Answer:
For question 20. I believe the answer is C. There would be more iguanas with webbed feet.
Explanation:
It states the iguanas have adapted to different habitats on the island. The iguanas that have webbed feet will be better at getting food in water, but slower on land. So if the land starts to disappear and turns into more water, the iguanas with webbed feet will have a higher chance of survival. Meaning the iguanas with out webbed feet will die out as a population.
Answer:
Lysosome
Explanation:
Freezer burn occurs due to the sublimation of ice in unprotected meat rich in muscles during long-frozen storage. It appears after thawing. The ice crystals rupture the lysosomes which in turn contain hydrolyzing enzymes.
Leakage of the hydrolytic lysosomal enzyme causes freezer burn and affects the appearance of the frozen meat. The hydrolytic enzymes of lysosomes partially digest the cells which in turn impart bad flavor to the stored food.
Dissolved Oxygen and Water Temperature. The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.
