What occurs when molecules move into a cell by fusing with the membrane

1 answer:

3 0

Facilitated Diffusion is a process for molecules that cannot be readily diffused through cell membranes. Such molecules may be too large to pass through the pores in the membrane. The movement of these kinds of molecules across the cell membrane is assisted by proteins known as Carrier proteins.

Sertoli cells are stimulated by ________, while leydig cells are stimulated by ________.

Lena [83]

Sertoli cells are stimulated by <u>FSH</u>, while leydig cells are stimulated by<u> LH.</u>

<h3>Sertoli and Leydig Cells:</h3>

The creation of T is stimulated by LH in Leydig cells, while the production of regulatory molecules and the nutrients required for maintaining spermatogenesis are stimulated by FSH in Sertoli cells in concert with T. As a result, Sertoli cells indirectly control spermatogenesis via T and FSH.

The growth and maintenance of the male reproductive system and spermatogenesis depend on LH-stimulated Leydig cell androgen synthesis. The interstitial cells of Leydig, which are concentrated heavily in the testis of newborn boys and adult males following puberty, release testosterone. Interstitial cells are another name for Leydig cells. The interstitial spaces outside of seminiferous tubules are where they can be found.

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different

KIM [24]

Answer:

The answer is 214.

Explanation:

This is because 130 base pair is adjacent to 14 base pair repeat , and you have 6 repeats. So 14 multiplied by 6 repeats is 84. If you add this to your primer amplicon, you will get the size of final PCR product i.e.. 214.

With human population of over 7 billon , we must protect endangered species habitat by not developing on them for any reason. Ar

Levart [38]

Answer:

As the human population rises, more and more forests and other habitats of animals are being destroyed to make room for the increasing population of humans. Such activities has led to the extinction of many species as their habitats are being destroyed completely. Some of the plant and animal species are at the verge of extinction because their habitats have been destroyed.

Humans should help increase the population of the endangered species by making habitats for them. For example, Salmon fish is one of the most consumed fishes by humans. Nowadays, some of the countries have artificially made aquacultures to raise these fishes before they become endangered or extinct.
