The presence of ribosomes on the rough ER suggests that the proteins are synthesized as well as modified there as opposed to the smooth ER.
Ribosomes are responsible for the synthesis of proteins from the amino acids. They translate each codon on the RNA template and match it with the appropriate amino acid to make a protein. This process is known as translation. Ribosomes can be found free in the cytosol or attached to the surface of the endoplasmic reticulum. When the ribosomes are bound to it, it is known as the rough ER and without it, it is called smooth ER. Smooth ER performs different functions like the synthesis of lipids and phospholipids. Since it does not have ribosomes, it cannot synthesize proteins.

Why is the selective permeability of the plasma membrane essential for normal cell function?.
The selective permeability of the membrane is essential for the normal functioning of the cell because it maintains the internal order and functioning of the cell. Water, ions, glucose, and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity.
Along with this, the entry and exit of signaling molecules in the cell are also needed to be regulated. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing, and rate of movement of these molecules.
Plasma Membrane: It is a membrane that encloses all the constituents of the cell and separates them from the exterior environment. It is mainly made up of lipids and proteins.

Increase in arterial blood pressure will result in an increased rate of impulse firing.
When baroreceptors in your carotid arteries detect elevated blood pressure, it activates the baroreceptors resulting in increased firing of action potentials with the rapidity proportional to the degree of mechanical stretch.
Stretching of the baroreceptors as a result of increased blood pressure causes an increase in the activity of the vagal nerve by projection to the nucleus ambiguus. It also causes inhibition of the sympathetic outflow and ultimately leads to decreased heart rate and blood pressure.

Listeners appear to comprehend the meaning of the sounds made by primates in response to particular occurrences, such as the discovery of a particular predator. Although this form of communication and human referential words appear to be similar on the surface, the mental processes that underpin them may be extremely different.

The majority of neurotransmitters migrate across the synaptic gap and latch onto receptor sites of the receiving neuron's:
Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.
What is a synapse?
Neurons are cells that communicate with each other through the transmition of nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.
Dendrites are the structures that receive chemical messages from the other cells.
The correct option is D. Dendrites.
