This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.

Answer:
a. Sucrose is present in the plant cells that provide them energy and helps in the metabolic process of the plants. The pH of the plant cells will increase and their cellular environment becomes basic in nature. The uptake of sucrose is pH specific and the acidic condition in the environment allows the uptake of sucrose. The decrease in pH concentration in the environment increases the pH inside the cells.
b. The inhibitor of ATP inhibits the production and functioning of the ATP molecule. This effects the sucrose transport in the plant cells. As the sucrose movement requires the ATP and it is a active transport. The ATP inhibition decreases the sucrose uptake in the plant cells and the sucrose concentration decreases inside the plant cells.
Sucrose uptake in plant cells seems to require an acidic environment, brought about by the active transport of protons which requires ATP. An inhibitor of ATP regeneration would likely slow or stop this transport and, in turn, sucrose absorption.
The reported results suggest that the process of sucrose uptake in plant cells involves acidification of the surrounding medium prior to sucrose absorption. This can be explained by the proton-sucrose symport mechanism, in which protons (H+ ions) are actively pumped out of the cell in a process that requires ATP energy. When these protons combine with water (H2O) in the cell's environment, they form hydronium ions (H3O+), resulting in a lower pH or more acidic environment. Only after this acidic environment is established does sucrose uptake begin.
Based on this mechanism, introducing an inhibitor of ATP regeneration would be expected to decrease or halt this process, since ATP is required for the active transportation of protons. With less ATP, fewer protons will be pumped out, leading to a less acidic environment and, thus, lower sucrose uptake. This hypothesis is supported by how phosphofructokinase, a key enzyme in glycolysis (ATP production), is affected by low pH levels.

Yes
Explanation:
After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease
Answer:
terrestrial or aquatic.
Explanation:
All types of ecosystems fall into one of two categories: terrestrial or aquatic. Terrestrial ecosystems are land-based, while aquatic are water-based. The major types of ecosystems are forests, grasslands, deserts, tundra, freshwater and marine.
