Molecules may be assembled into a microscopic structure called a(n)____________ which
carries out specific functions within a cell - verified answers; organelle
The simplest level of organization that can carry out all of the functions of life is a(n) - verified
answers; cell
A ___________ is a group of similar cells that act as a functional unit. - verified answers;
tissue
Your brain is an example of a(n) - verified answers; organ
A group of organisms that belong to the same species and live in the same place is called a(n)
- verified answers; population

ecosystem
Which of the following are correct statements about the hierarchy of complexity in Biology?
A) Simple structures combine and interact to form more complex structures.
, B) New characteristics referred to as "Emergent Properties" develop due to the interactions of
structures at each level of organization.
C) Cells are an example of the most complex structures and interactions in the scale of simple
to complex. Nothing in the Hierarchy is more complex than a single cell.
D) Cells are the simplest structures that possess all of the characteristics by which we define
living organisms.
E) Organisms of the same type living in the same geographic area a called a population.
F) Organelles are structures that perform particular functions within a cell.
G) Organ systems do not possess the characteristics of being alive. - verified answers; A, B, D,
E, F

2.Formulate a falsifiable hypothesis.
3.Make a prediction.
4.Design and carry out an experiment.
5.Analyze data
6.Form a conclusion that supports or rejects the hypothesis.
