A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
I guess it should be deletion
Below statements are true:
<span>Acetylation of histone tails is a reversible process.
</span><span>Acetylation of histone tails in chromatin allows access to DNA for transcription.
</span><span>DNA is not transcribed when chromatin is packaged tightly in a condensed form.
</span><span>Methylation of histone tails in chromatin can promote condensation of the chromatin.

Answer:
Omalycus Raf and Hypoblema Lloyd
Explanation:
Having 2 chromosomes that are divided will give you a chance of getting one of them of 50%. Calculation of the probability as follows:
<span>Probability = 0.5^12</span>
<span>Probability = 0.00024</span><span>
So, you have a chance of 1 in 4167. Hope this answers the question.</span>
