What sort evidence must be gathered to support the idea that all living things are composed of cells
a. comparison should be made between nonliving things in living things to determine any similarities in their structure
b. samples of many kinds of living things should be examined under a microscope to identify the presence of cells
c. the functions of cells are many different living things should be monitored to see if they are identical
d. nonliving things should be examined to verify that the smaller part is they are composed are not cells

To support the idea that all living things are composed of cells samples of many kinds of living things should be examined under a microscope to identify the presence of cells.

Explanation:

Cell theory states that all living beings are composed of cells. To prove this a thorough examination of a number of living beings under a powerful microscope is needed. Parts of all living things when observed under the microscope are found to be made up of smaller units called cells.

This examination helps to identify differences between plant cells and animal cells. It also gives an idea of the existence of unicellular organisms.  

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
