Answer:
Specie is a group of organisms that can interbreed with one another and produce fertile offspring.
Explanation:
Species Concept that applies to this situation is that a specie is a group of organisms that can interbreed with one another and produce fertile offspring. According to the example of mice, we can conclude that species having different appearance if belongs to the same group so it can interbreed with one another and produce offspring which is fertile and continue its generation.
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.
The bursa that commonly becomes inflamed from overuse of the patellar tendon is the suprapatellar infrapatellar
<h3>
What is superficial infrapatellar?</h3>
Superficial infrapatellar bursitis is a form of knee damage or injury that occurs in the knee. It occurs when the suprapatellar bursa become swollen or inflamed as a result of accumulated fluid around the knee region.
Therefore, The bursa that commonly becomes inflamed from overuse of the patellar tendon is the suprapatellar infrapatellar.
