<span>A molecule is a molecule that transfers energy from the breakdown of food molecules to cell processes</span>
Answer:
Tundra
Explanation:
Permafrost is a layer just beneath the surface of the ground that never thaws.
Answer:
Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.
<u>Phyletic</u><u> </u><u>gradualism</u> - slow, but constant gradual change; supported by transitional species in the fossil record
<u>Punctuated</u><u> </u><u>equilibrium</u>- long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found.
<h2>Respiration is a <u>
redox</u> reaction where sugar is oxidized to produce energy.</h2>
Explanation:
Respiration is a biochemical process that involves a series of reactions most of which are redox reactions to produce energy by oxidizing sugars.
It involves the breakdown of glucose (glycolysis) in the cellular mitochondria to produce ATP which is the fundamental unit of energy in the human body
<span>The
availability of nutrients; solar energy is available year-round, but
nutrients are trapped in deeper waters because the permanent thermocline
prevents mixing between surface water and deeper water</span>
