Answer:
i hope Boron oxide is the name you're looking for.
Answer:
The correct answer would be -
Thymine to adenine
Cytosine to guanine
guanine to cytosine
<u>Adenine</u>, and <u>"U" uracil</u> respectively.
Explanation:
mRNA is a sequence of complementary base sequences encoded from a gene or DNA segment which is used to produce the protein by the process called translation.
From converting a sequence from DNA to its complementary mRNA sequence, the rules of complementary base pairing will be applied: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) and Thymine is replaced by adenine.
Uhh...

Do we eat leaves?

I mean, yeah, we do... basil leaves...
.
but really, what gives leaves energy?
.
huh?

Yup. The sun.

The sun never ends. See, the sun provides energy for plants. animals eat plants. we eat plants and animals.

No sun?

Answer:
Pure substance: sugar
A chemical change: occurs when methane is burned.
Explanation:
Pure substances have definite <em>constant compositions</em> (reflected in formulas) and have their own <em>chemical properties</em>. On the other hand, mixtures are made of two or more pure substances (<em>variable composition</em>) and their chemical properties depend on each combination. From the list, only sugar is a pure substance (C₁₂H₂₂O₁₁), whereas seawater, air, lemonade, and milk are mixtures.
Chemical changes (chemical reactions) occur when pure substances transform into others, and therefore there are new formulas. Conversely, in physical changes, pure substances <em>preserve their identity</em> (formula) but have changes in their <em>physical properties</em>. Methane being burned is a chemical change since new substances are formed:
CH₄ + O₂ ⇄ CO₂ + H₂O
Water vaporization, paper shredding and dissolution of solids in liquids are examples of physical changes.

Explanation:
In order to kill parasites and to make the water the be safe from microoganisms, boiling is a great procedure for making sure this happens, that is to say is the act of purification of water. However, when you over-boil water it also depletes the amount of oxygen present in the water.
When you boil water for the purpose of killing germs/ parasites, the PURIFIED PART IS THE WATER VAPOUR, the LIQUID WATER STILL HAS THE DEAD PARASITES IN THEM. That is the reason why the process called DISTILLATION is more efficient in purifying water is more efficient than ordinary boiling of water.
The liquid water remaining in the container after the boiling would have also been purified though, but it will still contain dead contaminants, so, filtering can be done or one can drink the water like that.
