â Blood viscosity â Total blood vessel length â Blood vessel diameter Resistance â¢ Factors that remain relatively constant: â Blood viscosity â¢ The stickiness of blood due to formed elements and plasma proteins â¢ Increased viscosity = increased resistance â Blood vessel length â¢ Longer vessel = greater resistance encountered
Jasmonic acid (JA) is derived from the fatty acid linolenic acid. It is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
Upon receiving the electronic signal, faraway leaf tissues produced a chemical called jasmonate.. Botanists recognize this hormone as a key role player in several plant processes, specifically when it comes to initiating one of a plant's many defensive schemes.
