Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis?

1 answer:

3 0

As their name suggest, the light dependent reaction requires light to occur while the light independent reaction can take place with or without light. But the light independent reaction requires the products of light-dependent reaction to start.

Answer:

c. carbon source

Explanation:

A "carbon source" refers to processes that hastens carbon release into the atmosphere more than what they absorb. Example of this is the burning of nonrenewable resources like fossil fuels.

The combustion of fossil fuels increases the release of carbon dioxide. Carbon is then being trapped into the atmosphere. This contributes to "global warming."

This is opposite to "carbon sink," which absorbs most of the carbon than they emit.

Atoms with a low ionization energy give up their outer valence electrons with ease true or false

umka2103 [35]

Answer: The given statement is true.

Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.

General equation of ionization energy is given by:

$X(g)\rightarrow X^+(g)+e^-$

If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.

And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.

Hence, the given statement is true.

List two species that may be threatened by the construction of a solar power tower

DENIUS [597]

Answer: the question is incomplete,below is the complete question.

List two species that may be threatened by the construction of a solar power tower in the California Desert

The answers are, Desert torties, mountain yellow legged frog and Joshua tree.

Construction of a solar power tower in the California Desert will threaten the existence of Desert torties, mountain yellow legged frog and and Joshua tree.

Explanation: The construction of solar power towers in Mojave desert in California poses a threat to the existence of quite a number of plants.The Mojave desert houses the largest solar power plant in the world,creating the solar power tower will create job opportunities for people but at the same time endangering the existence of about 12 rare plants that are found in the region of which Desert torties, mountain yellow legged frog and Joshua tree are greatly included,these plants cannot co-exist with solar thermal mirror arrays,this brings a controversy between energy/electricity generation and wildlife/ecosystem conservation.
