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!

In a sample of cells, the DNA content immediately following mitosis is measured and is equal to 10 picograms of DNA per nucleus.
Rasek [7]

Answer:

1. At the end of S phase- 20 pg DNA

2. At the end of G2 phase-  20 Pg DNA

Explanation:

The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.

During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.

In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
