Since the corals lack the zooxanthella that are found in tropical coral reefs because the zooxanthella require sunlight and there is no sunlight, the corals are built upwards instead of across. The polyps build the coral this way because they are filter feeders. The correct answer is C, filter feeders.
The skeletons can be the same but have a different function, because they descended from a like ancestor. like a human arm and a bat's arm.
Answer: Gas exchange that occurs at the level of the tissues is called internal respiration. The correct option is C.
Explanation:
Respiration a process in living organisms involves the production of energy, with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances. There are about four types of respiration and these includes:
- Ventilation
- External respiration
- Internal respiration
- cellular respiration
In respiration, passive movement of gases by diffusion occurs between cell surfaces in a process called gas exchange. Without this process, oxygen cannot be taken into the cells and carbondioxide released. I hope this helps. Thanks.
Aerobic respiration produces more ATP than anaerobic respiration because aerobic respiration occurs when oxygen is present and is then able to produce ATP as normal with a profit. However, anaerobic respiration has a lack of oxygen, which leads to either fertilization, only producing enough ATP to keep the cycle going and the cell surviving, (not creating any excess/profit ATP).
The environment of an organism determines the selection pressures on it. For example, organisms with the ability to camouflage in a forest environment are more likely to survive, and be selected to pass their traits on.
