You would want to approach the person and see if they are breathing and call for an ambulance.
Answer:
B) The mass of the reactants equals the mass of the products,
Explanation:
Given that the reaction is balanced, the mass of the reactants must equal to the mass of the products.
We know this by virtue of the law of conservation of mass.
The law of conservation of mass states that "in a chemical reaction, matter is neither created nor destroyed but atoms are rearranged".
Therefore, if the reaction is chemically balanced, the mass of reactants must be the same as the mass of the products in the reaction.
The second choice is the right one.

Answer:
GUA and GUG.
Explanation:
If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.
Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.
Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
Answer:
If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.
For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.
The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.
