Question

extra tissue has formed in an organism due to uncontrolled cell growth. which of these most likely caused the extra tissue to form?
oa. the organism experienced a growth spurt.
ob. a mutation occurred that caused an increased rate of cell death.
oc. the organism suffered an injury.
od. a mutation occurred in the genes that control cell division.

Explanation:

• Option A: A growth spurt is a normal, controlled increase in body size and is not related to uncontrolled cell growth forming extra tissue.
• Option B: An increased rate of cell death would not lead to extra tissue formation. Instead, it would result in tissue loss.
• Option C: An injury typically leads to a healing process (which is a controlled process of cell division for repair), not uncontrolled cell growth.
• Option D: Genes control cell division. A mutation in these genes can disrupt the normal regulation of cell division, leading to uncontrolled cell growth and the formation of extra tissue (such as in the case of tumors).

Answer:

D. A mutation occurred in the genes that control cell division.
