 Which of the following best describes deflation as it relates to Earth science? A. Beach erosion caused by high tides
B. An avalanche caused by skiers
C. High tides caused by full moons
D. The lowering of land surface caused by wind

Answers

Answer 1
Answer: The lowering of land surface caused by wind best describes deflation as it relates to earth science. So for the given question, the right option will be option “D”. The word deflation can be used in a variety of ways. In case of finances, this is a commonly used term and is the opposite of inflation. In case using this word in relation to earth, it can be used to describe the erosion of loose materials by the force of wind from dry and flat areas like the deserts.



Answer 2
Answer: the answer is D.The lowering of land surface caused by wind
Deflation is wind activity which also causes rock erosion or transports sand and dirt.

Answers

The natural selection. 

Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. So genotypes variations are responsible for phenotypes and, thus, help the survival of species in a particular location.

Answers

The answer is skin.

There are four basic types of animal tissue - epithelium, connective, nervous, and muscle tissue. Epithelial cells form epithelium which covers surfaces of blood vessels and organs in the body. All glands are, as well, made of epithelial cells. Also, epithelial cells grow close together to form the body's skin. 

The organic chemicals that help cell membranes to conserve internal fluids are _____. a. hormones
b. phospholipids
c. amino acids
d. proteins

Answers

the most appropriate answer is B ! as it helps in maintaining isolated internal environment !!
The organic chemicals that help cell membranes to conserve internal fluids are the phospholipids. They are composed of fatty acid, glycerol, phosphate group and a polar molecule. The phosphate group and polar head region of the phospholipids is attracted to water while the fatty acid is repelled by water. They are a major component of the cell membrane in which it encloses the organelles of the cell. It also limits what enters and exits the cell because of its two heads.

Which statement about endotherms and ectotherms is correct?1. Endotherms are regulators while ectotherms are conformers
2. Endotherms have higher energetic demands compared to ectotherms.
3. Endotherms spend more energy on internal temperature regulation compared to ectotherms.
4. Endothermy is more common among animal phyla than ectothermy.
5. At the cellular level, endotherms cells always produce more ATP and more heat.

Answers

Answer:

3.  Endotherms spend more energy on internal temperature regulation compared to ectotherms.

Explanation:

Ectotherms, are considered  as cold-blooded animals (reptiles and amphibians),  and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.

Endotherms also called warm blooded animals  (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.

The purpose of the right ventricle is to: receive blood coming back from the lungs pump blood to the upper and lower body pump blood into the lungs to be oxygenated receive blood back from the upper and lower body

Answers

The right ventricle's function is to pump blood into the lungs so that it can be oxygenated. The correct option is C.

Thus, deoxygenated blood from the right atrium is taken up by the right ventricle and pumped into the pulmonary artery, which transports the blood to the lungs. Through the act of breathing, the blood obtains oxygen in the lungs and releases carbon dioxide.

The oxygenated blood is then returned to the left atrium of the heart where the left ventricle pumps it to the remainder of the body. As a result, the right ventricle's main job is to pump blood to the lungs where it may be oxygenated.

Thus, the ideal selection is option C.
