To determine the reason for the fish death, do the following:
1. Test the water for the presence of organic substances that may be poisonous to the fish.
2. Test the dissolved oxygen concentration of the lake at different locations and at different depths. 
3. Perform full toxicological examination of the lake to determine if any pollutant or poisonous chemical is present in the lake.<span />

aksik [14]

According to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.

What is exocytosis?

It is the expulsion, by cells, of particles that, due to their size, cannot pass through the cell membrane.

In this sense, it is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted. Insulin is released to the outside by exocytosis, intervening in the process of glucose entry into cells.

Therefore, we can conclude that according to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.

Kyle concludes that the cell must be a plant cell. How does Kyle know that the cell is a plant cell and not an animal cell?
Mnenie [13.5K]

Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.

There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...

The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't.  Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.

Thankyou.

Sorry for my bad english, It's not my native language.
