Answer:
Carotenoid, any of a group of non nitrogenous yellow, orange, or red pigments (bio chromes) that are almost universally distributed in living things. There are two major types: the hydrocarbon class, or carotene, and the oxygenated (alcoholic) class, or xanthophylls. Synthesized by bacteria, fungi, lower algae, and green plants, carotenoids are most conspicuous in the petals, pollen, and fruit (ex: carrots, sweet potatoes, tomatoes, and citrus fruits) of the flowering plants.
Explanation:
Answer:
b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.
Explanation:
Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.
When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.
Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.
Answer:
kidneys, renal pelvis, ureters, bladder and urethra.
Explanation:
Cells make up the tissues which combine to form the organs and then different organ systems make up the organism
so it's cells-tissues-organs-organ system-organism
