When an enzyme is denatured the active site which allows it to catalyze reactions is destroyed, rendering the enzyme useless. This process is irreversible but the remains are recycled to form new enzymes.
The factor that is responsible for the phenomenon of the blood group B being almost absent in Native Americans whose ancestors arrived in very small numbers about 10,000 years ago would be called the 'founder effect'.
Answer:
A lunar eclipse can only occur when there is a full moon.
Explanation:
A lunar eclipse occurs when the Moon, Earth and Sun are aligned on a straight line. This alignment completely blocks the sunlight and moon is under the shadow of Earth. In this phase, moon often look red because of reflection of infrared radiations. This happens only where there is a full moon.
It is not possible to occur moon eclipse in any phase because if sunlight would reach the moon surface directly, it is not a moon eclipse Further, lunar eclipse can last upto a few hours because the shadow of Earth is greater because of its size compared to the moon's size and it takes a while until moon is completely out of that shadow. Lastly, a lunar eclipse doesn't create an eerie color in the sky rather a red color due to infrared radiations.
Since enzymes function as organic catalysts, a cell would not be able achieve homeostasis if the required enzymes were not present.
