vitamin(a) retinol function on the body
Answer: Function. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A (retinol) is ingested as either retinyl esters or carotenoids and metabolized to active compounds such as 11-cis-retinal, which is important for vision, and all-trans-retinoic acid, which is the primary mediator of biological actions of vitamin A

What happens to chromosomes when an ovum and a sperm meet at fertilisation
Answer: When egg and sperm cells combine in fertilizations, they merge the two sets of chromosomes, ending up with 46 chromosomes in total. The maternal chromosomes from the egg cell and the paternal chromosomes from the sperm cell pair up. The resultant cell is called a zygote. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

How does gene flow directly contribute to evolution?
Answer:
Evolution can also occur as a result of genes being transferred from one population to another. This gene flow occurs when there is migration. The loss or addition of people can easily change gene pool frequencies even if there are no other evolutionary mechanisms operating.

What happens if the mRNA strand is not transcribed properly?
how is the mitochondrial DNA (mtDNA) transferred from generation to generation.
Answer:
maternal mtDNA
Explanation:
While nothing but the haploid nucleus remains of the sperm during fertilisation, the ovum still has its mitochondria and other organelles. Mitochondria are capable of division and will divide according to cell's needs.
So it is the maternal mtDNa that gets passed on. Spontaneous mutations can happen at any point ofcourse and get passed on in the same way.

How do you get rid of homologous chromosomes?
Answer:
hear is the answer hope it helps
PLEASE HELP ASAP !!! The model represents mutations in two non-homologous chromosomes. The letters represent genes.what does this model represent?
a ) translocation during crossing - over
b) point deletions that occur spontaneously
c) point insertions that occur during the cell cycle
d ) missense mutations that do not affect traits
Answer:
a ) translocation during crossing - over
The model this represents is an option a. translocation during crossing-over
What is translocation?Translocation refers to when the location is changed. In other terms, it is genetic which means at the time when the chromo-some part should be shifted to the other chromo-some. Here chromo-some should be structured that carry the gene.
Since the model shows the mutations in the 2 homologous chromosomes so the model this represents is an option a
Therefore, The model this represents is an option a. translocation during crossing-over

Which of the following is not a principle of natural selection?
Answer: The last one on the bottom i'm in biology
The statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others. So, the correct option is D.
What do you mean by Natural selection?Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.
The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.
Therefore, the statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others.

The tree population and the ground population of ticks cannot mate and have offspring indicates speciation has occurred.
What is population?"A population is defined as a group of individuals of the same species living and interbreeding within a given area."What is speciation?"Speciation is the evolutionary process by which populations evolve to become distinct species."The ticks of tree and ground population evolve without interfering with one other. Forms a different species and no mating occurs between them.Hence, the correct answer is: The tree population and the ground population of ticks cannot mate and have offspring.

What is needed for a fossil to form? Select all that apply.
1. The organism must first get stuck in rock.
2. The soft tissue of the dead organism must be eaten by scavengers before the bones can be preserved.
3. The tracks or burrows of an organism must be filled with sediments before they are disturbed.
4. The organism's body must be covered by sediment or another substance before its body decays.
The correct answer is:The organism's body must be covered by sediment or another substance before its body decays.
What is the explaining statement for the same ?Explanation: For a fossil to form, the organism's body must be rapidly buried in sediment, ash, or another substance before it can decay or be eaten by scavengers.
Over time, the minerals in the surrounding sediment or substance can replace the organic material in the bones, forming a fossil. Tracks, burrows, and other trace fossils can also form when sediment or another substance fills in the impressions left by an organism before they are disturbed.
Getting stuck in rock is not necessarily a requirement for fossilization, as fossils can also form in sedimentary rock or other types of rock.
Lack of oxygen: Decay requires oxygen, so organisms are more likely to fossilize in environments where oxygen is limited or absent, such as in deep water, bogs, or quicksand.
Low acidity: Acidic environments can dissolve bones and other hard parts, so fossils are more likely to form in environments with neutral or basic pH levels.
Lack of disturbance: Fossils are more likely to be preserved if they are not disturbed after burial. For example, if an organism's body is exposed to air or water before it can be buried, the bones may be scattered or destroyed.
Overall, fossilization is a rare and complex process that requires a combination of specific conditions to occur. As a result, the fossil record provides only a partial and biased glimpse into the history of life on Earth.

1. List five organelles eukaryotes have that prokaryotes do not have.
2. Explain how the following organelles ensure that a cell has the proteins it needs: nucleus, rough ER, vesicles,
and Golgi apparatus.
3. What is the main difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
4. Describe the three types of vesicles.
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.

Answer:

Explanation:

Peter is complaining of stomach pain and constant hunger as he was diagnosed with a worm infection.
Peter feels hungry because the tapeworm is absorbing food from his intestine as tapeworm begins to feed off your body's nutrients to grow once it invades the body.How tapeworm infection occurs?Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae.When tapeworm hatches and attaches itself to your intestine, it starts feeding off body's nutrients causing increase in apatite (hunger increases).It grows by reproducing proglottids ( chain looking body part) and the cycle continues.Planaria upon causing infection feeds on blood cells hence can not cause apatite.Leech and marine worm can not invade the body like tapeworm and planaria.To learn more about tapeworm infections:
