| Question | Answer |
|---|---|
| Twenty-three chromosomes per cell in humans is referred to as: | Haploid |
| Extensive weight training causes the muscle cells to: | hypertrophy |
| Phagocytosis is an example of | Endocytosis |
| Water will move through the cell membrane by: | Osmosis |
| A sequence of three bases forms a(n | Codon |
| All of the following are examples of passive transport except | Endocytosis |
| NaCl would move through the cell membrane in which direction? | Both in and out of the cell |
| When the chromosomes align themselves across the equator of the spindle fibers, it is characteristic of which phase of mitosis | Metaphase |
| An individual’s entire set of DNA can be referred to as a | Genome |
| Two solutions of different concentrations of glucose are separated by a membrane that allows both glucose and water to pass through. When dynamic equilibrium is reached, there will be | an even exchange across the membrane |
| Diffusion of particles through a membrane by means of a carrier molecule is called | Facilitated diffusion |
| Materials can be moved from a low concentration to a high concentration through | Active transport |
| A membrane carrier structure attracts a solute to a binding site, changes shape, and releases the solute on the other side of the cell membrane. This describes the process o | carrier-mediated transport |
| During which stage of mitosis do the centrioles move to the opposite poles of the cell | Prophase |
| Transcription can be best described as the | Synthesis of mRNA |
| The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of | Filtration |
| A saline solution that contains a higher concentration of salt than a red blood cell would be | Hypertonic |
| Diffusion require | a concentration gradient |
