Identify the hypothesis. Maria collected a tape measure, cardstock, and printer paper. She went to the hallway outside her science classroom to conduct her experiment. First she folded an airplane out of cardstock. She noticed the airplane was very sturdy because it was made of cardstock, which is heavier than printer paper. She then used the printer paper to fold a second airplane. The two airplanes were the same size and design. Standing in the same place for each throw , Maria threw the cardstock airplane ten times and used the tape measure to find the distance the airplane flew after every throw. She repeated the throws and measurements with the airplane made of printer paper. Maria recorded her data in her lab book and graphed the results so she could compare the distances of the airplane flights.

Explanation:

Robert measured fifty grams of soil on a balance and placed the soil in a small cup. He repeatedthis process until he had ten cups of soil. Then he planted one bean seed in each of the cups.Robert was careful to push all of the seeds two centimeters deep and cover them smoothly withthe soil.All of the cups were placed in the same windowsill and received the same amount ofsunlight. He gave five of the bean seeds five milliliters of water a day. He gave the other five beanseeds two milliliters of water a day. Every other day Robert measured the bean plants to see howtall they grew.After he measured twenty times he compiled his data and made a line graph toshow the seed growth over time.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
