Proteins are broken down into amino acids whereas fats are digested mostly into fatty acids & glycerol
He wondered, Does the position of the pot determine the growth of the stem?<span>
He hypothesized that the plant’s stem grows perpendicular to the soil.
</span><span>To test his hypothesis, Brian placed the pot horizontally. He checked the plant after two weeks.
</span>
<span>Brian observed that a plant’s stem grows against gravity.
</span><span>On analysis, Brian found that the plant grew parallel to the soil. He modified the hypothesis, and then retested the experiment.
</span><span>Brian communicated the results to his science class.</span>
Answer: A
I hope this helped you :)
And can I please get brainliest?
Electricity is added to recharge a battery. A third phosphate group is added to ADP to form ATP.
ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.
ADP is converted to ATP by the following reaction:
ADP+Pi+energy⇄ATP
The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.
