PLEASE HELP ASAP!! How neurotransmitters carry nerve impulses across the synaptic cleft

2 answers:

7 0

Explanation: Neurotransmitters like to travel across the synapse between the axon and the dendrite of the next neuron. They then attach to the membrane of the dendrite. This connection makes it possible for the nerve impulse to travel through the receiving neuron.

Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron

Another way of thinking is

Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine)

Hope this helps =)

IF A CUBE IS 1CM ON A SIDE, CALCULATE ITS SURFACE AREA. HINT WRITE 2 points

frosja888 [35]

Answer:

Surface area of the cube = 6cm²

Volume of the cube = 1cm³

Explanation:

The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:

S.A = 6 × a²

That is; a² + a² + a² + a² + a² + a²

Where;

a = length of a side of a cube

a² = area of one side of a cube

Note that, a cube has 6 faces

According to this question, a cube has a length of 1cm on each side.

Hence, S.A = 6 × 1²

S.A = 6 × 1

S.A = 6cm²

Volume of the cube can be calculated using the formula: a³

Where a = 1

Volume = 1 × 1 × 1

Volume = 1cm³

Which substance on the plasma membrane helps identify chemical signals from outside the cell?

nikdorinn [45]

Answer:

The correct answer is carbohydrate chain.

Explanation:

Plasma membrane contain three types of protein a peripheral protein b transmembrane protein and c GPI anchored protein.

Some membrane protein basically peripheral proteins contain oligosaccharide chain arranged towards the extracellular region of the plasma membrane with respect to the surface of that glycoprotein.

The oligosaccharide chain of glycoprotein play an important role in to identify signals from outside the cell.These signals may include the entry of virus particles inside our body,protein targeting etc.

The kidneys carry countless ova which are released to outside through the oviducts. </span><span>In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.</span>
