Answer:
447 calories
Explanation:
1 gram of fat is 9 calories
1 gram of carbohydrate is 4 calories
1 gram of protein is 4 calories
In one granola bar:
5 grams of fat = 5 x 9 = 45 calories
19 gram of carbohydrates = 19 x 4 = 76 calories
7 grams of protein = 7 x 4 = 28 calories
for a total of 45 + 76 + 28 = 149 calories
If Carter ate 3 granola bars then 149 x 3 = 447 calories
They can conclude that the epicenter is the same distance from both recording stations.
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
