Answer:
B. As snow and ice melt, the underlying surfaces absorb heat from solar radiation
Explanation:
Which of these is part of a feedback loop that results in a cooling effect on Earth as snow and ice melt, the underlying surfaces absorb heat from solar
Use the formula: v=v0+at
v is the final velocity
v0 is the initial velocity
a is the acceleration
t is the time
Plug in and solve for t:
0=6+(-2)t
<em>*Subtract 6 from both sides*</em>
-6=-2t
<em>*Divide both sides by -2*</em>
3 seconds=t
Hope this helps!!
<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
