The correct answer is d. all of the above.

About 29 % of the solar energy is reflected back to space by clouds, particles in the atmosphere and by snow or sea ice and about 23 % of solar energy is absorbed by dust, water vapor and ozone present in the atmosphere. Only 48 % of solar energy passes through the atmosphere and is absorbed by the surface. Thus, approximately 71 % of the total solar energy is absorbed by the Earth system.

The answer is: D. all of the above.

When Earth receives energy from the Sun, some energy is reflected back into space, some is absorbed by the atmosphere, and some is absorbed by land and water on Earth's surface.

<h3>What is called Parenchyma?</h3>

The term "parenchyma" refers to the tissues that are employed for function in both plants and animals. Unlike "structural" tissues like wood in plants or bone in animals, this tissue is "functional," carrying out activities like photosynthesis in plants or information stored in the human brain.

A specific kind of ground tissue with thin cell walls and the capacity to expand and divide is referred to as parenchyma in plants. The majority of the cells in leaves, flowers, and fruits are parenchyma. In these formations, "structural" rather than "parenchymal" tissue makes up the hard, structural elements including bark, outer coatings, and major veins.

2. An adaptive advantage of having a three-chambered heart, as found in amphibians, over the two-chambered heart of fish is that

Nadya [2.5K]

Answer:

fully oxygenated blood returning to the amphibian heart can undergo additional pumping to reach higher pressures.

Explanation:

Fishes have a two-chambered heart with one atrium and one ventricle. The blood is pumped from the atrium into the ventricle. Ventricle pumps blood into a single circuit of blood vessels. Blood is oxygenated as it passes through capillaries in the gills. As blood circulates through the gill capillaries, it has low blood pressure and therefore, is delivered very slowly to the other organs.

The amphibian heart has two atria and one ventricle. A sinus venosus collects oxygen-poor blood and pumps it into the right atrium. Oxygenated blood from the lungs passes directly into the left atrium. The left atrium pumps the oxygen-rich blood into the arteries that conduct it to the various tissues of the body. Therefore, a three-chambered heart in reptiles allows the delivery of oxygenated blood with high blood pressure.

Sever21 [200]

This statement is false.

<u>Explanation:</u>

If the results are the same, a hypothesis turns into a theory first.

A hypothesis is an assumed statement which may or may not be correct. Special experiments are designed under controlled conditions to find out whether the hypothesis is correct or not. If the Hypothesis is correct, it becomes a theory. A theory is a sophisticated explanation of the results which is further refined to make a law.
