In captivity, tigers and lions have been known to interbreed and produce hybrids, known as ligers. Why does this NOT make them the same species, according to the biological species concept

Explanation:

A cross between a tiger and a lion will produce an hybrids. During fertilization it has been observed that both the father and the mother contributes equally to the genetic makeup of the offspring this therefore will make the liger have 50%gene from the tiger and 50% gene from the lion which is different genetic makeup from the parents.

Since the parents are of two different species the offspring will always be of a different species because its makeup is genetically different from the two parents it is a combination of two species forming a new species.

If the parental species are the same i.e two lion or tiger the offspring will be of the same species but a combination of the parental gene.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
