Answer:

A. No, because budding is a type of asexual reproduction.

Explanation:

Asexual reproduction is the process where an organism makes a copy of itself by itself. It does not require a mate to make offspring.

The offspring are genetically identical to the parent.

Budding is a type of asexual reproduction where a small outgrowth of the parent breaks off to become a new organism.

Embryo development is usually only discussed in the context of sexual reproduction, where two gametes fertilize one another and a new organism that is genetically different to either parent is formed.

Answer:

A. No, because budding is a type of asexual reproduction.

Explanation:

The buds on the side of the adult hydra is not an embryo because budding is a type of asexual reproduction.

It is sexual reproduction that produces an embryo from the fusion of gametes.

Hydra produces new ones by budding using part of its body wall.
This process is simply an outgrowth from the body wall.
An embryo is one of the stages of development of offspring originating from a zygote.
It is begins at fertilization to the formation of body structures.
Embryos are peculiar to organisms that reproduces sexually.

Answer:

The correct answer will be option-neural tube, hindbrain, metencephalon,

Explanation:

The development of the brain during the embryogenesis takes place by the formation of a neural tube or the predecessor of the central nervous system. The neural tube arises from the ectoderm layer of the gastrula where the anterior portion of the neural tube forms the brain.

The neural tube development results in the formation of three sacs filled vesicles in which the fist vesicle forms the forebrain, second forms the midbrain and the third vesicle forms the hindbrain.

Later development process divides the hindbrain into two new portions called metencephalon and myelencephalon where the metencephalon forms the cerebellum portion of the brain.

Thus, the selected order is the correct order.
