Answer:
Chemical bonds contain potential energy.
Explanation:
Chemical bonds always contain potential energy. The atoms of the bond want to move to a lower energy to become more stable.. The energy for breaking bonds only comes when stronger bonds are formed. This energy is used to tear apart the bonds holding the Hydrogen atoms together. The strength of the covalent bonds depend on the overlap between the valence orbitals of the bonded Atom.
Question is which is NOT a good technique.
Answer is "B" and here's why:
A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.
B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.
A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration
<span>Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy </span>
<span>Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 </span>
<span>1.) Take a stop-watch </span>
<span>2.) Take TWO or more runners </span>
<span>3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up </span>
<span>4.) make the runners breath hard for air </span>
<span>5.) after finish line </span>
<span>6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) </span>
<span>7.) check the concerntration </span>
<span>8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race</span>
