The action potential can move only in one direction because the recently depolarized area of the membrane is an absolute refract

Nataly [62]

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.

Organic agriculture is _______.Organic agriculture is _______.a food-growing practice that uses no synthetic fertilizers, insect

Luba_88 [7]

Answer: a food-growing practice that uses no synthetic fertilizers, insecticides, fungicides, or herbicides

Explanation:

Organic agriculture is a process of crops of economic importance. It is an integrated farming system that ensures the sustainability, enhances the fertility of the soil, and that is biological diversity.

It prohibits the use of synthetic pesticide or insecticides, fungicides, synthetic fertilizers, growth hormones, antibiotics, and genetically modified organisms for the growth of crops. It utilizes the fertilizers of organic origin, like manure, compost, bone meal and also supports the crop rotation. It supports the biological pest control and fostering of insect predators.
