Answer:Hela cells represent cells of a cervical cancer used in several medical research to proffer solution to cloning,IVF, chemotherapy etc
Explanation:
Henrietta lackies died of cervical cancer and her cells ( which never stop growing or duplicating even at death,because of the malignancy)were taken without family authorization by John Hopkins to begin series of research which led to the discovery of chemotherapy treatment,polio vaccines, discovery of the exact number of human chromosomes, cloning just to mention a few.
The profits from these drugs i.e polio vaccines,IVF industry, genetics, chemotherapy treatment of cancer are known direct result of Hella cells, this are multimillion industry now.
Scientist benefitted by using Hela cells to resolve age long mysteries and problems,fact finding on human chromosomes , space exploration etc
Corporation like the fertility and pharmaceutical companies produced and sells drugs produced through research on Hela cells .
The lackies eventual discovery of the unauthorized use of Henrietta cells led to claims for the family.also cancer patients now have succour through chemotherapy which was discovered through Hela cells, infertility is now resolved through IVF ,all thanks to research on Hela
It is false that <span>team planning is most effective when the group leader develops the overall plan and then solicits feedback from the group. It must be the other way around. The role of the group leader is to stimulate ideas, facilitate discussions and summarize it all, to develop an overall plan that would make sense to the members.</span>
Answer:
4.5%
Explanation:
Stock R (Beta) = 1.5
Stock S (Beta) = 0.75
Expected rate of return on an average stock (Rm)= 10%
Risk free rate (Rf) = 4%
Required Return (Re) = Rf +(Rm-Rf) B
Required Return = 0.04 + (0.10-0.04) B
Required Return = 0.04 + 0.06B
Stock R = 0.04 + (0.06 * 1.50)
Stock R = 0.04 + 0.09
Stock R = 0.13
Stock R = 13%
Stock S = 0.04 + (0.06 * 0.75)
Stock S = 0.04 + 0.045
Stock S = 0.085
Stock S = 8.5%
Here, the more risky stock is R and less risky stock is S. Since, R has more beta than the Stock S.
= 13% - 8.5%
= 4.5%
