The answer is eardrum (or tympanic membrane).

As sound waves enter the ear, they travel through the outer ear to the eardrum. By striking the eardrum, it begins to vibrate. Sound vibration is transmitted to the hammer (malleus), then to the incus and stapes. Stapes vibration moves the oval window and it is passed onto cochlea. The cochlea contains the receptor organ of hearing which translates the sound vibration into impulses which are then sent to the brain.

serious [3.7K]

Answer:

Penicillin binds and inhibits bacterial enzyme DD-transpeptidase.

Explanation:

Penicillin is made up of 4 rings of β-lactam and acts by binding to DD-transpeptidase of bacteria. The DD-transpeptidase facilitates the cross-linking of the peptidoglycan cell wall of bacteria. This leads to malformation of the protective cell wall of the bacteria and causes it to lyze and die.

Which factor does not greatly influence the rate of
jonny [76]

Answer:

a. transcription

Explanation:

<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>

The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.

<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>

The only option that has no known effect on sugar transport in the phloem is transcription.

The correct option is a.
