Answer:
to get a Repeating answer so you know the first time wasn't a fluke
Explanation:
What are the drop down menus for each?
If the scientists are studying the effects of different temperatures on the processing speed of a computer chip then they would need to know the temperature inside the computer.
However, your questions doesn't include the full question text, so I cannot be sure what answer you need.
If the question is what do they need to know to do this, the answer is C.
If the question is how could they measure this when they subject the computer to different temperatures, then the answer is D.
There's sexual reproduction and asexual reproduction. Sexual reproduction involves both male and female in order to reproduce, while asexual reproduction involves an organism reproducing on its own without the help of another partner.
This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
