Answer:
Molecules stop moving at freezing point. Helium has the lowest boiling point. The molecules move very quickly at boiling point.
Explanation:
Heating up- molecules move faster. Cooling down- molecules move slower
As for this problem, the most probable answer and the most likely answer for this one would be D. the effect of pesticides on organisms in the environment.
A toxicologist would only study about chemicals and their effect on organisms in the environment. Pesticides are chemicals made to combat organisms that aren't wanted particular parts of the environment such as crops and rice field. These pesticides don't just affect those organisms that are targeted, but even the users and other organisms that may have come in contact with pesticides.
<span>You are likely talking about aerobic respiration rather then just glycolysis based on the options: The third option seems best, pyruvate is heavily oxidized during the Kreb's cycle and removed as CO2.
Wrong options
Option1- FADH2 is also another highly energetic molecule produced during
Option2- oxidation of pyruvate is a highly directional process and can be considered irreversible in the cell
Option4- Aerobic respiration RELEASES energy from pyruvate and the into NADH/FADH which is then captured by the electron transport chain. An exergonic rxn would take in energy and would not happen spontaneously
This can be looked from different perspectives, but let me know if my answer made sense. </span>
I just had this answer but it hasn't been graded. I put 1. Meteor impacts, 2. volcanic gases and 5. Milankovitch cycles. I didn't put earthquakes because I wouldn't think it would affect the climate changing since they just affect ground movement.
