Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Rutherford gold foil experiment led to the discovery that every atom has a nucleus, its mass and all the positive charge are concentrated in it and also that most of the atom is mostly empty space.
It was performed in 1911 by Rutherford and his coworkers Ernest Marsden and Hans Geiger. They bombarded fast moving alpha particles on thin sheets of gold foil.
Most of the alpha particles passed through the sheet while few were deflected from their straight path. A small percentage of particles also bounced back from the foil. Since the alpha particles are positive so there must have been something positive inside the atoms that deflected and bounced back the alpha particles. So it led to the conclusion that the center of atom is positively charged.

The pituitary gland releases the antidiuretic hormone when more water is needed in the bloodstream.
Pituitary gland is a pea-sized gland which is located at the base of the brain and is vital for the development, growth as well as the functioning of the endocrine glands of the body.
Whenever, more water is needed in the bloodstream, the pituitary glands releases the antidiuretic hormone or the ADH. This hormone is produced naturally in the hypothalamus and helps in the constriction of the blood vessels and also helps the kidneys to regulate the amount of water as well as salts in the body.

A) ATP is the correct answer
Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)
In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.
XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.
