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.

Answer:
Explanation:
Positive phototropism is growth toward a light source, and negative phototropism is growth away from a light source. ... Sunflowers are a great example of positive phototropism, because not only do their stems curve toward the light but their flowers turn to face the sunlight as well.
The correct answer is: smooth endoplasmic reticulum (smooth ER).
Smooth endoplasmic reticulum is a membrane organelle of the eukaryotic
cells which consists of tubular membrane vesicles. One of its main function is the synthesis of lipids and their storage. For example, cholesterol and phospholipids are stored in the smooth ER and then used for the synthesis of plasma membrane.
There is another type of ER- rough ER. The difference between these two ER on its outer surface have attached ribosomes- protein-synthesizing particles .
