The pulmonary artery and right ventricle, as well as the aorta and left ventricle, are connected by semilunar valves. These valves permit blood to flow forward into the arteries but stop blood from flowing backward into the ventricles.

The aortic valve aids in maintaining proper blood flow through the heart. Blood flow to the body and the rest of the heart might be impacted by an unhealthy or damaged aortic valve.

Tricuspid valve refers to the valve on the right side of the heart that separates the upper (right atrium) and lower chambers (right ventricle).

an organism that lives inside the gastrointestinal tract and does not contain a nucleus. Based on cellular respiration, it obtains its energy through glycolysis.

Glycolysis is a series of reactions that converts glucose into two molecules of pyruvate, each with three carbons. Glycolysis is a metabolic pathway that has been around for a very long time and is used by the great majority of living things on the earth today.

In living things, the process of cellular respiration begins with glycolysis. However, since glycolysis doesn't require oxygen, a lot of anaerobic organisms—organisms that don't use oxygen—also have this pathway.

The population change so that most of the individuals have orange flowers is an example of directional selection. Thus, the correct option is A.

In population genetics, the directional selection is a mode of negative natural selection through which an extreme phenotype is favored over the other phenotypes in a population, that causes the allele frequency of that particular allele to shift over time in the direction of that particular phenotype.

A population which changes over time so that most of the individuals have orange flowers is an example of directional stabilization.

Having darker dorsal pigmentation and lighter ventral pigmentation is called countershading.

Many animals have countershading, which is characterised by a darker dorsal surface and a brighter ventral surface. Many people believe that the dorsoventral pigment polarity is an adaptive colouring for camouflage. In contrast, genetic colour polymorphism in terrestrial animals results in the frequent occurrence of noncountershaded (melanistic) morphs within a species.

Although it may also improve thermoregulation or provide UV protection, this dorsoventral pigment polarity is ecologically explained as an adaptation for camouflage through the concealment of self-shadow and/or background matching.

From the kidneys to the bladder, urine travels through these tiny tubes. The excretory organs remove some additional, frequently poisonous compounds from the circulatory fluids and expel them from the body through urine, which is a liquid or semisolid solution of metabolic wastes. Urine often reflects an organism's needs for water in terms of composition.

The difference between an object's density and that of a standard substance is its specific gravity. Depending on its value, the specific gravity might indicate whether an object will float or sink in our reference substance. A laboratory test called urine specific gravity reveals the concentration of all chemical particles in the urine.

The characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

Hemoglobin is a two-way respiratory carrier that facilitates the movement of carbon dioxide back and forth from the lungs to the tissues. Hemoglobin's affinity for oxygen in arterial circulation is high, but its affinities for carbon dioxide, organic phosphates, hydrogen, and chloride ions are low.

The 3'-end is single-stranded with a 14-16 base overhang. there are two reasons for the 3'-end being longer than the 5'-end. the first is that the g-t strand (3'-end) is extended by the telomerase enzyme. the second reason is the C-A strand (5'-end) is enzymatically degraded.

A telomere is the  region of repetitive DNA sequences at the end of a chromosome.

They protect the chromosome ends from DNA degradation, recombination, and DNA end fusions

The overhang in telomere is due to incomplete end replication.

They gets shorten during replication to avoid gene deletions.

the daughter chromosomes lose the 3′ overhang which was present in the parent and therefore, in the absence of telomerase this will accordingly result in the telomere shortening

if telomere are long, the cellular machinery result in a bit of telomere becoming looped off each time cells replicate DNA and divide,
