Answer:
When the required direction of transport is opposed to concentration levels, a cell <u>will </u> expend energy to force<u> ions</u> across its membrane.
Explanation:
If the concentration gradient is opposite to the direction of transport of minerals, then the cell will use energy to transport mineral ions from a lower concentration to a higher concentration. The most common process through which this happens is termed as the active transport.
The process of active transport is opposite to passive transport. In passive transport, molecules move from a higher concentration to a lower concentration.
Answer: During photosynthesis, CO2 is absorbed and oxygen is released, whereas during cellular respiration, oxygen is absorbed and CO2 is released.
<h3><u>Answer;</u></h3>
absorbed by Earth’s core
When energy from the sun reaches Earth, it is not <em><u>absorbed by Earth's core.</u></em>
<h3><u>Explanation;</u></h3>
- <em><u>The energy from the sun reaches the earth, such that 23 percent of the incoming solar radiation is absorbed by the atmosphere by water vapor, dust and ozone. </u></em>
- <em><u>48 percent of the solar energy is absorbed by the earth's surface, this translates to 71 percent of the energy which is absorbed by the systems of the Earth.</u></em>
- <em><u>The remaining 29 percent is reflected back to space by clouds, atmospheric particles etc. </u></em>
