When the sheep dolly was successfully cloned, it was produced by growing an in vitro fertilized egg where the normal egg nucleus had been removed and replaced by a nucleus from an adult. since this nucleus is from an old mature animal, we would expect it to interestingly, tests show that this did not happen, a fact that currently puzzles researchers.

it is expected to have shorter telomeres

Explanation:

with aging, telomeres activities reduce resulting in shortening, thus, since the nucleus was replaced with an older one, it is expected that the telomeres length will shorten.

Explanation:

Because pressure is an expression of energy, the higher the pressure, the more potential energy in a system, and vice versa. Therefore, a positive Ψp (compression) increases Ψtotal, and a negative Ψp (tension) decreases Ψtotal. Positive pressure inside cells is contained by the cell wall, producing turgor pressure.
