Question

1. Which of the following statements is NOT true of current-living bacteria (Eubacteria)

1. Peptidoglycan cell wall                             c. Often named by their shape
2. Cellulose cell membrane                          d. Capable of motion

2. Which of the following components is NOT one of the 4 main types of organic molecules?

1. Nucleic Acids/DNA                                   c. Minerals/Micronutrients
2. Amino Acids/Proteins                              d. Fatty Acids/Lipids

3. In a scientific experiment, the variable that provides direct observable, changes to the data as it is directly influenced by the experiment’s conditions, would be known as what?

1. Control variable                                       c. Dependent variable
2. Independent variable                               d. Sample size variable

5. 4. The specialized integral protein found within the plasma membrane, whose specific function is to transport water is known as:
   1. Integral Membrane Protein                     c. Aquaporin Membrane Protein
   2. Peripheral Membrane Protein                 d. Internal Membrane Protein

Answer 1

1. Cellulose cell membrane       

Bacteria made up of peptidoglycan cell wall not cellulose membrane.

2. c. Minerals/Micronutrients

Carbohydrates, Fats, Proteins, Nucleic Acids are 4 main types of organic molecules.

3. c. Dependent variable

4. c. Aquaporin Membrane Protein

Aquaporin is a special membrane protein which transfer water molecules only.
