Summation and integration of impulses at a synapse:Summation of impulses is the additive effect of excitatory and inhibitory synaptic inputs. The summation of signals can either excite or inhibit the neuron's firing.

The summation of impulses occurs at the synapse, which is the junction between two neurons.Integration of impulses refers to the process by which a neuron combines incoming signals from different sources and decides whether or not to fire. In order to integrate the signals, the neuron must add up all the excitatory and inhibitory inputs, taking into account their amplitude, duration, and location.One-way transmission of an impulse across a synapse:Transmission of an impulse across a synapse is "one-way" because of the presence of synaptic vesicles.

These are sacs containing neurotransmitters that are released by the presynaptic neuron into the synaptic cleft, a narrow space between the two neurons. Once the neurotransmitter is released, it diffuses across the synaptic cleft and binds to receptors on the postsynaptic neuron, causing the ion channels to open and allowing the impulse to travel further. However, the postsynaptic neuron cannot send a signal back to the presynaptic neuron as it does not have the necessary machinery to release neurotransmitters and cannot stimulate the presynaptic neuron.Events between the time a nerve impulse reaches the end of an axon and the release of neurotransmitters:The nerve impulse reaches the end of the axon and triggers the influx of calcium ions into the presynaptic neuron.

This influx of calcium ions causes the synaptic vesicles to fuse with the presynaptic membrane and release the neurotransmitter into the synaptic cleft. The neurotransmitter diffuses across the cleft and binds to receptors on the postsynaptic neuron, causing the ion channels to open and allowing the impulse to travel further. Once the neurotransmitter has bound to the receptor, it is either removed from the synaptic cleft by reuptake into the presynaptic neuron or degraded by enzymes.

For DNA viruses, the virus cycle occurs in the host cell nucleus. Whereas the virus cycle for RNA viruses occurs in the host cell cytoplasm.

DNA viruses, such as herpesviruses and adenoviruses, replicate their genetic material in the nucleus of the host cell. The virus enters the host cell and releases its DNA genome. The viral DNA then utilizes the host cell's machinery to transcribe and replicate itself. This involves the synthesis of viral mRNA and the production of viral proteins. The replicated DNA is packaged into new virus particles, which are then released from the host cell to infect other cells.

On the other hand, RNA viruses, including influenza viruses and coronaviruses, carry their genetic material in the form of RNA. These viruses replicate their RNA genomes in the cytoplasm of the host cell. After entering the cell, the RNA virus uses its RNA genome as a template to synthesize viral proteins.

Most of the blood enters the ventricle during atrial systole. The option a) aligns with the answer.

Atrial systole is the process in which the atria of the heart are contracting to increase the volume of blood present in the ventricles. The sinoatrial (SA) node, which is the heart's natural pacemaker, sends electrical impulses to the heart's atria. The impulses travel along specific conduction pathways and cause the atria to contract. Blood is then pumped into the ventricles via open atrioventricular valves.

The process of atrial systole is followed by ventricular systole.What is Ventricular Systole?The ventricles, which are the lower chambers of the heart, contract during ventricular systole, pushing blood out of the heart into the aorta and pulmonary artery. The heart is divided into four chambers, with the two upper chambers referred to as atria and the two lower chambers referred to as ventricles.

Blood flows from the atria to the ventricles during ventricular diastole, which is the period of time when the heart is relaxed and not contracting. When the ventricles contract during systole, the atrioventricular valves close, preventing backflow of blood from the ventricles to the atria.
