Think about the different characteristics that stems have, and write them down. Then go outside and examine at least ten different types of plant stems. Look for stems with the characteristics you listed, and add any new ones you discover. When you return from your observations, answer the following questions for each plant on your list:

What benefits does each stem type have for the plant?
Do the characteristics of a particular stem type provide a benefit not found in other stem types?
Does the stem type help to protect the plant? If so, how?
Classify each stem as herbaceous or woody.

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
