In a hydra, digestion is completed _________.
OLEGan [10]

In a hydra, digestion is completed intracellularly.

Hence option (a) is correct.

Small, freshwater organisms of the phylum Cnidaria and class Hydrozoa are grouped under the genus Hydra. They are indigenous to temperate and tropical climates. 

The digestion takes place intracellularly in Hydra.

Because of their ability to regenerate and the fact that they don't appear to age or experience old age, hydra have drawn the attention of biologists.

Like most other cnidarians, hydras have a pretty straightforward digestive system.

They have a two-way digestive system, which differs from mammals in that food and waste enter and exit through the same aperture. A "blind gut" is the name for this configuration.

The center of the hydra's body is occupied by its digestive tract.

When trying to determine the rate of cellular respiration (an aerobic process), why is oxygen measured and not carbon dioxide
dusya [7]

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.

Carbon dioxide:

Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.

There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).

Now, carbon dioxide is emitted as a byproduct in both types of respiration.

Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.

Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.

Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.

Review the water cycle diagram below. What would be the effect on the mountains if the ocean were not nearby?
musickatia [10]
<span>D. There would be much less precipitation and evaporation.

Much of the precipitation comes from the evaporation of water from the ocean and posterior condensations into clouds that go over the mountains. If the mountains were to be far from the ocean, there would be much less precipitation and, therefore, evaporation also. </span>
