The process of evolution involves changes in the genetic makeup of a population over a period of time. Sexual reproduction enhan
ces variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, 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 helpful 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
The skin is consist of keratinized cells that will keep multiplying. The cells start at the stratum basale and will keep moving up changing the old ones until it ends up at the outermost layer of stratum corneum.This process will take time around 2 - 4 weeks.
All systems would be working together but the main ones would be would be the digestive system, muscular system, nervous system, and circulatory system.
