Yes, because the envelope can be a important document- so therefore it can be considered "confidential".

True or false? nucleotides can be broken apart from a single strand of rna by hydrolysis reactions.
Tomtit [17]
The statement above is TRUE.
RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar phosphate backbone of RNA is broken, thus cleaving the RNA molecule.
This reaction is made possible in RNA because the ribose sugar in RNA has hydroxyl group at the two prime position.

aliya0001 [1]
Answer: skull size of each species

Over time, it is the size of the skull  particulary that of the jaw bones, that can help determine the evolutionary relationship of two hominid species. It was believed that the jaws of hominids change as time passes by because the size of the brains changes too.

How a polymer molecule is synthesised by glucose?
Kay [80]

Answer:

As a new covalent connection develops between the two glucose molecules, one loses a <em>H group,</em> the other loses an<em> OH group</em>, and a <u>water molecule is freed</u>.

<h2>Why does glucose form a polymer despite being a stable molecule?</h2>

The formation of glucose polymers (glycogen, starch, cellulose) requires the input of energy from uridine triphosphate (UTP). Any tiny molecules must be converted into bigger molecules, which is compatible with the second rule of thermodynamics. Building proteins from amino acids, nucleic acids from nucleotides, fatty acids and cholesterol from acetyl groups, and so on are examples. Energy is released when bigger molecules are broken down into smaller ones, which is compatible with the second rule of thermodynamics. Thus, glucose may be converted to CO2 and H2O, resulting in the production of ATP. While glucose is a tiny molecule and hence relatively "stable," it can exist at a potential energy level and may be used to build up (needs energy) or broken down (<em>produces</em> energy). All of these biochemical processes require the use of enzymes; otherwise, the activation energy of most reactions would require extremely long periods of time for random energy inputs to push the reactions in either direction, despite the fact that energy considerations favor spontaneous breakdown over synthesis.
