The question is already answered.
Answer:the xylem transports water and nutrients throughout the plant
the pholem transports food throughout the plant.
Explanation:mark brainliest cuz like i gave u the answer lol
High temperature and pressure produce the highest rate of reaction. However, this must be balanced with the high cost of the energy needed to maintain these conditions. Catalysts increase the rate of reaction without affecting the yield. This can help create processes which work well even at lower temperatures.
I hope this helps you.
Answer:
Oxygen
Explanation:
because oxygen is used when making and sustaining a fire.
I think this seems like something is missing from the question
Answer:
b) the oxygen atom of one molecule and a hydrogen atom of an adjacent molecule
Explanation:
In a H₂O molecule there are two O-H bonds. The O atom being more electronegative pulls away the shared pair of electron in the covalent bond more towards itself thus O gaining a partial negative charge and H atom getting a partial positive charge. Thus a dipole exists in the O-H bond in the H₂O molecules. Thus in both liquid water and solid ice there is a weak attraction or hydrogen bond between the oxygen atom of one H₂O molecule and a hydrogen atom of an adjacent H₂O molecule.
