the test
tube must be swirled at a steady rate to facilitate the liberation of CO2 gas from the
solution
The reaction vessel should be submerged in the water bath as far as possible to keep the
entire contents at the temperature of the water bath. There is a valve attached to the rubber stopper that should be open
while attaching the assembly to the test tube, and then closed just before the start of data collection
Answer:
Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.

Answer;
Forward chaining and backward chaining are Similar in that;
Both are used to teach a chain of behaviors.
Both use procedures,
Both teach one behavior at a time and chain the behaviors together.
Both procedures use prompting and fading to teach each component
Explanation;
-Backward chaining; When you teach the last stimulus-response component first. Then teach the next to last component and so on.
-Forward chaining; Teach the first stimulus-response component first. Then teach the second component and so on
