The amount of enzyme activity in a cell that is homozygous for a mutant allele is 20 units. The amount of enzyme activity in a cell homozygous for the WT allele is 10 units. It is known that 14 units of enzyme activity is required to show the trait. What is the dominance relationship between the WT and mutant allele for the phenotype of amount of enzyme per cell? A) The WT allele is dominant. B) The mutant allele is dominant. C) The WT and mutant alleles are codominant. D) The WT and mutant alleles show incomplete dominance. E) It is impossible to determine from the information given.

Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.
