Would an opah fish be better suited to live in cold water or warm water? explain why
Kaylis [27]

Don't blame me if you get it wrong i'm a dumb but yet successful student

Warm blood gives deep-sea fish a boost, according to Wegner. The opah's muscles and nervous system likely function faster than an equivalent fish with cold blood. ... This fish, the southern opah, lives in colder waters than the northern opah, so it would be harder to keep warm, Wegner said — but even more beneficial.

Compound b has a molecular formula of c7h16o. what is the unsaturation number (un) or double-bond equivalent (dbe)?
aksik [14]

Answer: -

Zero

Explanation: -

Double bond equivalent or level of unsaturation is the number of unsaturation present in a organic molecule. The term unsaturation may refer to a double bond or a ring system.

The double bond equivalent for an organic compound can be found out by the help of the formula

DBE = C+1 -0.5 H - 0.5 X + 0.5 N

The chemical formula of the compound B = C₇H₁₆O

So there are 7 carbons, 16 hydrogens and 1 oxygen. There is no halogen or nitrogen.

Plugging into the formula,

DBE = 7 + 1 - 0.5 x 16

      = 0

Thus there is no unsaturation or double bond present in the compound B with the molecular formula C₇H₁₆O
