The process of evolution involves changes in the genetic makeup of a population over a period of time. sexual reproduction enhances variability among offspring. the random alteration of dna from parent to offspring, called mutations, also produces variable characteristics in offspring. some mutations can be , while others can be harmful and hinder survival. in this experiment, students mimicked random mutations and the ability to collect and eat food. each experimental group was timed for both collection and eating of the food, and data was collected to determine if the mutations were or harmful when trying to collect and eat food. of all the mutations, which one would most likely contribute to a rapid rate of extinction? a) blindness b) paddle hands c) no peripheral vision d) fused hands, no range of motion

Option A, Blindness

Explanation:

A blind person will definitely face problem to search food. Therefore, his/her ability to collect food will get hampered completely.

As compared to all other mutations, blindness will cause complete dependence of the affected individual on others for their food.  

In race of survival, the fittest species will survive and hence the blind individuals will die in lieu to inability to feed themselves.  

Therefore, option A is correct

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
