Nitrogen from animal wastes or plant an animal tissue
O must be fixed near leguminous plants,
O is lost from the system.
O is fixed by bacteria and fungi in the soil.
O is already fixed and can be used.

Answers

System is okay better

Nitrogen from animal wastes or plant an animal tissue  is fixed by bacteria and fungi in the soil.

So, option C is correct one.

How plants and animals get nitrogen ?Since our atmosphere contains 78% of nitrogen but it is very difficult  to take directly by plants and animals.Nitrogen is very essential for all living organism.Plants take nitrogen from soil.Some bacteria and fungi are present in the soil who fix nitrogen from the atmosphere and convert it into nitrogen compound.Then this nitrogen from the soil by root system of the plants.Now plant use this nitrogen for synthesis of proteins and other compounds.Animals who feed plants gets this proteins and other nitrogen compound from plants.When plants and animals die , fungi and bacteria present in the soil converts this nitrogenous waste into nitrogenous compound and reuse of nitrogenous compound is repeated again.

What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?​

Answers

The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state. The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle. This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle; some cell types (such as neurons and heart muscle cells) when they reach maturity (that is, when they are terminally differentiated) become post-mitotic (enter the G0 phase), and perform their main functions for the rest of the life of the organism. Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.

Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle.

Mitosis is the procedure with the aid of which a mobile replicates its chromosomes after which segregates them, producing two identical nuclei in training for mobile division. Mitosis is generally followed by way of same department of the mobile's content material into  daughter cells that have identical genomes.

The two phases of cell cycle are interphase in which DNA replication occurs, 3 stages of interphase are: G1 phase, S phase and G2 phase and mitotic in which division occurs phase. Mitosis occurs after the completion of DNA replication and doubling of chromosome number and cell contents and after mitosis, two daughter cells are produced of equal number of chromosomes.

Therefore, The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.

which statement describes what happens with ATP during glycolysis?

A) more ATP is produced than is used

B) glycolysis splits ATP

C) more ATP is used than is produced

D) glycolysis does not make any ATP

Answers

Answer:

A. more ATP is produced than used

Explanation:

Regulation of glycolysis

Several steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK). This reaction is the first committed step, making PFK a central target for regulation of the glycolysis pathway as a whole^1  

1

start superscript, 1, end superscript.

PFK is regulated by ATP, an ADP derivative called AMP, and citrate, as well as some other molecules we won't discuss here.

ATP. ATP is a negative regulator of PFK, which makes sense: if there is already plenty of ATP in the cell, glycolysis does not need to make more.

AMP. Adenosine monophosphate (AMP) is a positive regulator of PFK. When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP \rightarrow→right arrow ATP + AMP). High levels of AMP mean that the cell is starved for energy, and that glycolysis must run quickly to replenish ATP^2

56 points!!!!!!

Answers

Answer:

The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell

Explanation:

Cell membrane is selectively permeable in nature. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment and hydrophobic tails form an oily layer inside the membrane. Thus, correct option is A.

What is Plasma Membrane?

Plasma membrane is also known as the cell membrane. It is found in all types of cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is also found which covers the cell membrane.

The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. Plasma membrane is selectively permeable in nature, it allows only some material to pass through it while blocks other material from entering through it.

The portions of the integral membrane protein found inside membrane are hydrophobic, while portions which are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic in nature. Molecules that are hydrophobic can easily pass through the plasma membrane while hydrophilic particles cannot pass through the membrane easily.

Therefore, correct option is A.
