In humans, blood can be either Rh-positive or Rh-negative. Rh-positive individuals have the Rh antigen in their blood; Rh-negati

ve individuals do not. The Rh-positive allele is dominant (A) while the Rh-negative allele is recessive (a). If 84% of the population is Rh-positive, what is the frequency of the Rh-positive allele (A)

Answer:

The correct answer is: 0.60.

Explanation:

According to the Hardy-Weinberg equilibrium, the genotypic frequencies are: freq AA = p² , freq Aa = 2pq , and freq aa = q².

p refers to the frequency of the dominant allele, in this case that would be Rh-positive; while q refers to the frequency of the recessive allele, Rh-negative.

If 84% of the population is Rh-positive, that means that 16% of the population is Rh-negative (aa).

q² = 0.16

q = √0.16

q=0.4

p + q always equals 1, so:

p = 1 - 0.4

p = 0.6

Answer:

0.60

Explanation:

q2 = 0.16;

q = 0.4

Using the formula: p = 1 − q,

P = 1 - 0.4

p = 0.6

or p = 60%

Question 3
shepuryov [24]

The statements Molecule B can be used to produce molecule A and Molecules B and C interact so that amino acids can be joined together are TRUE regarding the structures shown in the diagram (Options B and E).

<h3>What are transcription and translation?</h3>

Transcription is the process by which a DNA template (molecule B) can be used to synthesize a complementary RNA (molecule A), while translation is a process in which an sequence is used as templates to generate a protein, which requires tRNAs (molecule C) to trasnport amino acids to the ribosomes.

Therefore, with this data, we can see that DNA is molecule B used to create RNA, which is molecule A, while tRNA is represented by molecule C and it is used during translation.

Describe the steps in which a gene in passed from parent to offspring. Make sure to describe how the gene is duplicated, separat
Margarita [4]

Answer:

Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state. Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division. Furthermore, chromosomes are sometimes replicated multiple times without any accompanying cell division. This occurs in the cells of Drosophila larvae salivary glands, for example, where there is a high metabolic demand. The chromosomes there are called polytene chromosomes, and they are extremely large compared to chromosomes in other Drosophila cells. These chromosomes replicate by undergoing the initial phases of mitosis without any cytokinesis (Figure 2). Therefore, the same cell contains thick arrangements of duplicate chromosomes side by side, which look like strands of very thick rope. Scientists believe that these chromosomes are hyper-replicated to allow for the rapid and copious production of certain proteins that help larval growth and metamorphosis

Nina [5.8K]

Answer:

This question is incomplete and lacks options, the whole question is:

Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as -

Options are:

A. geotropism

B. transpiration

C. phototropism

D. photosynthesis  

The correct answer is c.

Explanation:

Phototropism is known as a natural and organic movement of a plant towards the light. This is due to the natural ability of a plant to change direction based on changes in lighting in the environment. But external stimulus is not enough. It must generate some changes inside the plant that make it react in this way: hormones. A hormone is a chemical substance produced in one tissue and transported to another, in which it exerts one or more highly specific effects.Auxins are members of a group of plant hormones that are more beneficial to stimulate plant growth, it is the responsible mechanism of the response to phototropism in plants, which tends to be concentrated in the region of the stem and leaves, when a plant lacks this, it can be noted since the bending towards the light source is little or no, that is, auxins make the cells of the stem growth region (rhizomes and stems) lengthen.
