It's important so that they know exactly where the disease started. Knowing who patient zero is helps them to identify who that person interacted with. From there, they can determine where the disease spread to. This will aid them in stopping the disease before it spreads any further.
Rapid consumption of alcohol in a very short period of time is very dangerous; due to delayed absorption the drinker will not know how really drunk he is and intoxication from that kind of drinking can last for days and even weeks.
Besides, such drinking pattern may make the whole body system to collapse causing death. Such drinking may also lead to alcohol induced psychiatric disorder.
Think it’s answer D but it maybe B
hope this helps!!
sorry if it’s wrong
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the chart referred to in the question. However, what appears to be the case is that the three nitrogenous bases represent codons (and the missing chart is the codon chart). The mutation that has the potential to cause more damage will be the one that would change the amino acid formed from the codon change.
A. CAU to CAC: The codons CAU and CAC both form the amino acid histidine and thus is not expected to cause a major damage.
B. UGU to UGC: The codons UGU and UGC both form the amino acid cysteine and thus is not expected to cause a major damage.
C. UCU to UUU: <u>Codon UCU forms the amino acid serine while the codon UUU forms the amino acid phenylalanine</u>. Thus, this eventual change in the amino acid formed has the potential to cause a major damage and thus option C is the correct option.
NOTE that a codon is a sequence of three DNA/RNA nucleotides that corresponds to a single amino acid.
Answer:
a glass of muddy water
Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.
Hope that helps.
