Answer:
AAA
Explanation:
B) Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an example of feedback inhibition.
C) What is feedback inhibition? How is the ATP generating pathway discussed in part B an example of feedback inhibition?
Answer: B)
B) ADP can act as an allosteric activator by slowing the breakdown of fuel molecules if sufficient energy is in the cell. APT can act as an inhibitor by storing resources in more complex molecules. That is an example of feedback inhibitor because when the end product of the substrate is finished, it can bind to the allosteric site, which will result in the enzymes active site no longer being able to bind with the new substrates. And that is responsible for ATP production because That “stops” the enzyme from making more than necessary and thus wasting chemical resources.
C) Feedback inhibition is a method of metabolic control in which the need of the product of a metabolic that way acts as an inhibitor of an enzyme within that pathway. The APT generating path is an example of feedback inhibition because it controls the amount needed of the product and acts as an inhibitor of the enzyme in the anabolic pathway.

In passive transport, molecules move__ the concentration gradient.
Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.

When two heterozygous parents are crossed (Aa x Aa), what percent of the offspring will have a dominant phenotype ?
The percent of the offspring will have a dominant phenotype is 25% or 1/4 when two heterozygous parents are crossed (Aa x Aa).
What is the percentage of a phenotype for a heterozygous genetic cross?The percentage of a phenotype for a heterozygous genetic cross is 25 percent because there are two types of gametes in the parent and the cross between one of them for each parent is 1/4.
Therefore, with this data, we can see that the percentage of a phenotype for a heterozygous genetic cross is equal to 25% due to the combination of gametes.

Explain how the structure of sperm cells is related to their function.
Please answer I will give brainliest to the first correct answer!
The structure of sperm cells as it relates to their function are:
The head: It helps carry the genetic information to the haploid nucleusThe acrosome: It helps the sperm enter the egg of the femaleThe middle piece: It is responsible for the release of energyThe tail: It helps the sperm to swimA sperm cell is the male sex cell which is responsible for reproduction as it fuses with the female gamete and forms a zygote through fertilization.
As a result of this, there are different processes which are required for fertilization to occur as the sperm cell has to move through the head and fertilize with the ovule to form a new cell, called zygote.

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario?
Answer:
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.

substitution - a base was changed
O insertion - a base was added
O deletion - a base was removed
Answer:
substitution - a base was changed
Explanation:
The nucleotide sequence CTT was changed to the sequence CAT. The T was substituted with an A. This changed the encoded amino acid from Glu to Val.
An insertion is where an additional base is added (e.g. if the sequence changed from CTT to CATT)
A deletion is when a base is lost (e.g. if the sequence changed from CTT to CT)
The image below is part of a computer-generated model representing covalently bonded nonmetal atoms arranged in a crystal lattice. Four small atoms are bonded to each large atom. The structure extends in every direction.
The covalent network solid represented by the model likely
A.
is hard and strong.
B.
has a low melting point.
C.
is an electrical conductor when in the molten state.
D.
is a good conductor of both heat and electricity.
Answer:
A: is hard and strong
Explanation:
The crystal lattice shown is that of silica, SiO2. For a single molecule of silica to form, the silicon atom would have to form double bonds with each oxygen. Instead, each atom of silicon forms a bond to four different oxygen atoms, each of which is bonded to another silicon atom. This forms a covalent network.
Covalent network solids have the following properties:
They are hard and strong.
They have high melting points.
They usually do not conduct heat.
Silicon dioxide is an electrical semi-conductor.
Hope this helped :)
The structure extends in every direction. The covalent network solid represented by the model likely is hard and strong. Thus option A is correct.

What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.Hence the correct option is B.

Predict Ground limestone can be added to soil to make it less acidic. Would you expect the pH of
limestone in a water solution to be less than or greater than 7?
Answer:
greater than
Explanation:
The pH of limestone in a water solution would be greater than 7.
pH is a measure of the degree of acidity or alkalinity of a solution. If we say that we want to make the ground soil less acidic, then we definitely have to add a basic substance.
A basic substance is one whose pH is greater than 7. The pH scale is organized in such a way that acids span from 0 - 6.9. A pH of 7 indicates neutral while a pH of 8 - 14 indicates a basic substance.
If limestone is basic, it must have a pH greater than 7.
