false statement: the cuticle slows down the loss of water in a leaf.
The correct answer is - quartz.
The quartz is a light colored, transparent mineral, with hardness of seven, and is characteristic that instead of cleaves it has fractures. This mineral is composed of silicon and oxygen atoms, which make a tetrahedral structure. It is the second most abundant mineral in the Earth's crust, just after the feldspar.
The dizygotic twins are also known as non-identical twins or fraternal twins. It refers to two siblings, which originate from distinct eggs or ova that are discharged at the similar duration from an ovary and are fertilized by distinct sperm.
As the dizygotic or fraternal twins are two distinct fertilized eggs, they generally give rise to two separate placentas, amniotic sacs, and supporting compositions.
Nitrogen is present in the environment in abundance but still we cant inhale nitrogen
<h3>
What is the role of nitrogen in our body?</h3>
Nitrogen is physiologically inert. It contributes nothing to the functioning of our bodies. The cells in our body need oxygen to live, not nitrogen. we can find nitrogen in our body in form of nitrogeneous base in nucleotide.
We inhale all gases present in air fills our alveoli, by the process of diffusion, only oxygen in the air is taken into the blood stream while the other gases along with the waste CO2 is exhaled. So you do breathe in nitrogen, but it is exhaled as it is by the body.
