Answer:
Explanation:
Pericentric inversion results in chromosome have extra copies of some genes while some genes do not have copies. It can result in slow growth rate.
If a man is heterozygous of pericentric and a woman is heterozygous of pericentric although they do not show symptoms there is 25% chance that their offspring will have it and 50% chance of them being a carrier.
T t × T t will give TT T t T t t t
If the father is not heterozygous of it but the mother is heterozygous they have 0% chance of having it and 50% chance of being heterozygous a carrier of the disorder
T t × TT will give TT TT T t T t
Answer:
James Watson and Francis Crick with their DNA model at the Cavendish Laboratories in 1953.
Explanation:
b. Gravitational constant
Explanation:
G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.
- The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".
Mathematically, the law is expressed as:
F = G
Where F is the gravitational force
G is the gravitational constant
r is the distance
m is the mass 1 and 2 bodies

Each organism is unique because of genetic variation. Each set of genes we inherit from our parents codes for a specific trait. And our DNA is a blueprint for these traits. Not everybody contains the same genes and that is why we are all so beautifully unique.
Answer:
The correct answer will be option A.
Explanation:
The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.
This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.
Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.
Thus, option-A is the correct answer.
