Answer:
Because a major function of the cell wall is to act as pressure vessels, preventing over-expansion of the cell when water enters. The cell wall, along with the cell membrane, functions also as a filter and gives support to the cell

The chromatin which is made up of the
DNA is found in this part of the cell,
the
cytoplasm
neurone
nucleus
cell membrane
How does the number of chromosomes
compare from original cell to new cells
produced?
Answer:
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

How does heart rate change during and after an exercise is performed for two different periods of time?
Answer:
During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.
Explanation:
During workout, the heart usually beats faster, allowing more blood to leave person's body. The heart can also boost stroke volume by pumping harder or increasing the amount of blood in the left ventricle before it pumps.
What is workout?A session of vigorous physical exercise or training at either gym, home, or any fitness center is referred to as workout.
The heart usually beats faster during exercise, allowing more blood to leave the body.
The heart can also increase by pumping the stroke volume more forcefully or increasing the amount of blood in the left ventricle prior to pumping.
Thus, heart rate change during and after an exercise is performed for two different periods of time.

Explain why temperature changes occur.
plz help
Answer:
Hello! Sorry I am late! Here is my best answer below!
Temperature depends on the tilt of earth. The closer the earth is to the sun the warmer it gets. If the sun is not pointing at the place you live in the earth the temperature where you are will be colder. If the sun is pointing at the place you are the temperature will be warm. In conclusion, the temperature just depends on the tilt of earth towards or away from the sun.
Some more information:
At night you may discover that it is much colder than during the day. This is because the sun is not pointing at that half of the earth.

C. There are ribosomes found inside mitochondria and chloroplasts just like there are Inside cells.
D. Looking inside mitochondria and chloroplasts , one will find that they each contain their own DNA .
Answer:
B, C and D
Explanation:
Mitochondria and chloroplasts are not found in prokaryotes, since they prokaryotes do not contain any membrane-bound organelles. Chloroplasts are not found in animal cells either, so A is incorrect.

Answer:
In the 1890s, Northern elephant seals were hunted almost to extinction. An unknown population of less than one hundred animals managed to survive on the tiny island of Guadalupe off of Mexico. The current population of over 100,000 is thought to be derived from that tiny remnant population. Compared to the Southern elephant seals (which did not experience such a bottleneck), the Northern elephant seals likely have Lower genetic diversity and Higher levels of genetic diseases.
Explanation:
Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect-.
In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population, the population size might have recovered to a current population size of 1000,000 individuals, but the genetic pool might have not. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and increase the probability of developing a genetic disease.

Describe why certain traits increase in frequency in a population. Provide ONE example to support your response. Be thorough in your response. (should be about 5-7 sentences)
Quick!
Answer: Certain traits increase in frequency in a population because when recombination occurs during sexual reproduction, genes are usually shuffled so that each parent gives its offspring a random assortment of its genetic variation, so the frequency of a gene may increase in a population through this genetic variation. One quote from a source I read states, "When recombination occurs during sexual reproduction, genes are usually shuffled so that each parent gives its offspring a random assortment of its genetic variation. However, genes that are close together on the same chromosome are often assorted together. Therefore, the frequency of a gene may increase in a population through genetic hitchhiking if its proximal genes confer a benefit."(lumen) This quotes explains why certain traits increase in frequency in a population.

Certain traits increase in frequency in a population because they have dominant traits.
What is dominant phenotype?What is dominance? We say that an allele is dominant when it manages to determine a phenotype, even if it occurs in a single dose. This means that the dominant allele will express itself in both homzygosity and heterozygosity. Dominant allele is expressed in the phenotype, even in a single dose.
With this information, we can conclude that certain traits increase in frequency in a population because they have dominant traits.

Dr. Flores wants to know which of the forum claims is best supported by the evidence you have gathered from your previous Sim observations and the text. Select the claim you think is best supported from the options below. Claim 1: Molecules in a substance disappear or no longer exist when a substance changes phase. O Claim 2: Molecules in a substance move differently when a substance changes phase. Claim 3: Molecules in a substance change into a new kind of molecule during a phase change.
Answer:
Claim 2: Molecules in a substance move differently when a substance changes phase.
Explanation:
Molecules in a liquid phase move freely and bump into each other. In a gas phase, the molecules move with a lot more energy and bump more times against each other; there is a lot of space for the molecules to move. In a solid phase, the molecules hardly move, there is not much space between them, and they are together, often in a regular pattern.
In conclusion, when matter changes from one phase to another, the molecules move differently.
Answer:
you will need to either add or take away energy and pay attention to how the molecules move. Molecules of a solid move in place, molecules of a liquid move around each other, and molecules of a gas move away from each other.
Explanation:
