The hydrogen bonding creates a dipole between the H and O atoms where the O "hogs" most of the protons
I'd recommend making a picture with arrows showing the process. Like this: for identifying the problem, you can do someone pondering. For explore, someone surfing the web. For design, someone drawing something. For create, draw someone physically putting together things and making a product. For try it out, show somebody testing it (example:if the object was a paper airplane the person would throw it). For make it better, draw someone improving the object. Remember to link them all with arrows showing the steps. Hope this helped.
Answer:
Natural enzymes called restriction enzymes Can cut and copy DNA at specific sites. Then the DNA fragments can be separated by the process of gel electrophoresis.
Explanation:
Restriction enzymes recognize restriction sites in the DNA and bind to them. Then they will cut the two DNA strands and give two separate sequences of DNA that can bind to another piece of DNA if the sequence match.
Gel electrophoresis will separate the different cut fragments of DNA by size and charge. The scientists put the DNA fragments in indentations in the gel, then the gel is placed into a gel box with a buffer solution, a negative electrode near the indentations, and a positive electrode on the bottom. When the electric current goes through the gel, the DNA fragments will start to descend towards the positive electrode since the DNA has a negative charge. As a result, DNA strands will descend faster through the gel's pores than the larger strands. The final step is to dye the gel to see the different bands with fragments of various DNA sizes.
Answer:
Nitrogen fixing bacteria is the organism which is responsible for the fixing of atmospheric nitrogen for the plant.
Explanation:
Nitrogen fixing bacteria is a type of bacteria which fixes atmospheric nitrogen into ammonium and nitrates form. Plants are unable to take atmospheric nitrogen so it must be converted into available form i. e. nitrates and ammonium. Examples of nitrogen fixing bacteria are Cyanobacteria and Azotobactor etc.
