Answer:
Explanation:
During exhalation, the diaphragm also relaxes, moving higher into the thoracic cavity. This increases the pressure within the thoracic cavity relative to the environment. Air rushes out of the lungs due to the pressure gradient between the thoracic cavity and the atmosphere.
Answer:
This question lacks options, the options are:
a. Presynaptic; Ca2+ ions
b. Postsynaptic; Ca2+ ions.
c. postsynaptic; neurotransmitters
d. presynaptic; neurotransmitters
e. dendritic; neurotransmitters
The correct answer is d. Tetrahydrocannabinol, the active ingredient in marijuana, binds to receptors located in the <u>presynaptic</u> terminals of certain brain neurons. It lowers the likelihood that these neurons will release <u>neurotransmitters</u>
.
Explanation:
Tetrahydrocannabinol is the most abundant cannabinoid in most cannabis varieties and has the most potent psychoactive effect. Conventional neurotransmitters are water-soluble substances stored in small vesicles at the thin ends of the axon (presynaptic terminals). When a neuron generates an impulse by sending an electrical signal along the axon to the presynaptic terminals, the neurotransmitters are released from the vesicles, diffuse through a narrow intercellular space (synaptic cleft) and interact with the receptors on the surface of the recipient neuron (postsynaptic neuron). Cannabinoids cause a decrease in the release of neurotransmitters from the presynaptic terminal through the inhibition of Ca++ channels. This signaling is mediated by the βγ subunit of the G protein. The βγ subunit of the G protein inhibits the Ca channels of type N and P / Q, which are the majority in presynaptic neurons.
B the lower the volume of water in take the lower the volume of urine produced
<h2>Answer:</h2>
Correct order from least greatest mass to greatest mass:
- Terrestrial
- ice giants
- Ice dwarfs
- Gas giants
<h3>Explanation:</h3>
The above given list contains the names of different planets depending upon their compositional characteristics. According to this list gas giants are heavier and then ice dwarfs and then ice giants.
Terrestrial which means planet earth is top on the list, which is lighter in weight than other planets.
Glycogen is the human counterpart of the plant starch. So humans store the energy from consumed starch as glycogen.
