The answer would be Four.
1. DNA unzips in the nucleus.
RNA polymerase binds to the DNA sequence, separates the two strands and creates a single-stranded DNA molecule that will be transcripted.
2. Transcription occurs.
Transcription is the first step of gene expression. During this process, a gene's DNA sequence is copied and a mRNA molecule is produced.
3. mRNA moves to the ribosome
The mRNA is then transferred from the nucleus to the ribosome, the organelle that serves as a site for protein synthesis.
4. Translation occurs
Translation is the process where a mRNA sequence into the amino acid sequence of a polypeptide (protein).
5. Protein assembled at ribosome.
Translation, meaning the formation of a protein, occurs on the ribosome.
The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.

The US population most closely represents a clumped pattern, as humans are social animals who interact regularly. The United States has higher populations near major cities, which generally have more resources than rural areas.
Answer:
The humans use this limb to grab things, body language, and sign language.
The dogs use this limb for all kinds of weight-bearing activities like walking, jumping, running et cetera.
Birds use this to fly and whales use it as flapper.
The limbs of all these four animals are the example of homologous organs that is, they all are similar in structure but adapted to perform different functions during the course of evolution.
For example, in all four organisms, the limb is made up of the same set of bones such as humerus, radius, ulna, carpals, metacarpals, and phalanges.
Homology in structure shows that they must have evolved from a common ancestor and diverge to perform different functions as an adaptation to the contrasting environment.
