Answer: (b) Cholesterol</h2>
Explanation:
As the name suggests, cholesterol is a sterol (a modified steroid). It is biosynthesized by animal cells.
The alveoli. These little air sacs are found on the end of the bronchioles and are the place where oxygen enters the blood and the carbon dioxide leaves.
That isn't even possible. Your body is made of them. If you had none then you wouldn't be existing.
Answer:
The grasshopper doesn't have to use it circulatory system to carry gases to and from the grasshopper cells because the air that is passed through the trachea system is already close enough to get to the cells.
Explanation:
"In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process. There is not even an oxygen-carrying pigment in insect hemolymph." - www.biology-pages.info

Answer:
ribosome, cell membrane, nucleus
Explanation:
The organelles that perform similar functions in both plant and animal cells among the listed organelles would be <u>the ribosome</u>, <u>the cell membrane</u>, and <u>the nucleus.</u>
First of all, chloroplast and cell wall are limited to the plant cell only. Animal cells do not have these organelles.
The ribosome functions as the site of protein synthesis in both plant and animal cells. The cell membrane acts as a channel for the control of the movement of materials in and out of the cells and is found in both plant and animal cells. The nucleus is also present in both cells and serves as the control unit of the cell by housing the genetic materials and dictating how the cells will behave.
