likoan [24]3 years ago

Answer:

B. From 200 m to the surface

Explanation:

Photosynthesis is a process which is light-dependent. Therefore, regions where light availability is not sufficient or event absent will not support photosynthesis.

In the oceans, light availability decreases with increasing depth. Below, a certain depth in the ocean, light availability becomes insufficient to support photosynthesis and this is usually below 200 m. The uppermost region of the ocean from 200 m to the surface of the ocean is sufficiently illuminated to permit photosynthesis by phytoplankton and plants. This region is called the euphotic zone.

Therefore, from the attached image, the correct option is B, since it represents the euphotic zone of the ocean.

In the lab, you use a special balloon that is permeable to water but not sucrose to make an "artificial cell." The balloon is fi
WARRIOR [948]

Answer:

The correct answer is B. water will leave the balloon.

Explanation:

As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.

A person who sprints for 45 seconds obtains most of his or her energy from _______. multiple choice
ArbitrLikvidat [17]

A person who sprints for 45 seconds will obtain most of his or her energy from muscle glycogen.

<h3>Energy metabolism during sprints</h3>

During sprinting or highly intense exercise activities, blood glucose is rapidly consumed. Rapid consumption of blood glucose may breach the blood glucose set point.

In order to maintain blood glucose homeostasis, glucose stored as glycogen in the muscles is converted back to glucose. The glucose is then utilized to produce ATP for the sprint or exercise.

Thus, a person who sprints for 45 seconds will have to obtain most of their energy from the glycogen stored in the muscles.

#SPJ1

A) muscle triglycerides.

B) plasma free fatty acids.

C) blood glucose.

D) muscle glycogen.

Which of the following statements about plant cell walls is true?
Leya [2.2K]

Answer:

<h2>A </h2>

Explanation:

1. The cell is present in some type of cells. It is found in plants and bacteria and some others. It is present or found outside the plasma membrane.

2. The functions of cell wall are that it provides tensile strength and protection to the cell against many type of stress. It also plays very important role in many others protections for the cell. There are two layer, named as primary cell wall and secondary cell wall.

3. Composition of Plant cell walls is that they are primarily made of cellulose. Cellulose fibers are linear long polymers of around  100 molecules  of glucose. These fibers cluster into bundles, known as  or called microfibrils. In plants the microtubule cytoskeleton are present, and there function is that they directs the orientation of cell wall as  in which orientation cellulose is deposited in the cell wall.

The largest proportion of the carbon dioxide delivered from peripheral tissues to the lungs is carried in the blood:
Lemur [1.5K]

Answer: The correct answer would be option a.

Explanation:

The hemoglobin in red blood cell has a tendency to bind to oxygen as well carbon dioxide in a reversible manner. It depends upon the partial pressure of the gas.

For example, at tissue site, the concentration of carbon dioxide is higher than oxygen due to which the affinity of hemoglobin increases for carbon dioxide.

In hemoglobin, carbon dioxide reacts with water to form bicarbonate ions and hydrogen ions.

At alveolar site, these ions again convert into carbon dioxide and excrete out of the blood as a part of exhale air.
