The answer is in scientific notation 34^67 42’063 1220.
The correct form for scientific notation is a x 10^b. where a is a number or decimal such that the absolute value of a is greater than or equal to 1 and less than 10, or 1 ≤ |a|. < 10. b is the power of 10 required to make the scientific notation mathematically equivalent to the original number.
To write this number in scientific notation, you must first shift the number of decimal places from the original number by 4 places between 4 and 2. We're subtracting from the exponent because we're shifting the decimal four places to the right.

Answer:
Independent variable: DIFFERENT TEMPERATURE
Explanation:
The independent variable of an experiment is the variable that the experimenter changes or manipulates in order to effect an outcome or response in the measured variable/dependent variable.
In this experiment, a scientist wants to determine how temperature affects photosynthesis. He sets up the experiment by adding 20ml of water at different temperatures to three test tubes. Hence, the independent or experimental variable is the DIFFERENT TEMPERATURES GIVEN TO EACH PLANTS IN THE TEST TUBE because it is what the experimenter changes in order to effect a measurable outcome i.e. oxygen released in each balloon as a result of photosynthesis, which is the dependent variable
Answer:
individual isotopes
Re 185 = 139.094
Re 187 = 232.815
Explanation:Correcting the typo error for natural abundance as 37 40 as 37.40 and 62 60 as 62.60
Answer is found as follows
For Re 185 natural abundance 37.40%
371.9087 x 37.40/100 = 139.0938538
six significant figures after rounding off = 139.094
For Re 187 natural abundance 62.60
371.9087 x 62.60/100 = 232.8148462
six significant figures after rounding off = 232.815
