side effects on the soil. In addition, it prevents the production of corn from falling due to the attack of insects.
3. Among the disadvantages, we can say that Bt maize does not control all the pests that attack maize, only a few, which allows maize to be attacked. It can also trigger evolution in pest species that are immune, creating a toxin-resistant species. Finally, it can create contamination in wild maize crops (that is, those that have not been genetically modified), ending diversity.
4. I believe that the use of Bt corn is favorable. This is because it allows a greater production of food to meet our need and increasingly intense demand for food. However, it is necessary to affirm that the use of this corn needs regulation and inspection, mainly in the big industries that can harm the small producer.

Those with generalized anxiety disorder are likely to have overactivation of _________________ with anxiety-provoking events:
1. Serotonin
2. The amygdala
3. The hypothalamus
4. Norepinephrine
Answer:
2
Explanation:
When an individual experiences excessive and continuous worry and anxiety about certain events of life(families,job security} to the extent that this happens uncontrollably in the subject, and difficult to control, such neurological disorder is called generalized anxiety disorder (GAD).
It is caused by over activation or stimulation of the region of the brain(amygdala) that mediate response to fight and flight stimulus and fear.
It is usually diagnosed when the inability to control worries extends beyond days to months with symptoms like poor concentrations, overthinking ,indecision, inability to relax, continuous taking every event as life threatening and disrupted sleep patterns.
Generally, sensory stimuli of fear or danger in the brain are transmitted by two brain circuits to two regions of the brain, to the peripheral cerebral cortex for processing voluntary decisions about the situation, and the Amygdala for processing involuntary emotional decision.
Physiologically; it is the amygdala that processes how the body reacts to the effects of the stimuli in the immediate environments, the influence of the stimuli on the emotions of the subject, and the involuntary response to the stimuli by the subject.
In response to the sensory stimuli of fear It stimulates the hypothalamus, which in turn activate the circulatory and breathing centre of the brain.Therefore,hormones(adrenaline) are released into the blood stream to increase blood pressure, heartbeat, breathing rate, muscle contractions and other involuntary response to anxiety. This gives a fast response compare to the cerebral cortex which takes time to relay response.
Amygdala, generally stores memories of all emotions, fear, and anxiety. In GAD patients, their Amygdala is sensitive and had been adapted to the storage of fear and anxiety to the extent that every slight normal event which does would not portend danger is over reacted to with fear or flight response which triggers the two brain circuits described above to give anxiety-provoking events.

The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
Complete question: The image shows the skulls of three different organisms. The foramen magnum position is the hole in the skull where the spinal nerve cord passes through. Based on the structure of the skulls, which two statements can you infer?
a) All three organisms share a common evolutionary lineage
b) Wolves do not share any common ancestors with humans and chimpanzees.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
d) Chimpanzees share more common ancestors with wolves than they do with humans.
Note: The skull figures are shown in the attached file
Answer:
a) All three organisms share a common evolutionary lineage
c) Humans likely share more common ancestors with chimpanzees than they do with wolves.
Explanation:
Although controversial, there is a theory that states that the foramen magnum is associated with bipedalism and human beings´ evolution. According to different studies, the foramen magnum moved from the posterior part of the skull to a central and ventral position. This displacement occurred as mammals began to move in two legs - bipedalism-.
When comparing different mammals skulls it seems evident that bipedalism and foramen magnum position and orientation are highly related. Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals.
In the exposed example, when comparing these three skulls, the two statements that might be inferred are:
a) All three organisms share a common evolutionary lineage. This is true because they are all mammals, and as a group, they share a common ancestor in evolution.
c) Humans likely share more common ancestors with chimpanzees than they do with wolves. This is true because by analyzing the foramen position, we can see that both the chimpanzee and the human´s foramen is located on the ventral side of the skull. Chimpanzees´ hole is more posteriorly and humans´ hole is more anteriorly or centrally located, but in both cases, they are in ventral position. Wolves´ hole, on the other hand, is located posteriorly. As we said before, Although all mammals have a common ancestor, the foramen magnum of bipeds mammal organisms is located more anteriorly and ventral than the foramen magnum of the quadrupeds mammals. And groups closer to human beings (in this case is chimpanzee) show their foramen magnum in a similar place than those mammal groups that are further in evolution (wolves).

Explanation:
Compare and contrast the reproductive cycles of a flowering plant and a human. Include two similarities and two differences in your answer.
Answer:
Similarities: 1) They both reproduce sexually by fertilization 2) They both have male and female reproductive parts
Differences: 1) Plants can either be monosexual or bisexual while humans are always bisexual
2) Plants employ double-fertilization while humans don't
Explanation:
All organisms including plants and humans have to reproduce in order to produce young generations. However, there are similarities and differences between the reproductive cycles of these organisms. According to the question, we'll be comparing and contrasting reproduction in flowering plants and humans.
SIMILARITIES:
Both flowering plants and humans have sexual means of reproducing, which involves fusion of male and female gametes to produce a ZYGOTE, a process called FERTILIZATION.
Also, the opposite gametes that fuses during fertilization are produced by distinct male and female parts on both flowering plants and humans. For example, the anther produces the pollen containing the male gametes, while the ovary produces the egg cells in flowering plants. The testes and ovary produce the sperm and eggs in humans.
DIFFERENCES:
Flowering plants can either be monosexual i.e. bear both male and female reproductive structures on same plant or bisexual i.e bear the different reproductive structures on different plants. Humans are always bisexual i.e. they bear different reproductive structures depending on the sexuality.
A phenomenon unique to flowering plants called Double Fertilization occurs. This is a process whereby a triploid endosperm is formed from the fusion of two haploid nuclei with a sperm cell. This process only occurs in flowering plants and is absent in human reproductive cycle.

Based on your model, do you think frogs reproduce sexually or asexually? What are the benefits and drawbacks to this
form of reproduction?
Answer:
Frogs reproducesexually and when organisisms reproduce sexually there are benefits which include:
produces genetic variation in the offspring.
the species can adapt to new environments due to variation, which gives them a survival advantage.
a disease is less likely to affect all the individuals in a population.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species , however, outweighs this disadvantage.
Answer:
Frogs reproduce sexually: they require sperm from a male and an egg from a female to produce offspring. This type of reproduction allows for greater genetic variation. But organisms that sexually reproduce need to reach sexual maturity before they can reproduce. They also use energy to find a mate.
how are the respiratory and circulatory systems connected
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli.
