I believe the correct response would be A. Lysosomes.
Answer:
Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles
Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.
Ribosome: A small particle in the cell that can make proteins.
Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.
Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.
Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.
Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)
Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).
Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.
Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.
Answer:
Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should.
For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body.
Answer:
Option C
Explanation:
Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.
Answer:
Even when equilibrium is reached, particles of a solution will continue to move across the membrane in both directions. However, because almost equal numbers of particles move in each direction, there is no further change in concentration.
