Answer 1

Answer:

a) Method B is the asexual method of reproduction.. in this method a small outgrowth called bud grows on the side of the parent hydra,and gradually grows into a baby hydra which when developed completely detaches itself from the parent hydra. this is called budding.

b) the organisms produced asexually are genetically identical to each other and to the organism that produce them because in this method of reproduction only a single parent is involved and thus only it's DNA is present in the growing new individual.

c) Hydra reproduce in two ways depending on the season.

The first, asexual method, involves budding new individuals from the body wall. Basically, a branch of the body cylinder is produced, with a digestive cavity, which is continuous with that of the parent, tentacles and a mouth at the top.

Eventually the base will pinch off from the parent, becoming a new separate hydra. This is an asexual process because no fusion of sexual cells is involved and new individuals produced in this way are genetically exactly the same as their parent.

This is the usual method of reproduction in warmer months.

As it begins to get colder, sexual reproduction may start to take over. Most Hydra species have individuals which are either male or female. Eggs are produced in the outer body wall of female hydra and are fertilised by sperm released into the water by neighbouring male hydras. Some species of Hydra are hermaphrodite, with each individual having both male and female reproductive organs.

The seasonal timing of sexual reproduction is a way of helping the species survive over the winter. This is because the fertilised eggs have a tough shell or covering and can form a resting stage over cold periods. In the spring, the shell softens and a new hydra will emerge.
