Vladimir79 [104]

Answer:

A. The infant will maintain an adequate fluid balance.

Explanation:

It is urgent for the nurse to achieve the hemodynamic stability with the administration of dopamine, diuretics, calcium and baking soda

It is fundamental to seek the balance between transport and consumption of oxygen to the tissues, with the inversion of the anaerobiosis of the tissues

Robins typically lay four eggs. Four eggs allow the offspring to be well fed, whereas larger clutches may result in malnourished

Amanda [17]

Answer:

Stabilizing selection

Explanation:

The process of natural selection selects a species in one of the three ways: stabilizing selection, directional selection and disruptive selection.

During the process of stabilizing selection, nature does not favour the extreme phenotypes of the population but the intermediate phenotype with the maximum number of population.

In the given question, the Robin laid four eggs, neither more than four nor less than four which could have more disadvantages than the advantages. Since the intermediate number of eggs is favoured by nature therefore the stabilizing pattern is observed.

Thus, Stabilizing selection is correct.

A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased per

chubhunter [2.5K]

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,

SD = X₀ - Xs

Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.

h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.

R = h²SD

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),

R = X₀ - X₁

-------------------------------------------------------------------------------------------------------------

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:

You are selecting rice´s decreased period of maturation.
The population of rice has a mean maturation time of 30 days → X₀
Parental selected average period to maturation is 25 days → Xs
F1 plants mature on average in 27 days → X₁
N arrow sense Heritability → h²

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs - X₀

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5

h² = 0.6
