According to Hardy-Weinberg equilibrium, the homozygous dominant frequency equals the square allelic frequency. In the exposed example, the frequency of the class that are homozygous dominant is p² = 0.462.

To answer this question, we will assume the class is in Hardy-Weinberg equilibrium.

The Hardy-Weinberg equilibrium is a theory that states that populations that are in equilibrium are not evolving, and hence, their allelic and genotypic frequencies remain the same through generations.

Assuming a diallelic gene,

Allelic frequencies are represented as p and q

When a population is in H-W equilibrium, p + q = 1

Genotypic frequencies are,

When a population is in H-W equilibrium, p² + 2pq + q² = 1

Now, to answer this question, we will use data from the class as it was our population.

p + q = 1

Homozygous dominant frequency is p², so,

p² = 0.68² = 0.4624

The frequency of the class that are homozygous dominant is p² = 0.462.

For mаximum loаding of hemoglobin with oxygen аt the lungs, the [tex]PCO_{2}[/tex] in the lungs should be low.

Thus, the correct option is C.

The pаrtiаl pressure of cаrbon dioxide ( [tex]PCO_{2}[/tex]) is the meаsure of cаrbon dioxide within аrteriаl or venous blood. It often serves аs а mаrker of sufficient аlveolаr ventilаtion within the lungs.

Hemoglobin is contаined in red blood cells. Hemoglobin releаses the bound oxygen when cаrbonic аcid is present, аs it is in the tissues. In the cаpillаries, where cаrbon dioxide is produced, oxygen bound to the hemoglobin is releаsed into the blood's plаsmа аnd аbsorbed into the tissues.  To trigger the increased of blood flow to increase the loading of hemoglobin with oxygen in the lungs the [tex]PCO_{2}[/tex] in the lungs should be low.

Blood pressure decreases below normal levels. blood flow to the heart decreases. heart is unable to pump as much blood. blood pressure decreases even more. this is an example of positive feedback.

Less than 120/80 mm Hg is regarded to be within the normal range for blood pressure. Keep up heart-healthy routines like maintaining a balanced diet and engaging in regular exercise if your findings fall into this category.

When readings are consistently between 120 and 129 systolic and fewer than 80 mm Hg diastolic, the blood pressure is considered to be elevated. Unless action is taken to control the condition, those with raised blood pressure are prone to develop high blood pressure.

If your blood pressure continuously falls between 80 and 89 mm Hg diastolic or 130 to 139 systolic, you have hypertension stage 1. Depending on your risk of developing atherosclerotic cardiovascular disease (ASCVD), which includes heart attack or stroke, doctors will likely advise lifestyle changes at this stage of high blood pressure.

Blood pressure that continuously ranges at 140/90 mm Hg or higher is considered to be in Stage 2 hypertension. Doctors would probably advise a mix of blood pressure drugs and lifestyle modifications at this stage of high blood pressure.

Getting medical help is necessary at this point in high blood pressure. You should wait five minutes before taking another reading if your blood pressure readings suddenly rise above 180/120 mm Hg. Don't wait to call your doctor if your levels are still unusually high. It's possible that you're going through a hypertensive crisis.

Dichotomous Key: A tool used in biology to identify organisms by their characteristics, which can be used to narrow down a list of possibilities through a series of choices.

Phylogeny: The evolutionary history of a group of organisms.

Evolution: The process by which populations of living organisms change over time through natural selection, genetic drift, and other mechanisms, leading to the emergence of new species.

Charles Darwin: A British naturalist who proposed the theory of evolution by natural selection and is considered one of the most important figures in the history of science.

Linnaeus: A Swedish botanist and zoologist, who laid the foundations for the modern system of naming organisms called binomial nomenclature.

Binomial Nomenclature: A system of naming organisms using two Latin names, the first representing the genus and the second representing the species.

Homologous Structures: Structures in different organisms that have a similar underlying structure and development, but may have different functions, suggesting they have a common ancestor.

Analogous Structures: Structures in different organisms that have similar functions but a different underlying structure and development, suggesting they have evolved independently.

Vestigial Structures: Structures in organisms that have little or no function in the organism, but have a function in an organism's ancestors

Fossil Record: The remains or traces of organisms from the past, which can provide evidence for the existence and evolution of extinct species.

Comparative Embryology: The study of the developmental stages of different organisms, which can provide evidence for common ancestry.

Biogeography: The study of the distribution of living organisms and fossils across different regions and through time, which can provide evidence for the evolution of species.

Molecular Biology: The study of the molecular basis of biological activity, which can provide evidence for evolutionary relationships between species through the comparison of DNA and protein sequences.

Transitional Organism: An organism that shows characteristics intermediate between two different groups, suggesting it is a link in the evolutionary chain between them.

Anatomy: The study of the structure and organization of living organisms, which can provide evidence for evolutionary relationships between species.

Common Ancestor: A hypothetical ancestor from which two or more species have evolved, inferred from the similarities and differences in their characteristics.

To claim an evolutionary relationship between species, scientists use a combination of evidence from paleontology, comparative anatomy, molecular biology and biogeography. For example, the discovery of transitional fossils that show a gradual transition between the characteristics of two different groups of species, the similarities and differences in the DNA sequences of different species, the similarities in the embryological development of different organisms and the distribution of different species in different regions can provide evidence of evolutionary relationships between species.

Homologous structures are structures in different organisms that have a similar underlying structure and development, but may have different functions. These structures provide evidence for common ancestry because they suggest that the organisms with these structures share a recent common ancestor. Examples of homologous structures include the forelimbs of mammals, birds, and reptiles, which all have the same basic bone structure, despite being adapted for different purposes such as flight, grasping, or digging.

Competition is a form of biological interaction in which organisms compete for limited resources. The competition can be among organisms of the same species (intraspecies competition) or organisms belonging to different species (interspecies competition).

In competition, the organisms involved are both affected negatively because the limitation of resources implies that none of them can get enough for optimal growth and development.

Replacing the original population of fish from the pond and replacing them with a single species of fish means that there would be a stiff intraspecies competition within the population. This will limit the growth of the fishes as well, hence, their stunted growth.

In biological research, cycloheximide is most frequently employed for this reason.

In vitro studies on eukaryotic cells using cycloheximide to limit protein synthesis are common in biomedical research (i.e. outside of organisms). It is affordable and works quickly. Simply taking it out of the culture media quickly reverses its effects.

The statement "single cells cannot exist independently" is correct.

Cells are the basic unit of life and are essential for the functioning of living organisms. Single cells, such as bacteria and protozoa, can exist independently, but they are still dependent on the external environment for survival. For example, they need a source of energy, such as sunlight or organic matter, and a source of nutrients, such as minerals and vitamins. Single cells also have a limited set of functions and cannot perform all the functions required for survival on their own.

However, multicellular organisms, such as animals and plants, are made up of many cells that work together to perform all the functions required for survival. These cells are specialized to perform specific functions, such as digestion, movement, and reproduction. They also communicate and coordinate with each other to ensure the survival of the organism as a whole. Therefore, it is correct to say that single cells cannot exist independently.
