Natural Selection

Question 11

Organisms cannot have different proteins in their cells for a particular feature

Accepted Answer

False

Answer

True

Question 12

Genes are instructions for proteins

Accepted Answer

True

Answer

False

Question 13

The two copies of a gene for each feature can only be the same version and provide instructions for only one type of protein.

Accepted Answer

False

Answer

True

Question 14

Each parent randomly passes on one of its two copies of each gene to its offspring. Each offspring, therefore, receives two copies of each gene, one from each parent.

Accepted Answer

True

Answer

False

Question 15

Through sexual reproduction, each offspring only inherits the same combination of gene versions from their parents. Therefore, siblings have the same traits from each other and their parents.

Accepted Answer

False

Answer

True

Question 16

Two mice have different parents. They both have the same proteins for whisker thickness in their cells. What can you say about the mice's whisker thicknesses?

Accepted Answer

They will have the same whisker thicknesses since their proteins for whisker thickness are the same so the proteins will connect in the same way.

Answer

They will have the same whisker thicknesses since all mice have the same whisker thickness.

Answer

They will have different whisker thicknesses because even with the same proteins for whisker thickness, the proteins can connect in different ways.

Answer

They will have different whisker thicknesses since only offspring from the same parents have the same whisker thickness.
