Answer:
Hello. You did not show the images, but the function of the connective tissue in the body is to provide support by filling the empty spaces between one tissue and another. In addition, it is responsible for nourishing the tissues to which it is connected.
Explanation:
Generally speaking, connective tissue is a connecting tissue. its function depends a lot on the cells that make it up, but in general, we can say that this type of tissue is responsible for promoting the support of other tissues in the body. This is because the connective tissue is able to fill empty spaces between the fabrics, in addition to being able to provide necessary nutrition to these fabrics whenever necessary.

What are digestive enzymes? Give three examples of digestive enzymes and briefly describe their specific functions.
Answer:
Digestive enzymes are the natural substances our body needs to help break down and digest food
We have three main digestive enzymes :
Proteases: These enzymes break down protein into small peptides and amino acids.
Lipases: break down fat into three fatty acids plus a glycerol molecule.
Amylases: Are responsible for breaking down carbs like starch into simple sugars.
Explanation:
Digestive enzymes are proteins that catalyze mainly hydrolysis reactions that make nutrients absorbable in the digestive tract. Pepsin is a gastric enzyme that turns proteins into albumoses and peptones which are shorter peptide chains that are then hydrolyzed to even shorter chains until amino acids by intestinal enzymes. Pancreatic amylase is an enzyme that turns starch(a polysaccharide) into maltose(a disaccharide). Lipase is present in the gastric juice, the pancreatic juice, and the intestinal juice. This enzyme catalyzes the hydrolysis of lipids(mainly triglycerides) into fatty acids and glycerol. When incomplete hydrolysis occurs triglycerides can become monoglycerides.

The diagram shows part of the carbon cycle. (sorry I cant add it but it includes carbon dioxide in the atmosphere, green plants, animals and microorganisms)
Describe how living things are involved in the constant cycling of carbon.
Answer:Most living things breathe out carbon dioxide(Co2)
Explanation:
Most living organisms need oxygen to survive(Animals and microorganisms).They therefore breathe in oxygen and breathe out carbon dioxide save for green plants which give out oxygen and take in carbon dioxide.
Animals and plants exchange oxygen for carbon dioxide and vice verca
Hereby involving living things in the constant cycling of carbon dioxide in the atmosphere.
An ecologist hypothesizes that predation by a particular owl species is the major factor controlling the population of a particular rabbit species. The first step in testing this hypothesis would be to determine
Answer:
The correct answer is - whether owl eats the rabbits.
Explanation:
A hypothesis is a proposed answer for an unexplained event that doesn't fit into the current acknowledged logical hypothesis. The essential thought of a hypothesis is that there is no pre-decided result.
The Hypothesis can be proved or disproved by scientific research that has various steps but initiailly testing the hypothesis is essential:
- Making assumptions.
- Stating the research and null hypotheses
- Selecting the sampling pattern and specifying the test statistic.
- calculating the test statistic.
-Making a decision and interpreting the results.
Thus, the first step after forming a hypothesis is to check or test the hypothesis which is null hypothesis -whether owl eats the rabbits.
A fine-grained igneous rock forms
Choice B is the right option since the cooling is fast.
The minerals may not have enough room to develop owing to a sudden cooling and therefore their structure is delicate and glassy. The composition of an igneous rock depends on how quickly the magma is cooled when the volcanic eruptions occur. Slow cooling allows big crystals to grow while rapid cooling allows tiny crystals to appear.

Drag each tile to the correct box. Arrange the steps in the correct order to describe how a reflex occurs. A receptor detects a signal. A sensory neuron sends a signal to the spinal cord. A bone moves. A relay neuron sends a signal to a motor neuron. A muscle receives a signal to contract. ↓ ↓ ↓ ↓
The reflex arc is the sequence of events since a stimulus reaches the body, until the body reacts to it. The correct order is a, b, d, e, c.
What is the reflex arc?The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts to it.
In general terms,
A stimulus of varying nature reaches the body. The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-. The CNS processes the information and sends another signal as a response to the stimulus.This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
Ascending branch1) The stimulus reaches the body and is received by the specialized sensory receptors.
2) Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy.
3) Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
Descending branch4) Once the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response.
5) Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
6) Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
7) Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.
In the exposed example, the corrcet order is
a- A receptor detects a signal.
b- A sensory neuron sends a signal to the spinal cord.
d- A relay neuron sends a signal to a motor neuron.
e- A muscle receives a signal to contract.
c- A bone moves.

The function of Mitosis is to produce daughter cells that _______. have the same number of chromosomes as the parent cell but not the same genetic make-up are genetically identical to the parent cell have a random assortment of maternal and paternal chromosomes
Answer:
The function of Mitosis is to produce daughter cells that are genetically identical to the parent cells. have the same number of chromosomes as the parent cell but not the same genetic make-up are genetically identical to the parent cell have a random assortment of maternal and paternal chromosomes
(The answer is underlined above)
Explanation:
Mitosis is a nuclear division. This division results in the generation of two daughter cells that are genetically identical to the parent cells and each daughter cell contains the same number of chromosomes and all cell content inherited from the parent cell. Mitosis is involved in cell development of new cells and old one, growth of both new cells and old ones, and asexual reproduction.
The chromosomes which are the DNA molecule that makes up the fundamental genome of the cell are copied before mitosis. This made sense to explain how important it is for chromosomes of the cell to be copied first before mitosis so as to enable the separation of the chromosome copies to give each cell a full set of identity similar to the one copied from.
The function of mitosis is to produce daughter cells, which are genetically identical to the parent cell.
What is mitosis?It is the process in which two daughter cells are produced, which are identical genetically to each other, and to the parent cell. The process initiates with a diploid cell with 2N chromosomes and 2X DNA content, and at the end of the process two identical cells get produced each having same number of chromosomes and DNA content.
The replication of all the eukaryotic cells takes place by the process of mitosis, apart from germline cells, which replicate via the process of meiosis. The different phases of mitosis are:
ProphaseMetaphaseAnaphaseTelophaseCytokinesisThus, the correct statement is that the daughter cells are genetically identical to the parent cell.

differentiate Sympathetic and parasympathetic nervous system
Answer:
Sympathetic nervous system makes the body ready to fight or fight response during any danger in the body.
While
Parasympathetic nervous system slow the body from performing too much work there by restoring the body to calm and composed state
Explanation:
The autonomic nervous system is divided into two; the sympathetic and parasympathetic nervous system. The autonomic nervous system controls the involuntary actions of internal organs and glands.
The sympathetic nervous system originate from the spinal cord and and it's is responsible for accelerateing the heart rate, constricting blood vessels, and raising blood pressure. Thereby preparing the body to fight or fight response against any danger.
The parasympathetic nervous is a part of autonomic nervous system that also originate from the spinal cord which which slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. By doing this,it prevent the body from overworking itself and restore the body to a calm and composed state.
what are chloroplasts? why are they green? how is the green colour plant of a great importance to the whole living world? explain?
Answer:
Chloroplasts are structures found in the cytoplasm of plant cells that are the site for photosynthesis. They are green because they contain a pigment called chlorophyll. Chlorophyll absorbs light to bring about the photosynthesis reaction. Light energy is crucial to initiate photosynthesis.
Photosynthesis allows the plant to convert carbon dioxide from air and water absorbed from the roots into oxygen and glucose, which are foods for plants. By releasing oxygen to air through photosynthesis, other living things can breathe in oxygen so that energy can be generated through another process, called respiration. Respiration is like the reverse reaction of photosynthesis, but it turns glucose to energy that supports living things.
Because plants also respire to generate energy, by using the glucose produced from photosynthesis, it also supports the food chain in the living world. Other organisms can consume plants for their energy.
In the end, chloroplasts and the chlorophyll inside are very important to the living world.
The Center for Disease Control and Prevention recommended that men infected with Zika virus delay planned pregnancies. What is the recommended length of time for delayed conception for men afflicted with Zika virus?
Answer:
This should be 6 months
Explanation:
Generally ZiKa disease is caused by Zika virus,It is transmitted by Aedes mosquito as vector.It symptoms(rashes,fever,joint pains) are mild in the first week,but very severe in pregnant women.Men who visited then endemic region are advised to delay intercourse for 3 months,while those who were infected were recommended to abstain from sex for 6 months,
This is because the virus has been found in the semen longer than other body fluids.it has been found in infected semen for 180 days after healing.
In infected pregnant women,this can be transmitted to the fetus,causing microcephaly in the unborn child,Protection against mosquito bites is best way of prevention.

Mules are considered to have many superior characteristics compared to the horse or burro. Mules are often stronger, agile, and can jump higher than either of their parents. Why are mules considered to be a weak hybrid and not a separate species?
Answer:
Because they are sterile
Explanation:
Mules are considered to be a weak hybrid and not a separate species because they are sterile and cannot produce progeny of their own.
Mules are hybrid products from two separate species - a donkey and a horse.
A species is generally defined as a group of organisms that are capable of breeding to produce fertile offspring. Hence, in order for them to have the potential of being categorized as a separate species, they must be able to produce their own progeny but this is not the case.

If a cell has 32 pairs of chromosomes in its diploid state, how many chromosomes will it have after Meiosis 1? A. 8 B. 64 C. 32 D. 16
Answer:
option c is correct that is 32
Explanation:
meiosis occur in two phases in the first phase DNA replication occur and amount of DNA becomes doubled without any changes in the chromosomes number and two daughter cells( each 2n) are formed
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells each with half chromosomes (n)
now 2n =32
n=32/2=16
after meiosis stage 1 ........ two daughter cell each with 32 chromosomes
stage 2.... each daughter cell form two grand daughter cell each with 16 chromosomes
A cell with 32 pairs of chromosomes will have 32 chromosomes after meiosis I
WHAT IS MEIOSIS?
Meiosis is a cell division that results in the formation of four daughter cells that have their chromosomal number reduced by half i.e. from diploid (2n) to haploid (n). Meiosis occurs in a two step division process namely: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes while meiosis II involves the separation of sister chromatids.The actual reduction in chromosome number takes place in meiosis I. Hence, a cell with 32 pairs of chromosomes i.e. 64 chromosomes will have (64 ÷ 2) = 32 chromosomes after meiosis I.
