There are two ways of working out the phylogeny (family tree) of living animals. One is by analyzing their genes; the other is to analyze the extent to which they are similar in form. In either case. the results can then be integrated with the fossil record. In principle, the two approaches should be complementary. Both should lead to a consistent account of how snake and lizard families descended from a single stem. More or less a greater number of shared traits would mean they recently diverged from a common ancestor.

Lady_Fox [76]

The right option is Intolerance

Drug Intolerance is a situation in which drugs cause adverse effects such as drowsiness or stomach upset and the body is unable to tolerate or bear these effects.

Is asexual reproduction better when the environment changes or when the environment does not change?
Georgia [21]
Asexual reproduction produces genetically identical offspring and sexual reproduction creates variation in the offspring. When the environment changes and it affects the asexual offspring it will affect all identical copies whereas since the sexual offspring have more variation, they are more likely to survive.

In a protein molecule, the number of amino acid molecules may be as few as _____. 5 500 50 5,000
densk [106]

The correct answer is 50.

Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.

Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
