Exocytosis occurred, where a vesicle or liposome is transported through the cell's cytoskeleton to the cell surface membrane to fuse with it, releasing the contents from within the vesicle and into the extracellular environment.
It does not matter if the vesicle or liposome had previously fused with a lysosome previously.
So long as it is a vesicle/liposome, which has a phospholipid bilayer membrane (I.e. the same as the cell surface membrane), and fusion occurs, it is exocytosis.

Hope this helps! :)

What is the purpose of meiosis? How does the cell do the following: reduce the chromosome number in half and create genetically
s2008m [1.1K]

Answer:

2 cells meet and the number of chromosomes becomes equivalent to the somatic cell.

Explanation:

In meiosis crossing over occurs and the number of chromosomes divided or remain half as compared to a somatic cell which is called Haploid (n). When two haploid cell meets than diploid (2n) cell formed which further transforms into a zygote. So, the purpose of meiosis is the cross over which creates genetic variation among individuals and reduced the number of chromosomes into the half. Because if the number of chromosomes remains the same as (2n) and (2n) meets and becomes 4n. Which is the wrong pattern so nature keeps this balance in a unique manner that (n) and (n) meets and form (2n).

Alik [6]

Answer:

the correct answer is D

Explanation:

In the germinal stage it is said that it lasts between 10 days and two weeks. During this stage, the fertilized egg divides and advances through the fallopian tube until it implants in the wall of the uterus.

If it cannot be implanted in the wall of the uterus, then it is considered a miscarriage due to the pregnancy, it cannot be carried out and it is very rarely perceived by the woman that the presence of the fertilized cell is imperceptible in bleeding.
