Answer:

D. analogous.

Explanation:

Analogous organs can be defined as organs, which show similar functions, but do not having common origins. Organisms that possess analogous organs do not share common ancestor as their organs are derived from different origins.

Examples of analogous organs include wings of bats, birds, and birds which are evolved independently, but share common function (flying).

Thus, the correct answer is option (D).

What should i know about proteins?​
katrin [286]

Proteins  are unbranched polymers constructed from 22 standard α-amino acids.

The protein show four levels of structural organisation; the primary structure, secondary structure, tertiary structure and quaternary structure.

The structure of proteins are stabilized by peptide bonds between the amino acid and hydrogen bond between the peptide chainds.

The primary structure of a protein is determined by the sequence of amino acids, but secondary and tertiary structures of protein define their natural or native conformation.

The solubility of protein varies according to the pH, ionic strength, nature of solvent, temperature etc.

Proteins can be classified as simple proteins or conjugated proteins on the basis of their composition.

The proteins can also be classified as fibrous proteins or globular proteins on the basis of their shape.

Proteins play a major part in body structure and function as most of the molecules like antibodies, immunoglobulins, hemoglobin, myoglobin ,most of the enzymes are proteins.

So proteins are also called building blocks of the body.

Describe how selective breeding of wolves has lead to the breeds of dogs we see today?
SpyIntel [72]

Well, what happened was that you had populations of dog-wolves that became isolated from the greater wolf population and in doing so, they began to breed more closely—to inbreed as it were. And when you inbreed, you get genetic peculiarities that arise, and those peculiarities then begin to become part of the population…. In other words, a mutation will appear in a small population.
