An action potential triggers the release of synaptic vesicles into the synaptic cleft by _____ channels, allowing _____ ions to

noname [10]

Answer:

1. opening Voltage gated channels

2. Calcium

Explanation:

The signals are transmitted in the neurons in the form of electrical signals and which are transformed into the chemical signals at the synaptic cleft.

The electrical signal is transformed into a chemical signal when the electrical impulse reaches the terminal of the axon and opens the calcium voltage channels. The calcium which is present in a higher amount than inside enter into the terminal and allows fusion of the synaptic vesicle carrying neurotransmitter and the neurotransmitter is released into the synapse.

The neurotransmitter then binds the receptors and initiates the electrical impulse in the postsynaptic neuron.

Thus, opening Voltage gated channels and Calcium is the correct answer.

Explain the logic the woodcutter uses to justify cutting some of the trees for our use.

Y_Kistochka [10]

A woodcutter could justify cutting trees for use say in a pioneering situation whereby the pioneer needs shelter and food so trees could be necessary to say construct a small log cabin and table for eating/preparing food at to ensure the survival of the pioneer.

The ____________ is sometimes called the "funny bone" because of the tingling sensation (pain) one feels if the ____________ is

Alex

Answer:

Ulnar nerve is also called funny bone and feels tingling sensation if humerus is bumbed. Medial epicondyle passes underneath this bony structure.

Explanation:

The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus), ulnar nerve is called funny bone.

The nerve is relatively unprotected at this place.

A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.

Hence, Ulnar nerve is also called funny bone and feels tingling sensation if humerus is bumbed. Medial epicondyle passes underneath this bony structure.

Why might the knoblike proteins on the outer surface of hiv hold a key to the production of a vaccine against aids?

Nataly_w [17]

This is because the GP120 protein of the HIV virus that forms the ‘knob’ is essential for the infection of CD4 cells of the immune system by the virus. The glycoprotein is, therefore, a good target for vaccines especially since the molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.
