Give a scenario where a cell may need to perform a form of endocytosis and exocytosis
Firdavs [7]
<span>A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules.
A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell. The movement of macromolecules of polysaccharides or proteins out of or into the cell is known as Bulk transport.
Bulk transport is of two types which include endocytosis and exocytosis whereby both require an expenditure of energy. Exocytosis materials are being exported out of the cell via secretory vesicles.
Golgi complex they do package macromolecules into transport vesicles which travel to and spill its content out of cells. Exocytosis is very much important in the expulsion of waste materials out of the cell and also in products secretion. Endocytosis is the process where materials move into the cell.
 Endocytosis is divided into the three types which include pinocytosis, phagocytosis, and receptor-mediated endocytosis.</span>

Liono4ka [1.6K]

Imagine that a eukaryotic cell carries a mutation that causes the poly(a) tail to rarely be added to the primary transcripts. The result of such a mutation will be the primary transcript would likely be less stable, and its transport from the nucleus to the cytoplasm would be affected.

A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

While most mutations are benign, some can be detrimental. A dangerous mutation may lead to a cancerous condition or possibly a genetic problem. Chromosome mutations are yet another type of mutation. The tiny, thread-like structures known as chromosomes, which are found in the cell nucleus, carry genes.

Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work. Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.

Correct answer looks like to me would be A. Because, if a sunflower has 34 chromosomes, when you split it up into x and y chromosomes, there will be 17 x chromosomes and 17 y chromosomes. Hope this helps!

A.

Because yellow is more dominant so it’s more common for offsprings to have yellow petals but some of the offsprings will also take some traits of the pink petals so it’s A!
