description most closely resembles how stereocilia perform. In hair cells, bending causes depolarization or hyperpolarization.
Depolarization is the process of bringing a cell's barrier potential to a higher positive value. Repolarization is the process through which the membrane potential shifts from a high to a net negative. The inner membrane has become less negative after depolarization. When voltage-gated sodium channels open, sodium ions ions rush into a neuron, causing depolarization. The potassium ion channels open and the na+ channels shut to cause repolarization. Depolarization is a positive change from the resting potential achieved by increased permeability to an ion with a Nernst potential above the RBP.

in the sliding-filament model of muscle contraction, what component of the muscle cell is sliding?
In the sliding-filament model of muscle contraction, the thin filaments composed of actin are sliding past the thick filaments composed of myosin within the muscle cell.
This sliding of filaments results in the shortening of the sarcomeres and ultimately the muscle contraction.
Movement and bodily functions are made possible by the fundamental physiological process of muscle contraction. It entails the contraction of muscle fibres as a result of nerve impulses. The interaction between actin and myosin, two proteins found in muscle cells, is the first step in the process, which starts with the release of calcium ions. Myosin heads experience a power stroke as they bind to actin, drawing the actin filaments together and causing the muscle to contract. Actin and myosin filaments slide throughout this repeating cycle of attachment and detachment, which is powered by ATP and results in force production and muscle contractions.

which is more resistant to fatigue, cardiac or skeletal muscle? what is the anatomical basis for this difference and why is it important?
Cardiac muscle cells contain many mitochondria that provide the necessary energy for the cell in the form of adenosine triphosphate (ATP), making them highly resistant to fatigue.
Because cardiac muscle has more mitochondria than skeletal muscle, it is resistant to fatigue. It is up to 35 percent mitochondria, compared to just 1-2 percent in skeletal muscle. Mitochondria are necessary for the generation of ATP, which supplies cells with energy. The rapid, involuntary contraction and relaxation of the heart muscle are vital to pumping blood throughout the cardiovascular system. To achieve this, the structure of the heart muscle has distinct characteristics that allow it to contract in a coordinated manner and resist fatigue. This is mainly because the heart is made of cardiac muscle, which consists of special cells called cardiomyocytes. Unlike other muscle cells in the body, cardiomyocytes are highly resistant to fatigue.

Explain why every cell that is produced from the genetically modified bacterium
will be able to produce insulin.
Answer:
Recombinant DNA is technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene. Scientists build the human insulin gene in the laboratory. Then they remove a loop of bacterial DNA known as a plasmid and insert the human insulin gene into the plasmid. Researchers return the plasmid to the bacteria and put the “recombinant” bacteria in large fermentation tanks. There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria and purify the substance for use as a medicine for people.

What are capillaries?
Select one:
a.
blood cells that fight infection
b.
vessels through which nutrient and gas exchange take place
c.
chambers of the heart that pump blood throughout the body
d.
the liquid part of the blood that transports hormones
b. Capillaries are vessels through which nutrient and gas exchange take place.
Capillaries are the smallest blood vessels in the body and are responsible for facilitating the exchange of nutrients, gases, and waste products between the bloodstream and surrounding tissues. They connect the arterioles (small branches of arteries) and venules (small branches of veins).
Capillaries have thin and permeable walls, consisting of a single layer of endothelial cells. This structure allows for the exchange of substances between the blood and surrounding tissues. Oxygen and nutrients diffuse out of the capillaries into the tissues, while carbon dioxide and waste products from cellular metabolism diffuse into the capillaries to be carried away.
The extensive network of capillaries ensures that every cell in the body is located in close proximity to a capillary, allowing for efficient exchange of substances. This exchange includes the delivery of oxygen and nutrients to the cells, as well as the removal of carbon dioxide and waste products.
While blood cells, such as red blood cells and white blood cells, are present in the capillaries, they are not the defining characteristic of capillaries. Instead, capillaries are primarily associated with facilitating the exchange of substances between the bloodstream and the surrounding tissues.
Therefore, option b is the correct answer as it accurately describes the role of capillaries in facilitating nutrient and gas exchange.

Which features demonstrates cold adaptation among neandertals?
Neanderthals demonstrated several features that indicate cold adaptation, including robust body structure, large nasal cavities, and specialized cranial features.
Neanderthals, an extinct species of humans, inhabited regions with cold climates during the Pleistocene era. Their physical features indicate adaptations to survive in such environments. Firstly, Neanderthals had a robust body structure with stocky builds and shorter limbs, which helped them retain body heat in colder conditions. This body shape reduced the surface area-to-volume ratio, minimizing heat loss.
Secondly, Neanderthals had large nasal cavities, which are believed to have been advantageous in cold environments. The increased nasal volume allowed for the warming and humidification of cold, dry air before it reached the lungs, reducing the risk of respiratory issues caused by inhaling cold air.
Lastly, Neanderthals possessed specialized cranial features, such as a prominent brow ridge and a low, elongated skull. These features may have helped protect their faces and brains from the harsh elements, including cold temperatures and physical stress.
Together, these adaptations suggest that Neanderthals were well-suited to survive in cold climates by minimizing heat loss, protecting their respiratory systems, and providing physical protection. These cold adaptations were likely beneficial for their survival in the challenging environments they inhabited during their existence.
