Answer:
Selective breeding of normal sheep with too much wool sheep.
Explanation:
Selective breeding can lead to some sheep overheating from having too much wool if the sheep of having more wool is crossed with normal wool so the offspring is produced with huge amount of wool on their body that keep its body warm in winter season and overheat in summer season. So the sheep shed their hairs in the summer season in order to reduce overheating of the body.
A ) if it s dna G with C and A with T so if it s C 32 G its 32 you have only 100% so it should be 100-32-32 =36 A=T so 36=A+T 64=2T T =18

c. 4 I and III only
Explanation:
The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.
Cleavage Planes:
Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.
Cell Differentiation:
Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
