Metal -a solid material that is hard, shiny, malleable, fusible, and ductile, with electrical and thermal conductivity.\
nonmetal an element or substance that is not a metal.
Flu vaccines need to be revised and changed every year because the flu virus constantly mutates. Flu viruses can change in two ways: drift or shift. Antigenic drift occurs when genes of the virus slowly change during replication until the immune system no longer recognizes it. On the other hand, antigenic shift occurs when a major change in the virus happens. This usually leads to a totally different kind of virus. This is what happened during the H1N1 scare in 2009.
DNA viruses like mumps are less prone to mutation due to the presence of DNA polymerase. RNA viruses are more prone to mutation because they undergo reverse transcription to simulate the role of DNA.
anwser:
A
Explanation:
calibrated to test and see if the temperature correctly
Answer:
The yellow allele could start to become dominant, or the ones without that allele would die out.
1.A control group is important to an experiment because it allows you to eliminate and isolate those variables.
2. Controlling variables is important because slight variations to the experiment set up could affect the outcome significantly
Hope this helps :)
