Explanation:
Suppose that you and a friend see brightly colored pigeons like these at a nature park. Because pigeons are usually gray and white, you both wonder where these colors came from. Suddenly, your friend says, "I have a theory. These birds must get their colors from eating food that has the same colors."Is your friend's explanation a scientific theory? Give reasons to explain your answer
The answer is no. My friend's explanation is not a scientific theory.
A scientific theory is a tested and proven phenomenon. In order for a statement to become a theory, it must have been tested through experimentation by several independent researchers and found to be true. A mere statement based on perception with little or no experimental test is just a hypothesis and not a theory.
Instead of my friend to have said, "I have a theory", he should have said, "I have a hypothesis".

Determine the median value for foot width for males and for females.
Answers
The data set is missing in the provided question,however the correct data set is provided with answer :
Answer:
Median value :
For males: 9.25
For females: 7.65
Explanation:
Median value is the value that separates higher half to lower half values and is the center point of values of the given set. The method of the finding the median is to arrange the set in order of least to highest value and then if the set of values are even than it is the mid point of the set and in the even set the mean of the middlemost values would be median of the set.
Arranging set in ascending order
For males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13.
For females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17
For males mean of the middlemost number is : 9.3+9.2/2 = 9.25
For females mean of the middlemost number is : 7.5+7.8/2 = 7.65

A researcher is studying the number and arrangement of fimbriae covering the surface of a bacterial cell. Which type of microscopy would be most useful for this purpose?
Answers
Answer:
The electron microscope
Explanation:
Fimbriae are very tiny appendages of about 3 to 10 nm in diameter found on the surface of most Gram-negative and some Gram-positive bacterial cells. They are mostly utilized as a structure to adhere to one another, to other organisms, or any other surfaces.
Fimbriae generally contain adhesins, a virulence factor that facilitates adhesion to surfaces and due to their tiny size, they can only be viewed using the electron microscope - the scanning electron microscope to be precise.

Flat surface and force applying body.
Explanation:
Flat surface and force applying body are the tools used by the physicist in order to know the amount of force required to push the body. Mass of the body and the acceleration produced from the application of force are the measurements recorded by the physicist. By multiplying value of mass and acceleration we can measure the amount force required to push the heavy box.
