Grasses and plants are producers, guanacos are herbivores and are primary consumers and pumas are predators and secondary consumers
Answer:
Explanation:
Elements on the right side of the periodic table are very likely to form negative ions -- all of those except elements in the 8th or 18th column (depending on how your periodic table is numbered).
K and Mg are on the left side, so they will not form negative ions.
They give up 1 (for K) electron and 2 (for Mg) electrons which will leave plus charges for the ions.
On the other hand S and I are on the right side of the periodic table. They will take on electrons and hence be charged with a minus.
Answer : Option B) Plant stomata opening and closing to maintain homeostasis.
Explanation : Claude Bernand was a French Physiologist who first discovered about "homeostasis" which is defined as the controlled stability of the internal milieu, or internal environment, of cells and tissues in plants.
In plants stomatal opening and closing was done for maintaining homeostasis with the external and internal plant environment.
<h2>Answer:</h2>
<em><u>The kinetic energy of the air molecules in the cave is less than the kinetic energy of molecules outside the cave.</u></em>
<h3>Explanation:</h3>
The kinetic energy of any molecule is directly proportional to the temperature of the gas.
Temperature of a gas is the heat energy provided to the molecules. As the temperature energy increase the molecules of the gas will move fastly and collide with each other.
So we can know the kinetic energy of molecules in the gas by measuring its temperature.
Hence the temperature of the cave is less than outside, so the kinetic energy will also be low.
