Answer:
<em>In a population, natural selection acts on phenotype of individuals.</em>
Explanation:
Natural selection tends to favour those organisms of a population which carry traits that allow them to be better adapted to the environment and these traits are passed on to their offsprings. Natural selection tends to act on the phenotype of the population whereas evolution is the phenomenon which changes the allele frequencies. Natural selection acts on individual organisms of a population whereas the change in populations, on the whole, arises due to evolution.

Answer:
The child may exhibit the following behavior during the evaluation: When the evaluators assign a task, it is difficult for the child to organize or finish the task, pay attention to details and follow instructions or conversations. because the child is easily distracted.
Other symptoms is that the child may not be sitting for a long time, and the child start running, jumping or climbing around the room.
Answer and Explanation:
Protein folding : It is the physical procedure by which a protein chain gains its local 3-dimensional structure, an adaptation that is normally naturally useful, in a quick and reproducible way. It is the physical procedure by which a polypeptide folds into its trademark and useful three-dimensional structure from curl. Every protein exists as an unfurled polypeptide or arbitrary curl when interpreted from a grouping of mRNA to a direct chain of amino acids. This polypeptide does not have any steady (dependable) three-dimensional structure (the left hand side of the primary figure). Amino acids cooperate with one another to create a well-characterized three-dimensional structure, the collapsed protein (the correct hand side of the figure), known as the local state. The subsequent three-dimensional structure is dictated by the amino corrosive grouping.
\The right three-dimensional structure is fundamental to work, albeit a few pieces of practical proteins may remain unfurled, so protein elements is significant. Inability to crease into local structure commonly creates inert proteins, however in certain occurrences misfolded proteins have changed or lethal usefulness. A few neuro degenerative and different ailments are accepted to result from the collection of amyloid fibrils shaped by misfolded proteins. Numerous sensitivities are brought about by off base collapsing of certain proteins, on the grounds that the invulnerable framework doesn't deliver antibodies for certain protein structures.
