Answer:ATP, Endergonic, Phosphate group, ATP synthase, Exergonic

Explanation:

1. ATP is the energy currency of the cell. The energy released from the hydrolysis of ATP is use to drive cellular work.

2. ATP are used to drive endergonic reaction. Endergonic reaction are energy requiring hence ATP is hydroxyze to release energy to power endergonic reaction.

3.ATP is formed when a phosphate group is transferred to ADP. Which is an example of endergonic reaction

ADP+Pi+free energy→ATP+H2O.

4. The oxidative phosphorylation of ADP to ATP is catalyze by the enzyme ATP synthase.

5. ATP synthesis is an endergonic reaction in which free energy is needed to phosphorylate ADP to ATP and the reaction is driven by Exergonic reaction.

A region experiences frequent landslides from heavy rains. How can the local residents lower the frequency of landslides in the
cestrela7 [59]

Answer: There are two possible effective choices

A. Start contour plowing on the slopes where landslides happen.

E. Reduce the slopes where landslides occur.

Explanation:

Plowing can help flow water through the slopes instead of it all building up in one area all at once. But reducing the slopes can slow landslides due to the smaller incline, but will not completely get rid of them.

Bogdan [553]

Organic compounds, such as carbohydrates, lipids, proteins and nucleic acids within the human body are referred as macronutrients.

These various macronutrients play different role in body like carbohydrates are used for energy (glucose). Fats are used to break food into fatty acids and protein helps in making hormones and muscles.

These macronutrient helps in the prevention of disease, provide energy to the body. All the macromolecules except the lipids are known as polymers.

Polymers are the natural or synthetic substance that are composed of large molecules that is called macromolecules.
