Answer:
Polar regions
Explanation:
Because plants don't survive in the extreme cold and ice that cover these regions year-round.
Due to their intense and harsh environmental circumstances, polar regions like the Arctic and Antarctica often have the lowest levels of biodiversity. So, the correct option is B.
What is Biodiversity?The term "biodiversity", which is short for "biological diversity", describes the range of living things and ecosystems that exist on Earth. It includes a wide range of species, genetic diversity within those species, a wide range of environments, and a range of ecological processes. Humans benefit greatly from biodiversity as it provides them with food, medicine and ecological services such as pollination and water and air purification.
Because of their intense and harsh environmental conditions, polar regions such as the Arctic and Antarctica often have the lowest levels of biodiversity. These regions have a relatively limited diversity of species because the cold and dry conditions make it difficult for many species to live. Furthermore, these areas often have low population density due to the severe environment and scarce resources.
So, the correct option is B.

If the 46 chromosomes are duplicated during interphase, why are there
still 46 chromosomes and not 92?
Before I talk about why there are still 46 chromosomes, I'll just review the basic chromosome structure. Each chromosome has a chromatid, with one centromere in the middle.
Chromosomes aren't counted by how many chromatids there are, but rather how many centromeres. When DNA duplicates, the chromatids replicate themselves, so each chromosome ends up having two sister chromatids joined at the same centromere.
There is the same number of centromeres in the cell, so there are still technically 46 chromosomes. However, there are 92 chromatids.
This used to be confusing for me too :) hope it helps!

Answer:
Genetic drift Natural
Explanation:
In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence? Genetic drift Natural In evolution, which driving factor most consistently requires a small population as a precondition for its occurrence? Genetic drift Natural selection Nonrandom mating Mutation.
In evolution, Genetic drift is the driving factor which most consistently requires a small population as a precondition for its occurrence.
What is Genetic Drift?A change in the relative frequency of alleles within a population is an example of genetic drift. Natural selection, often known as the differential survival and reproduction of individuals across a population as a result of differences in phenotype, is one of the possible causes of this phenomenon.
Natural selection gives an advantage to some characteristics in a population, which results in certain individuals being able to reproduce while others, who have characteristics that give them a disadvantage, will provide their genes to subsequent generations. This will ensure that the allelic frequency of each successive generation will be distinct from that of the parent group.
Therefore, a subpopulation may become genetically diverse from its parent population due to genetic drift.

The fluid that is formed when blood flows through the glomerulus and some components of the plasma enter the capsular space is called tubular fluid.
What is the fluid filtered out of the blood in the glomerulus called?
Filterable blood components include water, nitrogenous waste, and nutrients in an effort to be transferred into the glomerulus to shape the glomerular filtrate. Non-filterable blood components encompass blood cells, albumins, and platelets, so as to depart the glomerulus through the efferent arteriole.
Glomerular filtration is step one in making urine. It is the process that your kidneys use to clear extra fluid and waste merchandise out of the blood into the urine amassing tubules of the kidney, so they may be eliminated from your body.

Before receiving FDA approval, the tTAV protein had to be tested for any potential toxicities to other native animals. Why would this be part of the approval process?
Given what we know, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.
Why is this testing important?FDA toxicity testing for potential toxicities native to other animal species can be an essential part of any approval process. This part of the process ensures that the compound in question is free of toxins that not have been noticed in previous tests due to the innate resistance of the animal it was tested on, to begin with. This allows for a more thorough screening process and a safer end product.
Therefore, we can confirm that toxicity testing would be necessary before receiving FDA approval in order to discard the risk of harming future recipients.

What 4 body systems are used for CLEANING
YOUR ROOM?
List each body system (4 systems should be
listed) and explain how each system helps the
body when you clean your room.
Here are the body systems we talked about in class. Use this list to help you recall the types of systems
in the body: Muscular System, Skeletal System, Nervous System, Circulatory System, Digestive System,
Immune System, Reproductive System, Integumentary System, Respiratory System, Excretory System
Answer:
The skeletal system:This system controls our bones so we aren't just a blob on the ground. Our bones help keep our important organs intact.
The muscular system works about the same way, it protects your bones so they don't grind against eachother when you move. Your muscles give you the ability to move.
Our organ system is what keeps us alive, you can't clean your room if your dead and if your room is hot you need your skin so you don't overheat and die.
Lastly of course is your respitory system, you need to bring when your moving about. Our ability to breathe gives our blood cells and our heart what they need to keep working.
