The body performs many processes that depend upon energy and could not occur without a supply of ATP. ATP powers cellular reactions by y transferring a phosphate group to another molecule in a process known as phosphorylation.
ATP also known as adenosine triphosphate is a molecule that is found in the cells of living organisms. ATP releases energy to start the different cellular processes. It itself stores energy from the breakdown of food.
It does not exactly store the energy but acts as a way of transport to deliver energy where it is required within the cell. It also provides energy to those reactions which release energy but need a little to proceed.

One reason cells divide is that
One reason cells divide is that Growth and Replacing damaged or dead cells.
For your body to expand and for bodily tissue like skin to continuously regenerate itself, cells must divide. When a cell splits, the outer membrane pulls inward more and more until the newly developing cells separate from one another. Usually, this procedure divides the original (parent) cell into two new (daughter) cells. Because food and oxygen must be transported to the internal components through the cell membrane, cells are constrained in size A cell's outer cannot keep up with its interior as it expands because the interior expands more quickly than the exterior.learn more about cells divide here: https://brainly.com/question/796780

Anabolic hormone is the one that is involved in the formation of some specific substance inside the body. Thus can include repair of damaged tissues or growth of muscles as well. The examples of anabolic hormones are: insulin, growth hormones, testosterone, etc.
Insulin is the sugar regulatory hormone made up of polypeptide chains. It is called an anabolic hormone because it promotes the uptake of glucose by the cells in order to reduce the blood glucose levels. This promotes the formation of glucagon (a stored form of energy) that can result in increase muscle mass.

When the cell enters prophase, DNA replication has already started after interphase. The chromatin reticulum condenses and the nucleolus vanishes during prophase, which are the key events. The chromatin, a combination of DNA and proteins found in the nucleus, condenses during prophase. The development of discernible chromosomes is caused by the coiling and tightening of the chromatin.

Which box represents a carbon sink that holds carbon compounds for the shortest period of time?
A
B
C
D
Answer:
A
Explanation:
A box represents a carbon sink that holds carbon compounds for the shortest period of time. So, the correct option is A.
What is Carbon sink?A carbon sink is defined as a natural or otherwise that accumulates and stores some carbon- containing chemical compound indefinitely and thereby removes carbon dioxide from the atmosphere. The two most important carbon sinks are vegetation and the ocean where soil is an important carbon storage medium.
A carbon sink is describe as something which absorbs more carbon from the atmosphere than it releases – for example, plants, the ocean and soil. Carbon dioxide can move to plants to be stored as glucose much more rapidly than in sedimentary rocks and fossil fuels where carbon compounds are most likely to be retained for the shortest time in vegetation.
Thus, A box represents a carbon sink that holds carbon compounds for the shortest period of time. So, the correct option is A.

The membrane is composed of phospholipids that will form a lipid bilayer through which products pass through it.
How is the plasma membrane composed?The plasma membrane is made up, among other components, of phospholipids that will generate a phospholipid bilayer due to its amphipathic nature. Due to its conformation, different molecules will not find it easy to pass through the plasmatic membrane into and out of the cell, for this reason, the cell will have types of transport to be able to allow the passage of substances.
Within these forms of transport, we find endocytosis, which is when the cell enters bulky materials inside the cell, exocytosis, which is when it takes bulky materials out of the cell, is the facilitated diffusion by which molecules pass without spending energy thanks to its concentration gradient and active transport in which the channels need ATP to be able to pass the molecules through it since it is done against its concentration gradient.
Therefore, we can confirm that the membrane is composed of phospholipids that will form a lipid bilayer through which products pass through it.

firearm sold for $500 and the Pittman-Robertson Act collected an 11-percent excise tax. How much money was raised for conservation from the sale of firearms during 2020? Be sure to show your work.
50 points
The amount of money that was raised for conservation from the sale of firearms is = $8,455,000,000
Calculation of total cost of firearmsThe number if firearms sold in U.S. during 2020= 19,000,000
The cost of an average firearm = $500
The tax collected per firearm by Pittman-Robertson Act = 11%.
That is, 11% of $500
= 11×500/100
= $55 for every firearm
The total cost of 19million firearms
= 19,000,000 × 500
= 9,500,000,000
The total tax collected form 19 million firearms,
= 55 × 19,000,000
= 1,045,000,000

#SPJ1
Answer:
To calculate the amount of money raised for conservation from the sale of firearms during 2020, we'll follow these steps:
Step 1: Calculate the total revenue generated from firearm sales.
Total revenue = Number of firearms sold * Price per firearm
Total revenue = 19,000,000 * $500
Total revenue = $9,500,000,000
Step 2: Calculate the amount of excise tax collected.
Excise tax = Total revenue * Excise tax rate
Excise tax = $9,500,000,000 * 0.11
Excise tax = $1,045,000,000
Therefore, the amount of money raised for conservation from the sale of firearms during 2020, based on the given information, is $1,045,000,000.
