Option d is Correct. When comparing different types of pain perception, C fibers, unmyelinated, persistent pain is accurate.

One of these categories, the C-type fibers, are unmyelinated fibers that play a role in the afferent transmission of warmth, burning pain, and itch from the periphery to synapse. These fibers are most commonly found in lamina I and II of the dorsal spinal horn.

In contrast to Groups A and B, which are myelinated, the C group fibers are unmyelinated, tiny in diameter, and have a poor conduction velocity. Postganglionic fibers in the autonomic nervous system (ANS) and nerve fibers at the dorsal roots are examples of group C fibers (IV fiber). These fibers transmit sensory data. The brain interprets the pain experience and sends a fast motor reaction in an effort to stop the painful action.

Viral (+) strand RNA is produced with a cap

Viral envelope proteins move to the plasma membrane ,Progeny viruses are produced, Influenza replication is the process by which the influenza virus reproduces itself by hijacking the cellular machinery of a host cell. The virus uses its surface protein, hemagglutinin, to bind to host cell receptors and enter the cell. Once inside, the virus uncoats and releases its genetic material, which is in the form of negative-sense RNA. The viral RNA is then transcribed into positive-sense RNA, which serves as a template for the production of viral proteins and more viral RNA.

The objects are in thermal equilibrium when they have the same temperature.

The correct answer is D.

Thermal equilibrium is a state in which two or more objects are at the same temperature and there is no net transfer of heat between them. Heat is a form of energy that can be transferred from one object to another due to a temperature difference. When two objects are in contact, heat will flow from the hotter object to the cooler object until they reach the same temperature.

In thermal equilibrium, there is no net transfer of heat between the objects, and their temperatures remain constant. If the objects' temperatures are changing, then they are not in thermal equilibrium. Similarly, the objects do not need to be touching each other to be in thermal equilibrium; they could be separated by some distance and still have the same temperature.

To prepare 750 ml of 3 M sulfuric acid, you would need (3 x 750) / 18 = 225 ml of concentrated (18 M) sulfuric acid.

To determine the amount of concentrated sulfuric acid required to prepare 750 ml of 3 M sulfuric acid, we need to use the formula: M1 x V1 = M2 x V2, where M1 is the concentration of the concentrated sulfuric acid (18 M), M2 is the desired concentration (3 M), V1 is the volume of concentrated sulfuric acid, and V2 is the desired volume (750 ml).

Solving for V1, we get: V1 = M2 x V2 / M1 = 3 x 750 / 18 = 150 ml. So, 150 ml of concentrated (18 M) sulfuric acid is required to prepare 750 ml of 3 M sulfuric acid. It is important to handle concentrated sulfuric acid with caution and to follow proper safety protocols when working with it.

HWE is a principle which states that the genetic equilibrium of a population remains constant from one generation to another, until disturbed by some external factor like mutation, gene flow, etc.

Migration of genes is the transfer of genetic composition from one population to another. This is also called the gene flow. Gene flow can be due to one individual from a population going to another one which then causes vertical transfer after mating.
