Luminosity is the total energy that star produce in one second, depending on both the radius of the star and on its surface temperature. Thus, all the star's properties such as its temperature, size, brightness and life span is determined by its luminosity.
Co2 is a product in cullular respiration,
Remember that the product is the result of the process
Answer:
The correct answer is spinal cord.
Explanation:
A reflex action is an instantaneous response movement caused due to stimulus. This is an involuntary action which is controlled by the neurons of the spinal cord through a pathway called reflex arc.
Answer: D
Explanation: Water's high surface tension is due to the hydrogen bonding in water molecules. Water molecules form these bonds in the liquid as well as deeper in the liquid.
<span>DNA, also known as deoxyribonucleic acid, belongs to a class of polymeric organic macromolecules called nucleic acids.
The only other member of this class is ribonucleic acid, or RNA.
Nucleic acids were first discovered in 1869 by the Swiss scientist
Friedrich Miescher.

<span>DNA and RNA play
important roles as genetic information carriers in biology, enabling the
mechanisms of heredity and protein synthesis. Nucleic acids are
polymers of nucleotides, which are composed of a five-carbon sugar, also
called a pentose sugar, a nitrogenous base and a phosphate group. The
sugar is deoxyribose, in the case of DNA, and ribose, in the case of
RNA.</span>
