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: The given statement is true.
Sun is the ultimate source for energy on the Earth. It is the natural and renewable source of energy on earth as it can easily be renewed and never run off. All living organisms which are present on earth are dependent on food for survival. For this, they become part of the food chain which provides them energy in the form of food. Food chain begins with plants as they are the primary producers in the food chain. They get energy for preparing food from sunlight in the form of light energy.
Moreover, the life forms which existed millions of years ago were dependent on sun for energy. The dead remains of these life forms have provided the non renewable sources of energy like fossil fuels on earth.
Thus, the sun is considered as the ultimate source of energy on the Earth.

In general, the toxicity of a substance depends on the following factors.
- Chemical type and inherent behavior.
- Dosage, in particular the link dose-time.
- Exposure route.
- Species.
- Stage in life, such as child, young adult, or an older adult.
- Gender.
- Fitness to drink.
- Metabolism.
- Allocation inside the organ.
- Excretion
- Human safety, including organ function and childbirth, requiring physical effects that can affect toxicity.
- Nutritional status
- Many chemicals are available.
- Circadian rhythms (the time of day caused by a medication or other substance)
