Answer:
Ionic bonds are formed when electron are transferred
They are particles that create Proteins & Polypeptides.
Answer:
A constant allele frequency is maintained by populations in absence of natural selection as both the alleles for the trait impart equal survival advantage (adaptive) to the individuals under the prevailing conditions.
Explanation:
A population maintains constant allele frequencies in absence of evolutionary forces such as natural selection. This occurs when the existing allele frequencies of a gene are adaptive to the individuals. Both the alleles for a trait should be equally beneficial in terms of survival and reproductive success of the individuals under the given conditions. Therefore, both the alleles are maintained with existing frequencies.
Venus is closer to the sun
The main answer wold be diversity.
When you think about it, you only have a triplet code (which requires much less physical space than having all 64 possible codon combinations already present but either turned off or on). It makes much sense to have less actual physical compounds which can be combined in different ways (and a lot of ways) and produce the variety that can be required.
