Hello.
00:01
So let's answer now the question.
00:04
Okay, so there are many questions to this problem.
00:06
Okay, so for number one, our answer here is we have the action potential.
00:19
So it is the correct answer because neurons send both information as well as instructions to the brain and the body through an electrochemical signals known as action potentials.
00:33
So the neurons then release chemical messengers or what we called neurotransmitters to help to trigger or this help these neurotransmitters help trigger the action potentials within the body and spread the signal all over okay so this is for number one okay for number two our answer here is we have the free nerve endings so the free nerve endings mostly are present in skin cornea and even in our digestive track or elementary canal and also in connective tissues also called nociceceptors because of a high threshold for temperature mechanical or specific chemicals and respond and respond when the intensity of above mentioned becomes dangers to tissue or body again so our answer for number two we have nerve endings, free nerve endings.
01:49
Okay.
01:50
And for number three, okay, our answer here is we have membrane depolymerization.
02:12
So membrane depolymerization is the correct option because the signaling molecules or the odorant molecules binds to the olfactory receptor, which activate the g alpha gtp, then it activates or stimulates the adenolate cyclase and adenolate cyclase then activates the camp, which then opens the sodium channels which causes membrane depolymerization.
02:42
Okay, so this is our answer.
02:44
And for number four, the lateral line is located on fish.
02:50
So our answer is fish.
02:53
So this lateral line helps the fish to detect prey and to swim in synchrony.
02:58
With their group or with their school.
03:02
So fish has a lateral line.
03:14
Okay, let's go for number five.
03:17
Oops, it's for number five, okay, sorry.
03:21
So for number five, there's no number four.
03:23
Okay, for number five, okay, our answer here is we have fish...
