Answer:
A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.
Explanation:
Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.
Answer:
I'm pretty sure the answers for this is D, C, and B.
Because the different environments permit some organisms to thrive, while others cannot. ... Similarly, a fish (extremely suited to its aquatic environment) can't survive out of water. A characteristic which allows growth in one environment will not necessarily allow growth in another.
The genetic code can be defined as a set of rules used to encode information from genetic material (DNA or RNA ) into proteins. There are sequences of nucleotide triplets, -codons which specify which amino acid will be added next during translation (protein synthesis). Genetic code consists of 64 codons and this means that some amino acids are specified by more than one codon.
Genetic code has a role to determine amino acid sequence of protein (primary structure of protein). Location and the function of all those synthesized proteins is determinated by regulatory genomic regions (gene regulatory codes).
Proteins perform a wide range of functions within organisms such as catalysing metabolic reactions, DNA replication, stimuli response, structure role, transport role. So, all the diversity of organisms on this planet is due to protein variety.
I think the answer is evolution.
