Answer:
The nucleus
Explanation:
The nucleus contains chromosomes that contain genes
Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.
<h3>What we know about evolution. </h3>
- This is a theory that was put forward by Charles Darwin.
- Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
- The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
- These changes are hereditary.
Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.

Answer:
Individual-level protective factors
Explanation:
Psychological resilience is the ability of the humans to recover very quickly from the difficult situation mentally and socially.
The traits shown by the resilient person are due to self-esteem, problem-solving skills, good health, self concept and many others which are considered individual-level protective factors as these factor help increase the well being of the individual.

Pancreas
It is a large gland behind in the stomach that secretes digestive enzymes in the duodenum. Inside the pancreas are Islet of Langerhans. It is considered as an endocrine gland producing various hormones. Pancreas also produce pancreatic enzymes that act as digestive enzyme that assist in digestion and absorption of nutrients in the small intestine. These helps to break macromolecules such as carbohydrates, proteins and fats.
Answer:
Alternative splicing explains how it works
Explanation:
Two different transcripts can be produced from one single gene according to the nature of exons and introns of every transcript, which means that a group of exons will form the future mRNA molecule. The nature of this phenomenon is based on the function and local that every transcript will act. These mRNA transcripts are the result of how the RNA polymerase and transcription factors interacts with DNA molecule and therefore selects the number and the size of the exons and introns of each mature mRNA transcript.
