Jason wanted to find out how he could increase the number of popcorn kernels that pop when cooked. he hypothesized that more kernels would pop if he used more oil. to test this, he placed 100 kernels of “pop rite’ popcorn into a popcorn popper that contained different amounts of oil. he used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. he used 5 ml of oil as the control. he conducted the test 3 times for each amount of oil. he then counted the number of kernels that had popped. each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?
