you need oxygen when you exercise so you don't faint
smokers get less so it is harder for them, its like trying to exercise while breathing through a sponge or a straw os
<u>Answer</u>:
The two molecules generated by the Krebs cycle that pass their high-energy electrons to the electron transport are NADH and FADH2
<u>Explanation:</u>
The kreb's cycle gives NADH and also the another hydrogen carrier which is termed as FADH2. During the process of the electron transport chain, one NADH gives rise to electrons and also the hydrogen ions, which has enough potential energy that can convert and produce 3 ATP molecules. Again in the electron transport chain the NADH and the FADH2 undergoes oxidation and releases energy in the form of the ATP. The process of generation of the ATP in the electron transport chain(ETC) is also referred as the chemiosmotic phosphorolation.
Answer:
Dosage and form in which the chemical is present are the factors that determine the level of harm of chemical on the environment.
Explanation:
Dosage usually mean amount of chemical. Some chemicals cause harm to the environment in a very low amount and some chemicals damage the environment when the amount is too high, these chemicals are not considered as toxic. Form of chemicals also affects its toxicity. Some chemicals are harmful in one state and beneficial in another state.
Answer:
c) A study of how disease rates vary among different population groups
Explanation:
Epidemiology is the systematic and scientific study of the distribution of the health-related issue in a specified population.
The Epidemiologists studies the disease and its cause in a population by the collection of the data which gives an insight in the distribution of the health issues in the population living from a small area like school to a country.
The epidemiological studies help the society by reducing the risk of the negative health outcomes, in spreading awareness about the health issues and in framing the health policies.
Thus, Option-C is the correct answer.
Option 1 seems to be correct
