Answer:

Your answer should be bent angle

Explanation:

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. Hope this helped :)

Answer choices are:


A. Invalidate, because energy should not leave a closed system

B. Invalidate, because the amount of energy should stay constant

C. Validate, because an aquarium is an open system that loses and gains energy

D. Validate, because the amount of energy lost was replaced by matter.

The correct answer choice is:

C. Validate, because an aquarium is an open system that loses and gains energy.


Explanation:


As we know that, the law of conservation of energy is that the total amount of energy of an isolated system prevails to be constant, it is said to be maintained or conserved over time. This law means that energy can neither be created nor be destroyed; rather, it can only be converted or transferred from one form to another.

What best describes the difference between paracentric and pericentric inversion?
topjm [15]

Answer:

The answer is B.

Explanation:

Paracentric and Pericentric Inversions both are terms used to describe the action of inversing a part of the chromosome. But the main difference between the paracentric and pericentric inversions is that pericentric inversion, unlike the paracentric inversion, does include the centromere in the inversion process. So the answer is B, which is zero for paracentric inversion.

I hope this answer helps.
