Which is NOT a type of protein?

A. Fibrous

B. Membrane

C. Globular

D. Unsaturated

Answer Explanation:

There are three types of proteins: fibrous, membrane, and globular. Fibrous or structural proteins consist of collagen, elastin, and keratin. Membrane proteins are interactive and anchored to a membrane. Globular proteins consist of functional proteins like enzymes, hemoglobin, and insulin.

Therefore unsaturated is the correct answer.

Therefore, the Correct Answer is D.

Q #1: Your class is competing with another class to determine who has the best plant color. Your class decides to test a couple of solutions to determine which would be best for overall plant color before competing. Starting with four sets of four plants, the class decides to water each set with a different solution. They water them once a week with 200ml of the following solutions: water, diet soda, 1% bleach solution, and a 1% salt solution. All plants are placed in the window that receives the recommended amount of light. After a month of testing, your class notices that only two plants are alive, but one of those two does not look healthy. Based on these results, which of the following would be a good hypothesis to design the next experiment around?

A. Plants need more than 200 mL of liquid per week.

B. Salt has no impact on plant health.

C. Salt contains useful nutrients for plants.

D. A combination of the solutions tested will produce healthier plants.

Answer Explanation

Since only 2 out of the initial 16 plants survived the whole month, it would be reasonable to test variables that were shared by all the plants. As such, the amount of liquid the plants need would be a good follow-up experiment. It is not specified as to which plants survived, so there is not enough information to think that testing the impact of salt is warranted. Additionally, since almost all the plants died, it is not reasonable to assume that a combination of the solutions would have an impact.
Q #2: Which of the following is a carbohydrate?

A. Cellulose

B. Hemoglobin

C. Estrogen

D. ATP

Answer Explanation

Cellulose is a complex carbohydrate that composes the better part of the cell wall.

Hemoglobin is a protein and is found in red blood cells. Adenosine triphosphate (ATP) is a compound used by living organisms to store and use energy. Estrogen is a steroid hormone that stimulates the development of female sex characteristics.
Q #3: Which of the following statements best defines an organelle?

A. Layer of polysaccharides outside the plasma membrane of cells

B. Abnormal Infectious proteins

C. Specialized structures within a cell

D. Collection of tissues used to serve a specific function

Answer Explanation

Organelles are specialized structures within a cell that serve a specific function. For example, mitochondria supply energy to the cell by generating adenosine triphosphate. Ribosomes are the site for protein synthesis. The nucleus is in charge of all of the activities of the cell.
