Answer: Neither Sandra nor Marissa will be in her THR zone.
Explanation:
1) Actual pulse of both Sandra and Marissa : 144 bpm
2) Decrease of 20 bpm ⇒ 144 bpm - 20 bpm = 124 bpm
3) Sandra's TRH is in the range 135 - 172 bpm.
Since 124 < 135, she will be below the range.
4) Marissa's TRH range is 143 - 176 bpm.
Since, 124 < 143, she is below the range
In conlusion, neither Sandra nor Marissa will be in her THR zone.

Humans impact the environment, which can, in turn, have an effect on human health. Pollution is caused by human activity, and it also affects human health. Air pollution can cause respiratory problems and water pollution can lead to digestive problems. As human health is affected by these issues, concern increases and policies are enacted that address the causes of the issues. These policies do benefit the environment, but are, in part, brought about by concerns over human health.
An atom of sodium-23 (atomic number = 11) with a positive charge of +1 has total number of 10 electron and this atom has 11 protons and 12 neutron.
Protons, neutrons, and electrons make up an atom, with hydrogen being the sole exception since it lacks neutrons.
Given: An atom of sodium-23 (atomic number = 11) has a positive charge of +1.
So, total number of electrons it have = 11 -1 = 10.
total number of proton it have = 11.
total number of neutron it have = 23 -11 = 12.
