Active transport.
Passive transport, being its opposite, requires no energy at all. Therefore, active transport would require energy or ATP in order to move across.
Hope this helps!
Answer:
The answer is "False."
Explanation:
The sentence above is stating that you can<u> "measure"</u> and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."
Although you can describe the atmospheric condition or the climate just by walking out the door,<em> you can never measure it.</em>
Thus, this explains the answer.
The statement is false, A cell is to tissue as an organ is to its organ system, not the other way around. as multiple cells make up tissue, organ systems do not make up an organ.
Answer:
endothermic reaction
Explanation:
This means it cannot occur without energy (from the Sun).
Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
