Which two life functions of animals help maintain the water cycle by recycling water back into the environment a.) digestion and regulation
b.)synthesis and locomotion
c.)respiration and excretion
d.)reproduction and growth

Answers

Answer:

The correct answer would be c.)respiration and excretion.

Excretion refers to the removal of harmful substance or wastes out of the body.

The excretory system helps in removing nitrogenous waste and excess water out of the body.

Skin also helps in excretion of water, salts, and some nitrogenous wastes through sweating.

Respiration not only helps in taking in the oxygen but also help in removing carbon dioxide and water vapors out of the body.

The excreted water then can re-enter the environment by different means such as by evaporation (it enters atmosphere), by mixing (drainage system) with large water bodies such as river or seas, as underground water, or absorbed by plants.

Thus respiration and excretion help in maintaining the water cycle by recycling water into the environment.
the answer has to be c

1.       Cell membrane – mostly in animal cells, the protective layer in every cell
2.       Endoplasmic Reticulum – plays a role in synthesis and production of lipid and protein
3.       Ribosome – These organelles gather and use RNA to synthesize and produce polypeptides and protein
4.       Golgi Apparatus – serves as a courier that packages, modifies and sorts proteins and other materials that it receives from the endoplasmic reticulum
5.       Lysosome – acts a digestive system in cells, it metabolizes and breaks down wasted organelles or materials in the cell
6.       Microtubule – serves as a framework of the cell –cytoskeleton.
7.       Mitochondria – acts as the powerhouse of the cell that uses ATP and converts it to energy
8.       Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell

Answers

Plants need carbon-dioxide and water and both of those are released into the air by respiration and during respiration, the plants need oxygen and glucose, which are produced by photosynthesis. hope that gave a clue... 

Which processes form metamorphic rocks?A.
melting and pressure

B.
pressure and cooling

C.
melting and cooling

D.
heat and pressure

Answers

When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions, metamorphic rocks are created, hence option D is correct.

What are metamorphic rocks?

The process of metamorphism, which changes one type of rock into another, produces metamorphic rocks.

Rocks can become metamorphic when they are exposed to intense heat, high pressure, hot mineral-rich fluids, or, more frequently, a combination of these elements.

In spite of having undergone significant changes from their initial igneous, sedimentary, or early metamorphic forms, metamorphic rocks began as another kind of rock.

Therefore, metamorphic rocks formed when rocks are treated with the high heat and high pressure, hence option D is correct.
