UV is capable of messing with cells on the molecular level, so it ought to be capable of producing the occasional mutation. Whether such mutations can get into the reproductive system is another question.
Answer: the heat
Explanation:
see a silicon dosent
obsorb as much heat as metal say if your coking something and you have a pan then the pan gets hot a silicon really absorb the heat as fast
Answer:
They regulate the cell cycle by phosphorylating other proteins
Explanation:
they are serine-threonine kinases, they play an important role in the phosphorylation of other proteins. Cyclin-CDK complexes phosphorylate substrates appropriate for a particular cell cycle phase and without that, the cycle cannot continue.
Answer:
Microtubules
Explanation:
These filament-like structures are a major component of the cytoskeleton of the cell and help is maintain asymmetrical cell shape. They are composed of tubulin molecules arranged to form a 'hollow straw' attached to the cell membrane end to end . The contraction and lengthening of these microtubules are controlled by the addition of removal these of tubulin molecules to vary its length.
