Natural selection, adaptations, genetic variation, and population evolution are all related in terms of changes in phenotypes over
time. Evaluate which statement appropriately describes the relationship between the concepts of natural selection, adaptations,
genetic variation, and population evolution and select the best choice.
A)
8)
Genetic variation exists in a population. Some of the genetic variation
results in different phenotypes. The phenotypes that enhance survival are
called adaptations. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Adaptations exist in certain individuals in a population. The increase in
adaptations causes an increase in genetic variation. The adaptations that
enhance survival lead to larger populations, which further increases
genetic variation. Individuals with well-adapted phenotypes are more
Likely to survive and reproduce, leading to population evolution over
generations.
Genetic variation is high in a population, but random events cause it to
decrease. Populations with fewer individuals and lower genetic diversity
are able to undergo natural selection when selective pressures are high.
The increase in selective pressure causes an increase in adaptations that
are better suited for survival This results in an evolutionary change of a
population
Selective pressures exist in nature and cause changes in a population.
Populations with high selective pressures have higher rates of genetic
change, leading to an increase in genetic variation, Increased genetic

Answers
Answer:
A is the answer
Explanation:
I'm just guessing
Genetic variation exists in a population. Some of the genetic variation results in different phenotypes. The phenotypes that enhance survival are called adaptations. So, the correct option is A.
What is Genetic variation?Genetic variation among members of the same species is called genetic variation. This variation may be due to variations in gene expression, DNA sequence and epigenetic changes. Mutation, genetic recombination, and genetic drift are causes of genetic variation, which can be altered by environmental variables including exposure to chemicals or climate changes.
Genetic diversity is important because it gives natural selection a starting point to work from, helping organisms to adapt and change over time. There is genetic diversity within a population. Different phenotypes are the result of some genetic variation. Adaptations are traits that improve survival.
Therefore, the correct option is A.

A researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely
Answers
From this observation, it is possible to conclude that there are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. Prokaryotic genes do not contain introns.
Introns are internal non-coding segments of eukaryotic genes that must be removed to produce the final mature mRNA.
In prokaryotic genomes, there are no introns, and genes are expressed in groups known as operons.
Eukaryotic genomes contain highly repetitive intergenic (regulatory) and intragenic (introns) non-coding regions.

They have unique combinations of chromosomes.
What are gametes?
In organisms that reproduce sexually, a gamete is a haploid cell that unites with another haploid cell during fertilization Gametes, commonly known as sex cells, are an organism's reproductive cells.
A female is any individual that generates the bigger kind of gamete—called an ovum—and a male creates the smaller type—called a sperm—in species that produce two morphologically distinct forms of gametes, and in which each individual produces only one type.
The flagellum, a tail-shaped feature that enables the cell to propel and move, is what makes sperm cells, or spermatozoa, tiny and motile. On the other hand, each egg cell or ovum is sizable and non-motile.
Therefore, They have unique combinations of chromosomes.

After plotting the points on the graph, analyze the results of your experiment. Conclude how different concentrations of
acid affected the solubility of the limestone. Cite evidence from the findings to support your conclusion.
Answers
There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.

scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment?
a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Answers
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

Answers
Answer:
By injecting a functioning copy of the gene mutated in Sam's DNA in the cells of his eyes. Then seeing any reactants damage the cells using a microscope.
Explanation:
The evidence that could you collect to confirm that the mutation identified in a patient's DNA causes symptoms of RP is a model organism that can be used to confirm the mutation.
What is Retinitis pigmentosa (RP)?Retinitis pigmentosa (RP) is a hereditary condition that results in cell loss and breakdown in the retina, which increases light sensitivity and causes tissue lines at the back of the eye.
The mutation is a disorder that is caused by the genetic modification of genes and chromosomes. This causes genetic disorders in the organism, and these defects may be lethal.
These diseases are hereditary, which mean they are transferred from parents to children and some genetic disease can be detected in the fetus of the mother.
Thus, a model organism, identified in Sam’s DNA, causes symptoms of RP.

Answers
Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.
What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.
