    16. is obviously C because water can't become scarce in the ocean

    19. Which organelles are involved in energy conversion? (1 point) mitochondria and chloroplasts mitochondria and ribosomes smooth and rough endoplasmic reticulum Golgi apparatus and chloroplasts 20. What happens if you place human red blood cells in a concentrated salt solution? (1 point) They shrink as water moves from inside to outside the cells as a result of osmosis. They burst as water moves from outside to inside the cells as a result of osmosis. No change occurs as water freely diffuses back and forth across the cell membranes. The cells expend energy pumping water out in response to the greater external salt concentration. 21. What happens during photosynthesis? (1 point) Heterotrophs consume ATP. Heterotrophs produce ATP. Autotrophs consume carbohydrates. Autotrophs produce carbohydrates.

    26. How do aerobic and anaerobic respiration differ? (1 point) More energy is released from a glucose molecule during anaerobic respiration than during aerobic respiration. Anaerobic respiration but not aerobic respiration occurs in human cells. Anaerobic respiration requires oxygen while aerobic respiration does not. Anaerobic respiration evolved first; aerobic respiration evolved after photosynthetic organisms began producing oxygen. 27. Which of the following happens when a cell divides? (1 point) The cell’s volume increases. It becomes more difficult for the cell to get rid of wastes. Each daughter cell receives its own copy of the parent cell’s DNA. It becomes more difficult for the cell to get enough oxygen and nutrients. 28. During normal mitotic cell division, a parent cell that has four chromosomes will produce two daughter cells, each containing ____________. (1 point) two chromosomes four chromosomes eight chromosomes sixteen chromosomes
