Answer:
The average conversion energy from producers to primary consumers is b. 10%.
Explanation:
This percentage actually holds true for all transfer of energy at any trophic level in the food chain. Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy. It is important to note that energy cannot be created nor destroyed, it is simply transformed from one form to another.
Answer:
When a bullet strikes, a characteristic ‘keyhole’ is formed—a defect that is circular at one end with tangential fractures radiating outwards in parallel, allowing the bone between them to lever out. So, in other words a major surgery is needed to get the bullet out. It is very risky as well
Explanation:
Answer: The length of the cell in millimetres is 0.0015.
Explanation:
Given conversion :
Thus 
Given : Length of the cell = 1.5 micrometers 
To find: Length of the cell in milllimeters (mm)
Length of the cell in milllimeters (mm) = 
The length of the cell in millimetres is 0.0015.
Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.
