Answer: Breathing through a mask decreases the amount of oxygen we need to live & be. The only potentially toxic molecule that you routinely exhale is carbon dioxide. Carbon dioxide would not be trapped by a mask.
Explanation:
<span>They have similar or common ancestor. The similarities inherited from the common ancestor as in the case of homologous organs. In evolutionary biology a group of organisms share a common descent if they have a common ancestor. There are many other examples like in the case of hemoglobin to prove the theory of common ancestor</span>
The answer is electrons would be attracted to the comb.
Diffusion of one state of matter into another: Solid can diffuse in liquid. When sugar is added to water, whole water becomes sweet without stirring it because of diffusion of sugar into water. ... Carbon dioxide and oxygen are the two gases in air which dissolves in water by diffusion.
Answer: chemical bond
Explanation:
The chemical bond simply refers to the electrostatic attraction that can be found between ions that are oppositely-charged. It should be noted that the chemical bond occurs due to the transfer of electrons that is being found between atoms.
Therefore, based on the question given, the electrostatic attraction that is seen between a positively charged nuclei and the negatively charged electrons which hence allows two atoms to be held together is the chemical bond.
