The radius of the belt increases and decreases depending on the
flux of charged particles that bombard the magnetic field of the earth around the
region , equator. This increase and decrease is dependent on the solar
activity. Solar storm release charged particles that interact with the magnetic
filed.
The spelling is the only difference
I believe the answer is:
The "spontaneous firing rate" of a neuron refers to <span>its rate of producing action potentials even when it is not stimulated.</span>
After a steroid hormone binds to its intracellular receptor, transcription of specific genes occurs. The activated receptor moves into the nucleus and binds to DNA
<h3>What is steroid hormone and intracellular receptor ?</h3>
Target cells have steroid hormone receptors in their nuclei, cytoplasm, and plasma membranes. They are typically intracellular receptors (often cytoplasmic or nuclear) that start the signalling processes for steroid hormones, which modify the expression of genes over the course of hours to days.
- By attaching to intracellular receptors, steroid hormones control cellular functions by changing the expression of specific nucleotide sequences. Since the majority of steroid receptors in target cells reside in the cytoplasm, they must enter the nucleus to change gene expression.
