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.

A truck whose bed is 2.5 m long 1.5 m wide and 1.0 m high is delivering sand for sand sculpture competition. About how many trips must the truck make to deliver 7m of sand

Answers

Assuming you mean 7m^3 (meters cubed) of Sand:
Volume = base x width x height
The truck can hold a volume of 2.5 x 1.5 x 1 = 3.75 m^3.
To move 7 m^3 of sand, the truck will have the make two trips. The first trip, the truck will move 3.75 m^3 of sand, and on the second, it will move 7-3.75=3.25 m^3.

Low sample size can affect the results of a scientific experiment because it may notgive an accurate picture of what would occur in the natural world.

4- Option D

5- Option B

6- Option C

7- Option B

Explanation:

Constructive forces are the forces that add new landmass on earth. They are typically formed by events such as volcanic eruptions, sediment deposition, and distortion in the crust.

The Hawaiian volcanic islands were formed due to the subduction of the Pacific plate under the NorthAmerican plate.

A dome generally forms when the magma rises up towards the surface. This hot magma lifts the land area, and subsequently with time, the magma cools and solidifies before eruption, giving rise to the formation of domes.

Beaches are formed due to the continuous erosion of the coastal rocks by the sea waves. Waves also carry sediments from the oceans to the coastal beach but it mainly erodes the rocks and sediment particles that are present on the beach area.

When sediment particles are carried by the rivers and streams and are deposited at the mouth of the river, then a delta is formed.

When an oceanic plate collides with a continental plate, then the denser oceanic plate gets subducted beneath the continental plate and forms a region of subduction where at great depth partial melting of the subducting plate takes place.

Along the mid-oceanic ridge, new crusts are added because the hot magma comes out to the surface and solidifies. This are rocks that are basaltic in nature.
