Which of the following explains why polar latitudes have a solar radiation deficit?
Answer:
The correct answer is - True.
The polar latitudes have a solar radiation deficit, and that is because of the shape of the Earth, and because of the way the Earth rotates and revolves.
The shape of the Earth, which is ecliptic, doesn't allow the solar radiation to have the same impact on every place on the planet. On the polar latitudes, the problem with the deficiency of solar radiation is because the sun rays fall at a very sharp angle, which means that the same rays are dispersed over a much larger territory, thus the heat is not concentrated, and these parts warm up much less.
The rotation and revolving of the Earth, also goes into the favor of the Equator, but not in the favor of the poles, as the Earth is rotating in an west-east manner, and while rotating it remains its track in a way in which the Equator is the most exposed to the solar radiation, but not the poles

Which of the following is an example of a pioneer species?
a. fungus
b. trees
c. shrubs
d. grass
Answer:
fungi
Explanation:
The grass is an example of pioneer species. Therefore, the correct statement is option D.
What is pioneer species?
Pioneer species involve the organisms that are first to colonize a newly formed or well-disturbed ecosystem. These species can grow in harsh environments, such as abandoned fields, or rocks.
Grasses are the pioneer species that can easily grow in harsh environments and establish and grow themselves in soils that contain poor nutrients. However, the growth of grasses in the soil enriches the soil with organic matter and makes the soil nutrient rich making it a suitable environment for other plants to grow.
When the grasses growing in the area makes the soil nutrient-rich, other plants such as shrubs and trees also begin to grow in that area, and with time, they replace the grasses as the dominant plant species.
Therefore, the grass is an example of a pioneer species.

Plants and animals exchange materials through the processes of photosynthesis and cellular respiration. Which of these statements is true about the way these two processes are related?
Answer:
This question lacks options, the options are:
A) The products of photosynthesis inhibit respiration
B) The products of photosynthesis are also the products of respiration
C) The reactants of photosynthesis are also the reactants of respiration
D) The products of photosynthesis are the reactants of respiration
The answer is D
Explanation
Photosynthesis and cellular respiration are two unique and distinct metabolic activities/processes. Photosynthesis is carried out by green plants and it involves the synthesis of glucose and oxygen using carbon dioxide (CO2) and water (H2O). Cellular respiration, on the other hand, occurs in every living organism and it involves the synthesis of energy using glucose and oxygen to produce carbon dioxide and water.
Based on the description of the two processes above, it can be observed that both processes are interrelated in the sense that the products of photosynthesis (CO2 and H2O) are the reactants of cellular respiration (C6H12O6 and O2).
The equation is as follows:
1) Photosynthesis:
6CO2 + 6H2O --> C6H12O6 + 6O2
2) Cellular respiration:
C6H12O6 + 6O2 --> 6CO2 + 6H2O

Explain how a nuclear power plant uses the process of nuclear fission to produce electricity.
Answer: In nuclear power plants, neutrons collide with uranium atoms, splitting them. In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity.
A nuclear power plant uses a nuclear fuel which undergoes bombardment by neutrons to produce energy.
Nuclear fission involves the bombardment of a fissile nucleus such as U-235 with a neutron. This results in the initiation of a chain reaction in which daughter nuclei are produced and tremendous energy is released,
The energy released in the process is used to heat water to produce steam. The steam thus produced turns a large turbine to generate electricity.

What best describes the geologic process of subduction?
1.when diverging plates pull apart from undersea ridges
2.when convergent plates collide and form mountain ranges
3.when a heavier transforming plate moves over the top of lighter plate
4.when a convergent plate meets and the heavier plate moves under the lighter plate
Answer:
when a convergent plate meets and the heavier plate moves under the lighter plate
Explanation:
Subduction occurs when heavier ocean plates move underneath land plates. This also causes magma to push up on the land and form rows of stratovolcanoes such as those on US Pacific Coast states.
The statement that best describes the geologic process of subduction is as follows:
When a convergent plate meets and the heavier plate moves under the lighter plate.Thus, the correct option for this question is D.
What is Subduction?Subduction may be defined as a type of geological process through which the tectonic plates are migrated to the edge of one crustal plate descending below the edge of another. Due to this, the oceanic plate runs into a continental plate.
The process of subduction takes place when the larger and heavier oceanic plates are migrated below the land plates. This stimulates magma to surge on the level of the land and constructs the column of stratovolcanoes.
Therefore, when a convergent plate meets and the heavier plate moves under the lighter plate is a statement that best describes the geologic process of subduction. Thus, the correct option for this question is D.

What role of vitamins and minerals as a source of energy?
Micronutrients are a type of nutrient that includes vitamins and minerals that are required in minute amounts.
Although micronutrients do not provide us with energy, they are necessary for the metabolic processes that allow us to obtain it from macronutrients such as carbs, protein, and fat.
The metabolism that produces energy also involves vitamin C, iron, and magnesium.
Two dioxygenase enzymes involved in the manufacture of carnitine, a crucial cofactor in the transportation of long-chain fatty acids into the mitochondria, require vitamin C to function.

Plants are autotrophs, organisms that produce their own food through the process of photosynthesis. The chemical reaction that describes photosynthesis is shown below. How does reducing the amount of light energy affect the products of photosynthesis?
Answer:
Reducing the amount of light energy also reduces the rate at which products are formed.
Explanation:
According to this question, plants due to their ability to capture light energy using their chlorophyll pigment are said to be autotrophs i.e. perform photosynthesis to obtain their food. Photosynthesis is a process that requires light energy from the sun, and it can be measured by the amount of O2 and glucose produced as PRODUCTS.
However, in a case where the amount of light energy is reduced, this means that the amount that will be captured by chlorophyll will be low, hence, reducing efficiency. This means that reducing the amount of light energy also reduces the rate at which products are formed.
