Answer: 10. Control Group
11. Identify the:
Control Group = Subject A
Independent Variable = The new and original itching powder.
Dependent Variable = The type of itchiness.
Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.
The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.
The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.
Explain how wind erosion might effect exposed rock
Answer:
Yo
Particles moved by wind do the work of abrasion. As a grain strikes another grain or surface it erodes that surface. ... As wind blows from different direction, polished flat surfaces create a ventifact. Exposed rocks in desert areas often develop a dark brown to black coating called desert varnish.

Elements in the same period have the same ________________________.
Answer:
Elements in the same period all have the same number of valence electrons.
Explanation:
"Elements present in horizontal rows are called as periods so elements belonging to the same period have same number of shell as the electrons are added in the same shell of the element."
Answer:
All of the elements in a period have the same number of atomic orbitals.
Explanation:
For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. As you move down the table, every row adds an orbital.
