<h3><u>Answer;</u></h3>

A) Many scientific investigations have provided evidence to support this as the best explanation of the data.

<h3><u>Explanation</u>;</h3>
  • <em><u>Molecular clock is a method that is used to determine time, based on base-pair substitutions. Molecular clocks use the rates of molecular change to deduce the divergence time between two lineages in a phylogeny.</u></em>
  • They work best when they can be "calibrated" with other markers of time, such as fossils with known ages.
  • Molecular clocks use neutral theory to date events within a phylogeny and can be affected by the segments of DNA being examined and relative sizes of the populations.

what is the pressure, in atmospheres, of 2.97 mol h2 gas if it has a volume of 73 liters when the temperature is 298 k? 0.50 atm
Triss [41]
P x V = n x R x T

P x 73 = 2.97 x 0.082 x 298

P x 73 = 72.57492

P = 72.57492 / 73

P = 1.0 atm

hope this helps!
