So I have an assignment I need to do and I have no idea how to answer these questions, it is due by the end of the day. Even if

you don't understand some of these questions(I don't either) please try and post some answers. Thank You so much in advance.
PassiveCellular Transport (high to low concentration)

▪Diffusion –when, why & how does it occur?
▪Osmosis –when, why & how does it occur?
▪Facilitated diffusion –when, why & how does it occur?

Active Cellular Transport (low to high concentration)

▪Active transport –when, why & how does it occur?
▪Endocytosis –when, why & how does it occur? (phagocytosis vs. pinocytosis)
▪Exocytosis –when, why & how does it occur?

Membranes

▪structure & function
▪function of pores & carrier proteins

Answer:

1 - Diffusion is when small, non-polar molecules pass through the cell membrane. It happens so that the cell can get vital nutrients, it is a type of passive transport.

2 - Osmosis is the transport of water through the cell membrane. It is a type of passive transport, the water moves to the side of the cell with less water.

3 - Facilitated diffusion is when protein channels or transports help large polar molecules like glucose that ordinarily couldn't get through the cell membrane pass through the membrane.

4 - Active transport is when a molecule requires energy, ATP, to pass through the cell membrane. An example of this is molecular pumps, the use energy, ATP, to work.

5 - Endocytosis is when a vesicle captures an outside substance for the cell. There are two types of endocytosis, phagocytosis, which is "cell eating" where the cell digests solids, the there's pinocytosis, which is "cell drinking" where the cell digests liquids.

6 - Exocytosis is when a vesicle removes a substance from the cell by combining with the cell membrane and pushing it out.

7 - The Membrane is made out of phospholipids

8 - Carrier proteins help molecules that are large and polar get into the cell.

Sholpan [36]

Answer:

The original water sample contains 830,000 cells per milliliter.

Explanation:

A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.

Animal cells contain all of the following structures EXCEPT a A) nucleus. B) cell wall. C) mitochondria. D) Golgi apparatus.
tankabanditka [31]
<span>The answer is B) cell wall. The cell wall is a structure important cell protection and shape. It is necessary for the survival of unicellular organisms, such as Archaea and bacteria. Plants, some fungi, and algae also have cell walls with major function in structural support and protection against environmental conditions and infection. However, animal cells do not have cell walls.</span>
