Which of the following is NOT a reason body cells go through mitosis?
Organisms use mitosis to add new cells to increase their size.
Organisms use mitosis for reproduction.
Organisms depend on mitosis to repair damaged tissues.
Organisms rely on mitosis to make specialized cells, such as skin, blood, and nerve cells.
Why do chromosomes occur in pairs?
Used as a cloning technique to make offspring.
The chromosomes are attracted to each other.
Each parent gives the offspring one of every type of chromosome.
Each parent gives the offspring two of every type of chromosome.
Mr. and Mrs. O’Malley have 3 children. You can tell that the children are brothers and sisters. Why do they not look exactly alike?
Each child received a different combination of genes from each parent.
The children received DNA from their step-parents.
Each child received the same DNA from their parents.
A child might receive more DNA from one parent than the other.
