If a gene has two alleles, and allele A has a frequency of 83 percent, then allele a has a frequency of:_______

Answers

Answer:

Another allele frequency = 17%

Explanation:

Given:

Allele A has a frequency = 83 percent

Find:

Another allele frequency

Computation:

Sum of percent = 100%

So,

Another allele frequency = 100% - 83%

Another allele frequency = 17%

In what way do two alleles for the some trait differ?


A. The are found on different chromosomes.

B. They consist of different sequences of DNA

C. They are produced by two different people.

D. They are complementary.

Answers

Answer:

B. They consist of different sequences of DNA

Explanation:

Alleles are contrasting or alternative forms of a gene. A diploid organism i.e an organism with two sets of homologous chromosome, contains two alleles for each gene that encodes a trait. Although the two alleles of that particular gene encodes the same trait, they can encode different phenotypes i.e way it is expressed because they contain different sequences of DNA.

For example, in a gene coding for height in pea plants, two alleles, T and t are responsible. Allele T codes for tall height (phenotype) while allele t codes for short height (phenotype). Although the two alleles are for the same trait, they differ in the content of their DNA sequence, hence, are expressed differently or variably.

In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.

Answers

Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular respiration or aerobic respiration is a series of chemical reactions which begin with the reactants of sugar in the presence of oxygen to produce carbon dioxide and water as waste products.

Glucose + Oxygen ------> ATP + Carbon dioxide + Water

C6H12O6 + 6O2 ----------> 36ATP + CO2 + H2O

The chemical equation for cellular respiration shows that plants cycle matter because oxygen and glucose that is produced by the plants is used by the human body for the generation of energy in the form of ATP molecules, water and carbondioxide gas.

This carbondioxide gas is released by animals which is used by the plants in order to make their own food during the process of photosynthesis so we can conclude that the chemical equation for cellular respiration shows that the plants cycle matter.

Answer:

under the ground in volcanoes

Explanation:

There are some volcanically active spots that are in the middle of a tectonic plate.

The interior of the Earth is hot, while the surface or crust of the planet is cold. Between these layers are areas of molten rock. These molten rocks are less dense, so they easily break through cracks in the Earth's crust.

Magma is molten rock and is found beneath Korea. Beneath the volcano, in the underground spaces, magma accumulates.

Is hemoglobin a hormone?

Answers

Answer:

I'm really sorry it is not.

A new hormone called erythroferrone, which regulates the iron supply needed for red blood-cell production, has been discovered by researchers. Iron is an essential functional component of hemoglobin.

Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the "building blocks" of proteins.
