During a limited movement of the nerve, axonal transport also <u>slows down</u>.
Axonal transport/axoplasmic transport/axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm.
Slow axonal transport is the movement of cytoskeletal polymers and cytosolic protein complexes along axons at average rates on the order of millimeters per day, which corresponds to nanometers per second.
Axon transport mechanisms play a major role in transporting nutrients, organelles and other molecules towards the presynaptic terminals.

Answer:
c. Some codons specify the same amino acid.
Explanation:
Codons are triplets of nucleotides in mRNA that is used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Answer:
The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."
Explanation:
* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are evolving, meaning they are being used in a larger quantity now.
* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.
* As a result of the machines being developed as an Engineering progress which serves the work of people on the farms, there tends to be less manual labor that would be initially required to run a farm. The machines are now serving the work of human beings (laborers) now.
