Answer:
1. The body's immense blood supply (when blood vessels dilate or become larger heat loss occurs) When the blood vessels constrict it holds in heat
2. The skins blood supply also helps maintain body temperature (helps maintain homeostasis which is the "normal" state of our body)
3. Humidity in the air effects thermoregulation (heat regulation in the body) by limiting sweat evaporation (usually sweat evaporates into the environment when the humidity is low because the air has low "water levels" per say while you have high "water levels" because of your sweat
Answer:
When mechanical waves strike a barrier, at least part of the energy of the waves will be reflected back into the media from which they came.
Explanation:
she will have to listen to all of carefully while she is writing for example:

(pretend as i am her.)
"Hey mom, dad, brother come i see crabs!" as she writes it she focuses on how she writes and stops the video and back up again to listen so she can see if it was correct.
Answer: a.Oxygen combines with carbon of simple sugar.
In cellular respiration, the presence of oxygen results in the break down of glucose molecule is broken down into carbon dioxide and water. The energy is required for this process that transforms the glucose in the form of ATP. The oxygen is required to produce ATP. Later on more energy is produced by the process of oxidative phosphorylation. ATP molecules transfers energy to the cells, which are the chief source of energy and also get used up in this process.
Answer:
2.843 M
Explanation:
Molarity = moles / volume
<u>Milliliters to liters:</u>
500 mL <u>= .500 L</u>
<u>Grams to moles:</u>
MgO molar mass = 16.00 + 24.31 = 40.31 g/mol
57.3 g x 1 mol / 40.31 g = <u>1.421 mol</u>
<u>Molarity:</u>
1.421 mol / .500 L = 2.843 M
