Text- Many egg producers keep chickens in small cages that do not allow the chickens to move. Some people believe that this is unhealthy, so they buy eggs from chickens that are not caged 24-hours a day. These are sometimes called "free-range" chickens. The United States Department of Agriculture (USDA) allows chickens to be called free-range as long as the chickens spend some of their time outside. The European Union (EU), however, has several additional restrictions. One of these is that the farmers must provide enough outside area so that if all the chickens were outside, the density of chickens would be no more than 0.25 chickens/sq meter. (Wikipedia, 2014).question 1- How many square meters does the EU require for one chicken?

question2-A farmer in the United States wants to meet the EU guidelines. She measures her area in square yards (1 sq meter =1.196 sq yards). How many square yards does she need for 1,100 chickens?

The process through which populations of living things adapt and change is known as natural selection.

What is not natural selection examples?

Natural selection is the term used to describe this process of disparate survival and reproduction. Non-genetic changes that take place throughout an organism's lifetime but cannot be passed on to the next generation, such as gains in muscle mass brought on by nutrition and exercise, are not examples of evolution.
Natural selection is not influenced by chromosome number. The other three options stand for elements that influence natural selection. Natural selection can take place because of random DNA mutations that produce genetic variation in a population of species.
Natural selection is a straightforward method that results in long-term population changes in living things. In fact, it is so straightforward that it can be divided into five fundamental steps, which we'll refer to as VISTA in this instance: Variation, Inheritance, Selection, Time, and Adaptation.

Please Help: Determine which ordered pair is a solution of y = x^2 - 2. A) -2,6
B) 5, 21
C) -1, -1
D) -5, 24

Answers

The answer is C
The term "ordered pairs" refers to graphing and so it will always be in the order of x,y....x first and then y, ALWAYS, so this tells you that in every potential answer given, that the first number IS x and then
to solve for y (the second number) you must do as the equation states and square x,(the first number in the ordered pair you are testing), (squaring means to times it by itself) and then subtract 2, the answer to that, will give you the solution for y.....so......so try this out for all of the above listed potentially correct answers, only ONE will work out properly
Important: to do the equation, you must remember that a negative times a negative ALWAYS equals a positive....so
-1 * -1 = 1.....then the last step, subtracting 2 (-2)
1 -2 = -1......thus C : -1, -1.... is the only possible answer
