Answer:
e: pleiotropy
Explanation:
<em>Pleiotropy is a genetic term that describes a situation in which a single gene controls the expression of multiple traits. </em>
Depending on the underlining mechanism, there are different types of pleiotropy:
- gene pleiotropy: this occur when a protein representing a gene interacts with other proteins or catalyses multiple reactions
- developmental pleiotropy: this occur when mutation of a gene have multiple phenotypic effects
- selectional pleiotropy: This occur when the phenotypic expression of a single gene has multiple effects on fitness.
In this case, cystic fibrosis gene has multiple phenotypic effects which include its effects on the lungs, pancreas, digestive system and other organs.
<em>The correct option is e.</em>

<u>A Eudicot flowering plant is a plant that comes up with two seed leaves during the process of germination. Generally, Eudicot plants are characterized by netted venation of leaves, floral parts in 4/5 or multiples, and ring arrangement of vascular bundles.</u>
Three major above-ground structure of a typical Eudicot include;
1. <em>The stem</em>
2. <em>The leaves</em>
3. <em>The flowers</em> (for those that have reached maturity)
Two major below-ground structures of a typical Eudicot include;
1. <em>The roots</em>
2.<em> The root hairs</em>
Answer:
A. Earth's tilt on its axis
Explanation:
Because of the earth's tilt, during part of the year the NE US is angled towards the sun, but the other part of the year it is angled away from the sun. This is what gives us our seasons.
