Answer:</h2>
Generally, <u>D) non-metals are gases</u> which are at room temperature.
<h2>
Explanation:</h2>
Those metals which lack the property of the metal are called as non-metal. Usually they are characterized by the following features:
- Nonmetals don't conduct electricity through them.
- Nonmetals don't allow heat to pass through them.
- They don't show ductility and malleability.
- The nonmetals not only include gases but there are some solids which do not exhibit the above mentioned characters are also nonmetals. Some of the solid nonmetals includes graphite, carbon, wood, and so on.
Thus, from the above data, it can be inferred that option D which states that gases at room temperature is considered as most suitable answer for non-metals, as option A, B, and C are characteristic of metals.

Hope I managed to help in parenthesis my own ideas
Explanation:
-Foreground aquarium plants are ideally aquatic plants that are placed at the base of a hardscape layout, near the midground area. Alternatively, foreground aquarium plants are also referred to as carpeting plants.(small close to the ground usually bushes or small plants.(weigela, moss)
- Midground aquarium plants are ideally aquatic plants that are placed in the midground at a medium height of a hardscape layout. These plants really help to fill in the central focal point of a planted tank.(Medium size plants(sunflower) or small trees(new oak tree))
-
A background plant is a type of plant that provides a backdrop for smaller plants. A hedge can be a type of background plant design, if the hedge is lined with smaller flowers.(huge 200+ old trees dominating the forest)
From DNA to RNA, purines and pirimidines transform in this matter:
(A) adenine => (U) uracile ; because RNA has uracile instead of timine in DNA
(G) guanine => (C) citosine
mRNA: G U G C A C C U G A C U C C U G A G G A G
GUG-valine
CAC-histidine
CUG-leucine
ACU-threonine
CCU-proline
GAG-glutamic acid
GAG-glutamic acid
Hope this helps!
The ultimate source is mutation.It is the only way that new alleles and genes are created.
