Answer:
The scientist can insert the DNA into bacteria
Explanation:
Bacteria are frequently used in biotechnology to make proteins scientists are interested in. If they know the gene and the sequence of the gene that makes the protein product, they can insert that gene into a vector that will cause the bacterial transcription and translation machinery to produce the protein.
Firsts scientists clone their DNA of interest into a vector, a circular piece of DNA that the bacteria will transcribe. The vector is then introduced to competent bacterial cells. (Competent means there are holes in the bacterial membrane that allow them to uptake the gene and vector).
Once the vector is in the bacteria, it (and the gene of interest) will be transcribed and translated as it would in the chicken liver.
Sodium would lose an electron to become a positively charged ion.
Answer:
Tolerance to heat, light and parasite.
Explanation:
Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.
Answer: Fish are farmed by breeding them in controlled environments. Kennels sort of. They are huge cages in man-made resivours with temperature and water control. Once they have grown to be a certain size they are extracted and killed for their meat while the eggs are used to produce another batch of fish. Hope this was helpful :).
Answer;
-Evolution by natural selection
-The theory of evolution by natural selection states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.
Explanation;
-The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.
-Natural selection is the phenomenon that some traits confer a reproductive advantage (fitness), resulting in (a statistical expectation of) that trait increasing in the population over time (evolution).
