Answer:
Your answer is most likely D) ss.
Purebred means not bred with anything else, which would mean that the only genes available would be ss.
Answer:
Most like a police officer. Because the cell membrane allows things in and out of the cell, as for a police officer in and out of a crime scene

Answer:
natural selection
Explanation:
Darwin proposed <u>natural selection</u> as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
<em>For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.</em>

Answer:
Use a step wise process
Explanation:
In order to find the presence of the recombinant protein:
- Culture the cells that you believe harbors the plasmid for the recombination protein (+) and also cells that do not (-). This is your control.
- Extract the plasmid from both strains.
- Observe the plasmid map and the area of your insert. Use this to select the restriction enzymes at the beginning and the end of the YFG gene. You can also use a restriction site inside the gene but not in the plasmid for better control.
- Perform the restriction enzyme digest on both (+) and (-) according to your protocol and separate using gel electrophoresis.
- Observe the separate bands that you see. In the (+) there should be a band that is the size of your insert and a larger band that is the size of your plasmid control band and in the (-) there should be a single band that is the size of the plasmid but non the size of the insert.
