<span>When practicing birth control as natural family planning, it is not true that it is almost 100 percent effective. Birth control as natural family planning does require careful tracking of the menstrual cycle, demands focus on bodily changes, and does require women from having sex on days ovulating and following. Even if sex is is had outside ovulating days, it is possible to get pregnant, thus it is not 100 percent effective.</span>
Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.
Anaemia is defined as the decrease or the reduction of the oxygen carrying content of the blood which are the red blood cells.
These red blood cells and other blood cells which include the white blood cells and the platelets are produced in the body by the bone marrows by a process called haemopoiesis.
The bone marrow is divided into two:
- yellow bone marrow and
- red bone marrow.
The red bone marrow is made up of stem cells which can be converted to red cells when the need arises while yellow bone marrow is made up of fat.
During health conditions such as anaemia, there is increase in the need of red blood cells by the body.
There is usually the conversation of yellow bone marrow to red bone marrow to compensate for the increased demand of red blood cells.
This conversation is called an adaptive conversation.
Therefore,Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

I'm pretty sure the answer is B
Answer:
(A). Sexual reproduction increases genetic diversity, and asexual reproduction can be more rapid.
Explanation:
Sexual reproduction is a mode of reproduction, which involves formation of new organisms by combination of genetic information from two organisms of different sexes. The major advantage of sexual reproduction is to develop genetic diversity as new organism is produced by mixing up genetic material of both the parents.
On the other hand, asexual reproduction involves formation of new organisms from a single parent having identical genetic makeup as present in parent cell. One of the major advantage of asexual reproduction is to produce high number of offspring in less time as it is more rapid than sexual reproduction.
Thus, the correct answer is option (A).
