Answer:
31. Seatbelts lock in place to make sure you don't go flying into the windshield.
32. Friction causes the soccer ball to slow down. If we were to kick a soccer ball in space, where there is no friction, it would keep on rolling until it eventually hits something or goes out of sight.
33. Heavier loads will make the vehicle move off of the table. The heavier the weight, the quicker the vehicle will roll. Loads that are something very similar or lighter than the vehicle won't make the vehicle move by any means.
34. Gravity is the power pulling the piano toward the Earth.
Friction would happen with an unpleasant surface, making it a lot harder to push the piano up the ramp.
35. Wagon C
Wagon C has the least boxes and minimal measure of mass, making it simplest to move.
36. I would move the crates so every cart has a similar measure of boxes, making them equivalent in mass. This would make them all take a similar measure of power to move them.
Explanation: I have the answer key
When referring to knowing where to find something when you need it you mean that you do not need a memorization of all things, you just need a source to find it when in need. I hope this answer suited your needs.
The land and the aquatic are the two types of global food webs
Answer: c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
Explanation:
Positive PCR control can be defined as the control sample that is used as a benchmark for comparison with the results of the PCR or polymerase chain reaction. It comprises of artificial genome or primers. For amplification of microbial DNA synthetic oligonucleotides are used as targets of each primer and a hydrolysis probe is also used. As it is already known that primer as well as hydrolysis probe has the specificity for the DNA strand so it will help in identification of the specific region or sequence in the DNA structure. Wolbachia DNA can be detected if the positive control consists of samples of students affected by Wolbachia that can give indication of whether the Wolbachia species is the same as that of the one which has caused infection.
