The body's response to high elevations is a great example of homeostasis because it shows how the body can maintain stable internal conditions despite changes in the external environment by initiating various physiological responses.

Homeostasis is the process by which the body maintains a stable internal environment despite changes in the external environment. When we go to high elevations, the air pressure decreases, which causes a reduction in the partial pressure of oxygen. This change in the external environment can have significant effects on the body, such as hypoxia or altitude sickness.

To maintain homeostasis, the body initiates several physiological responses to cope with the decrease in oxygen availability at high elevations. These responses include increased respiration, increased heart rate, and increased production of red blood cells.

All of these responses work together to maintain the body's oxygen supply and prevent hypoxia, which is a state of insufficient oxygen supply to the tissues. By maintaining adequate oxygenation, the body can function normally despite the change in the external environment. Therefore, the body's response to high elevations is a great example of homeostasis.

The nutrient which provide more energy is C. Lipids

Among the given options, lipids provide the most energy per unit mass. Lipids, also known as fats, are a concentrated source of energy in the diet. When metabolized, lipids yield approximately 9 kilocalories (kcal) of energy per gram.

Carbohydrates, including sugars and starches, provide approximately 4 kcal of energy per gram. They are a readily available source of energy for the body, particularly for short-term energy needs. Proteins also provide approximately 4 kcal of energy per gram. However, their primary role is not as an energy source but rather as the building blocks for tissues, enzymes, and other important molecules in the body.

Vitamins, on the other hand, do not provide significant energy. They are essential for various biochemical processes in the body but do not contribute directly to energy production.

It is important to note that while lipids provide the most energy per gram, the overall balance and variety of nutrients in a diet are crucial for maintaining optimal health. Nutrient needs vary based on individual factors, such as age, sex, activity level, and overall health goals. Therefore, Option C is correct.

Plasmolysis is the loss of water by plant cells after being placed in a solution with a higher concentration of solute than the cells. This is called a hypertonic solution. Osmosis causes water to flow from the cell into the surrounding liquid.

Plasmolysis is the process by which cells lose water in hypertonic solutions. When cells are in a hypotonic solution the reverse process cytolysis or cell lysis occurs resulting in a decrease in external osmotic pressure and a net flow of water into the cell. When plants are not watered the extracellular fluid becomes isotonic or hypertonic causing water to leave the plant cells.

This causes a loss of turgor pressure. You will probably notice it as a wilt. In more concentrated solutions cell contents lose water by osmosis. They contract and move away from the cell wall. Cells are limp It is cytolyzed. When a high concentration of salt is placed on the outside of the cell membrane water leaves and binds with the cell. As water is lost by this movement, the plant cells shrink and die. Because of this, salt can kill plants. It leaches water out of the cells.

Answer:

transcription initiation

Explanation:

Transcription is a process by which genetic information from DNA is used to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently utilized to synthesize a protein by a process called translation. Transcription in prokaryotes has three steps:

1-Initiation: the RNA polymerase is a multisubunit enzyme (holoenzyme) composed of two α, one β, one β’ and one ω and σ subunits (α2ββ’ωσ). This holoenzyme binds to the promoter region of the template DNA strand.

2-Elongation. The sigma σ factor of the holoenzyme is released and the complex and the core enzyme (α2 ββω) moves along the template strand, thereby producing an mRNA sequence

3-Termination. This step can be Rho-dependent, where a protein named "Rho" recognizes the termination site and stop transcription, and Rho-independent (transcription continues until the termination sequence is reached).

In consequence, Rifamycin is likely to block the initiation of transcription because the core RNA enzyme needs to bind the sigma factor (σ) for initiation of transcription in bacteria.
