Answer:

ATP

Explanation:

ATP is regarded as 'root of energetics' for living organisms. So, the organisms utilizes ATP to transport material and eliminate wastes from the body. Not only these functions are carried out by ATP but also several others infact all energy requiring processes are carried out ATP. e.g. muscle movements, neurotransmission, heart beats and various chemical reactions in the body all are carried out with the help of ATP.

In animals ATP is produced from the breakdown of glucose in the cellular respiration, glucose is obtained from the diet we take in. In plants ATP is generated from the process of photosynthesis. The source of energy within ATP is phosphate bonds, the breakdown of one phosphate bond while conversion of ATP into ADP produces or releases 30.6 KJ/mole of energy.

_________ cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membra
dlinn [17]
Well I'm not exactly certain where the teacher is going with this, but an often used example is red blood cells (RBCs) aka: erythrocytes.
RBCs are suspended in blood plasma as they flood through vessels around and around the body, so the osmolarity (amount of small particles that affect osmosis) must remain relatively constant. This is termed "isotonic", meaning the same amount of osmosis-influencing particles that are there inside the RBCs' cytosol, within their plasma membranes.
If the plasma osmolarity get too high, called hypertonic (as with extra salt particles) then water inside the RBCs will have an osmotic force driving it out of the cells' membranes, to flow where there are more salt particles. This will lead to cell shrinkage (called "crenation").
Counter to that, if the plasma osmolarity gets too low, as due to low plasma salt with excessive water intake (for example from the condition "water intoxication"), then the plasma will be hypotonic with respect to the intracellular cytosol concentration. This can result in water rushing into the RBCs' membranes via osmosis, causing the cells to swell from discs into spheres (balls), or even rupture and burst (a phenomenon called "hemolysis").

Which statements describe functions of antibodies? Select two options.
vodomira [7]

Answer:

This question lacks options, options are:

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

Why the rainforest in Costa Rica is not rich with plants? Remember to use scientific language
Troyanec [42]

Answer:

Deforestation is the major problem causing lack of rich species in Costa Rica. This is due to over grazing by cattle.This may lead to flooding which affect fertility of the soil.These animals graze on  the plants without regulations,and cause erosion as their hoofs percolate the soil,  further reducing soil fertility.

In addition to sustain the beef production,  trees were fell to for cattle ranching.This ultimately contributed to loss of the forest species.

Banana plantation is an  additional factor.Forest were cleared to cultivate banana, which affects forest population.
