Diffusion refers to the process by which molecules move from a region of high concentration to a region of low concentration. A few factors influence the rate of diffusion.

These factors are:

Temperature results in an increase in molecular motion, which raises the probability of molecular collision.The magnitude of the concentration gradient: A significant concentration gradient results in a greater rate of diffusion.

The greater the difference between the two areas' concentration, the greater the diffusion rate. Molecular weight: The lighter the molecule, the greater its rate of diffusion. Larger molecules move at a slower rate because their mass slows them down.

Surface area: As the surface area increases, so does the rate of diffusion. This is due to the greater space available for the molecules to diffuse.Viscosity: An increase in viscosity would decrease the rate of diffusion. Molecules find it challenging to move through a more viscous medium.

62. The process that does NOT require calcium is repolarization of a neuron's plasma membrane during action potentials.

a. Repolarization is the stage of an action potential in which the membrane potential returns to its resting state by either potassium ions flowing out or chloride ions flowing in. The reason for this is that it does not need calcium because the movement of potassium ions is regulated by potassium channels.

b. Exocytosis of neurotransmitters from axon terminals requires calcium ions to enter the axon terminal from the extracellular fluid, leading to fusion of vesicles with the presynaptic membrane and the release of neurotransmitters.

c. Smooth muscle contraction requires calcium ions to bind with calmodulin, which then activates myosin light-chain kinase, resulting in the phosphorylation of myosin.

d. Gland secretions are stimulated by various factors, including calcium ions that play a role in the release of certain hormones.

e. Exocytosis of neurotransmitters from varicosities in the ANS requires calcium ions to enter the varicosity, leading to the fusion of vesicles with the plasma membrane.

63. Sensory receptors are specialized structures that detect a specific form of energy in the external or internal environment and transduce it into a graded potential. Photoreceptors are sensory receptors in the retina that detect light energy, whereas nociceptors are sensory receptors in the skin that detect pain. Rods are photoreceptor cells in the retina that detect light under low-light conditions. The primary cortex is the region of the brain that receives and processes sensory input from sensory receptors.

64. Dual innervation is the concept that most viscera are innervated by both the sympathetic and parasympathetic divisions of the autonomic nervous system. These two divisions have opposing effects on the same organ, allowing for fine control of the organ's activity. Some examples include the heart, which is innervated by both the sympathetic and parasympathetic divisions, and the gastrointestinal tract, which is innervated by both divisions as well.

a. Most viscera are regulated by both the endocrine system and autonomic nervous system,

b. Most viscera only receive innervation by one of the two divisions of the autonomic nervous system,

c. Most viscera are innervated by both the somatic motor division and the autonomic nervous system.

e. None of the other answers are correct are incorrect.

65. The resting membrane potential is established mainly from the diffusion of potassium ions through leak channels. The resting membrane potential is the voltage difference between the inside and outside of a cell when it is not being stimulated. This potential is established by the movement of ions through ion channels in the plasma membrane. Potassium ions are the most important ions involved in generating the resting membrane potential because the cell is more permeable to potassium than any other ion.

a. Sodium ions through voltage-gated channels,

b. Potassium ions through voltage-gated channels,

c. Sodium ions through leak channels,

d. Calcium ions through leak channels, and

e. Calcium ions through voltage-gated channels are incorrect because only a few ions can diffuse through leak channels, and voltage-gated channels are activated by changes in membrane potential, not by concentration gradients.

66. The rapid depolarization phase of an action potential is due to the movement of sodium ions through voltage-gated channels. The rapid depolarization phase of an action potential is characterized by a rapid increase in membrane potential due to the influx of positively charged ions into the cell. This influx of ions is mainly due to the opening of voltage-gated sodium channels in the plasma membrane. Chloride ions, potassium ions, and sodium ions through leak channels are not responsible for the rapid depolarization phase of an action potential.

67. Neurotransmitters (NT) bind to receptors on postsynaptic neurons and cause ion channels to open or close. This affects the postsynaptic neuron because NT binding changes the membrane potential and creates either a depolarizing or hyperpolarizing graded potential. The effect of NT on the postsynaptic neuron depends on the type of receptor it binds to. Some receptors are ligand-gated ion channels that directly open or close ion channels, while others are G protein-coupled receptors that activate intracellular signaling pathways.

. Tryptophan acts as a corepressor that inactivates the repressor protein and prevents RNA polymerase from transcribing the structural genes, inhibiting the production of tryptophan.


- The trp operon is a set of genes in bacteria responsible for producing enzymes that synthesize the amino acid tryptophan.
- The trp operon is regulated by a repressor protein that binds to the operator region of the DNA and prevents RNA polymerase from transcribing the structural genes.
- When tryptophan levels are high, trp molecules bind to the repressor protein and activate it as a corepressor.
- The activated repressor protein then binds more tightly to the operator region, preventing RNA polymerase from transcribing the structural genes and inhibiting the production of tryptophan.
- When tryptophan levels are low, there are no trp molecules to activate the repressor protein. This allows RNA polymerase to bind to the promoter and transcribe the structural genes, leading to the production of tryptophan.
- The enzymes produced by the trp operon are repressible enzymes, which means that they are normally active and their production is inhibited by the end product of the pathway (tryptophan).


In summary, the trp operon is a regulatory system that allows bacteria to produce the amino acid tryptophan only when it is needed. Tryptophan acts as a corepressor that inactivates the repressor protein and prevents RNA polymerase from transcribing the structural genes, inhibiting the production of tryptophan.

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.

A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.

Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.

Class 1: Double-stranded DNA viruses.

This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.

Class 2: Single-stranded DNA viruses.

Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.

Class 3: Double-stranded RNA viruses.

Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.

Class 4: Single-stranded RNA viruses (positive sense).

Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.

Class 5: Single-stranded RNA viruses (negative sense).

Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.

Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.

Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.

Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.

Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.

Captive breeding and release programs, widely used to supplement populations of declining species, minimize juvenile mortality to achieve rapid population growth. However, raising animals in benign environments may promote traits that are adaptive in captivity but maladaptive in nature. In chinook salmon, hatchery rearing relaxes natural selection favoring large eggs, allowing fecundity selection to drive exceptionally rapid evolution of small eggs. Trends toward small eggs are also evident in natural populations heavily supplemented by hatcheries, but not in minimally supplemented populations. Unintentional selection in captivity can lead to rapid changes in critical life-history traits that may reduce the success of supplementation or reintroduction programs.

The arrangement of abdominal muscles provides them with effective protection and containment of the abdominal viscera.

The abdominal muscles, including the rectus abdominis, external obliques, internal obliques, and transversus abdominis, play a crucial role in protecting and containing the abdominal viscera. Their arrangement and structure contribute to their effectiveness in performing this function.

The abdominal muscles are layered and arranged in such a way that they form a strong and flexible abdominal wall. The rectus abdominis muscles, commonly known as the "six-pack" muscles, run vertically down the front of the abdomen and provide stability and support. The external obliques, internal obliques, and transversus abdominis muscles wrap around the sides of the abdomen in multiple layers, forming a protective sheath. This layered arrangement adds strength and rigidity to the abdominal wall, making it resistant to external forces and impacts.

Additionally, the abdominal muscles are interconnected with connective tissue called fascia. This fascia forms a network of supportive structures that hold the abdominal organs in place and prevent them from shifting or herniating. The fascia acts as a natural barrier, providing further protection and containment of the abdominal viscera.

In conclusion, the arrangement of the abdominal muscles, with their layered structure and interconnected fascia, makes them well-suited for their job of protecting and containing the abdominal viscera. They provide stability, strength, and flexibility to the abdominal wall, ensuring the organs are safeguarded and properly positioned within the abdominal cavity.
