What happens if oranisms fall to adjust and respond to changes in their environment?

Answer:

There are two main life zones in the ocean. The first one is the coastal zone - the zone near the coast. In this zone, tides expose some part of the see bottom for some part of each day, so some of the organisms in this part can live both under the water and dried out for hours. Also, this part of ocean characterize higher temperature and higher amount of nutrient-rich matter that supports life. Therefore the 90% of all sea lives in the coastal zone. The second zone is the open sea which include the rest of the ocean away from the land. It can be divided in two parts: neretic zone, in which sunlight penetrates the whole water column and oceanic zone, which is characterized by darkness and very high pressure.

Explanation:

The cell will not be able to depolarize due to unavailability of sodium ions.

What is the role of sodium gates in action potential?

• Sodium voltage-gated channels can be either closed, open, or inactive.

• Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.

• Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.

• Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.

• A greater amount of sodium will enter the cells as a result, initiating an action potential.

• Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.

• The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."

Answer:

it could not depolarize because the cell cannot become more positively charged.

Explanation:

When sodium gates open, depolarization occurs, changes the charge of the ion from negative to positive. Therefore, if the sodium channels no longer open, the flow of sodium into the cell that changes the charge from - to + and depolarization would not occur.

True

Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body

Some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching

There are four major blood groups determined by the presence or absence of two antigens: A and B on the surface of red blood cells

In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present or absent creating the 8 most common blood types which are A+,A-.B+,B-O+,O-,AB+,AB-

Blood type is inherited and it is determined by the blood type of both father and mother

Blood type helps in DNA fingerprinting and forensic science and plays an important role in determining blood relations or to identify the suspect

The balloon got smaller because the pressure of the water around it increased compared with the pressure inside the balloon. Therefore, the correct answer is (C).

As the student submerged the balloon to various depths, the pressure of the water around the balloon increased, which caused the balloon to get smaller. This is because the pressure inside the balloon remained constant, while the pressure outside increased.

The helium inside the balloon would have been compressed by the increased pressure of the water, causing the balloon to decrease in size. This phenomenon can be explained by Boyle's law, which states that the volume of a gas is inversely proportional to the pressure of its surroundings.

Answer:

Glycogen is produced by animals while starch is produced by green plants

Explanation:

Following are the differences between starch and glycogen-

1. The structure of starch is larger as compared to that of glycogen. Glycogens has one molecule while starch has two molecules of glucose

2. Glycogen is produced by animals in their liver, muscles, brain, uterus etc. therefore it is also known as animal starch while starch is produced by green plants.  

3. Glycogen has only branched structure while starch has both branched and chain structure.
