Plants tend to grow toward light. This is why plants placed on a sunny windowsill grow toward the window rather than experiencing a more even growth pattern. Mrs. Fairchild wants her houseplants to grow more evenly. She wonders if turning the houseplants will encourage even growth, but she doesn't know how often she needs to turn the plant, so she sets up the following experiment. Mrs. Fairchild purchases four identical plants. Each plant is about the same height and is planted in the same type of pot with the same type and amount of soil. She places a stick into each pot near the stems of the plants. The vertical sticks form a right angle with the top of the soil. Next, she places all four plants on the same windowsill, so they all receive the same amount of light each day. Plant 1 stays in the same position throughout the experiment. Plant 2 is turned 180 degrees every 12 hours. Plant 3 is turned 180 degrees every 24 hours. Plant 4 is turned 180 degrees every 48 hours. Mrs. Fairchild monitors the plants daily. She counts the number of leaves on each side of the plant, and she uses a protractor to measure how far each plant is leaning away from the stick. What is the test variable (independent variable) in the experiment?

A. the number of leaves on each side of the plant

B. the type of plant that was used

C. the distance that the plants leaned from the vertical stick

D. the amount of time that passed between turnings

D. The amount of time that passed between turnings.

Explanation:

Variables A-C are resultants of the manipulation of the independent variable. D, time, is the only variable that would not depend on the change of another variable and cannot be manipulated. Variables A-C are resultants of the change in time, thus D would be the independent variable.

in brief the senate may propose or concur with amendments as on other bills.

explanation:

the topics being handled in article 1, section 7, of the u.s constitution, revolve around two issues: the first, the correct procedure to pass legislation regarding revenue production through tax, and the second, the correct process for creating and passing law. in the first case, the text of the constitution literally states that all bills regarding the raising of money, or revenue, need to first be proposed by the house of representatives, although the senate may also play a role here by either proposing such a bill to the house, or agreeing with one being proposed by the house. the second portion, speaks about the process to create, pass and enact legislation. the bill must first be raised by one of the houses, then it must be voted by the plenaries of both houses, and then, it must be presented to the president of the united states, who will either accept it, or veto it, and send it back for reconsideration. if it is not sent back, then the bill is passed into law. if sent back by the president, then the house where the bill originated from will vote again, and if passed by two thirds of the majority, then it goes to the other house, with the observations from the president, for voting. if it passes there as well, then, the bill becomes law, with a few exceptions. this is what is explained in article i, section 7, of the u.s constitution.

concurrent jurisdiction is the ability to exercise judicial review by different courts at the same time, within the same territory, and over the same subject matter. for instance, a domestic violence matter may be heard in either a general civil court or a family court in the same county. whichever court actually exercises its jurisdiction first will do so exclusively.
