Which woman will only be able to conceive using in vitro fertilization? karen, whose fallopian tubes are permanently blocked (or missing) rai, who is having trouble carrying a child to term ruth, who is over the age of 40 latasha, who is having trouble ovulating

Karen

Explanation:

Because the fertilization of an egg by a sperm occurs in the fallopian tubes, Karen will not be able to conceive without In Vitro Fertilization (IVF).

In Vitro Fertilization (IVF) is a process that involves fertilizing an egg (oocyte) with a sperm outside the woman's body.  If the fallopian tubes are only partially blocked, a woman has more options such as having a surgery to remove scar tissue or create another opening.

A woman who is having trouble ovulating or not ovulating at all can still conceive through ovulation induction, a chemical way of stimulating the release of an oocyte.

Ruth, who is having trouble carrying a child to term can employ the services of a surrogate mother.

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
