Question

1. the diagram below represents a cell. which letter indicates the specific structure where most hereditary mutations occur? (a) c (b) a (c) d (d) b 22. cells possess structures that perform specific jobs. which statement correctly pairs a cell structure with a function it performs in the cell? (a) the cell membrane synthesizes proteins for cell processes. (b) ribosomes regulate which materials enter and leave the cell. (c) vacuoles transfer genetic information from one cell to another. (d) the mitochondria provide energy for cell processes. 23. in single - celled organisms, materials are stored primarily in (a) mitochondria (b) nuclei (c) vacuoles (d) ribosomes 24. one difference between plant and animal cells is that animal cells do not have (a) chloroplasts (b) a cell membrane (c) a nucleus (d) centrioles 25. what is the main function of a vacuole in a cell? (a) storage (b) release of energy (c) coordination (d) synthesis of molecules 26. when viewing some cheek cells under low power, the cells need to be (a) to the left of the field of view (b) to the right of the field of view (c) below the field of view. (d) in the center of the field of view 27. which cell structure is correctly paired with its primary function? (a) vacuole - cell division (b) mitochondrion - movement (c) ribosome - protein synthesis (d) nucleus - storage of nutrients

Explanation:

1. Hereditary mutations occur in DNA, which is mainly located in the nucleus of a cell. Assuming the nucleus is labeled correctly among the options, we can determine the answer.
2. The mitochondria are the power - houses of the cell and provide energy for cell processes. The other options mis - state the functions of the cell structures.
3. In single - celled organisms, materials are stored primarily in vacuoles.
4. Plant cells have chloroplasts for photosynthesis, which animal cells lack.
5. The main function of a vacuole is storage.
6. When viewing cells under low power, they need to be in the center of the field of view for proper examination.
7. Ribosomes are responsible for protein synthesis.

Answer:

1. (Assuming the nucleus is the correct structure among the options)
2. D. The mitochondria provide energy for cell processes.
3. C. vacuoles
4. A. chloroplasts
5. A. storage
6. D. in the center of the field of view
7. C. ribosome—protein synthesis
