The 4 main influences in behaviorist psychology are Ivan Pavlov, John B. Watson. Edward Lee Thorndike, and B.F. Skinner.

American psychologist Edward Lee Thorndike worked at Teachers College for almost his entire professional life. He helped establish the empirical basis for educational psychology through his research on comparative psychology and the learning process, which gave rise to the connectionism theory. The initial S-R paradigm of behavioural psychology is represented by the learning theory developed by Thorndike.

American psychologist John B. Watson popularised behaviourism as a psychological school and as a scientific theory. Watson promoted this shift in the field of psychology through his 1913 speech, Psychology as the Behaviorist Views It, delivered at Columbia University.

The statement that illustrates how human activities can most directly change the dynamic equilibrium of an ecosystem is water pollution causes a decrease in fish populations in a river.

Human activities, such as industrial and agricultural practices, often release pollutants into bodies of water that can harm aquatic organisms like fish. Pollutants can cause changes in water quality, such as pH levels and oxygen concentrations, which can affect the ability of fish to survive and reproduce.

Additionally, pollutants can accumulate in the tissues of fish, making them unsafe for consumption by humans and other animals that depend on them for food. The decrease in fish populations can also disrupt the food chain, as fish serve as a food source for many other species.

Overall, human activities can have significant impacts on the delicate balance of ecosystems, and it is important to minimize negative impacts by reducing pollution and other harmful practices.

A weak, subthreshold stimulus will result in a small depolarization at the receiving end of the neuron.a weak, subthreshold stimulus will primarily result in a small depolarization at the receiving end of the neuron, but it will not initiate an action potential or trigger neurotransmitter release.

When a neuron receives a stimulus, it can either be strong enough to generate an action potential or be subthreshold, meaning it does not reach the threshold necessary to trigger an action potential.

In the case of a weak, subthreshold stimulus, the neuron will undergo a small depolarization at the receiving end, known as the dendrites and cell body.

The dendrites and cell body of a neuron contain numerous ion channels, including ligand-gated channels and voltage-gated channels.

These channels regulate the movement of ions, such as sodium (Na+), potassium (K+), and chloride (Cl-), which are crucial for generating electrical signals in the neuron.

When a subthreshold stimulus is received, it causes a small influx of positive ions, typically sodium ions, into the neuron through ligand-gated channels.

This influx of positive charge results in a slight depolarization of the neuron's membrane potential.

However, the depolarization does not reach the threshold required to initiate an action potential.

As a result, the subthreshold stimulus is unable to propagate as an action potential along the axon of the neuron.

Instead, the small depolarization may weaken as it travels along the neuron's dendrites and cell body.

This weak signal may not be sufficient to trigger the release of neurotransmitters at the axon terminal, which is necessary for communication between neurons.

B) MPF triggers the cell's passage past the G2 checkpoint into mitosis.

MPF, or Maturation Promoting Factor, is a complex made of cyclin and Cdk (cyclin-dependent kinase) that plays a crucial role in regulating the cell cycle and allowing the cell to proceed from the G2 phase into mitosis. MPF means maturation-promoting factor. It is a protein complex that activates targets necessary to push the cell through the cell cycle.

The three parts of the maturation promoting factor are M cyclin, a cyclin dependent kinase, and a phosphate group which is used to phosphorylate target proteins. During mitosis MPF is deactivated. During anaphase, active MPF activates another protein complex, APC. APC causes the M cyclins to be destroyed, thus deactivating MPF and allowing the new daughter cells to exit mitosis into G1. Maturation-promoting factor is a protein complex made of a cyclin (M cyclin) and a cyclin dependent kinase. The cyclin dependent kinase is activated upon binding to the M cyclin and can phosphorylate targets that promote the cell to move through G2 phase into mitosis, or M phase.

When standing normally, most of your weight is transmitted to the ground by the talus and calcaneus. These two bones play a crucial role in the distribution of body weight and maintaining balance.

The talus, located at the top of the foot, connects with the tibia and fibula, which are the bones in the lower leg. The calcaneus, or the heel bone, is the largest bone in the foot and lies beneath the talus.

Together, the talus and calcaneus form the subtalar joint, which enables the foot to move in a side-to-side motion, also known as inversion and eversion. This movement is essential for walking on uneven surfaces and adjusting to different terrains. The weight-bearing function of these bones allows the foot to support the body's weight and maintain stability when standing or walking.

In contrast, the cuneiforms, cuboid, and other bones in the foot serve different purposes in terms of support, flexibility, and mobility. The cuneiforms and cuboid, as part of the midfoot, are involved in forming the arch of the foot and providing shock absorption. While these bones contribute to the overall function of the foot, they do not primarily transmit the body's weight to the ground like the talus and calcaneus.

Genotype is the combination of alleles that make up an organism’s genetic code. Alleles are variations in a gene that can produce different traits within an organism. In the case of item 1, the genotype is TT. This means that the organism has two copies of the same allele, one from each parent, for a particular trait.

The genotype for item 2 is Tt, which means the organism has one copy of the allele from each parent, in this case one for brown eye color and another for blue eye color. This particular genotype is known as a heterozygous genotype, meaning the organism carries two different alleles for a particular trait.

Finally, item 3 has a genotype of tt, which means the organism has two copies of the same allele, but this time it is for blue eye color. This particular genotype is known as a homozygous genotype, meaning the organism carries two of the same allele for a particular trait.

In conclusion, the genotypes for each numbered item are TT, Tt and tt respectively. These genotypes represent the combination of alleles an organism carries for a particular trait. A genotype of TT means the organism has two copies of the same allele, Tt means the organism has one copy of the allele from each parent and tt means the organism has two copies of the same allele.

Yes, cheetahs have indeed been through a genetic bottleneck, which means that their population size has been significantly reduced at some point in their history, resulting in a loss of genetic diversity. Evidence for this includes the fact that there is very little genetic variability relative to other species of large cat.

Additionally, cheetahs originally came from small areas of Africa, which likely contributed to their reduced genetic diversity. These cats are members of an endangered species, and little natural selection occurs in this species, as their bodies are long, thin, and graceful, which limits their ability to adapt to changing environments.

The part of the nervous system that activates the fight-or-flight response is the sympathetic nervous system.

This system is a component of the autonomic nervous system, which helps regulate involuntary body functions. When faced with a stressful or dangerous situation, the sympathetic nervous system triggers the release of hormones like adrenaline, preparing the body for either fight or flight.

The nervous system is a complex network of specialized cells called neurons, which are responsible for transmitting information throughout the body. It is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).

The CNS consists of the brain and the spinal cord, which are responsible for processing and interpreting sensory information and coordinating motor responses. The brain is also responsible for higher cognitive functions such as learning, memory, and decision-making.

The PNS consists of all the nerves that lie outside the brain and spinal cord and connects them to the rest of the body. It is further divided into the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and sensation, while the autonomic nervous system controls involuntary functions such as heart rate, digestion, and breathing.

The autonomic nervous system is further divided into the sympathetic and parasympathetic nervous systems, which have opposing effects on various bodily functions. The sympathetic nervous system activates the fight-or-flight response, while the parasympathetic nervous system promotes relaxation and rest.

The lateral or occlusal/incisal migration of a prepared tooth without occlusal/incisal and proximal contact can depend on various factors, including the patient's oral habits, the forces applied to the tooth, and the presence of adjacent teeth.

In general, teeth are subject to forces from the surrounding oral structures, such as the muscles, lips, and tongue. These forces, along with the absence of occlusal/incisal and proximal contacts, can potentially lead to tooth migration over time.

However, the exact duration and extent of migration cannot be precisely determined without a specific clinical case and a thorough examination.

Furthermore, the presence of adjacent teeth can play a significant role in stabilizing a prepared tooth. If there are neighboring teeth with proper contact and occlusion, they can help maintain the position of the prepared tooth.

Contractions of the respirator muscles produce changes in air pressure within the bronchial tree and alveoli to bring about ventilation.

The process of ventilation, which involves the movement of air into and out of the lungs, is driven by changes in air pressure within the respiratory system. Contraction and relaxation of the respiratory muscles play a crucial role in generating these pressure changes.

During inhalation, the diaphragm contracts and moves downward while the intercostal muscles contract, causing the ribcage to expand. These muscle contractions increase the volume of the thoracic cavity, leading to a decrease in air pressure within the bronchial tree and alveoli. This decrease in pressure creates a pressure gradient that allows air to flow into the lungs from the higher atmospheric pressure outside.

Conversely, during exhalation, the respiratory muscles relax, and the diaphragm moves upward while the intercostal muscles relax, causing the ribcage to contract. This reduces the volume of the thoracic cavity, increasing the air pressure within the bronchial tree and alveoli. The higher pressure within the lungs compared to the atmospheric pressure outside facilitates the expulsion of air from the lungs.

Thus, the contractions and relaxations of the respiratory muscles are responsible for creating the necessary pressure changes within the bronchial tree and alveoli, enabling ventilation and the exchange of gases in the respiratory system.

If enzymes E1, E2 and E3 are not associated together anymore, there will be no activity in PDH, isocitrate dehydrogenase, or a-ketoglutarate dehydrogenase

In multi-enzyme complexes like the pyruvate dehydrogenase complex (PDH), the isocitrate dehydrogenase (IDH), and the alpha-ketoglutarate dehydrogenase (-KGDH) complex, substrate channelling can take place. Due to the physical association of the enzymes in these complexes, the intermediate products can be transferred from one enzyme to another without dispersing into the bulk solution.

Therefore, substrate channelling cannot take place and the activity of the complex will diminish if the enzymes E1, E2, and E3 are no longer linked together. It is crucial to remember that despite the slower rates, each enzyme in these complexes can still catalyze its specific reaction independently, and the intermediate products will diffuse into the bulk solution to be processed by the following enzyme.
