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.

Human development is an important factor in the process of maturation because it provides a biological framework of how much one is capable of accomplishing.

Maturation is an important part of human development, as it is the process by which individuals transition from childhood to adulthood. As such, it is essential for individuals to understand the biological framework of how much one is capable of accomplishing in order for them to reach their full potential.

Biological maturation plays a critical role in the developmental process by providing a biological framework of how much one is capable of accomplishing. This framework is composed of a variety of factors, such as the person’s physical characteristics, hormone levels, and brain development.

These factors determine how much a person is capable of learning, understanding, and doing. For example, a person’s hormone levels can influence how quickly they can learn new skills, while their brain development can influence how well they can recall information.

when one human cell 46 DNA molecules divides by mitosis, the cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

What is Mitosis?

Mitosis is a type of cell division in which a cell (mother cell) divides to produce two new cells of her (daughter cells) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the mitotic process in which the DNA in the cell's nucleus is divided into her two equal sets of chromosomes.

The purpose of mitosis is to form more diploid cells. It works by copying each chromosome and spreading the copies out on different sides of the cell.

Mitosis is required for growth, repair, and asexual reproduction. It plays an important role in the development of organisms. In unicellular organisms, mitosis is thought to be the process of asexual reproduction.

This causes the green color of leaves to fade, revealing other pigments that have been present in the leaf all along.

As the volume of a cell increases, so does its need for nutrients. This is because larger cells require more energy, as well as more materials, to sustain their increased size. In order to keep up with the increased demand for energy, larger cells must absorb more nutrients, including proteins, carbohydrates, lipids, and other essential molecules.

The two primary methods by which cells acquire nutrients are diffusion and active transport. Diffusion is a passive process that occurs when molecules move from an area of higher concentration to an area of lower concentration. This process occurs in cells and can provide the necessary nutrients for growth and maintenance. However, diffusion becomes increasingly inefficient as the cell size increases due to the increased distance the molecules must travel.

Active transport, on the other hand, is an energy-driven process in which molecules are actively transported into the cell from an area of lower concentration to an area of higher concentration. This process allows for the rapid transport of larger molecules and the more efficient uptake of nutrients. As the volume of the cell increases, more active transport is needed to provide the necessary nutrients. This can be seen in the process of endocytosis, where the cell engulfs nutrients from the environment and transports them into the cell.

The role of the respiratory system is to help in gaseous exchange and the role of the circulatory system is to supply oxygen and remove carbon dioxide from the tissue.

The respiratory system aids in the inhalation of oxygen and the exhalation of carbon dioxide. Additionally, the circulatory system is the system that aids in removing carbon dioxide from tissues by way of the lungs and supplying oxygen from the lungs to tissues. This method of oxygen supply and carbon dioxide waste removal is made possible by both of these processes.

The oxygen that is inhaled first travels to the lungs where it is exchanged with the blood that carries the waste (CO₂) from the tissue via the heart. From the heart, the oxygen in the oxygenated blood is delivered to the tissues.  And the deoxygenated blood tissue carries the waste products from the tissue.
