The correct answer is D Vitamin D. The lack of this vitamin alters bone maturation and development.
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.

This is an example of competitive exclusion. Over many generations, Gentoo penguins in another area adapt to feed on krill at greater depths than the Chinstrap penguins. This is an example of adaptive radiation.
Competitive exclusion is a principle in ecology that states that two species that occupy the same niche cannot coexist indefinitely. If one species is better adapted to the environment and has a competitive advantage over the other, it will outcompete the other species and drive it to extinction. This is what appears to have happened in the case of the Chinstrap and Gentoo penguins. These two species occupy the same area and have the same food source, which means that they are competing for the same resources. Over many generations, the Chinstrap penguins, which are better adapted to the environment, were able to outcompete the Gentoo penguins and drive them to local extinction. Adaptive radiation, on the other hand, is the evolution of a single species into multiple species that each occupy a different niche. In the case of the Gentoo penguins, it appears that they were able to adapt to feeding on krill at greater depths than the Chinstrap penguins. This allowed them to occupy a different niche and coexist with the Chinstrap penguins without competing for the same resources. Adaptive radiation can occur when a species colonizes a new area with a variety of available niches or when a species evolves to exploit a new resource. In both cases, the species is able to diversify and occupy a variety of niches, allowing it to coexist with other species that occupy different niches.

a. True
b. False
Answer:
A
Explanation:
Hunger, fullness, and energy balanced are regulated by the hypothalamus. Hunger and fullness signals, in the form of hormones, travel through the bloodstream from tissues that consume energy to the brain. The hypothalamus is the region where these neuronal and hormonal signals integrate. After the reception of this signals the hypothalamus orchestrates a signaling cascade containing other hormones to create the hunger sensation.
b. The cuticle provides protection against predators.
c. The cuticle prevents water loss in a terrestrial environment.
d. The cuticle allows for improved gas exchange.
Answer: c. The cuticle prevents water loss in a terrestrial environment.
Explanation:
The earthworms have a thin cuticle outside their epidermis. The cuticle performs different functions in the worm body. The cuticle protects the worm from predators. The thin cuticle remains moist with the slimy mucus. The cuticle helps in the exchange of gases from the external environment. The cuticle helps in absorbing the oxygen from the external environment whereas it expels the carbon dioxide to the external environment. The cuticle prevents the loss of moisture and allows the gaseous exchange which facilitates the survival of the worm in a harsh terrestrial environment.
Life is a match. Where we are born in the world to be good and righteous. If death is when our lives are powerless. After life we all must die and after death there is Eternal Life, which is the hereafter. If our deeds are right, we will definitely go to heaven. If our actions are evil, it will be hell.
