In order for a cellular change to be inherited, this change must be present in the male gamete, or sperm or present in the female gamete, the egg or ovum. This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2, the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.
If we think about it logically, cellular changes in other parts of body should not affect the next generation. For example, if mom has skin cancer, it does not mean at all that the baby will have it as well.

The substance that needs more energy to undergo an increase of 25°C will
have a higher specific heat, because energy depends directly on
specific heat.
Q = cm∆T
where c = specific heat of the substance,
m = mass
∆T = temperature difference </span>
ANSWER- B
Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light corresponds to energies of the specific electrons.
Answer: Solids
Explanation:
In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
The first one is the 2Hg+.....
The second is the Ca+ 2H2O....
The third is the first one, H2 + Cl2...
And the last is Fe+ S= FeS
It was so easy
Good Luck
