A student proposes that left-handedness is a recessive trait and is hidden in much of the human population. a survey of his clas

The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.

<h3>What is the Hardy Weinberg principle?</h3>

The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.

The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).

This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and  q^2 the recessive homo-zygous frequency.

In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Which of the following is an accurate description of an adult stem cell?
ELEN [110]

Answer;

C. Multipotent

Explanation;

-Multipotent cells are those cells that can develop into more than one cell type, however, they are more limited than pluripotent cells. Adult stem cells and cord blood stem cells are considered multipotent.

Totipotent cells on the other hand, are those cells that can form all the cell types in a body, together with the extraembryonic, or placental cells. Embryonic cells are the only cells that are totipotent within the first couple of cell divisions after fertilization.

Pluripotent cells are those cells that give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.

Question 7 of 34
alexandr1967 [171]

Answer:

B. Excretory system

Explanation:

<em>Because the excretory system is made to remove urine which consists of waste materials such as excess salts and water. The kidneys are present in it as well. If there is too much water in the body the excretory system will produce urine with higher water concentration so whiteish urine will be produced and if there is a low amount of water in the body the excretory system will produce urine with lower water concentration so yelloish or greenish urine will be produced</em>

Eutrophication can cause excess algae growth. Which of the following describes how nutrients contribute to eutrophication?
dusya [7]

Eutrophication of water bodies like lake, pond, shallow stretches of river, etc. is the phenomenon where excess growth of vegetation on the surface of the water takes place. This excess growth results in the clouding of the water, depletion of dissolved oxygen in water, and the death of aquatic organisms. The primary reason for the cause of eutrophication is the presence of nutrients in excess amounts in the water. The nutrients B. come from fertilizer and sewage runoff.
