Answer:
-use PCR to amplify the gene for GFP
-perform a restriction digestion of the GFP gene and the plasmid
-ligate together the GFP gene and the plasmid to generate a recombinant plasmid
-transform bacteria with the recombinant plasmid using electroporation
-plate the bacterial cells, and screen for positive transformants
Answer:
Change in the vascular system.
Explanation:
High blood pressure occurs when the arteries in the human body system become rigid thereby making the blood pressure rise.
The cause for this situation particularly in older people is the changes in the vascular system or circulatory system.
This is said to be vasoconstriction which lowers the flow of blood in the circulatory system, thereby causing high blood pressure
Hence, since Mr. Ackah is a retired teacher, it is believed that he is an old man susceptible to changes in the vascular system or vasoconstriction.
Answer:
C) it is a polarized molecule, where the oxygen is slightly positive and the hydrogens are slightly negative.
Explanation:
The water molecule is polarized, but the oxygen atom is slightly negative and the hydrogens are slightly positive.
Electronegativity is a property that measures how much an atom will tend to attract electrons towards itself. Because electrons are negatively charged, the more electronegative an atom is, the more negative its partial charge will be.
Oxygen is much more electronegative than hydrogen, and thus it will attract the electrons in the molecule, keeping them away from the hydrogens.
