Answer:
"Growers using organic soils will never concern themselves with supplying oxygen to their plants; however, hydroponic growers like me must be well versed in the science of dissolved oxygen (from here on out called DO). While most crops seem to prefer about 9 PPM DO, some crops like lettuce have demonstrated little to no difference in fresh weight or dry weight when grown in DO levels ranging …"
Explanation:
<span>During the luteal phase of the ovarian cycle, progesterone secretion peaks and estrogen levels decrease. along with these changes, there is a corresponding increase in a woman's basal body temperature. In this phenomenon, i</span>t is not the increase in progesterone, but the decrease in estrogen that may signal an increase in overall body temperature. This is because the decrease in estrogen reduces the negative feedback signal to the hypothalamus, the thermoregulator for the body. The result is an increase in overall basal body temperature.
Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
