Answer:

C is Snotase, because it works best in neutral environments (hence the pH of 7)

A is Flotase because it works best in acidic environments (low pH)

B is Zoomase because it works in acidic environments (low pH)

D is Floxase because it works in basic environments (pH above 7)

Note:

For pH, 7 is considered neutral. Anything below that is acidic and anything above that is basic.

Answer:

1. Enzyme C; 2. Enzyme A; 3. Enzyme B; 4. Enzyme D

The following image shows a cell before and during the process of mitosis. Before it undergoes mitosis, the cell contains 2n chr

svlad2 [7]

The correct answer is B: The cells will have 2n chromosomes and be diploid.

Diploid cell have two of each chromosome, one from each parent. When diploid cell undergoes mitosis, the result is two identical diploid cells (when haploid cell undergoes mitosis the result is haploid cell). This means that during the mitosis, cells reproduce genetically identical copies of themselves.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. E

Answer:

Because the offspring of a male and female are always going to be xx, xx, xy, or xy.

Explanation:

Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.

So we can write the this out in a punnet square as(link down below).

After you see the visual, you will find that the genotypes are xx, xx, xy, xy.

As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.

So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
