goblinko [34]

In human audition, the vibration of the ossicles is triggered by the vibration of the tympanic membrane (the eardrum) and transmitted directly to the fluid and membranes of the inner ear.

The inner ear is shaped like a snail with a thousands of tiny hair cells in it and it is called the cochlea. Hair cells change the vibrations into electrical signals that are sent to the brain through the auditory nerve.

Answer:

Capsule

Explanation:

In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.

The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.

In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.

Thus, the capsule is correct.

the following shows a graph of the energy changes taking place as a chemical reaction progress. If an enzyme is added, which arr
Alekssandra [29.7K]
The arrow representing the activation energy will decrease in magnitude.

This arrow will be beginning at the x-axis and going up to the maximum of the graph. The reason that its magnitude decreases is because enzymes provide  alternate pathways to reactions; the new pathway has a lower activation energy, so the reaction occurs faster when an enzyme is added. This is why enzymes are referred to as biological catalysts and are a vital part of an organism's body

Explain why a lock and key are used to describe the way in which an enzyme works. Describe any ways in which the
LiRa [457]
The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.
2
This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.
