Bronchoconstriction _____ resistance to air flow and _____ the amount of fresh air the enters the alveoli.
Bronchoconstriction is a narrowing of the air passages in the lungs, which can occur in response to various triggers such as allergens or irritants.
This constriction can increase resistance to air flow, making it harder for air to move in and out of the lungs. As a result, the amount of fresh air that enters the alveoli, the tiny air sacs where oxygen is exchanged with carbon dioxide, can be significantly reduced. This can lead to a range of symptoms, including shortness of breath, wheezing, and coughing. In severe cases, bronchoconstriction can even cause a life-threatening asthma attack. Treatment for bronchoconstriction typically involves medications such as bronchodilators, which work to relax the airway muscles and increase air flow.

One analysis of dolphin meat conducted for the documentary showed a contaminatino of 2000 part per million (ppm). Why is dolpjin meat more likely to contain mercury than other species
Dolphin meat is more likely contaminated and contains higher levels of mercury than other species due to its position in the food chain and the process of biomagnification.
Biomagnification is the process by which the concentration of certain substances, such as pollutants or toxins, increases in organisms as they move up the food chain. Dolphins are apex predators, meaning they feed on other marine animals, many of which have already accumulated mercury in their bodies. As dolphins consume these contaminated animals, the concentration of mercury in their tissues increases. This can lead to bioaccumulation, which is the buildup of toxins in an organism over time and can result in negative health effects.

In the PCR process, once the identified segment of DNA is heated to separate the strands, what substances are then added to facilitate the copying of the segment
In the PCR process, the identified segment of DNA is heated to separate the strands. This denatures the DNA, allowing the strands to be copied. Following denaturation, the primers, which are short lengths of DNA complementary to the DNA sequence, are added.
The primers bind to the ends of the separated strands and initiate the synthesis of new strands of DNA. These newly synthesized strands act as templates for the polymerase enzyme, which uses the primers as a starting point to add complementary nucleotides to the template strands.
This process is repeated multiple times, with each cycle resulting in the duplication of the original DNA segment. This cycle of denaturation, primer annealing, and polymerase enzyme activity is repeated many times, resulting in a large number of copies of the original DNA sequence.

myosin molecules _____ bringing the thin filaments closer to the ___ resulting in contraction of the ____
Myosin molecules [pull/slide] bringing the thin filaments closer to the center of the sarcomere resulting in contraction of the muscle.
Muscle contraction is a complex process that involves the interaction of several proteins, including myosin and actin. Myosin molecules bind to actin molecules in the thin filaments of the muscle cell, forming cross-bridges.
When calcium ions are released from the sarcoplasmic reticulum, they bind to troponin, which causes the tropomyosin to move and expose the binding site on actin. This allows the myosin heads to bind to the actin, causing a conformational change in the myosin molecule.
This change in shape allows the myosin to pull the thin filaments towards the center of the sarcomere, which results in muscle contraction. The sliding of the actin and myosin filaments is a cyclic process that continues until the calcium ions are pumped back into the sarcoplasmic reticulum and the myosin heads are released from the actin.

Many of the biochemical tests we did in lab relied on a pH change to make a conclusion about bacterial growth or identity. Which one of these tests did NOT rely on a pH change
One of the biochemical tests that did not rely on a pH change is the oxidase test. The test is used to identify bacteria that produce cytochrome c oxidase, an enzyme that is involved in the electron transport chain of aerobic respiration.
The test is based on the ability of the enzyme to catalyze the oxidation of a colorless reagent, tetramethyl-p-phenylenediamine dihydrochloride, to a blue-colored compound.
To perform the test, a sample of bacteria is applied to a filter paper, and a small amount of the reagent is added. If the bacteria produce the cytochrome c oxidase enzyme, the reagent will turn blue within a few seconds.
If the bacteria do not produce the enzyme, the reagent will remain colorless. The oxidase test is a rapid and simple method for identifying bacteria that are capable of aerobic respiration.

What steps are required for most B cells to become fully activated and differentiate into plasma cells
Steps required for most B cells require activation through antigen recognition, co-stimulation, and cytokine signals. They then undergo clonal expansion, differentiation into plasma cells, and secretion of antibodies.
B cells are a type of white blood cell that is responsible for producing antibodies, which are essential for fighting infections. In order for B cells to become fully activated and differentiate into plasma cells, several steps are required:
Recognition of antigen: B cells become activated when they recognize a foreign substance (antigen) that matches the specific receptor on their surface.
Internalization and processing of antigen: Once the antigen is recognized, the B cell internalizes it and processes it into small fragments, which are then displayed on the cell surface for recognition by other immune cells.
Helper T cell activation: B cells require activation signals from helper T cells to become fully activated. Helper T cells recognize the antigen fragment presented by the B cell and release cytokines that stimulate the B cell.
Proliferation and differentiation: Once activated, B cells undergo rapid cell division and differentiate into plasma cells, which are specialized cells that produce and secrete large amounts of antibodies specific to the recognized antigen.
Antibody secretion: The plasma cells then secrete antibodies into the bloodstream, where they can bind to and neutralize the invading pathogen.

A good analogy for a cell with an overactive kinase due to a mutation in a proto-oncogene would be a car with a stuck accelerator pedal that causes the car to go faster than intended.
If we think of the cell as a car and mitosis as the process that drives the car, then a cell with a mutation in a proto-oncogene resulting in an overactive kinase would be like a car with a stuck accelerator pedal.
Just as a stuck pedal causes the car to accelerate uncontrollably, an overactive kinase causes the cell to divide uncontrollably, leading to the development of a tumor.
In normal cells, proto-oncogenes are responsible for promoting cell growth and division.
However, when mutations occur in these genes, they can become oncogenes, which promote uncontrolled cell growth and division. One way that oncogenes can become overactive is through the activation of kinases, which are enzymes that regulate cell signaling pathways.
When an oncogene becomes overactive, it can cause the kinase to become stuck in the "on" position, leading to continuous activation of cell signaling pathways and uncontrolled cell growth. This is similar to a stuck accelerator pedal, which causes continuous acceleration of the car.
