how do neurons transmit signals throughout the body?
Answer:
When neurons communicate, an electric impulse triggers the realease of neurotransmitters from the axon into the synapse.

DNA is copied during the S Phase of Interphase. Why do cells copy the DNA?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
Explanation:
If the original cell
(parent cell) has 30
chromosomes, how
many chromosomes
will the new cells

Explanation:
the fossil fules are used as energy sources but they cause pollution and are what
Answer:
The correct answer is - non-renewable.
Explanation:
The non-renewable source of energy is the source of energy that can not be replaced naturally in the manner and the pace of the consumption of these sources. Nuclear, oil, fossil fuels, natural gases and other are an example of these type of energy source.
Fossil fuels were generated due to the decomposition of the dead plants and animals within the Earth over millions of years therefore these are called fossil fuels. These fuels are cause pollution by burning.
*lf a strand has 35% adenine, what percent will be cytosine?
Answer:15% cytosine
Explanation:We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.
What do the NADPH and ATP do in the Calvin cycle?
Answer:
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar.

Multiple choice answers
-Sugar-Nitrogen Base
-Sugar-Phosphate
-Phosphate-Nitrogen Base
-All sugar molecules
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

what are density dependent limiting factors? provide examples and describe how they affect a population.
Answer:
china world was large puplation of ther country and dencity was multiple
Answer:
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

what is the difference between an organism and a population in an ecosystem?
Answer:
Explanation:
An organism refers to a single individual living in an ecosystem and population refers to a group of organisms living together in the same area.
Answer: A population in an ecosystem is the amount of species living in that ecosystem, while an organism is a single living entity.

Which statement correctly describes a difference between asexual and sexual reproduction?
Answer:
B) Asexual reproduction involves one parent, and sexual reproduction involves two parents.
Explanation:
In asexual reproduction, offspring formed from only one parent whereas, in sexual reproduction, offspring produces from two parents. The offspring is identical to the parent in asexual reproduction while on the other hand, offspring is different from their parents. Sexual reproduction increases the chances of survival of the species due to genetic diversity whereas asexual reproduction has limited chances of survival due to lack of genetic diversity.
Asexual reproduction involves the production of offspring without the involvement of gametes, resulting in genetically identical offspring. On the other hand, sexual reproduction involves the fusion of gametes from two parents, resulting in offspring with genetic variation.
Asexual reproduction and sexual reproduction are two different methods of producing offspring in living organisms. Here are the differences between them:
1. Asexual reproduction:
Asexual reproduction involves the production of offspring from a single parent without the involvement of gametes (sex cells). This means that the offspring are genetically identical or clones of the parent.
Examples of asexual reproduction include binary fission in bacteria, budding in yeast, and regeneration in starfish. In binary fission, a single-celled organism divides into two identical cells. In budding, a small bud grows on the parent organism and eventually detaches to become a new individual. In regeneration, an organism can regrow a lost body part and develop into a complete organism.
2. Sexual reproduction:
Sexual reproduction involves the fusion of gametes from two parents to produce offspring. Gametes are specialized sex cells, such as sperm and eggs, which contain half of the genetic material of the parent.
In sexual reproduction, the offspring inherit genetic information from both parents, leading to genetic variation. This genetic diversity is important for the survival and adaptation of species over time.
Examples of sexual reproduction include humans, animals, and many plants. In humans, sperm from the male parent fertilizes an egg from the female parent, resulting in the formation of a zygote. The zygote then undergoes development to form a new individual with a unique combination of genetic traits.

why do birds have short necks? pls help :/
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
