It takes about one minute for a blood cell to make a complete circuit of the human body.
Answer:
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.

<span>The part of the ear where sound wave compressions and
rarefactions cause the eardrum to vibrate is the middle ear. The 8th
nerve in the inner ear actually converts the mechanical energy to electrical
energy for transmitting to the brain. A membrane called the tympanic membrane
separates the middle ear from the outer ear. Whenever a sound reaches the ear,
it creates a sound wave that creates vibration in the eardrum. The pressure
when high pushes the membrane inwards while low pressure sound waves helps the
eardrum to come outwards. </span>
A=2
B=red blood cells rely on catalase, catalase decomposes hydrogen peroxide
C=The effect of replacing his is that the hydrophobic amino acid would not do well with water
D= the hydrophobic amino acid is like oil and water and wouldn’t do well decomposing hydrogen peroxide
Answer:
Runoff is nothing more than water "running off" the land surface.
<h3>Explenation:</h3>
Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
