Answer:
35 parts per thousand
Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand.
Explanation:
There are four different bases that make the DNA molecule:
Adenine, Cytosine, Guanine, and Thymine.
Due to chemical properties of the bases, there are two pairs of bases that are complementary, Adenine and Thymine and Guanine and Cytosine.
So, if we have 16% of Adenine, there must be the same amount of Thymine, since they only appear in a pair.
16% of Adenine + 16% of Thymine - 32 %
the rest of the abundance of the bases can be calculated by subtracting the 32% out of the 100%: 100-32 = 68
So, Guanine and Cytosine make up 68% of the bases, and a half of that number is the amount each of the bases has in the total amount. 68/2= 34
16% Adenine - 16% Thymine
34% Guanine - 34% Cytosine
Answer:
controlled experiments
Explanation:
Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.
