Capsid is the part of the HIV Virus serves to protect the nucleic acid core.
1.When a water molecule is released during polymerisation, it's called a condensation reaction. What this means is that 2 molecules come together, but release water as a by-product. A water molecule needs to be introduced for the polymer to break apart (hydrolysis).
2.When a water molecule is needed during polymerisation, it's something called hydrolysis. What this means is that a when a water molecule is introduced, it causes 2 molecules to join. When the polymer breaks, water is released (condensation reaction).
3.Hydrolysis takes place to join 2 molecules together. When the polymer is broken down, water isn't released as a by-product.
(sorry that I couldn't help much on the last one).
Bacteria and fungi, compete for the same ecological niche.
Acoelomates.
They lack a coelom (body cavity)
Answer:
their very similar environments.
Explanation:
The type of evolution that is referenced here actually has a name -- convergent evolution. It's when two types of organisms/species have nothing in common ancestor-wise but still evolve similarly due to their similar environments. The similar body plan the question is referencing could include fins and other "fish features" as well. :-)
