- Helium has one neutron
Most helium atoms have two neutrons in it.

-Hydrogen has 2 protons, while Helium only has one
As stated, Hydrogen has one proton. Helium actually has 2 protons, electrons, and neutrons.

C. Insects are classified as omnivores in alpine meadow communities.

D. Biomass decreases as energy is transferred from one level to another

The answer is D. Biomass decreases as energy is transferred from one level to another

The energy pyramid being referred to is in the attachment below.

Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.

Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.

<h2>_____________________________________</h2><h3>TRISOMY 18:</h3>

Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.

Their work was mainly about love, humour, love and metaphysical conceits. Their poetry was often far-fetched with unusual metaphors or similes. The metaphysical poets wrote very different poetry from the general style of the other poets of their time. They were not interested in writing about the usual images of nature or classical mythology. </span>
