Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.
401 of these offspring are expected to have long plumage.
To calculate the number of these offspring that are expected to have long plumage the following cross multiplication calculation must be performed:
- Total birds = 72 + 252 = 324
- Long plumage birds = 55 + 75 = 130
- 324 = 130
- 1000 = X
- 1000 x 130/324 = X
- 130000/324 = X
- 401.23 = X
Therefore, 401 of these offspring are expected to have long plumage.

Answer: Protein Synthesis (b)
Explanation:
DNA is very long and cumbersome. The strands of DNA also code many different proteins. To get the code for the desired protein from the nucleus to the ribosome in the cytoplasm, a copy of the small necessary section of DNA will be made. The copying process in known as transcription and it occurs in the nucleus. It is the first step in the protein synthesis which is the process of making protein.
