The mass of one atom of carbon in the correct number of significant figures is 1.99×10-²³. There are four significant figures each in both the atomic mass of carbon (12.01 g) and Avogadro's number, so the answer must also have 4 significant figures. The operation is shown below:

Food handlers who does different cutting surfaces base on cutting raw vegetables and raw poultry, is trying to prevent contamination as doing this prevents food from being mixed and from being contaminated. It is also a way of having the food to be prepared properly and in a more sanitized way for people to eat.

Answer: The taproot
Explanation: A deep taproot helps plants use moisture held in deeper soil layers, and they can have great drought resistance compared to fibrous-rooted plants. An example is honey mesquite (Prosopis juliflora), which is known to send its roots down 150 feet to get water.
During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'
Answer: Option B
<u>Explanation:</u>
The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.
Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
