Answer:
each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.
Explanation:
DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.
Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
I believe the correct answer is B. Vibrate with the frequency of the received sound.
<h2>Explanation:</h2>
The ear is divided into 3 sections: The outer ear, the middle ear and the inner ear. The outer ear is funnel shaped leading into the head to collect sound waves and concentrate it to the middle ear. The middle ear contains the eardrum (tympanic membrane) which vibrates in response to the sound waves.
<h2>Further Explanation:</h2>
The middle ear contains the eardrum(tympanic membrane) which is a special type of membrane that is thin and taught to vibrate to the slightest sound waves. When the sound waves cause the vibration of the tympanic membrane depending on different frequencies, it will cause the 3 bones attached to it ( malleus, incus and stapes) to vibrate at the frequency the membrane vibrated. This motion will cause the round window of the inner ear to vibrate at the same frequency. The round window is connected to a structure called the organ of corti that contains many very sensitive hair cells. The inner ear is filled with fluid including the organ of corti. The vibration of the inner ear is transmitted into this fluid and the back nd forth motion of the fluid will cause vibrations on the hair cells in the base of the organ of corti. These cells are specially adapted and transmit the vibrations as electrical signals to the sensory neurons attached to them. These neurons then will carry the converted sound energy to the brain via major cranial nerves where the brain will interpret these signals as sound waves. Interpretation is continuous and very fast and that is why a person can hear things simultaneously. These hair cells are the ones that get destroyed when listening to loud music making a person go deaf. Bomb blasts and gunfire sound also tear the tympanic membrane and the destroy the sensory cells and this is why many war veterans have hearing problems.
