Answer:
I'm not sure if the answers are supposed to be creative, but these are my guesses based on biological definitions:
1. A fungus that is a decomposer ( saprotrophs )
2. An photoautotrophic tree would be a producer (all trees are photoautotrophs: pine trees, redwood trees, fruit trees, etc)
3. A heterotroph - this is very vague as the question is vague. These can be either primary consumers or secondary consumers. Either way, they are not producers and are consumers.
4. Black / brown bear - omnivorous consumer
If a cell is placed in a hypertonic solution, water will <u>leave the cell, and the cell will shrink.</u>
Answer:
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
Answer: The concentration of the cytoplasm of red blood cells will be 0.5m.
Explanation: Red blood cells that are bathed in blood neither shrink nor swell and burst because the concentration of the surrounding blood is equal to the concentration inside the cytoplasm of the red blood cells. This means that the two solutions are isotonic. Since the two solutions are isotonic, there will not be movement of water molecules across the red blood cell membrane. Osmosis do not occur between two solutions of equal concentration, for osmosis to occur water molecules must move from a region of high water concentration to a region of low water concentration through a selectively permeable membrane.
