Answer:
correct.
Explanation:
cell will proceed to S phase for the duplication of chromosomes.
Answer:
Explanation:
The Genotype of the woman is XCbXN
The man XNY
Since the allele for the color blindness is carried on one of the X -chromosomes of the carrier mother, then the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal allele from the mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal X allele from the father.
Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes
1. XNY vs XCbXN.Then the one of the boys will be colorblind and the one of girls will be carriers. XNXCb, XNXN, XCbY,XNY 50 %
2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle
Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).
The proportions that will be the females since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls take the defective allele from the mothers and take normal from the father,they will all be carriers,since the X of the father is normal.
They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.
Answer:
a."Alkylating agents are toxic to tissues that have rapidly dividing cells."
Explanation:
In the given example the patient is about to begin chemotherapy with a bifunctional alkylating agent.
when the two dna strands are cross linked they will not separate for dna replication which will halt the cell division process so rapidly dividing cells will stop dividing and die
Moreover,Chemotherapeutic agents, also known as antineoplastic agents, are used to prevent the growth of fast-growing cells, usually in the sense of malignancy, directly or indirectly.
Therefore, Chemotherapeutic agents are Alkylating agents that are toxic to tissues that have rapidly dividing cells
So, this statement by student indicates an understanding of his chemotherapeutic agent.

2. The worst economy since the Great Depression
3. Communist Europe (the Helsinki Accords)
4. Richard Nixon
One month after taking over the presidency, Ford pardoned Nixon. This
caused a lot of controversy but Ford claimed he did it to save the
nation from the prospect of a long, messy, and divisive trial.
In 1974, President Ford also offered clemency to those who evaded the
draft during the Vietnam War if they would swear allegiance and perform
two years of public service. Similarly, those who deserted during the
war could return for two years in the branch they left to achieve
clemency. However, Ford was criticized both by those who felt he was
being to easy on the draft dodgers and those who had avoided the service
because they felt they were in the right.
In 1974, Ford asked for aid to be sent to South Vietnam as fighting had
resumed. Congress would not agree. In April 1975, Saigon fell and by
1976, North and South Vietnam were united into one country.
Ford escaped two assassination attempts, both by women. First on
September 5, 1975, Lynette Fromme, a follower of Charles Manson, pointed
a gun at him but did not fire. She was convicted of attempting to
assassinate the president and sentenced to life in prison. The second
attempt on Ford's life occurred on September 22, 1975 when Sara Jane
Moore fired one shot that was deflected by a bystander. Moore was trying
to prove herself to some radical friends with the assassination of the
president. She was convicted of attempted assassination and sentenced to
life in prison.</span>
