Amy set up the following experiment to study how plant growth is influenced by weather conditions. mc052-1 One pot will model normal growing conditions, and the other will model drought conditions. Which of the following factors is it most important for Amy to change to model drought conditions?

The original purpose of this experiment was to see in which soil temperature (32°c, 18°c or 5°c) more seeds will sprout. The results of the experiment showed that A and B sprouted faster then the other four by one day. Note that your results may be different.

Explanation:

Plant growth is affected by several factors such as seed variety, amount of water, soil type, amount of light, temperature, humidity, and other. The factors are displayed in the diagram below. You will use two variables in the experiment: seed variety and amount of water. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN). Students will conduct an experiment to evaluate whether plants need air in order to survive and grow. If any environmental factor is less than ideal, it limits a plant's growth and/or distribution. In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack. Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
