Seed dormancy allows for a seed to germinate only when the conditions are right to support the germination and growth of the plant. This adaptation, therefore, increases the chances of survival for the plant. Natural selection, which powers evolution, will always favor desirable traits which will be entrenched in a population through successive generations.
So what's the question here?<span />
Rough ER is dotted with ribosomes which give it a "rough" appearance. Smooth ER doesn't contain ribosomes. :) Hope this helps!

Answer:
1a - A chemical compound is a chemical substance composed of many identical molecules composed of atoms from multiple elements held together through chemical bonds. atoms of the equal element bonded in a molecule do not form a chemical compound, in view that this would require two different elements
1b - Inorganic compounds are critical within the body and responsible for many simple functions. The primary inorganic compounds are water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and a few acids , bases, and salts. The body is composed of 60–75% water.
2a - it helps with chemical reactions, cellular form and size and helps the cell regulate temperature.
2b - The chemical reactions vital for life would no longer occur or slow it down.
3a - carbohydrates, lipids, proteins, and nucleic acids
3b - Proteins and nucleic acids
3c - A carbohydrate has only Carbon, Hydrogen, and Oxygen, with the hydrogen and oxygen in the ratio 2:1. A protein is made of amino acids. ... So without nitrogen atoms, the compound cannot be a protein. it can be a carbohydrate, because it contains the elements of a compound. An organic compound contains only the elements carbon, hydrogen and oxygen.
