The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
The correct answer is <span>B. roots that grow in the direction of a water source
This is not about structural support but rather about searching for nutrients. It's a behavioral, functional adaptation, not a structural one. </span>
I dont really understand where someone would get this information. was there a document or article you were supposed to read before this if so that would be very helpful.
Answer:
Surface Tension
Explanation:
It is the combination of the legs not being wetted and the surface tension. The legs of water striders are hydrophobic. Water molecules are strongly attracted to one another. This is due to "hydrogen bonding": a proton in water is shared between two oxygen atoms of two water molecules.
Answer:
Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.
