Independent assortment is the exchange of genetic material between
homologous chromosomes.
True Or False

Answers

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.

While Congress has the power to create new laws, they can be vetoed by the President. In addition, the Executive Branch must enforce these laws. What two
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

Answers

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.

Bacteria still offers its benefits. Like for example in the digestive system, they help break down food, like plant fibers. They also supply us with vitamins like biotin and Vitamin K.

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.

Answers

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.

Which form of nitrogen is most abundant on earth? N2 (Atmospheric Nitrogen) NH3 (Ammonia) NO2- (Nitrite) NO3- (Nitrate)

Answers

Answer:

N2 (Atmospheric Nitrogen)

Explanation:

Nitrogen is a chemical element positioned as 7 on the periodic table. Nitrogen is found as a gas in the atmosphere (N2) and constitutes the most part of the air making it the most abundant gas on Earth.

Atmospheric nitrogen (N2) is the most abundant of its form found on Earth. It can be converted to its compound form e.g. nitrates (a plant usable form) by lightning and some bacteria in the soil.

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

Answers

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.

Which trend in hominid evolution can be supported by fossil evidence?
Walking upright
Use of tools
Increased intelligence
Decorating cave walls

Answers

Walking upright.

You can make a case for all of them, but for three of them indirectly.

But the answer, I think, is walking upright.


You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.

Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.
