Explanation:
In snapdragons, flower color is determined by a gene with two alleles. Red flower color (R) shows incomplete dominance over the gene for white flower color (R'). A scientist is observing the genes and genotype of a snapdragon population. Which observation provides evidence that the population is evolving?
A) The alleles R and R' have unequal frequency in the population.
B) The population is decreasing, and the allele frequencies remain the same.
C) The allele R' is becoming more common in the population.
D) The population is increasing, and the allele frequencies remain the same.
Answer:
C) The allele R' is becoming more common in the population.
The observation from this experiment provides the evidence that the population is evolving and the allele R' is becoming more common in the population. Thus, the correct option is C.
What is Incomplete dominance?Incomplete dominance is the form of gene interaction which results from a cross in which each of the parental contribution is genetically unique and the allele gives rise to progeny whose phenotype is intermediate of the two parental genotypes and phenotypes. Incomplete dominance is also referred to as semi-dominance or partial dominance. It is an exception of the Mendel's law of dominance.
From the observation made in the experiment, it can be said that the allele R' which is responsible for white colored flowers in the plant are becoming more common in the population.
Therefore, the correct option is C.

Independent assortment is the exchange of genetic material between
homologous chromosomes.
True Or False
Answer:
False
Explanation:
According to Gregor Mendel in his law of INDEPENDENT ASSORTMENT, independent assortment of genes is a phenomenon whereby the segregation of the alleles of one gene into gametes occurs independently of the alleles of another gene i.e. their segregation does not affect/influence one another. Independent assortment occurs in the Metaphase 1 of meiosis 1, where homologous chromosomes randomly align at the equator of the cell. This random orientation of homologous chromosomes determines which chromosome will separate into which gamete.
According to the question, the exchange of genetic material between homologous chromosomes is termed CROSSING-OVER. Crossing over or Recombination occurs during the Prophase I state of meiosis I, where non-sister chromatids of homologous chromosomes exchange a portion of their gene.
Hence, the answer is false because the exchange of genetic material between homologous chromosomes is crossing-over.
Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

different constitutional principles are demonstrated by these relationships?
Select one:
A
checks and balances and separation of powers
B.
separation of powers and eminent domain
C
federal supremacy and due process
D.
separation of powers and quartering of troops
Answer:
A, Checks and balances and separation of powers.
Explanation:
Answer:
The correct answer is:
checks and balances and separation of powers
Explanation:
The system of checks and balances refers to instances in which the powers of the branches of government overlap, such as the Executive and the Legislative branch both having some power over the acts passed by Congress. Separation of Powers refers to instances in which separate branches have completely separate responsibilities, as in creating, interpreting, and enforcing the laws. Both of these doctrines are in place to ensure no branch gains too much power.

Which would a microscope be LEAST useful in studying?
A. spider
B. amoeba
C. bacterium
D. paramecium
Answer:
A
Explanation:
spiders can be seen with the naked eye
Answer:
A
Explanation:
A spider is large enough to see and observe without a microscope. Bacteria, amoeba and paramecium are all very tiny, and can’t be seen with just our eyes. To see these things, we would need a microscope. Therefore, a microscope would be the least useful when studying A: a spider.

Compare a lunar eclipse and a solar eclipse. For each type of eclipse, be sure to provide evidence that describes:
The alignment of the sun, moon and earth during the eclipse.
The phase of the moon that is observable during the eclipse.
How the sun’s light is being blocked on the earth and the moon.
Type your answer on a Google doc and submit
Answer:
A lunar eclipse occurs when the Earth gets in the way of the sun and blocks sunlight from hitting the moon. This makes the moon have a reddish-orange tint to it. A full moon is visible during a lunar eclipse.
A solar eclipse happens when the moon gets in between the sun and the Earth, forming a crown like ring around the moon, which is from the sun. The moon itself might not be visible, due to the angle at which it sun is hitting it at.
