<h3>ANSWER: </h3>

Norepinephrine

<h3>EXPLANATION:</h3>

Norepinephrine is an organic chemical which is also known as noradrenaline or stress hormone. It belongs to the catecholamine family that functions in the brain and body as both hormone and neurotransmitter. It is a chemical which is mostly released by the sympathetic nervous system at times of stress.

Norepinephrine is a major excitatory neurotransmitter that regulates the release of dopamine, it is a substance used mainly by the sympathetic or orthosympathetic nervous system, it is part of the neurotransmitters, its function is to transmit messages through the nerves to the different components of the body through numerous physiological processes.

Which synapse(s) are specifically responsible for the sensitization of the withdrawal response?

qaws [65]

The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.

The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.

By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.

Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.

Which of the following scenarios is an example of temporal isolation?

DedPeter [7]

Answer:

B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.

Explanation:

Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.

Many plant cells have a single, large _________ __________ that is filled with fluid.

vlada-n [284]

Letter A is the answer. Almost all plant cells have single large central vacuole. These large central vacuoles of the plant cells are filled with water and can take over 80% of its cell volume. This is surrounded by a single membrane called tonoplast. The role of the central vacuole is maintaining the plant cell's pressure.

The blood in an artery flows faster and at higher pressure. Explain why.

Elenna [48]

Answer:

The blood in an artery flows faster and at higher pressure. Its because pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.Moreover the arteries have thicker smooth muscle and connective tissue than the veins to accommodate the higher pressure and speed of freshly pumped blood. The veins are thinner walled as the pressure and rate of flow are much lower.
