A student models convection currents in a laboratory activity. How are the convection currents in the student’s model different

from the convection currents in Earth’s atmosphere and oceans? The warm air in Earth’s atmosphere and the warm water in Earth’s oceans sink instead of rise. The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below. Convection cells in Earth’s atmosphere and oceans flow in the same direction instead of opposite directions. Cold air in Earth’s atmosphere and cold water in Earth’s oceans are less dense than warm air and warm water instead of being more dense.

A disinfectant spray bottle says it eliminates 90% of bacteria with each application. You apply the disinfectant once to a count

kotykmax [209]

Applying the disinfectant once removes 90% of the bacteria, leaving 10% remaining.

Applying it a second time eliminates 90% of that remaining 10%, so you calculate 10 minus 90% of 10 to find the leftover bacteria after two applications.

$.90 * .10 = .09$

$.10 - .09 = .01$

This results in only 1% of the bacteria still being present, meaning that 99% of the original bacteria have been eradicated.

Determine which of the following graphs reflects this scenario: acts of kindness increase among students receiving character edu

vovikov84 [265]

Hello. The graphics related to this question were not included, making it impossible to address your inquiry. However, I've created a model chart that illustrates the situation described in the question and is attached below. In the chart, it becomes apparent that as more students attend character education classes, their acts of foolishness increase. Conversely, these actions appear to decline as students participate less in these classes, achieving a very low level for those who have not attended any.
