Green crabs (Carcinus maenas) are hyperosmotic regulators in brackish waters. When water salinity is lowered, a green crab respo
SashulF [63]

Answer:

Explanation:

Green crabs have chemoreceptors located on an <em>antenna</em>.

These are long segmented appendages near the crab´s eyes that have both chemoreceptors and allow them to feel the surroundings.

Crabs also have antennules, like short appendages close to the antennas that allow them to <em>sense</em> their environment. A crab can "taste" using hairs on their mouthparts, pincers and even its feet.

So they can detect the salinity of the water by "taste" using the antennules. If these antennules are bathed with nonsalty water, the information the crab´s brain receives is to increase the salinity of its body by the system explained above, increasing its rate of urine production.

I hope it helps!

A fossil was found and determined by radiometric dating to be 11,400 years old. what is the ratio of carbon-14 to carbon-12 in t
LuckyWell [14K]

The answer would be 25%

Carbon 14 is radioactive material with 5700 year of half-time which will change it into carbon-12, a more stable substance. If the age of the fossil is 11,400 years old, then the amount of half-time passed would be: 11,400 years/ (5,700years/ half-time)= 2 half-time.

Since it undergo 2 half-time, the percentage should be: 100% * (1/2)^2= 25%
