Answer:

Materials get transported from the cell by some mechanisms such as Active Transport, Passive Transport, Diffusion, etc.

Explanation:

Active Transport :

It is a process by which, materials are transported from the extracellular membrane to the intracellular membrane with the help of ATP. It has a few types :  

Primary Active Transport :  

This system is standing upon the sodium-potassium pump. It moves out   Na⁺ from the cell and allows the entry of K⁺ into the cell. In this process ATP is a source of energy. E.g, Sodium-potassium pump.

Secondary Active Transport :

It is mainly standing upon Primary Active Transport. In this process, the main key point is the concentration gradient. There is already a concentration gradient set up by the primary active transport. This system uses that up and moves other substances against their own gradient concentration. E.g, assuming, there is a high concentration of sodium outside the cell,  if a route such as a channel or a carrier protein is open then sodium ions will move into the cell.  In this transport system, some cotransporters are used who move in the sodium ion into the sodium gradient.  

Passive transport :

It is a process by which, substances cross the plasma membrane without acquiring any energy from the cell. Here, no energy is needed because the substances are moving from higher concentration to its lower concentration. E.g, cell membrane or plasma membrane works as a permeable or semipermeable membrane.  

Diffusion :

It is the movement of a substance across a membrane, due to the concentration gradient, without any help from other molecules. E.g, movement of the gaseous molecule from cell to cell.

The genes that masks the effects of other genes
kicyunya [14]

epistatic gene

Explanation:

Some genes mask the expression of other genes just as a fully dominant allele masks the expression of its recessive counterpart. A gene that masks the phenotypic effect of another gene is called an epistatic gene; the gene it subordinates is the hypostatic gene.

What is the relationship among solutions, solutes, and solvents?
valentinak56 [21]
Solvents are dissolved in a solute to create a solution. Some examples are sugar solutions, where sugar is the solvent, water is the solute, and the solution is the sugar water that results, as long as the sugar is dissolved evenly in the water.

How do microorganisms eliminate harmful material
djverab [1.8K]

Answer:

Microorganisms are very small, not visible with an eye, including bacteria, viruses, fungi, and parasites.

Even though som of microorganisms can make people ill, many of them are not harmful, all the contrary, they can help a human with digestion, protect him from infections and keep the health good.

Explanation:

You have bad microorganisms in the body, called pathogens. Pathogens can be very harmful and kill all the good cells in the host. That is why good microorganisms are important. They make colonies and protect the body from the development of pathogens that release toxins into the body.

Good microorganisms provide nutrition for the organism, they involve minerals, produce hormones and stop bad microorganisms enter the organism.

Why are carbon atoms so common in living things? Include the term carbon skeleton in your answer.
aliya0001 [1]
The main reason why carbon atoms are so common in living things is because carbon is a very adaptable element in the sense that its electron configuration allows it to bond with many other atoms.
