In humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rh factor, is controlled by a single gene and is either present or missing from the red blood cells. If present, the individual has the Rh+ phenotype. If missing, the individual has the Rh− phenotype. Rh+ is the dominant to Rh−. Suppose that, in the Yoruban population, the frequency of the Rh− phenotype is 0.01.0.01. Using the Hardy–Weinberg equations, calculate the frequency of the Rh+ allele to at least two decimal places.

the answer would be that the frequency of the allele Rh + = 0.6

Explanation:

the frequency of the Rh value is incorrect, the value must be expressed in an integer that can have decimals but not a meaningless numerical sequence(0.01.0.01?), however, an exercise is performed taking the frequency value 0.16 as an example for the development of subsequent

we can start from the formula taking into account that the population is in Hardy-Weinberg equilibrium

 p2 + 2pq + q2 = 1.0

the above is based on the fact that

p2 is considered as the dominant homozygous ratio

q2 as the proportion of recessive homozygotes

2pq as the proportion of heterozygous individuals

knowing that the Rh phenotype is recessive and has a value of 0.16, we replace obtaining

q2 = 0.16 or q = 0.4

where solving the equation

p + q = 1

p = 1- 0.4 = 0.6

the answer would be that the frequency of the allele Rh + = 0.6

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
