Answer:

D

Explanation:

Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.

Which reaction is most likely catabolic?
Tasya [4]

Answer: The correct answer is -

D) A ---> B + C + energy.

Explanation:

Catabolic reactions can be described as one of the two types of metabolic reaction (other being anabolic) which occur within cell when complex organic molecules are broken down to form simpler, smaller molecules.

For example - Respiration, which involves glucose breakdown in order to form carbon dioxide and water. Generally they are type of hydrolysis reactions, which include water to break bonds present in complex molecules.

Large amount of energy is also released during these reactions.

Thus, option D) shows catabolic reaction.

The four organic molecules are listed below. Which ones do you get from the foods you eat? Check all that apply.
MrRissso [65]

Answer:

Carbohydrate, proteins, and lipids

Explanation:

<em>The organic molecules that can be derived from eating foods are carbohydrate, proteins, and lipids.</em>

<u>Carbohydrates are general derived from starchy foods such as grains, proteins are derived from eating of foods that are rich in proteins such as meat, milk, etc, while lipids are derived from eating fat/oil-based foods such as butter, avocados, etc.</u>

Nucleic acids are not derived directly from foods. They are monomers of proteins and hence, they are only derived from breaking down proteins.

What is malaria?biology
Vitek1552 [10]

Answer:

Malaria can be described as a disease which is caused by a parasitic organism. The Anopheles mosquito carries the parasite Plasmodium in it. When this mosquito bites a human being, the parasite gets transferred into the blood of the person causing malaria. Before entering the blood cells, the plasmodium travel to the liver where they get matured.

Malaria is a life-threatening disease which kills many humans each year, especially people living in underdeveloped countries.
