Answer: covering crops
Explanation:
such as vetch, rye and clover, are excellent plants for erosion control. These hardy easy to grow plants send out nets of roots that help hold topsoil in place while also reducing competitive weeds. When tilled back into the soil, they increase the nutrient density as they compost.
The reason animals need a continuous supply of oxygen is to<u> Obtain energy from their food.</u>
<u></u>
The most fundamental reason why animals need a non-stop delivery of oxygen is without it animals can't achieve sufficient power from their meals.
Cells require a steady delivery of power to generate and preserve the biological order that keeps them alive. This electricity is derived from the chemical bond energy in food molecules, which thereby function as fuel for cells.
The animal's metabolism converts oxygen into strength. All through this system, a waste gas called carbon dioxide is produced. To remove it, the carbon dioxide is carried lower back to the lungs, where its miles are collected and exhaled.

Enzymes can be divided into two groups, intracellular and extracellular enzymes.
Enzymes formed and retained in the cell are known as intracellular enzymes. They are found in the cytoplasm, organelles and the nucleus of the cell. Examples of such enzymes are DNA polymerase, RNA polymerase and ATP synthetase.
Extracellular enzymes are produced in the cell then packed and secreted from the cell. This kind of enzymes catalyze reactions outside the cell. Most digestive enzymes are extracellular enzymes . Examples of such are amylase, zymase and cellulase
Answer: <span>3′; 5′ to 3′
</span><span>A new nucleotide can only be added to the 3' end of a growing dna strand. dna therefore always grows in the 5' to 3' direction.
3' means 3' hydroxil groups that is free before synthesis can be initiated.
5' to 3' means that DNA is always synthesized in the 5' to 3' direction.</span>
