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 
where n is the number of divisions. in the question it is given that the blastomere has 64 cells.
n=6
This means that the fertilized cell has to divide 6 times to develop into 64-celled blastomere.
Answer:
32%
Explanation:
According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%
That is, A + T + G + C = 100%
Where A=T and G=C i.e the proportion of each base pair is equal.
Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:
18 + 18 + A + T = 100
A + T = 100 - 36
A + T = 64
If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32
Hence, Adenine contains 32%, likewise Thymine.
Answer:
gogi apparatus and the rough endoplasmic reticulum
Explanation:
After the synthesis of proteins in their various site of production, thses proteins needs to be packaged into vessicle for transport to their destination. Vesicles that bud off from the Endoplasmic reticulum will then fuse with the nearest Golgi apparatus membranes, the cis-Golgi. these vessicles continue to travel using vesicle transport through the Golgi apparatus until they reach the end of the golgi appartus budding off — called the trans-Golgi. they are then transported to wherever they are either - the lysosomes, the plasma membrane etc.
History is the answer. Art, music and clothing are all trends where history is not
Charles Darwin is considered the father of modern biology, as he influenced more people than any other biologist. Also, evolution by natural selection is the most important part of biology.
