Answer:
this refers to the process of using customer or employee feedback to create a better product or workplace.
Explanation:
The gene that causes sickle cell disease is present in a higher percentage of residents of sub-Saharan Africa than among those of African descent living in the United States. This gene provides some protection from malaria, a serious disease that is widespread in sub-Saharan Africa. Discuss an evolutionary process that could account for the different percentages among residents of the two regions. (See Concept 1.2 .)
The evolutionary process that accounts for the different sickle cell allele ratios is stabilizing selection in endemic malaria areas.
What is stabilizing selection?Stabilizing selection is a special class of natural selection that acts to maintain the frequency of a harmful allele in the population because it confers some type of adaptive advantage to the individuals in the population.
In this case, the allele for sickle-cell anemia can be harmful when it is homozygous individual but it is beneficial in heterozygous individuals because it allows them to resist malaria disease, and therefore this allele is maintained by a special class of stabilizing selection on the population.

Predict what would happen if you injected a water-soluble hormone directly into the cytosol of a target cell.
The water-soluble hormone's receptor is located on the surface of the target cell, thus when it is injected into the cytoplasm of the target cell, a biological response is not elicited.
A lipophobic hormone that cannot diffuse through the cell membrane and bind to its specific receptors produced on the surface of the target cell membrane is known as a water-soluble hormone.
For instance, the adrenal gland, which is situated on top of the kidneys, secretes the water-soluble hormone adrenaline.
A cellular reaction is brought on by the activation of an enzyme when a water-soluble hormone binds to a receptor found on a protein found on the surface of a cell. Cell-surface receptors can direct protein transport from the cytoplasm to the nucleus and control the transcription of a particular gene.
Because the receptors for water-soluble hormones facing the extracellular space are found on the cell surface, when a water-soluble hormone, such as adrenaline, is injected into the cytoplasm of the target cell, the hormone is unable to attach to its receptor.
Therefore, no biological reaction would be set off.

The Hardy-Weinberg theory states that as long as a population has the same allelic and genotypic frequencies through generations, it is in equilibrium, and is not evolving. This population IS EVOLVING.
What is Hardy-Weinberg equilibrium?
The Hardy-Weinberg equilibrium theory that states that when a population is in equilibrium, it is not evolving.
The allelic frequencies in a locus are represented as p and q.
Assuming a diallelic gene,
Alleic frequencies,
The frequency of the dominant allele p(X) is pThe frequency of the recessive allele p(x) is qThe genotypic frequencies after one generation are
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium. As long as they remain the same, the population is not evolving.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example, we need to see if the population is evolving or not.
To do it, we will take the genotypic and allelic frequencies of the current generation, and then we will take the expected genotypic frequencies for the next generation to compare them and see if they are the same or different.
Diallelic gene
Dominant allele VRecessive allele vPopulation size = 120 individuals
VV individuals = 16Vv individuals = 92vv individuals = 12Genotypic frequencies (current generation - observed data)
F(VV) = p² = 16/120 = 0.1333
F(Vv) = 2pq = 92/120 = 0.7667
F(vv) = q² = 12/120 = 0.1
Allelic frequencies
f(V) = p = p² + 1/2 2pq = 0.1333 + 0.7667/2 = 0.5166
f(v) = q = q² + 1/2 2pq = 0.1 + 0.7667/2 = 0.4833
According to these allelic frequencies, the expected genotypic frequencies for the following generation would be as follow,
F(VV) = p² = 0.5166² = 0.2668 ≅ 0.267
F(Vv) = 2pq = 2 x 0.5166 x 0.4833 = 0.499
F(vv) = q² = 0.4833² = .02335 ≅ 0.234
And the expected numbers of individuals from the following generation expressing each gentoype would be,
VV = 0.267 x 120 = 32
Vv = 0.499 x 120 = 60
vv = 0.234 x 120 = 28
As we can see, genotypic frequencies change from one generation to the other. We can assume that this population is not in H-W equilibrium and, hence, it is evolving.
p₁² ≠ p₂²
0.1333 < 0.267
2pq₁ ≠ 2pq₂
0.7667 > 0.499
q₁² ≠ q₂²

The production of carbon dioxide during respiration in aerobic tissues lowers the ph in erythrocytes, which in turn ________ the affinity of oxygen binding to hemoglobin.
The production of carbon dioxide during respiration in aerobic tissues lowers the ph in erythrocytes, which in turn decreases the affinity of oxygen binding to hemoglobin.
During internal respiration, carbon dioxide in erythrocytes combines with water to form carbonic acid, which then associates with hydrogen ions and bicarbonate ions. Bicarbonate ions get diffused out of erythrocytes and control the blood ph. Hemoglobin in the RBCs binds with hydrogen ions and reduces the affinity for oxygen. Oxygen then gets diffused out of the RBCs and enters the tissues. The interaction between hemoglobin and hydrogen ions and then its affinity for oxygen is called the Bohr effect.
Internal respiration results in the production of carbon dioxide in aerobic tissues that lowers the oh in erythrocytes through bicarbonate ions. This, in turn, decreases the affinity of oxygen binding to hemoglobin and releases it into the aerobic tissues.

one population of a species has 25 individuals, all with genotype aa; a second population of this species has 40 individuals, all with genotype aa. assume that these populations live far apart but in similar environmental conditions. based on this information, the observed genetic variation most likely resulted from .
Genetic drift is an evolutive force that affects small populations and changes their allelic and genotypic frequencies by randomly fixating some alleles and eliminating others. Option A) Genetic Drift.
What is genetic drift?Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population.
Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly attach one of the alleles.
Two events that involve genetic drift are the bottleneck effect and the founder effect.
Now we need to define which option is the best.
We have two small populations (25 and 40 indviduals)One of the populations is AA while the other one is aaThey are separated and far away from each otherThey are under equal environemntal conditionsWhat happened?
Gene flow
This is not the case, because gene flow decreases heterogeneity between populations, reducing genetic variation. Besides if these populations are far away, gene flow would be difficult.
Nonrandom matings
This is not the case, because with nonrandom mating there would not be such a change in frequencies.
Directional selection
Directional selection does not seem to be the cause either, because both populations are under the exact same environmental conditions, so pressures acting on them are the same. There is no change in this aspect.
Genetic Drift
I believe this is the best option. Genetic drift causes a change in allele frequencies and affects small populations. These populations might have been separated for a long time, and suffered the effects of genetic drift. It might be a founder effect case, with the smaller population being the newest one.
The correct option is Genetic Drift. Option A.
