<span>Endo genic literally means 'within work' ie driven by energy. So the answer that is correct will be option B ie " A large amount of energy is required to activate the reaction."</span>
The average radius of a molecule of Iysozyme, an enzyme in tears, is 1430 pm.
The size of an element's nucleus and also the total number of electrons around it grow with an element's atomic number. The radius of an atom increases with increasing atomic number.
The calculation of conversion of radius is shown below:
It is known that, 1 meter is equal to 10¹² picometers.
We can use a conversion fraction to convert 1430 picometers to meters.
1430 pm × (1 m / 10¹² pm) = 1.430 × 10⁻⁹ m
1 meter is equal to 10⁹ nanometers.
Now, use a conversion fraction to convert 1.430 × 10⁻⁹ meters to nanometers.
1.430 × 10⁻⁹ m × (10⁹ nm/1 m) = 1.430 nm
Therefore, the radius of nanometers will be 1.430nm

Explanation: I suggest: A freeze occurs when the temperature drops below 32 degrees, and frost can happen when the air temperature (which is measured about six feet above the ground) is up to about 36 degrees. If part of your yard is lower than the rest, it’ll probably be coldest there since cold air is heavier and sinks down.
Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
