Answer:
Option-C
Explanation:
Delta G (△G) refers to the overall energy released during a chemical reaction when equilibrium is reached i.e the rate of conversion of product into the substrate is equal to the rate of conversion of substrate into product. Thus, △G accounts for the equilibrium of the reaction.
In the given question, it has been mentioned that △G of a reaction is -20 kcal/mol then how will it change if the amount of enzyme is doubled.
The △G is not affected by the enzyme concentration as the presence of enzyme affects the G (Gibbs free energy) and activation energy.
Therefore, △G will remain the same even if the amount of enzyme is doubled i.e -20 kcal/mol will be the correct value.
Thus, Option-C is the correct answer.
The cell membrane is made up of a lipid bilayer as shown in the model. Which of the following describes the structure and function of the cell membrane?
56 points!!!!!!
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.

Which best describes the relationship between DNA, genes, and chromosomes?
DNA are segments of genes that form tight coils called chromosomes.
Genes are segments of DNA that form tight coils called chromosomes.
Chromosomes are segments of DNA that form tight coils called genes.
Genes are segments of chromosomes that form tight coils called DNA.
Answer:
genes are segments of chromosomes that form tight coils called dna
The statement that best describes the relationship between DNA, genes, and chromosomes is as follows:
Genes are segments of chromosomes that form tight coils called DNA.Thus, the correct option is D.
What is Chromosome?A Chromosome may be defined as a thin thread-like structure that appears during the process of cell division. Such types of thread-like structures are significantly present in the nucleus of the cell.
Chromosomes are made up of DNA, RNA, histones, and some non-histone proteins. Chromosomes were first discovered by E. Strausburger in 1875.
Genes are small stretches that significantly considered the segments of chromosomes. Together they form a tightly coiled structure remarkably known as DNA. Genes carry nucleotide sequences that can produce functional enzymes or proteins.
All such parts carry genetic information with respect to the existence of organisms on the basis of morphology and function.
Therefore, the correct option for this question is D.

Do all plants respond the same to all abiotic factors?
Answer:
Light intensity: limited light will limit photosynthesis. This will affect the distribution of plants, and therefore the distribution of animals that eat plants. ... Temperature: temperature is a limiting factor for photosynthesis - and low temperature therefore limits growth of plants.
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.
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.learn about nitrogenous waste,

What is a convection current?
a current in a fluid that results from convection.
What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?
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 muscle cells are often considered as 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
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
