How do animals reproduce..can someone explain in detail please

Asexual reproduction in animals occur through fission, budding,e.t.c.

Sexual reproduction starts with the combination of a sperm and egg which is called FERTILISATION.

Explanation:

The reproductive parts in animals produce gametes that fuse and form ZYGOTE.

Okay, hope it helps.

Explanation:

Animals should be matured to reproduce.

The animals can reproduce sexually, that involves fusion of sperm and ova inside the body.

Few animals can also reproduce asexually, asexual reproduction does not involve the fusion of gametes, the genetic material is combined to produce an offspring that has inherited the genes of the parent.

i'm guessing this is from edg enuity so the answers would be, from top to bottom,

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
