Question

8 multiple choice 4 points a clade is an ancestor and some of its descendents an ancestor and all of its descendents all of the ancestors on a cladogram some of the ancestors of an organism found on a cladogram 9 multiple answer 4 points what is an example of something that might cause an induced mutation? select all that apply. radiation intense exercise x - rays smoking

Explanation:

• For question 8, a clade is defined as an ancestor and all of its descendants. This is a fundamental concept in cladistics in biology.
• For question 9, radiation (including X - rays which are a form of ionizing radiation) and smoking can cause induced mutations. Radiation can damage DNA, and chemicals in tobacco smoke are mutagens. Intense exercise does not typically cause induced mutations at the genetic level.

Answer:

1. an ancestor and all of it's descendents
2. radiation
3. X - rays
4. smoking
