Answer:
As your level of activity increases, your breathing rate increases to bring more air (oxygen) into your lungs so that your lungs can pump more oxygen into your blood and out to your muscles.
Answer:
We fear flying in a plane, nuclear power plants or being struck by lightning more because our risk perception isn't rational. We assess risks using a mixture of cognitive skills (weighing the evidence, using reasoning and logic to reach conclusions) and emotional appraisals. In this case, we believe that overheating or lack of exercise is something we can control. We believe we can feel the process taking place and we can react in time. We fear all the situations that we cannot control.

Answer:
D. Codominance
Explanation:
Codominance is when both alleles are expressed with the resulting phenotype being the intermediate of the two. For example, red and white phenotypes results to a pink one.
Hydrogen atoms in compounds such as h2 and H2o are joined to the molecules with covalent bonds. This is where electrons are shared between the atoms in order to fill there valence shells.
As we mentioned before, hydrogen can only form one covalent bond because its 1s electron orbital holds a maximum of two electrons. Hydrogen can form either a polar covalent bond or a non polar covalent ( cause there is no electronegativity difference between the two molecules).
Water contain polar covalent bonds because the oxygen has a grater electronegativity than the hydrogen atom.
