Because different plants contain different vitamins and minerals as well as different amino acids and our body needs a large variety of these in order to preform all the necessary chemical reactions taking place inside our body. Some vegetables are very rich in a certain vitamin but are lacking in another, like how oranges have plenty of vitamin C but not iron. Vitamins and minerals are used in your cells to speed up and allow pretty much any chemical reaction to occur, but each one helps with a certain process and cannot simply be replaced by a different vitamin. In addition, very few vegetables contain all of the essential amino acids that work as the building blocks for protein synthesis and the creation of enzymes, so if you are not getting all of these in your diet, it is very unlikely you are producing enough enzymes and as a result certain functions in your body could stop working altogether.
Explanation:
Given that,
Weight of the friend, W = 600 N
When the friend sits on the metal frame it bends downward 4 cm, we can say that the compression in the it is 4 cm or 0.04 m
To find,
Spring constant for this chair or k
Solve :
The weight of an object is equal to the force exerted by the gravitational force, F = 600 N
According to Hooke's law, the force exerted by the spring is given by :
F = kx
k is the spring constant
k = 15000 N/m
Therefore, the spring constant of the spring is 15000 N/m.
Answer:
Well,
Explanation:
In this image, the thermal energy could be going both in an upwards and downwards direction. The chicken passes thermal energy to the salad under it. But at the same time, it is releasing smoke upwards, meaning it is also releasing thermal energy upwards.

Answer:
It is the carrier of genetic information.
Answer:
We know there's two forces acting on a book while it sits on a table:the force of gravity pulling it down, and the normal force of the table acting upward on the book. The book isn't accelerating while it sits there. That's because the weight of the book is being counteracted by the normal force of the table.
Explanation:
There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.
