In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.
Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.
This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
Where in a cell does this transport process take place?
A.
nucleus
B.
cell wall
C.
cell membrane
D.
vesicle
The Transport process takes place in cell membrane.
What is Transport?Cell transport describes the transportation of a material across a cell membrane. The chemical has the ability to enter or exit cells.
The plasma membrane and cell membrane are both permeable to different substances. The nature of the plasma membrane is quite selective.
Cell transport is very important for transport of molecules. There are two transport of cell transport of endocytosis and exocytosis.
Therefore, The Transport process takes place in cell membrane.

Differentiate betweeli population density and
population distribution.
Answer:
The main difference between population density and population distribution is that the population density is the number of individuals per unit land whereas the population distribution is the spreading of people over an area of land. Furthermore, population density is unable to describe where the population actually lives, unlike population distribution.
Population density and population distribution are two measurements of population used in a variety of applications in ecology.

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.
Hope it helps! :)
Have you ever wondered how we can grow from one cell to millions? How do you think this happens?
Answer:
If you think about it, the fact that a single cell can grow into an adult with trillions of cells is pretty awesome. ... It's a process called the cell cycle. Entire organisms grow, and develop by going through the cell cycle again and again. The cell cycle also helps us maintain a healthy body.
From a single cell to multiple cellular organism is formed by different complex mechanism like by cell division which involves a central dogma of life includes three process such as replication, transcription and translation and fourth one is reverse transcription.
what is central dogma ?The ‘Central Dogma’ is the flow of transfer of genetic information, from DNA to RNA to make a functional product, a protein, was first proposed in 1958 by Francis Crick.
DNA contains the genetic information needed to make proteins, and RNA act as a messenger that carries this information to the ribosomes where the information is translated into protein.
The process by which the DNA information converted into protein called gene expression which can occur in two stages like transcription and translation.
The central dogma occurs most frequently in our cells in three stages such as DNA replication that refers to make new DNA from pre existing DNA, transcription to make RNA from DNA and translation from RNA to protein.
Reverse transcription is defined as the transfer of information from RNA to make new DNA in a reverse manner which occur mainly in retroviruses, such as HIV.

feel the inside of your elbow as you lift a book. you should feel a strong cord. what is this? what does it do?
We feel the inside of the elbow as we lift a book. We should feel a strong cord. This cord is known as Oblique cord.
What is the Oblique cord?The oblique cord is a ligament which is present between the ulnar and radius bones in the forearm region near the elbow. Oblique cord takes the form of a small, flattened band, which is extending downward and lateralward, from the lateral side of the ulnar bone tuberosity at the base of the coronoid process to the radius of a little below the radial tuberosity. The fibers in this cord runs in the opposite direction to those of the Interosseous membrane of the forearm region of the hand.
The oblique cord may simply be defined as an additional tie which is between the radius and ulna of the hand which is aiding other soft tissue structures such as the annular ligament and interosseous membrane. Additionally, the oblique cord may also prevent the anterior shearing of the proximal radius under the extreme compressive loads.

What is meant by a phenotype ratio in a Punnett square? (1 point)
A. the fraction of possible offspring that can be observed to have a trait
B. the number of genes that are possible in offspring
C. the number of alleles in possible offspring
D. the fraction of possible offspring that contain a certain allele in their genes
Given the nature of a punnet square, we can conclude that the ratio in question refers to the combination of genotypes present in the square.
A punnet square is a diagram used to attempt to predict the genetic composition for the offspring of certain parents, that is the genotype for this specific cross. This is done by creating a square in the form of a grid and placing the genotypes of the parents on the outside of this then crossing them along the inside.
This diagram provides us with the probability of each genotype outcome. This is known as the phenotype ratio. The phenotypic ratio is the amount of times a specific outcome, such as a certain pair of alleles appears in the predicted genotypes of any of the offspring pertaining to this cross.
