Question

Answer 1

ans is:- $\huge\mathfrak\red{heya\:Mate}$

zygote l

Answer 2

Answer:

(1) Zygote

Explanation:

Zygote

A zygote is a eukaryotic cell which is formed by a fertilization event between the two gametes. The zygote's genome is a combination of the DNA in each gamete which contains all of the genetic information of a new individual organism. In the multicellular organisms, zygote is the earliest developmental stage.

Morula

The morula stage is the stage of development during which the dividing cell mass has 20–30 cells and it resembles a mulberry.

Blastula

The ball of cells is referred to as a blastula I'm which one cleavage produced around 100 cells. The blastula is usually made up of a hollow spherical layer of cells and is referred to as the blastoderm which surrounds a yolk or fluid-filled space called the blastocele or blastocoel.

Gastrula

Gastrula refers to a hollow ball of cells whxih is used later in the embryonic development process to begin the formation of a gastrula during the process of gastrulation. The tissue layers of the developed gastrula will developed into the tissues and structures in an adult animal.
