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:
They became closer to each other.
Explanation:
When skeletal muscles contracts the Z lines that are at the end of every sarcomere became closer to each other due to the fact that the I bands that are attached to the Z lines and contains the myosin filaments move closer to each other interacting with the actin filaments and shorten the the H zone that is in the middle of the sarcomere. In other words, It all becomes compact during a contraction.
Answer: c. This mating will demonstrate that these elephants are members of the same species and will produce fertile offspring.
Explanation:
A species is a group of organisms capable of interbreeding to produce viable offsprings. The Sri Lankan Elephant and the Indian Elephant are the same species so, they will produce fertile offsprings. Because they are from different geographical location does not mean they won't mate and produce fertile offsprings.
Answer:
Somatic; Germ line
Explanation:
Somatic mutations are the type of mutations that do not affect offspring or are not passed to the next generation. the occur mostly in the body cells/ somatic cells. Such mutations can be passed to daughter cells during mitosis but can not be passed to offspring via sexual reproduction. Germline mutations occurs in the germ line cells which gives rise to cells that are passed down to offspring. Germline cells gives rise to the sex cells that which are passed to offspring through the process of sexual reproduction involving the egg and the sperm.
