The salt in the seawater dehydrated the sailor because his body could not absorb the amount of salt in the seawater.
It goes like this: “if I give a plant an unlimited amount of sunlight, then the plant will grow to the largest size possible”. I hope you will let me know if this is the case or not =^-^=
Because steroid hormones bind to intracellular receptors and can regulate gene expression (turn genes on or off).
Explanation: Receptors located in the nucleus are called intracellular receptors (unlike the transmembrane receptor which is located on the membrane). Normally, intracellular receptor ligands are small hydrophobic molecules, as they must cross the plasma membrane to reach their receptors. For example, hydrophobic steroid hormones such as estrogen or testosterone are ligands for intracellular receptors.
Intracellular receptors have DNA-binding activity, which means they can bind to specific DNA sequences and regulate their gene expression (eg, transcription).
So they need time to do their job.
