A) High frequency waves (high notes) depress the basilar membrane closest to the cochlear's distal end.
The basilar membrane is a stiff structural element within the cochlea of the inner ear that separates the scala media and scala tympani, two liquid-filled tubes that run along the coil of the cochlea. In response to incoming sound waves, which are converted to traveling waves on the basilar membrane, the basilar membrane moves up and down.
The basilar membrane is a pseudo-resonant structure that varies in width and stiffness, much like the strings on an instrument. However, unlike the parallel strings of a guitar, the basilar membrane is a single structure with varying width, stiffness, mass, damping, and duct dimensions along its length.

how does plant synthesise carbohydrate?
Answer:
The plants synthesize their carbohydrates from water, carbon dioxide and sunlight with the help of green pigment known as chlorophyll. This process of synthesis of food by the green plants from water, carbon dioxide and sunlight with the help of green pigment known as chlorophyll is called photosynthesis.
Plant synthesize carbohydrate by the process of photosynthesis.
Photosynthesis is a process by which green plants are some other organisms use sunlight to synthesize nutrients from carbon dioxide and water.
The carbohydrates are made of carbon, hydrogen and oxygen. These are used to synthesize other components of food such as proteins and fats.
Carbohydrates are formed in green plants by photosynthesis, which is the chemical combination, or fixation, of carbon dioxide and water by utilization of energy from the absorption of visible light.
To store carbohydrates, plants take the glucose formed during photosynthesis and combine the carbohydrate with oxygen- a process called respiration- to release energy.

Why don t these enzymes digest the stomach and small intestine which are partially composed of protein?.
Enzymes have a difficult time working on the live protein chains that line your mouth, stomach, and intestine. Because the live protein chains are tightly coiled, enzymes cannot come into contact with them.
Enzymes are proteins that act as catalysts, increasing the rate of chemical reactions without changing the overall process.
The stomach, pancreas, and small intestine produce protease. The majority of chemical reactions take place in the stomach and small intestine. Pepsin is the primary digestive enzyme that attacks proteins in the stomach.
Pepsin is released in an inactive form, or zymogen form, by specific cells within the gastric lining known as chief cells. In this way, the stomach prevents the auto-digestion of protective proteins in the digestive tract lining.

the timing of the cell cycle in eukaryotic cells is believed to be controlled by a group of closely related proteins known as
The cell cycle in eukaryotic cells is believed to be controlled by a group of closely related proteins referred to as cyclin-dependent kinases (CDKs).
These proteins are responsible for the timing of the cell cycle, determining when the cell should divide and when it should enter a quiescent state.
They are also responsible for making sure the cell progresses through the various stages of the cell cycle in the correct order. CDKs are activated by the binding of cyclins, which are proteins that are present in the cell at different times in the cycle.
The binding of cyclins to CDKs causes them to become active, which in turn triggers the cell to progress through the cycle. As the cell progresses through the cycle, the concentration of cyclins decrease, causing the CDKs to become inactive and the cell to enter a quiescent state.

What is the difference between mitosis and meiosis?Mitosis and meiosis are both types of cell division, but they have different purposes. Mitosis is the process by which somatic cells (any cells in the body other than gametes) divide and produce two identical daughter cells with the same number of chromosomes as the parent cell. This is the way that cells reproduce to form new cells for growth and repair. Meiosis, on the other hand, is the process by which gamete cells (sex cells) divide to produce reproductive cells with half the number of chromosomes as the original cell. This allows for genetic diversity in offspring.

D) The chimp and the mouse have the most similar characteristics.
Explanation:
which of these relationships is true of an uncharged atom?
The number of protons is equal to the number of electrons is the relationship that is true of an uncharged atom.
Atomic structure dictates that the number of protons in an uncharged atom is equal to the number of electrons.
This relationship is essential to understanding the behavior of atoms and molecules.
It's important to note that this applies only to uncharged atoms; atoms with a charge, either positive or negative, will have a different number of protons and electrons.
Atoms are the building blocks of all matter, and they consist of a nucleus surrounded by one or more electrons.
The number of protons in the nucleus of an atom is always equal to the number of electrons orbiting it.
This relationship is true for all uncharged atoms, meaning that the number of protons and electrons always match up, allowing atoms to stay in a stable, neutral state.
