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.

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.

Answers

Answer:

Exposure to sunlight.

Explanation:

Sunlight is important condition necessary for the presence of Marine life in ocean. This is because sunlight provide energy for ocean current and wind waves. When this energy is converted to heat, it a layer of warm water which is present at the ocean surface which support most Marine life. Sunlight produce light energy which is needed for Marine life like algae to photosynthesized in addition with carbondioxide and water in order to to produce necessary for survival for most Marine life.

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.

Kyree is heterozygous. |f(W) ) is for waves, and ) if for no wave (w) r no waves What is Kyree's genotype & phenotype?

Answers

Answer:

Kyree b will have waves with a gwnotyoe; We

Explanation:

This question involves a single gene coding the possession or not of waves in humans. Allele W is for possession of waves while allele w is for no waves.

Heterozygous means contains two different alleles of the same gene. In this case, an heterozygous individual will possess allele W and w together i.e. Ww. Since the allele W is dominant over allele w i.e. can mask Its phenotypic expression, an heterozygous offspring (Ww) will phenotypically possess waves.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.

It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?

Answers

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.
