Answer:
<em>The correct option is B) regulation of mitosis</em>
Explanation:
Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.
Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
To find the circumference we must work backwards from the area to find the radius of the circle.
Area = pi x radius squared
4 x pi = pi x radius squared
4 = radius squared
2 = radius
Now that we have the radius, we can plug it into our formula for circumference.
Circumference = pi x diameter (or 2 x radius)
Circumference = pi x 4
Circumference = 4
Answer:
widespread drought and increased crop growth
Different genes are activated in the blood cell than in the liver cell.
Explanation:
All the cells in the body contain the same number of genes and genetic material DNA but not all genes are expressed in a single cell.
The highly regulated process of the genes in molecular biology promotes the expression of particular gene required.
Signals from the cell environment activate the transcription factor that binds to regulatory regions of the gene, hence transcribing and making proteins for the same.
The genes for both blood cell and the liver are different but will be present in all the somatic cells, the regulatory mechanism will choose the required gene to be transcribed.
