Question

Trace the sequence of events that lead to development of chick from the fertilized egg of a hen​

Answer 1

Answer:

1)After fertilisation takes place inside the body of the hen, the fertilised egg or zygote divides repeatedly to form embryo which travel down the oviduct. 2)As it travels down the oviduct, many protective layers are formed around the embryo. ... The embryo takes about 3 weeks to develop into a complete chick.

Answer 2

Mitochondria may have a number of different shapes.[23] A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins.[17] The two membranes have different properties. Because of this double-membraned organization, there are five distinct parts to a mitochondrion:

the outer mitochondrial membrane,

the intermembrane space (the space between the outer and inner membranes),

the inner mitochondrial membrane,

the cristae space (formed by infoldings of the inner membrane), and

the matrix (space within the inner membrane).

Mitochondria stripped of their outer membrane are called mitoplasts.
