Answer:
C. Exocytosis uses transport vesicles to export materials from the cell
Explanation:
Exocytosis is the reverse process of endocytosis including the expulsion of the material that is membrane -encapsulated (material is packaged in the vesicles ) inside the cell out of the cell. It has following steps :
1) The cell forms a vesicle around a material which is to be expelled.
2) The vesicle is transported to the cell membrane.
3) The vesicle membrane fuses with the cell membrane and releases the contents from the cell.
Hence option C. Exocytosis uses transport vesicles to export materials from the cell IS THE RIGHT OPTION.
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
Answer:
The immune system protects the host from pathogenic organisms (bacteria, viruses, fungi, parasites). To deal with this array of threats, the immune system has evolved to include a myriad of specialised cell types, communicating molecules and functional responses.
