Answer: Polar molecules have an uneven distribution of electrons that cause one end of the molecule to have a positive charge and the other to have a negative charge. ... This means that in a polar bond, the electronegativity of the atoms will be different. For nonpolar bonds the electronegativity of the atoms will be equal.
Explanation:
All of them!
Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. For example, a proton<span> is made of two up </span>quarks<span> and one down quark, while the atomic nucleus of </span>helium-4<span> is composed of two protons and two </span><span>neutrons</span>
1. theyre opposite because during photosynthesis CO2 is absorbed by plants and during respiration CO2 is emitted.
2. glucose is made during photosynthesis and serves as food for every (!) animal, and animals decompose glucose to CO2 during cellular respiration.
