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

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.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production
natima [27]

Answer:

This question lacks options, the options are:

a) Negative primary production

b) Net primary production

c) Secondary production

d) Negative secondary production

e) Positive primary production

The correct answer is b.

The total amount of chemical energy produced by autotrophs, such as plants and phytoplankton, is called gross primary production. The energy that remains after plants use some of the gross primary production to fuel their own metabolism is known as <u>net primary production</u>.

Explanation:

Net Primary Production (NPP) is the value that results from the difference between gross production and respiration of the primary producers themselves. It manifests as growth and / or reproduction. It represents the matter and energy available for the next trophic level, that is, the net primary production is what is left after subtracting the energy that plants use for their metabolism or maintenance (such as breathing, tissue construction and reproduction).

A molecule of messenger RNA (mRNA) has just been synthesized in the nucleus of a human cell.
Murljashka [212]

The mRNA will attach to the small ribosomal unit and then the large ribosomal unit. Then the mRNA will be decoded with its codon's tRNA. ... The tRNA will come in at the A site and a peptide bond will form between amino acids at the A and P sites.
