Answer:
you agree with Al
Explanation:
Al's answer is most accurate because plants have chlorophyll, which they use to trap rays of sunlight to make their own food (photosynthesize) and Plants have mitochondria and can perform cellular respiration.
Answer: Na+ channels are closed
Explanation:
The refractory period describes a period between the initiation of an action potential (where Na+ channels are active/open), and immediately after the action potential’s peak. In the absolute refractory period, action potentials cannot be generated, as Na+ channels are in an inactive or closed state, they usually take around one or two minutes.
After the absolute refractory period the relative refractory period (RRP) occurs. During the RRP, it is hard to send another action potential. Na+ channels are once again open, but the cell remains hyperpolarized- its membrane potential, remains negative. Recovery from inactivation is voltage and time-dependent; Action potentials would require an influx of more positively charged ions. These must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Answer:
Science is the study of nature around us.
I would say that the parameter or symptom most important for the diagnosis of heat stroke would be the giddiness. Personally, I was kneeling down working in the heat a few years ago at a job and when I stood up I blacked out and fell to the ground helplessly and the first aid attendant figured it may have been due to heat stroke.
