Answer:

The punnet square will be completed as follows:

       T        t

T     TT     Tt

T       TT     Tt

A punnet square can be described as a diagram which shows the results of a cross.

The cross shows that the female parent carries homozygous alleles, TT, whereas the male parent carries heterozygous alleles, Tt.

The offsprings from this cross will have 50% probability of being homozygous as the female parent and will have a 50% probability of being heterozygous like the male parent.

Beginning with a cell that just fertilized ( 1 cell ) how many times must it divide to become a 64 cell blastomere ?
natka813 [3]

A cell that just fertilized has to divide 6 times to form a 64 cell blastomere.

<u>Explanation:</u>

Human reproduction begins with the fusion of male gamete sperm and female gamete ovum. The fusion of sperm and ovum forms the zygote that is diploid. The zygote then undergoes mitotic division to develop into embryo.  

The zygote first divides into two and the two individual cells divide again to form four individual cells and so on. Thus the number of cells after each division can be represented by the equation 2^n  where n is the number of divisions.  in the question it is given that the blastomere has 64 cells.

2^n=64  

n=6

This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.

Imagine an organism with mutations in complexes I, III, and IV that prevent pumping of hydrogen ions into the intermembrane spac
satela [25.4K]

Answer:  ATP synthase will not convert ADP to ATP.

Explanation:

Cyanide poisons the mitochondrial electron transport chain within cells and causes the body to be unable to obtain energy (adenosine triphosphate-ATP) from oxygen. Specifically, it binds to the a3 (complex IV) portion of cytochrome oxidase and prevents cells from using oxygen, causing rapid death.

Therefore, ATP synthase takes advantage of the protonmotrial force created during the Krebs cycles when cytochromes as electrons pass pump protons into the intermembrane spaces of the mitochondria. As the protons return to the matrix, ATP synthase uses this potential energy to convert ADP to ATP.
