Why are endocytosis and exocytosis kinds of active transport?​

Biology
2 answers:
Karo-lina-s [1.5K]3 years ago
7 0

Explanation: During endocytosis (endo means inside) a cell will use its cell membrane to engulf an object which is outside of the cell. This process takes effort by the cell, so it needs to use energy (ATP!) The process which is the reverse of endocytosis is exocytosis (exo means outside - think exit).

Answer:

Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane.

The distance between two charges and is r, and the force between them is F. What is the force between them if the distance betwe
dimulka [17.4K]

The force between them if the distance between them is doubled is a. F/4

Explanation:

  • To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
  • The equation can be written as, F= K \frac{ q_{1} q_{2} }{r^{2} } where k is the Coulomb constant, q_{1}  q_{2} are the point charges, and r is the distance between these two point charges.
  • To find the answer to this question, just substitute 2r in the place of r hence, you will get \frac{F}{4} as the new force when the distance is doubled.

Advances in biotechnology have made it possible for scientists to synthesize human insulin.
Alexeev081 [22]

Answer: a. True

Explanation:

Artificial human insulin is the advancement of the field of biotechnology. It is the product of recombinant DNA technology. The insulin is a hormone which is secreted by the pancreas to maintain the levels of sugar in the blood. But in some people the secretion of insulin can be found to be low or no insulin is produced at all these are affected by the condition called as diabetes. Thus artificial or synthetic insulin was invented to regulate the blood sugar levels. The artificial insulin is produced in the microbes like yeast and bacteria. The human gene encoding for the production of insulin is inserted into the microbial genome which produces the insulin in the microbial structure.

Which physical factors MOST influence a marine biome?
alina1380 [7]
The correct option is C.
The marine biome is the largest biome in the world and is made up of five different oceans. The marine biome is always affected by changes in the wave motion of water, salinity and the atmospheric pressure. The changes can either affect the organisms living in the biome either negatively or positively depending on the direction and the intensities of these changes.

What is the biological significance of genetic diversity between populations?
Nezavi [6.7K]

The answer to the above question is Genes for traits conferring an advantage to local conditions are unlikely.

<h3>What is genetic diversity?</h3>

Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition. It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity. It differs from genetic variability, which is the propensity for hereditary traits to change.

The ability of populations to adapt to changing circumstances is facilitated by genetic variety. More variation increases the likelihood that certain members of a group will have allele variants that are appropriate for the environment. Those people have a higher chance of living long enough to have children who carry that allele. The success of these people will allow the population to continue for longer generations.

The name given to media which allow different types of microbes to grow but are designed to display visible morphological or che
saveliy_v [14]

Given what we know, we can confirm that the type of media which allows the growth of different microbes while still being able to distinguish between them is called a differential media.

<h3>What is a differential media?</h3>
  • It is a type of media that allows for the growth of many different microbe types.
  • This media is special in that it allows the user to still distinguish between the microbes.
  • This is done primarily on a basis of the biochemical differences between the microbes.

Therefore, we can confirm that a differential media is a type of media that allows the growth of different microbes while still being able to distinguish between them, focusing on biochemical differences of the two colonies grown.
