Nature of Science
What is science?
Science is an activity or process, the underlying aim of which is to further our own understanding of why
things happen the way they do in the natural or
created world.
What is the goal of science?
The creation of theory
What is biology?
The study of life
Name and explain the 3 types of bonds
Covalent: Sharing of an electron pair between 2 atoms
Ionic: one molecules get the electron that the other gave up
Hydrogen: partial charges, created do to uneven sharing of elections within the molecules, cause a small attractive force between other molecules with hydrogen
Explain the difference between a monomer and macromolecule and the alternate name for macromolecules.
A monomer is a single building block. Macromolecules are made from 2 or more monomers. Macromolecules are called polymers.
Describe the Biblical metanarrative and how it relates to science
Creation, fall, redemption, restoration
As Christians we can use knowledge from science to help improve the world helping with the restoration of creation.
We must understand our world to steward it well (creation stewardship mandate)
What makes a good hypothesis?
It must be testable and falsifiable
List the levels of organization of life
Atom, molecules, organelle, cell, tissue, organ or organ system, organism, population, community, ecosystem, biosphere
How does a polar molecule work?
Polar molecules have a slight charge at each end of
the molecule due to an unequal sharing of electrons.
List the 4 classes of biological molecules
Proteins, lipids, carbohydrates, and nucleic acids
Freebee! The mitochondria is the...
Powerhouse of the cell!
Explain the difference between a theory, a hypothesis, and a law
Theory: Broad explanation of a large set of set a observations backed testing and empirical evidence
Hypothesis: a proposed explanation or prediction, generally lacks evidence/support but it is Testable and potentially falsifiable
Law: describes what creation/nature does under certain conditions; generalizations related to the way some aspect of the natural world behaves under certain conditions. Often expressed in a mathematical representation
Explain homeostasis
Maintaining a constant internal environment to
continue the process of life. Regulate internal environment in response to environmental changes.
Explain how a buffer works
A buffer lessens the effect of an acid or a base that is added to a solution by absorbing the extra hydrogen (acids) or hydroxide (bases)
Backbones of phosphates and sugars (deoxyribose) with nitrogenous bases. The two strands are connected by hydrogen bonds between the nucleotides: forming a double helix.
Atheists: there is no room for the supernatural in explanation of the physical world.
Christians: God created the world.
This is an example of what:
Sadie Science is looking at the effect of Taylor Swift music on mental health. She notices a positive correlation between amount T Swift played in public and reports of mental health break downs
This is an example of ex post factor research design
List the four unifying theories of biology and explain
Cell Theory
Theory of Evolution
Theory of Heredity
Gene Theory
List the special properties of water for life.
Water functions as a universal biological solvent
Water has cohesion and adhesion
Water absorbs and holds heat
List the functional groups
Hydroxyl
Carboxyl
Amine
Phosphate
List the 6 aspects of science
Aspect #1: Science is characterized by its demand for empirical evidence for its conclusions.
Aspect #2: Science is characterized by its demand for logical reasoning.
Aspect #3: Science given tentative or contingent knowledge.
Aspect #4: Science has an epistemological framework which includes a set of presuppositions.
Aspect #5: Science as a Human activity has limits
Aspect #6: Science takes place within the values and norms of the culture and is subject to the biases of its practitioners.
Identify the control group, experimental group, treatment, independent variable, and dependent variable in this experiment: Harry Hypothesis wants to research the effect energy drinks have response time. He has 10 college student drink a cup of water each and then sit for 10 minutes. At a randomly selected point during the 10 minutes an alarm goes off and the students must react as fast as possible to hit a button to stop the alarm. The time from the alarm sounding to hitting the button is measured. He gives another 10 students each a cup of "Heart Problems In A Can Energy" and puts them through the same test.
Harry Hypothesis wants to research the effect energy drinks have response time. He randomly select
List the 6 shared properties of living things
Organisms are constructed of ... the same kinds of atoms/molecules, according to the same laws of energy.
Organisms consist of ... one or more cells
Organisms use ... energy and raw materials from the environment to survive & reproduce. Metabolism
Organisms sense and make controlled responses to the conditions in their external and internal environment to regulate Homeostasis
All organisms have the capacity to reproduce & pass genetic information to future generations from parents to offspring
Living organisms adapt to the environment
Explain and name how macromolecules and built and taken apart
Dehydration synthesis: 2 hydrogens and an oxygen are removed (to make a water) from the hydroxyl groups on the ends of 2 molecules. Molecules bonded together.
Hydrolysis: A water molecule is added to 2 molecules bonded to a single oxygen. Molecules are broken apart.
