Answer:
Polarization and depolarization
Explanation:
The transfer of signal happens by the exchange of sodium and potassium ions in and out of the cell membrane of neuron.
Answer:
The bipedality
Explanation:
<u>One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size</u> because Lucy actually had a small skull which could indirectly be translated to small brain size.
NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.
Answer:
1. Restriction enzymes
2. DNA ligase
3. ?
4. ?
5. ?
-------------------------------------------------
1. Identify your gene of interest (the one that produces human insulin in this case).
2. Isolate it from the rest of the DNA via restriction enzymes. Also extract a plasmid from a bacterium.
3. Use the restriction enzymes on the bacterium as well.
4. Join the cut plasmid and your gene of interest via mixing them and with the help of DNA ligase.
5. Insert the recombinant plasmid into a host cell. The plasmids are taken up by the bacterium by transformation.
6. Select for cells that have been transformed by linking the gene of interest to an antibiotic resistance gene or a report gene.
-------------------------------------------------
1. Agricultural Uses, we can insert disease-resistant genes into plants for example
2. We can amplify the DNA found at a crime scene to more easily trace down suspects
3. Medical Uses; we can more easily detect diseases and test for viruses (via amplification of blood samples).
The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound.
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.
