Answer:
In order to make E. coli bacterial cells glow green, we need to insert a gene that can be translated into the <u>green fluorescent protein.</u> This gene is well-known as <u>gfp</u> and can be inserted either in the DNA or plasmid of the bacteria. The genome insertion procedure would follow the conventional method where the DNA will be first cut using restriction enzymes and then would be ligated. This approach has been extensively applied to test the fate of bacteria in the environmental systems.
A schematic diagram on insertion of gfp in the plasmid of bacteria is shown in the figure. The left side diagram shows that gfp is inserted and right side figure shows glowing bacteria in the presence of UV.
Cigarette smoking and environmental chemicals
Tobacco smoke and certain environmental chemicals are known carcinogens (substances that can cause cancer in living tissue). The tobacco smoke from cigarette smoking contains harmful chemicals such as hydrogen cyanide, arsenic, ammonia, benzene, and many more. In fact, from 2009 to 2013, three out of 10 cancer deaths in the U.S have been attributed to cigarette smoking or exposure to tobacco smoke.
Glucose Produces food for plants in a food web
Humans have loads of cells so they can reproduce so it doesn’t matter if a cell dies e.g. when you cut your skin it fixes itself. Organisms with 1 cell will easily die and probably not live very long unless they can breed.
Answer Options:
A: The runner's body will convert stored fat molecules into energy.
B: The runner's body will create the needed energy by breaking down proteins.
C: The runner's body will supply the needed energy by producing starch.
D: The runner's body will produce the energy by activating the Golgi apparatus.
Answer:
A: The runner's body will convert stored fat molecules into energy.
Explanation:
When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.
If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.
