Answer:

Neither

Explanation:

It is important to note:

Enzymes can only be denatured but not killed as enzyme is not a living thing that can be said to be alive

temperature and pH may change the 3D shape of an enzyme, this destroy the active site of the enzyme thereby reducing its activity.

The diploid number for a lily whose pollen contains 12 chromosomes would be _________ and is produced when the pollen, containin
kirza4 [7]
The answers would be 24 and fertilises. 

Pollen is the male gamete of lily, which is a haploid cell, with only half the chromosomes of the normal diploid ones. Therefore, if the haploid gamete has 12 chromosomes, so the diploid would be 12+12 which makes 24. 

The egg is also a gamete of lily, but it's a female gamete. It is also a haploid cell, with only 12 chromosomes which is given in the question. So, when the sperm fuses and fertilises the egg, the zygote would have 24 chromosomes which is formed by 2 haploid gametes.

Afina-wow [57]

The correct answer is: B) The F1 variance is due only to environmental factors.

According to Mendelian genetics: he crossed two purebred parents with differing traits to be sure that there were no other factors contributing to the outcome of the cross. When two purebred parents are crossed, all of the offspring should be genetically the same (heterozygous).

In the example above, we can see that there is phenotypic variance among the offspring, so we can conclude that it must be due only to environmental factors.
