Answer: ion-channel-coupled receptors.
Explanation:
These channels are mainly involved with the fast transmission. These receptors are organized into the membrane and regulating or ion-flow channels according to their internal diameter and the predominant electrical charge of their constituent amino acids.
Ion channels can be activated either by membrane potential variation (VOC´S - tension-operated channels), as well as interaction with an agonist (ionotropic receptors), as well as mechanical stimulation or via intracellular agents such as calcium ions, cyclic nucleotides, inositol triphosphate, and G protein. This group includes the nicotinic cholinergic receptor, the GABA receptor, and the glutamate receptor.
The answer is 150,000,000 years (150 million years)
Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm
Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years
The corrrect option is D.
Since the scientist was trying to determine if substance A affect the rate of reaction of X and Y, the best thing to do is to make substance X and Y to react together first, he should then measure the time taken for the reaction to take place. Next, he should make X and Y to react together again, but this time in the presence of A. The time taken for the reaction to occur should be measures. The scientist can now compared the two time measurements and decide if there are difference between them or not.
High-quality cpr is administered when you compress the chest to which depth about 2 inches.

CPR</h3>
Cardiopulmonary resuscitation (CPR) is a life-saving emergency technique that involves giving someone who is having a cardiac arrest chest compressions and sometimes artificial ventilation in an effort to keep their brain functioning normally until additional steps are taken to bring back their breathing and spontaneous blood circulation. In people who are unresponsive and not breathing or who are breathing abnormally, such as experiencing agonal respirations, it is advised.
Adults who need CPR must perform chest compressions between the depths of 5 cm (2.0 in) and 6 cm (2.4 in) per minute, at a minimum.
By utilizing a machine that forces air into the subject's lungs or by exhaling into the subject's mouth or nose (mouth-to-mouth resuscitation), the rescuer can also offer artificial ventilation (mechanical ventilation).

Hello! Good morning!
Answer-
First of all, you need to know what a genotype is. A genotype is the genetic constitution of an individual organism. Which means, aA, can not be a genotype.
Hope this helps! Have a great day Sir/Ma'am.
