Answer: The light reactions of photosynthesis. Light is absorbed in the energy is used to drive electrons from water to generate NADPHN to drive protons across a membrane. These protons return through ATP synthase to Make ATP.
Explanation:
Answer:
A source from which organisms generally take elements is called exchange pool (option B).
Explanation:
Options for this question are:
- <em>Food web.</em>
- <em>Exchange pool.</em>
- <em>Reservoir.</em>
- <em>Biotic community.</em>
The term exchange pool is related to the biogeochemical cycles that exist in nature, referring to the source from which elements present in the environment become part of living organisms.
<u>Exchange pools are the biotic components</u> -like animals and plants- of an ecosystem, which determine the passage of elements between living beings. An element can remain as a reservoir (abiotic) in the soil, and then be incorporated into the exchange pool.
increased absorption of solar radiation by the atmosphere can affect precipitation in increasing absorption of solar radiation can lead to more rain and freezing rain and less hail and snow.
- B. Increased absorption of solar radiation can lead to more rain and freezing rain and less hail and snow
<h3>What is absorption of solar radiation?</h3>
Most of the absorption of solar radiation at wavelengths in the infrared range is due to water vapor and occurs in the troposphere, where most of the water vapor is located. This part of the absorption presents great variability due to the distribution of water vapor.
With this information, we can conclude that When solar radiation penetrates the Earth's atmosphere, it undergoes attenuation caused by reflection, scattering and absorption by atmospheric constituents.

Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
The three important agents which are involved in chemical weathering are –water,, carbon dioxide and oxygen. Among the three most important chemical weathering agent is water. With a simple formula H2O, the two hydrogen atoms bonded to one oxygen atom. This structure of water gives it a polar molecule property due to which it can polarize itself into negative and positive poles. The hydrogen is the positive pole with (+1) charge while the oxygen is the negative pole with (-2) charge and they attract ions opposite to their charge numbers.This exerts a molecular force on the surrounding molecules and they dissociate to get polarized and form new molecule. This process is called hydrolysis where a mineral is dissolved in water and ions from the minerals are carried away. These elements undergo the process of leaching.
