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.

Answer:
True
Explanation:
The species that went extinct could be a food source for another and that would possibly be detrimental to the chain.
That fact can be explained by the similarity in their genes.
Dogs and coyotes are from the same class, family and genus (Mammalia, Canidae, Canis).
This is almost enough for their offspring to be viable. But if the DNA is similar (which it is) offspring the chances of viable and fertile offspring is high almost at 100%.

Happy homework/ study/ exam!
Answer:
It is important to use the regulatory sequence of a milk gene when constructing a recombinant gene used to produce a human protein secreted in milk because<em> it is capable of increasing or decreasing the expression of specific genes within an organism.</em>
Explanation:
<em>Regulatory Sequence</em> is<em> a segment of a nucleic acid molecule</em> which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses.
<em>Genetic codes contains <u>ORGANISMS.</u></em>
