why does the sodium potassium pump require ATP?
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Explain the differences in the three types of RNA by connecting it to a factory.
[tex] {\huge{\sf{\green{\underline {\underline {Answer }}}}}} [/tex]
Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled .RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.HOPE IT HELPS YOU.....
Which of the following is not a stage in hurricane formation?
A)
Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.
B)
Pollution in the atmosphere raises the temperature of the air, creating a depression.
C)
Warm, moist air rises from the sea and increases the storm’s energy.
D)
As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.
E)
As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.
Answer:
B
Explanation:
Because if that was the case we would have hurricanes everyday
Why might it be hard to restore a wildlife population using custodial management?
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.
What is the process of evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations. According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.These characteristics are easily trasffered from one generation to other generation.
Therefore, The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.

Which of the following explains how fault is formed?
a. Earthquakes shake the rocks to slide horizontally, vertically, or sideward.
b. Gravity pulls on the crust to slide up, down or past each other.
c. Different forces pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
d. Same force pushing or pulling on the crust causes rocks to slide horizontally, vertically, or sideward.
Answer:
a. Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Explanation:
The correct answer is - a.Earthquakes shake the rocks to slide horizontally, vertically, or side-ward.
Reason -
A fault is a fracture or zone of fractures between two blocks of rock.
Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep.
During an earthquake, the rock on one side of the fault suddenly slips with respect to the other.
The fault surface can be horizontal or vertical or some arbitrary angle in between.
Which is correctly matched with the
appropriate number of chromosomes
in each daughter cell?
A Meiosis: 2 sets of 23 chromosomes
B. Meiosis: 1 set of 23 chromosomes
C. Mitosis: 1 set of 23 chromosomes
D. Mitosis: 2 sets of 46 chromosomes
The match for the appropriate number of chromosomes in each daughter cell is "Mitosis: 2 sets of 46 chromosomes". Option D. This is further explained below.
What is Mitosis?Generally, Mitosis is simply a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.
In conclusion, "Mitosis: 2 sets of 46 chromosomes" matches the appropriate number of chromosomes in each daughter cell.

Where do electrons go after they leave chlorophyll?
Answer:
They leave and find somewhere else to replace the previous electron that had left just like it did and repeats the same process over and over again.
Explanation:
This is what i found on the internet to further explain my response, "The electron lost from the chlorophyll a special pair is replenished by splitting water. The passing of the electron in the first part of the electron transport chain causes protons to be pumped from the stroma to the thylakoid lumen." "When light strikes chlorophyll (or an accessory pigment) within the chloroplast, it energizes electrons within that molecule. ... The excited electrons leave chlorophyll to participate in further reactions, leaving the chlorophyll “at a loss”; eventually they must be replaced."

How does size influence the appearance of a star? Give an example in your response.
Answer:
when the size of a star increases, luminosity of star also increases.
The color of a star is decided by the surface temperature of the star and the temperature of a star depends on the size of star.
The smaller stars have low temperature and they are usually red (Proxima Centauri - red dwarf star).
The massive stars have higher temperature and they are usually blue (for exaple Zeta Puppis - Blue supergiant star).
