Answer:
What causes the second voltage-gated Na+ to open is the charge changes caused by the flow of ions through the first channel.
Explanation:
The second channel is a voltage-gated Na+ channel, we know that voltage-gated channels open their gates when there is a change in the voltage of the cell, by opening the first ion channel, there is a rush of ions to the inside of the cell that modifies the cell's voltage due to the new charges. The second channel is affected by this, and as a consequence, it opens its gates.
Answer:
C)
Explanation:
The correct answer is outbreak because herpes symptoms are ones referring to the outbreak of small sores that are appearing first. Those small sores are forming ulcers and scabs which are causing pain and itching.
A is an incorrect answer because herpes is not considered an infectious disease in a community that is happening at one particular time.
B is an incorrect answer because herpes symptoms do not develop so fast that we can call it an eruption.
D is an incorrect answer because those symptoms are not showing without a cause such as a low immune system.
Answer:
Complementary angles
Explanation:
Complementary angles. Because ∠EFB = 90° ⇒ ∠EFA = 90°
∠AFC + ∠EFC = 90°.
Hence, the correct answer is complementary angles.
