B. 1pm in October
Lowest ozone levels ever recorded are in early October and in the pm (noon to 6 pm) air pollutions is at its lowest levels.
The right answer is decreased nonshivering thermogenesis.
The increase in metabolism allows an increase in the production of heat. Newborns use their brown fat as a source of heat, it is a non shivering thermogenesis.
The second mechanism for increasing heat in humans is increased muscle tone and shivering, but in the newborn there is no chill.
Answer:
I think C)The would have to take in and use more energy in order to break the covalent bonds.
Explanation:
Since hydrogen bonds are weaker than covalent bonds.
Carbohydrates are the main energy source. But lipids are used for storing energy so
Answer:
Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat. The total energy passed from one level to the next is only about one-tenth of the energy received from the previous organism.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up.
