Question
1. Coenzymes are primarily made of a. Lipids b. Cholesterol c. Vitamins d. Proteins 2. Pseudostratified columnar epithelia would likely be found in the a. Brain b. Trachea 3. If a red blood cell were placed in distilled water, it would a. Remain the same b. Shrink 4. Arrector pili muscles function to a Control size of blood vessels b. Move skeletal bones c. Stomach d. Liver c. Change the color d. Burst c. cause intestines to contract d. pull hairs erect. 5. In.order for facilitated diffusion to occur a. Osmosis b. Lipids , is/are needed. c. Lysosomes d. A concentration gradient and carrierExplanation / Answer
1. c. Vitamins.
Because coenzymes are non protein molecules which are mainly vitamins, vitamin derivatives, or form from nucleotides.
2. b. Trachea
Because pseudo stratified columnar epithelia are mainly found in the linings of the trachea.
3. d. Burst.
Distilled water is an example of hypotonic solution which means it has less solute in it than a red blood cell. In this environment water would rush into the red blood cell to maintain equilibrium. As a result red blood cell became expand and perhaps even burst.
4. d. Pull hairs erect.
During cold, these tiny muscles help to generate heat by means of contract all at once, causing the hair to stand up straight on the skin.
5. d. Concentration gradient and carrier
Because this type of diffusion involving passive movement of molecules along their concentration gradient, guided by the presence of another molecule – carrier.
