defon

Answer:

The mecanism is termed as feedback inhibition.

Explanation:

In an enzyme catalyzed sequential reaction the end product of that reaction inhibits the activity of the activity of the enzyme catalyzing the ist step This type of  regulation is called Feed back regulation or feedback inhibition.

               The main function of human body is to maintain the homeostasis of the all the components it contains.When the end product of an ongoing enzyme catalzsed sequential reaction is produced in a high lebel at that time to maintain its own homeostatis that end product inhibits the functioning of the enzyme catalzsing the ist step of that biochemical reaction.

Design a controlled experiment to determine whether earthworms change the forest ecosystem.
Orlov [11]

"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."

Deciduous forest- A deciduous forest is one that is mostly made up of trees that shed their leaves in the fall.

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.
