If a plant has a high concentration of minerals inside its root cells, but does not have enough energy for active transport, wha

inna [77]

Answer:

The minerals will not be move or transported to other part of the plants because active transport require energy.

Explanation:

Active transport is a process where molecules and ions are move against a concentration gradient by using energy.

This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.

If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.

What happens when nutrient levels become too concentrated in rivers, lakes, and oceans?

Reika [66]

Answer:

Eutrophication is what happens when nutrient levels become too concentrated in rivers, lakes, and oceans. Eutrophication is when the levels of nutrients and minerals in a body of water become too concentrated. It is usually induced by the release of nitrate or phosphate-containing substances into a water body.

What molecules do organism use to store energy

Andreas93 [3]

<h2>ANSWER:</h2>

Glycogen and triglycerides

<h2>EXPLANATION:</h2>

Living organisms employ two main kinds of energy storage. Energy-rich molecules such as glycogen and triglycerides stock energy in the formation of covalent chemical bonds. Cells integrate such molecules and store them for the later discharge of the energy.

What is imunisition<br><br><br><br>please help me guys

VLD [36.1K]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2>

$\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}$

Active Immunity, Immunity which is acquired by the own immune response of the body.

Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

x---------------------------------------------------x

<h2> </h2><h2> $\Huge\text{Vaccination:}$ </h2>

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.
