Answer:
Ozone
Explanation:
Ozone is a molecule made up of three atoms of oxygen. It works a lot like sunscreen, blocking out harmful ultraviolet (UV) rays from the sun. In recent years, the amount of ozone in the atmosphere has decreased. So will the Earth, and all of the life on it, get sunburned?

Why are ion channels necessary to transport ions into or out of a cell?
Answer:
Ions carry electric charges and are not soluble in the lipid bilayer of the cell membrane.
Explanation:
I found it on google lol
Ions are too large molecules to diffuse through the cell membrane hence require some proteins to facilitate their transport. Ions channels helps in transporting the ions through the cell membrane and the flow of current through the membrane.
What are ion channels?
Ion channels are the type of transport proteins which are present in the cell membrane that facilitates the movement of ions through the membrane. Cell membrane is selectively permeable in nature and thus does not allow many molecules to transport through it.
Ion channels facilitates the passive movement of ions across the cell membrane and are essential for cell survival. Ion-channels helps in elucidating the structure-function mechanisms of the proteins present in the membrane. Ion channels help in creating ion gradient and moving charge through the membrane.

Explanation:
How do bacteria help plants grow?
They break down carbon dioxide into carbon and oxygen.
They protect plants from pollution from acid rain and hydrocarbons.
They change ammonia into nitrogen gas for plants to use to make proteins.
They change nitrogen into nitrates plants use to make proteins.
Answer:
They change nitrogen gas into nitrates for plants to make proteins.
Explanation:
Nitrifying bacteria and Nitrogen-fixing bacteria work together to convert nitrogen gas into nitrates which plants use to make DNA, RNA, and amino acids (which are used to make other proteins).
Bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.
How do bacteria help plant growth?Bacteria help to plant growth by helping nitrogen assimilation during different metabolic processes.
This nitrogen is fundamental to synthesizing proteins, which are mainly composed of this element.In conclusion, bacteria help to plant growth by changing nitrogen (N element) into nitrates plants use to make proteins.

endoplasmic reticulum (ER)
Answer:Endoplasmic Reticulum
The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway. Synthesis: Ribosomes that are attached to ER, similar to unattached ribosomes, make proteins. Lipids are also produced in the ER.

An enzyme called glucocerebrosidase breaks down a glycolipid in the body known as glucocerebroside. However, in a genetic disease known as Gaucher’s disease, the body does not produce enough glucocerebrosidase. Therefore glucocerebroside can build up in the body and this can cause serious side effects such as anemia and swelling of the liver and spleen. Identify the substrate.
Answer:
glucocerebroside
Explanation:
The substrate is the substance being acted upon by the enzyme. The enzyme glucocerebrosidase breaks down glucocerebroside. Therefore, glucocerebroside is the substrate in this example.
