D bacteria are the main nitrogen transporters
Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
Answer:
$400
Explanation:
This is a simple multiplication question.
200kWh × $2/kWh = $400/200kWh
We are worried about the top number, because that is how much it costs the family to use 200kWh of electricity each month.
Final answer: $400 for 200kWh.
Explanation:
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
Tiny hair cells inside your inner ear help you hear. They pick up sound waves and change them into the nerve signals that the brain interprets as sound. Hearing loss occurs when the tiny hair cells are damaged or die. The hair cells DO NOT regrow, so most hearing loss caused by hair cell damage is permanent.
