How many electrons does carbon have?(1 point)

Question

Responses

eight electrons (four in its inner shell and four in its outer shell)
eight electrons (four in its inner shell and four in its outer shell)

seven electrons (three in its inner shell and four in its outer shell)
seven electrons (three in its inner shell and four in its outer shell)

five electrons (three in its inner shell and three in its outer shell)
five electrons (three in its inner shell and three in its outer shell)

six electrons (two in its inner shell and four in its outer shell)

Answer 1

Carbon has six electrons. The correct configuration is two electrons in its inner shell and four electrons in its outer shell. Therefore, the closest response you provided is:

six electrons (two in its inner shell and four in its outer shell).

(Note: This option is not one of the responses you listed, but it accurately reflects the electron configuration of carbon.)

Answer 4

By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?(1 point)
Responses

This is not true because plants need to perform cellular respiration to break down the glucose into carbon, hydrogen, and oxygen.
This is not true because plants need to perform cellular respiration to break down the glucose into carbon, hydrogen, and oxygen.

This is not true because plants need to sequester nitrogen from the soil to build amino acids.
This is not true because plants need to sequester nitrogen from the soil to build amino acids.

This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.
This is true because photosynthesis produces glucose, and plants only need sugars, not amino acids or fatty acids.

This is true because photosynthesis produces glucose, which has carbon, hydrogen and oxygen—the building blocks for all biomolecules.

Answer 5

The correct response is:

This is not true because plants need to sequester nitrogen from the soil to build amino acids.

While photosynthesis does provide glucose, which is a source of carbon, hydrogen, and oxygen for the plants, they also need nitrogen from the soil to synthesize amino acids and nucleotides, which are essential for proteins and nucleic acids. Therefore, plants cannot create everything they need solely through photosynthesis.

Answer 8

hich compound is a reactant of both cellular respiration and dehydration synthesis?(1 point)
Responses

water
water

glucose
glucose

oxygen
oxygen

ATP

Answer 9

The correct response is:

water.

Water is a reactant in dehydration synthesis (where it is removed to form bonds between molecules) and is also produced during cellular respiration. However, while glucose and oxygen are reactants for cellular respiration, they do not play a role in dehydration synthesis in the same way water does.

Answer 10

Which compound is a reactant of both cellular respiration and dehydration synthesis?(1 point)

glucose
glucose

oxygen

Answer 11

The correct response is:

glucose.

Glucose is a reactant in cellular respiration, where it is broken down to produce energy. In addition, glucose can be involved in dehydration synthesis where it is used to form polysaccharides such as starch or glycogen by linking glucose molecules together, releasing water in the process.

(Note: While both glucose and oxygen are involved in cellular respiration, only glucose can be associated with dehydration synthesis.)
