The term "restriction fragment length polymorphism" (RFLP), which stands for individual changes (or variants) in DNA sequences at locations identified by restriction enzymes.

Botstein et al. (1980) created restriction fragment length polymorphisms (RFLPs), which employ restriction enzymes to cleave the DNA molecule at particular locations known as restriction sites, producing various fragments with varied lengths.

Restriction One technique for studying DNA used by forensic scientists is fragment length polymorphism (RFLP). The DNA strand is divided into pieces during this procedure by an enzyme. One restriction is that it struggles with dirt or mold.

A tick on a deer is an example of a relationship where one organism gains but the other is harmed.

Here the tick gets energy, but the deer loses its blood. Therefore, the option (a) is the correct answer.

Explanation:

The coelom refers to the body cavity derived from mesoderm germ layer and mainly found in multicellular animals and is positioned inside the body to surround and contain the digestive tract and other organs.

There are many advantages that coelom provides to the earthworm and the salamander. The digestive system of earthworms and salamanders is more complex, here coelomic fluid helps their body processes and assists as a hydrostatic skeleton.

The coelom's main advantage is its flexibility. The internal organs for example the heart, liver,  lungs, and intestines develop, and they help to push into the coelom. The fluid of the coelom diminishes the organs for protecting the organs and also enables them to turn, bend, shift and move. In this way, coelom helps the animals internally to finish and run the system inside in the correct way. Coelom helps the earthworms and salamanders in building the correct system and protecting their organs to maintain and enable them to function properly.

Only a small amount of the energy stored in food is available to the next organism in a food chain as a result of losses to the environment because 90% of energy is lost in the environment as heat.

A food chain is described as a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species.

A food chain also shows how organisms are related to each other by the food they eat.

We know that energy is passed up the food chain from one trophic level to the next but only about 10 percent of the total energy stored in organisms at one trophic level is actually transferred to organisms at the next trophic level. The reason for this is that he rest of the energy is used for metabolic processes or lost to the environment as heat

Pesticides and fertilizers create water and air contamination and significant health consequences. Chemicals are regulated to reduce water contamination.

Insecticides, fungicides, and nematicides are all examples of pesticides. It is essential to exercise population control over the unwanted organisms and insects that cause severe damage to the crops. On the other hand, pesticides can never be used in excess, as this would have a negative impact on living things.

Fertilizers are added to the soil in order to improve its fertility and thus the development of plants. In addition, they contain hazardous substances.

Both insecticides and fertilizers are known to include compounds that are potentially harmful. These chemicals almost certainly will lead to the contamination of water and air, in addition to causing health problems for the organisms in the surrounding area.

Contamination of water is a critical problem that has been on everyone's minds for a considerable amount of time. It is possible to lessen the amount of water contamination by lowering the amount of pesticides and fertilizers that are used.

RBC’s make up about 84% of cells in the body, but they are only 4% of body weight. Whereas, 75% of total weight are fat cells and muscle cells. They’re both large cells but constitute only a minute fraction of the total number of cells.

How many cells is the human body made of?

The exact number of cells is still debatable. But to put it briefly, around 30-40 trillion. The long answer? Not yet determined.

What we do know, is that RBC’s (red blood cells) make up the majority of cells in our bodies. They make up only 4% of total mass, despite constituting 80% of all cells. The reason is that RBC’s measure 8 micrometers in diameter.  The size of fat cells, however is around 100 micrometers.

The total number of cells to this date is still not defined, but we have a slight idea of what could be.

Therefore, the reason for RBC’s having 84% of cells and 75% of fat cells is their mass. RBC’s are only 4% of total weight because their measure is only 8 micrometers. Whereas fat cells are around 100 micrometers in diameter.

Answer: Myelin Sheath

Explanation:

In Multiple sclerosis (MS), your immune system attacks the myelin sheath or the cells that produce and maintain it. This attack causes inflammation and injury to the nerve sheath and ultimately to the nerve fibers that it surrounds. The process can result in multiple areas of scarring (sclerosis).

Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells.

The mutation results in the production of an abnormal form of hemoglobin known as hemoglobin S (HbS). Sickle cell disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.

Effects at a Protein Level:

Hemoglobin normally has a rounded shape, allowing red blood cells to flow smoothly through blood vessels. However, in sickle cell disease, the abnormal hemoglobin S causes red blood cells to become stiff and take on a crescent or sickle shape under certain conditions, particularly when oxygen levels are low.

Effects at a Cellular Level:

The sickle-shaped red blood cells are prone to clump together, leading to the formation of blood clots. These clots can block blood vessels, causing a reduction in blood flow to various organs and tissues.

Drift genetic provides a mechanism for evolution.

Option A is correct.

The variety of known evolutionary change-causing mechanisms has been substantially expanded by genetics. Most of these mechanisms are non-selective or even counter-selective, but they all involve converting variation between individuals into variance across populations over time and place.

The study of evolutionary genetics focuses on how genetics affects the course of evolution. The evolution of genomic structure is being studied in this context. It consists of population genetics and evolution combined. Genome evolution is the process by which the genome's size and structure evolve over time.

Differentiate between the lysogenic and lytic cycles The virus injects DNA into the host cell during the lysogenic cycle.

The lytic cycle includes the replica of viruses using a number cellular to fabricate greater viruses; the viruses then burst out of the cellular. The lysogenic cycle involves the incorporation of the viral genome into the host cellular genome, infecting it from inside.

Inside the lytic cycle, the viral genome does no longer comprise into the host genome. within the lysogenic cycle, the viral genome consists of into the host genome and stays there throughou The main difference among lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell while lysogenic cycle does no longer spoil the host mobile

The primary difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell whereas lysogenic cycle does not destroy the host cell.
