Answer: it's because they need to provide a lot of energy.
Explanation: fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.
A I think but can you get a better picture of the questions
I’m on that same question
If a p53 gene is defective it may cause cell cycle to stop functioning normally. Without this cell cycle check, cells will divide continuosly creating many chromosomal damage.
You should use a Punnett Square for this question
The Punnett square predicts the offspring of two parents (two alleles). In this case you have brown eyes (Bb) and blue eyes (bb)
In the four boxes you should have Bb, Bb, bb and bb (50% chance of offspring with blue eyes and 50% chance of offspring with brown eyes).
The genotypes ratio will be 2Bb:2bb
And the phenotypic ratio will be 2 Brown : 2 Blue
