A student is given four components of evolution, shown in the four boxes here. Which statements can be formed using the terminology shown here to accurately describe the evolution within a species? Select ALL that apply.
Answer:
C and E
Explanation:
The key feature here is that individuals cannot evolve. Individuals are either adapted in their movement. This is how evolution by means of natural selection occurs.
The statements which can be formed using the given terminology are: Individuals have different genetics, leading to the evolution of populations. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution. Thus, the correct options are C and E.
What is Evolution?Evolution can be referred to as the change in heritable characteristics of biological populations over the period of successive generations. These characteristics are the expressions of genes, which are passed on from the parents to their offspring during the process of reproduction.
The statements which can be formed using the given terminology include: 1. Individuals have different genetics, leading to the evolution of populations. 2. Individuals with adaptations are based on genetics, allowing for populations to undergo evolution
Therefore, the correct options are C and E.

the countries with the highest fertility rates are also the ones with the highest infant mortality rates. which one causes which and how do we know?
Answer: Higher infant mortality rates cause higher fertility rates.
Explanation:
Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.
If I had a section of DNA that contains 350 nucleotides and the A's and Ts made up 200 of
those nucleotides, how many As
Gs
Cs
and Ts
do I have?(.5 points each response)
Answer:
100 A
100 T
75 C
75 G
Explanation:
there will be an equal amount of thymine and adenine since they bind together so, 200/2 = 100 each
now there is 150 nucleotides left
guanine binds to cytosine so they also have an equal amount, so 150/2=75
Answer:
As = 100
Ts = 100
Gs = 75
Cs = 75

Although we consume different foods, the parts are eventually used in cellular respiration. Does it matter if they originate from crickets or cows or candy bars?
Given what we know about biological processes, we can confirm that it does not in fact matter where the nutrients come from in terms of cellular respiration.
We consume food to provide the energy we need to function on a daily basis, for this, we may reach for an apple or opt for a candy bar. However, this is irrelevant on a cellular level. Cells do not eat the food the way that we consume them.
They use a process known as cellular respiration to change the food into energy to be used by cells. The most important of this process is the transformation of high-level sugars into simple sugars like glucose and other monosaccharides.

What is the major consideration in setting the lower limit of cell size?
A. The cell size must be small as to fit all the processes and structures to support life.
B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.
Answer:
c
Explanation:
The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.
The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.
This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?
Answer:
Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins

Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.
1. How did the occurrences of the different traits change over the 30-year period? Use evidence from
the graph to support your answer. Using what you know about natural selection and adaptation, what
generalization can you make based on these changes?
Explanation:
scam fakeeee
just kidding the answer is
every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.
