Answer:
--> Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
--> Molecules that have ends with partial negative and positive charges are known as polar molecules. It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances. Water is a good solvent due to its polarity.
Answer:
The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.
An increase in ATP levels would tend to inhibit the PDH.
<h3>The oxidation of pyruvate</h3>
After the break down of glucose through the metabolic pathway known as glycolysis, the end product, pyruvate, is converted to acetylChoA in the citric acid cycle.
Pyruvate dehydrogenase (PDH) is the first enzyme of the citric acid cycle that is activated by its substrate pyruvate and inhibited by its products acetylChoA together with Adenosine Triphosphate (ATP).
This means that an increase in ATP negatively regulates the enzyme, pyruvate dehydrogenase.
Therefore, an increase in ATP levels would tend to inhibit the PDH.

1). it either lowers or increases the activation energy. 2). it modifies the rate of the reaction
Never learned it. Sorry! I wish I could help.
