The answer is speed and not velocity because no direction is given.
A protein domain is a conserved part of a given protein sequence and (tertiary) structure that can evolve, function, and exist independently of the rest of the protein chain. Each domain<span> forms a compact three-dimensional structure and often can be independently stable and folded.
On the other hand, a motif is a </span>distinctive sequence<span> on a protein or DNA, having a three-dimensional structure that allows binding interactions to occur. Early on, clustering was used to detect common three-dimensional structural motifs in </span>proteins<span>.

Answer:
Explanation:
In terms of old school electron shells - One Hydrogen atom on it's own has an empty shell, and therefore to fill the shell it needs another electron. In the case of Helium, it already has two electrons at the same energy level - so it cannot accept any new electrons i.e. it cannot form new bonds.
Answer:
The correct answer is - compound light microscope
Explanation:
Growth bands in the scale of the fishes are used to determine and found out the age of fish by counting the number of annuli on a scale and proportional growth can find out by the space between scales.
A compound light microscope is a microscope that is used to examine or see the specimen that can not be seen by the naked eye or the hand lens, it provides the range of 40x-1000x magnification power.
