What is the significance of the phrase "nearly all energy on Earth originates from the Sun"?

B) It highlights the Sun's role in supporting life.

A) It indicates that energy is infinite.

C) It suggests that energy cannot be created or destroyed.

How do the building blocks of organisms relate to the concept of macromolecules?

Building blocks combine to form complex macromolecules.

Building blocks are not related to macromolecules.

Macromolecules are made of only one type of building block.

Building blocks are smaller than macromolecules.

What role do lipids play in living organisms?

They store energy and make up cell membranes.

They are involved in genetic information storage.

Which of the following best explains why plants and animals have developed different ways of obtaining energy?

They have evolved different adaptations to survive.

They live in different environments.

They have different cellular structures.

They are made of different elements.

What might happen if a plant could not perform photosynthesis?

It would not be able to produce the energy needed for survival.

It would be able to survive by consuming animals.

It would thrive in low-light conditions.

In what way do proteins differ from carbohydrates?

Proteins are made of amino acids, while carbohydrates are made of sugars.

Proteins provide energy, while carbohydrates do not.

Proteins are found only in animals, while carbohydrates are found only in plants.

Proteins are smaller than carbohydrates.

Why is understanding the structure of macromolecules important for biology?

It allows scientists to predict how molecules will behave and interact.

It helps in the classification of organisms.

It is not important for biology.

It only matters for studying plants.

Which of the following lists the reactants (inputs) needed for photosynthesis to take place?

light energy, carbon dioxide, water
