Only 200 out of 2 000, 000 sperm cells reach the ovum. And only one (in exception to very rare cases of two) sperm cells actually participate in the process of fertilization. In comparison, an average female only produces 400 of egg cells during their lifetime, but the eggs cells are significantly larger than sperm cells.

- When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.
- While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.
<u>Hence</u><u>,</u><u> </u><u>we</u><u> </u><u>can</u><u> </u><u>conclude that</u><u> </u><u>breathing involves the movement of diaphragm and Rib cage</u><u>.</u>
Answer:
Its c
A pressurized water reactor does not boil the water!
Explanation:
- There are different type of nuclear power plants, that are used to generate electricity other than the water ,wind and solar electricity generation.
- The nuclear power plants use uranium as fuel that heat the water and the steam generated runs the turbine
- The most common type of nuclear power reactors are :-
The pressurized water reactor
- It heats boils the water to ane extreme temprature but it doesnt boil it that water due to the great amount of pressure it is under
The boiling water reactor
- the nuclear fission reaction of uranium generates great amount of enegery that is absorbed by the water and it starts to boil , the steam generated runs the turbines
Answer:
A punnet square can be described as a diagram which is made to check the outcomes of a cross.
To check the probability of the offsprings of a cross between homozygous dominant thumb shape parent with a homozygous recessive thumb shape parent, let's draw a punnet square:
t t
T Tt Tt
T Tt Tt
The results of the punnet square depict that:
Genotype: All of the offsprings will be heterozygous for the thumb shape trait. Tt will be the genotype.
Phenotype: All of the offsprings will show the thumb shape like the thumb shape of the dominant parent.
X-linked recessive disorders are typically common in males than in females as seen in the Royal pedigree.
<h3>What are X-linked recessive disorders?</h3>
X-linked recessive disorders are disorders which occur as a result of a mutation in the X chromosome.
X-linked recessive disorders are typically common in males than in females.
Females can be carriers but males are always affected when the mutation is present.
