Explanation:
The grass population would decrease. The snake population and hawk population would increase.
The correct answer is option C. . If you were to suddenly double the population of rabbits, the grass population would decrease due to overgrazing by the increased rabbit population.
What will happen in result to it ?As a result, the snake population and hawk population would increase due to the increased availability of prey. This is known as a trophic cascade, where changes in one trophic level affect the populations of other trophic levels in the food chain.
Option A and B are unlikely as doubling the population of rabbits would not necessarily cause the populations of the other three species to increase or decrease in a straightforward manner.
Option D is incorrect as there is no direct relationship between the rabbit population and the hawk population in this food chain.

The term that describes when an enzyme loses shape and function.
Answer:
Denature
Explanation:
Denature
Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.
Active sites and substrate specificity
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.
In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens
This center part is not present in everyone's hair or may be broken into segments.

a typical eukaryotic cell has enough available atp to meet its needs for about 30 seconds. what is likely to happen to an individual when they exhaust their atp supply?
Eukaryotic cells rely on the molecular energy of ATP to sustain all of the reactions necessary to maintain life, in the absence of ATP, these reactions would come to a halt, and the cell would inevitably die.
ATP is a molecular compound that provides the energy needed by most cells to survive. ATP represents Adenosine triphosphate, which is an organic compound that provides energy to drive the essential metabolic reactions of living cells, such as:
Muscle contractionsNerve impulsesChemical synthesisNutrient absorbtionIn the situation in which a cell was to run out of ATP, these reactions would stop, given that they require ATP to function. This means that the cell would not be able to send or receive nerve signals, absorb the nutrients it needs, or even create necessary compounds such as proteins. The stoppage of these functions would lead to the death of the cell.

why are they assuming the large molecules will stay on their own side of the membrane?
Answer:
What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.
Explanation:
Hope It Helps
It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.
The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.
The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

Discuss the unique properties of water. (Polar, Hydrogen bonds, Cohesion, Adhesion)
Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.
Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.
Answer & Explanation:
The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.
Water molecules attract or are attracted to other polar molecules.
Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.
Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.
Cohesion holds hydrogen bonds together to create surface tension on water.
Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.
Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.
Key Terms:
hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules
cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules
hydrophilic: having an affinity for water; able to absorb, or be wetted by water
hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water
polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.
