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.

Think about an academic subject (biology) that inspires you. describe how you have furthered this interest inside and/or outside
Mashutka [201]

Answer:

Biology is the study of Living organisms whereby they are clustered into distribution , origin , behavior , anatomy their physiology and morphology.

Biology as a subject has changed my views and conspiracies about the existence of organisms in their ecosystem .Its like from biology you get to know the meaning of life in details right from the origin to death of the organism .

As a human being I have realized much on how biology helps even beyond the class , since I have learnt the reason why each organism belongs to a certain habitat and specific niche of the ecosystem , I have learnt to respect and conserve such organisms as they deserve to exist in that habitat , and their is an interdependency whether direct or indirect .

Also with the knowledge I have acquired on anatomy and the physiology of organisms , I can do  a first aid to an individual who has suffered outdoor pass outs or injuries to reduce the impact of the situation before he or she reaches the hospital .

I believe biology has impacted a very important part of my life and I look forward to take further studies in this field to broaden my knowledge even more .
