Explanation:

The color of the visible light that is reflected when the plant leaves appear as green in color is green. The chlorophyll pigments in the leaves of plants absorb the red and blue parts of the visible light spectrum.

The green part is reflected, making the leaves appear green to our eyes. Chlorophyll is a type of pigment that is found in the chloroplasts of plants. Chlorophyll absorbs red and blue light while reflecting green light. It gives the leaves of a plant their green color. The chlorophyll pigments are responsible for the green color of leaves, which are the primary site of photosynthesis in plants. They Chlorophyll absorb light in the blue and red regions of the spectrum, but reflect light in the green region. That is why leaves appear green to the human eye.

Answer:

Due to mutation of the HBB gene.

Explanation:

This causes a change in amino acids which are the building blocks of proteins.  Therefore the proteins stick together and form a fiber that changes the shape of the red blood cell making them more fragile.

Evidence that supports my explanation

People with Sickle cell anemia cannot contract malaria since they have low surface area for hemoglobin retention.

Relationship between the structure of the red blood cell and it’s function

It has a biconcave shape with a large surface area to increase space for parking hemoglobin.

To supply oxygen and remove carbon dioxide, the circulatory and respiratory system works together.

The respiratory system is what aids in breathing in oxygen and breathing out carbon dioxide. The circulatory system is the system that assists in supplying tissues with oxygen from the lungs and in removing carbon dioxide from the tissues by way of the lungs. In this way, both of these processes assist in the supply of oxygen and the removal of carbon dioxide as waste.

The blood that carries waste (CO₂) from the tissue via the heart will first carry the oxygen inhaled to the lungs, where it will be exchanged with the blood. The oxygen will then be sent to the heart, where it will be used to pump oxygen-rich blood to the tissues. Additionally, blood that has lost oxygen will transport waste from the tissue.

Artificial selection is a contrast to natural selection.

Natural selection is the process by which populations of organisms adapt and change. Individuals within a population are inherently variable. In other words, all individuals are different in some way. This variation means that some individuals have traits that adapt better to their environment than others.

Natural selection is the selection process that occurs as a result of an organism's ability to adapt to its environment. Artificial selection, on the other hand, is selective breeding imposed by an external entity, usually a human, to increase the abundance of desirable traits.

Examples of natural selection include : Selection of long-necked giraffes.

Examples of artificial selection include : Breeding different breeds of dogs and cows to produce the desired breed.

The ribosomes ceased working when a cell was exposed to a certain substance. Protein synthesis is the first cell activity influenced by this alteration in ribosome function.

As a result, B is the right answer.

Cells are the fundamental structural components of all living things. Ribosomes are specialized structures found inside cells that manufacture proteins. A eukaryotic cell's protein production is comprised of two processes: transcription and translation.

The transcription process occurs in the nucleus, where information from a DNA strand is transcribed into a single-stranded messenger RNA (mRNA) molecule by the RNA polymerase enzyme.

During the termination of transcription, the completed mRNA strand detaches from DNA, exits the nucleus, and enters a cytoplasmic ribosome. Translation happens at the ribosome, where the genetic code in mRNA is read and protein is made.

Cells require these proteins to accomplish vital processes such as mending cellular damage, maintaining cellular structure, producing hormones, and dividing cells.

Double-stranded viral DNA is incorporated into a host cell as a form of genetic material.

The viral DNA is packaged within the viral capsid and is released into the cells of the host organism when the virus enters the cell. Once inside the cell, the viral DNA is uncoated and then incorporated into the host cell's own genetic material. This process, known as “genetic transformation”, is how the virus replicates its genetic material and spreads to other cells.

The incorporation of viral DNA into a host cell is an essential part of how viruses spread and cause disease. The viral DNA is able to take control of the host cell's normal cellular functions and cause it to produce more viral particles.

This process, termed “lytic cycle”, is necessary for the virus to spread and cause infection. In some cases, the viral DNA also integrates into the host cell's genome, allowing the viral genetic material to be passed down through generations of cells. This process, referred to as “lysogenic cycle”, can lead to persistent infections and chronic diseases.

In order to successfully incorporate its DNA into the host cell, the virus must first attach to the host cell's membrane. This is done by the virus making use of specific proteins known as “receptors” that are found on the cell's surface. When the virus attaches to the receptor, it is allowed to enter the cell. Once inside the cell, the viral DNA is then uncoated and incorporated into the host cell's own genetic material.

Reduction of fluid losses at the kidneys due to the retention of Na+ is the action of a hormone called aldosterone. So option c is correct.

Aldosterone is a steroid hormone produced by the adrenal glands that plays a crucial role in regulating electrolyte balance in the body.Aldosterone works by stimulating the kidneys to reabsorb more sodium ions (Na+) and water, and to excrete more potassium ions (K+). This results in an increase in blood volume and blood pressure, as well as a decrease in urine output.

By retaining more sodium ions, aldosterone helps to maintain the body's fluid balance and prevent dehydration.Aldosterone secretion is regulated by the renin-angiotensin-aldosterone system (RAAS), which is a complex feedback mechanism that responds to changes in blood pressure and electrolyte levels. When blood pressure drops or when the body loses too much sodium, the kidneys secrete the enzyme renin, which converts angiotensinogen to angiotensin I. Angiotensin I is then converted to angiotensin II by the enzyme ACE, which stimulates the release of aldosterone.
