A quadriceps muscle sample from Usain Bolt and compared it to one from a 25-year-old male long-distance runner, and it is seen that there are more fast-twitch fibers and red and white muscle fibers of larger cross-sectional area in Usain Bolt's leg muscles.
What is the distinction between fast-twitch and slow-twitch muscles?Athletes who run fast, such as sprinters, have more fast-twitch muscle, which is called "white muscle," as they need more energy for a short period of time, and as a result, the muscles anaerobically respire. The slow twitch muscle, called "red muscle," is more commonly seen in the long distance runner, such as in the marathon, and these runners need a continuous supply of energy for a long time, so aerobically the muscle respires.
Hence, a quadriceps muscle sample from Usain Bolt was compared to one from a 25-year-old male long-distance runner, and it was seen that there are more fast-twitch muscle fibers and red and white muscle fibers with a larger cross-sectional area in Usain Bolt's leg muscles.

according to the induced fit hypothesis of enzyme catalysis, _____.
Answer:
the binding of the substrate changes the shape of the enzyme's active site
Explanation:
According to the induced fit hypothesis of enzyme catalysis, the shape of the active site of an enzyme changes in response to the binding of a substrate molecule.
What is induced fit hypothesis of enzyme catalysis?The active site, which is the region of the enzyme that interacts with the substrate, adjusts its shape to fit the substrate more snugly. This change in shape enhances the formation of the enzyme-substrate complex, leading to more efficient catalysis and faster reaction rates.
The induced fit hypothesis suggests that the active site is not a rigid structure, but rather, is flexible and dynamic, adapting to the substrate to optimize the reaction.

Explain how Earth's magnetic field is generated.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet

Explanation:
The primary role of the medulla is regulating our involuntary functions that keeps us alive such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.

The respiratory center is medulla oblongata. It is involved in minute to minute control breathing.
What parts are involved in the brain stem ?
Brain stem is made up of pons and the medulla oblongata.
The apneustic and the pnuemotaxic centers of pons work together to just control rate of the breathing. In that the medulla just sends the signals to muscles that just initiate the inspiration and the expiration and just controls the nonrespiratory in the air movement of the reflexes like coughing and sneezing.
The cerebellum is well known to just be the part of neuronal circuitry that is just activated in the respiratory challenges that are such as the hunger for the air but are not been made to be involved in control of the spontaneous and the unobstructed breathing .

What happens when oxygen, carbon dioxide and glucose molecules diffuse across the cell membrane? Explain in your own words
Answer:
Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)
Answer:
the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.
The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.
What is pH?a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.
Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.
The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.

Haversian canals are small channels that run through the bone tissue, and they serve as the highways for blood vessels, nerves, and lymphatic vessels. They distribute blood and other essential nutrients to the bone tissue and allow for the removal of waste products.
These canals are surrounded by concentric layers of bone matrix, known as lamellae, and they help to maintain the structural integrity of the bone. The distribution of blood through the Haversian canals is essential for the health and maintenance of the bone tissue.

Which statement correctly describes how energy is made in photovoltaic cells and how energy is made in photosynthesis?
A.photovoltaic cells can only make energy that does not need light for photosynthesis can only make energy that needs light.
B.photovoltaic cells in photosynthesis can make energy that need light and energy that does not need light. C.photovoltaic cells need light to make energy by photosynthesis to make energy that needs light and energy that does not need light. D.photovoltaic cells can make energy that need light in energy that does not need light for photosynthesis can only make energy that does not need light
Both photosynthesis and photovoltaic cells need light in order to produce energy, though photosynthesis does have a process that can occur in the absence of light, so option C is correct.
Photovoltaic cells are man-made panels that use solar light to create energy. They do this by taking advantage of the natural ability of some materials to absorb the photons in sunlight and use them to release electrons. The release of electrons generates an electric current which produces energy.
Meanwhile, photosynthesis is a naturally occurring process by which plants and a handful of other organisms produce energy. Photosynthesis also requires the presence of sunlight to function. However, photosynthesis also has a dark phase where the chemical reactions continue despite the absence of light. For these reasons, option C is correct whilst the rest are false.
