Answer:
there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling
Explanation:
paracrine:cells that are near one another communicate through the release of chemical messengers
autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface
endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send.
synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.
b:failure of pituitary gland to secrete ADH .caauses diabetes inspidus.
c:located at the kidney.cortex dark in colour and its the outermost.medulla red in colour and lies at the centre.
Ummm ... true , but im pretty sure.
It would be D because would be small and you wouldn't feel it. For answer A, the scientist could feel it. For answer B, you can kind of feel it or feel it. For C, It can definitely feel it. So the answer would be d.
Answer:
Purple colour arises due to the dominant alleles whereas white colour arises due to the recessive alleles.
For the purple colour to arise, even one of the dominant allele will be enough to cause the effect. On the other hand to see the recessive white trait, both the alleles of the gene should be recessive.
To ensure that only white flowers are grown, the farmers need to cross both white flowered plants to get the desired result.
