How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.

Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction

Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.

<h3>What is negative gravitropism?</h3>

Negative gravitropism occurs when shoots develop in the opposite direction of gravity toward sunlight.

Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.

Thus, the given experiment shows negative gravitropism.

Answer:

The title should be C: Humanity Spreads: Air Pollution and Deforestation

Explanation:

"Humanity Spreads: Air Pollution and Deforestation"

This tittle refers to how fast the population is growing in every aspect and how it is affecting natural resources. People keep moving to the cities looking for a job, studies, or a better life quality. As this happens, cities increase in size, which implies more human activity, more air pollution due to transport gas release, or factories gas release. Water is also polluted. Deforestation also increases because new buildings are constructed in new areas, or because agricultural activity keeps expanding to new places. Deforestation is the cause of death of so many species, not only plants but also animals that use to have shelter and food in this vegetation. By deforesting air quality is also affected as trees are not able to produce gas exchange.
