The following statement that is NOT part of the Cell Theory is B
Answer/Explanation:
DNA is replicated through semi-conservative replication. This produces two copies of a double stranded DNA molecule, each possessing one copy of the original molecule. This occurs prior to the cell dividing, in the synthesis stage of the cell cycle.
Enzymes use the original DNA molecule as a template to produce a new strand of DNA. This occurs through the progressive addition of nucleotides, which are added as complementary base pairs matching the template strand. This means the new strand is <em>complementary </em>to the template strand. This processes is generally free of errors, but errors can be introduced during replication, causing mutations in the DNA.
Answer & Explanation:
Vision is simply the sense or ability of sight; the ability to see or the perception of light. Tapetum lucidum present in most fishes especially the nocturnal ones and sharks, is located behind the retina. It is a special eye structure whose function of which is to return rays of light that have escaped from the retina back to the retina to improve vision. This has enabled them to survive in an environment where light readily disappears due to depth.
Imagine a very tiny person is walking through the auditory tract, from the ear canal through to the auditory nerve. when that tiny person reaches the cochlea and walks along the basilar membrane, Loud frequency sounds will disturb their walk most at the base of the cochlea, and soft frequency sounds will disturb their walk most at the tip of the cochlea, the cochlea communicates with the middle ear by two holes closed by membranes: the oval window, which limits the base of the vestibular ramp and on which the abutment is attached and the round window that closes the base of the tympanic ramp and which serves as a decompression system.
