Answer:

D. Crossword Puzzle Performance

Explanation:

In experiments, we have the Independent and Dependent variables. The dependent variable is the variable being measured while the independent variable influences the dependent variable and can be manipulated by the exprimenter. In the scenario above, the Independent variable is the stress task vs. no stress task which is manipulated by the researcher as he has the power to assign the participants to either groups.

The effect of the stress task would influence the performance of the participants at the crossword puzzle which is a measure of cognition. Therefore, the later becomes the dependent variable in the research because the cognition ability reflected in the crossword puzzle performance is the variable being measured.

Since 2015 san francisco has sent its discarded msw to a landfill located in which bay area community?
SashulF [63]

The final detail that units San Francisco aside is the sheer scale of its recycling and composting operations. As for the compost, all of the metropolis's backyard waste and food scraps are added to Jepson Prairie Organics in Vacaville, approximately 60 miles northeast of San Francisco.

The pleasant time to visit San Francisco is from September to November. trust it or no longer, fall offers a number of the metropolis's warmest temperatures 12 months-round, now not to mention fewer crowds than summer. Spring is any other suitable time to go thanks to its slight temperatures and shortage of rain (compared to other parts of California).

To the east, heat within the valley creates thinner air and occasional stress. The valley becomes like a vacuum that desires to be stuffed with the aid of the heavier marine layer. It pulls that layer over San Francisco, which usually makes the town cooler than other parts of California -- and u. s. a . -- in the summertime.

San Francisco, officially the metropolis and County of San Francisco, is a commercial and cultural center within the northern area of the U.S. country of California. The city right is the 17th maximum populous in America, and the fourth maximum populous in California, with 815,201 residents as of 2021.
