Romashka [77]

Answer:

nucleic acids.

Explanation:

The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.

Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.

snow_tiger [21]

Answer:

Cold temperature and higher pH cause the oxygen-hemoglobin saturation curve to shift high reflecting that hemoglobin releases more oxygen.

Explanation:

In higher pH i. e. neutral or alkaline and low body temperature, the hemoglobin molecule attach more oxygen to their active sites. When the temperature of the blood increases, the hemoglobin stops or reduces the binding of oxygen to their active sites and lower the saturation level.    Oxygen-hemoglobin saturation level refers to the amount of oxygen binds with the hemoglobin. This saturation decreases with increase in temperature and lower pH while saturation level increases when the temperature of the body is lower and pH is high.
