Scientific Method is
The process of science
1st step in scientific method:
Observation
2nd step in scientific method:
Asking a question
3rd step in scientific method:
Formulating a hypothesis (tentative explanation)
4th step in Scientific method:
Perform the experiment
5th step in scientific method:
Gather results of the data
6th step in scientific method:
Draw a conclusion
What is a Hypothesis?
is a tentative explanation
What is the basic unit of every living thing?
The Cell
what are the 3 major kingdoms?
Monera, Protista, Fungi, Plantae, and Animalia
what are the biological organization?
Atoms > Molecule > Cell > Tissue > Organ > Organism > Population > Community > Ecosystem > biosphere
what is a control in an experiment?
independent variable that remains the same
What is DNA's properties?
It has a nitrogenous base that is made up of: Adenine (A), Guanine (G), Thymine (T), Cytosine (C),
how is DNA always paired?
A-T, T-A, C-G, G-C
Organisms in the plant kingdom are:
Photosynthetic
What is the difference between theory and Hypothesis?
A theory is a based upon a hypothesis and backed by evidence, and hypothesis is a proposal intended to explain certain facts or observations.
what is the definition of population?
a group of organisms of one type that live in the same area
what are examples of ecosystems?
Coral reef, Rain forest,
what are the four most common elements in living things?
CHON (Carbon, Hydrogen, Oxygen and Nitrogen)
what percentage of living things are made up of CHON (Carbon, Hydrogen, Oxygen and Nitrogen)
96%
what is a compound?
Two or more atoms/elements joined together chemically, with covalent or ionic bonds.
What is a molecule?
A molecule is formed when two or more atoms join together chemically.
(Note: All compounds are molecules but not all molecules are compounds.)
What is a acid
An acid is any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water
Example: Hydrochloric acid (HCI)
What is a base
a base is most commonly thought of as an aqueous substance that can accept hydrogen ions
what is the atomic number of an atom?
The number of protons in an atom is the atomic number
What is the mass number of a atom?
Number of Protons + Number of Neutrons
Which bond is strongest
The covalent bond
Which bond is weakest?
the hydrogen bond
what is a solvent?
a liquid substance capable of dissolving other substances
What is a solute?
the dissolved matter in a solution
What is hydrophilic?
Hydrophilic, or 'water loving' refers to molecules that are easily miscible in water.
What is hydrophobic?
It can either refer to a person who is unreasonably afraid of water or something that repels water and doesn't mix well with it.
what is the process of denaturation ?
process in which proteins or nucleic acids lose their tertiary structure and secondary structure by application of some external stress or compound.
Example: a egg incubated and a egg fried.
what is hydration reaction ?
a chemical reaction that involves the loss of water from the reacting molecule
what is hydrolysis?
hydrolysis is the addition of one or more water molecules to another molecule, usually to create two different compounds.
KINGDOM MONERA?
are single-celled organisms that don’t have a nucleus. Bacteria make up the entire kingdom. There are more forms of bacteria than any other organism on Earth.
KINGDOM PROTISTA?
are mostly single-celled organisms that have a nucleus. They usually live in water. Some protists move around, while others stay in one place. Examples of protists include some algae, paramecium, and amoeba.
KINGDOM FUNGI?
are usually motionless organisms that absorb nutrients for survival. They include mushrooms, molds, and yeasts
KINGDOM PLANTAE ?
are multicellular, have nuclei, do not move. Examples: multicellular algae, mosses, ferns, flowering plants (dandelions, roses, etc.), trees.
KINGDOM ANIMALIA?
are the most complex organisms on Earth. Animals are multi-celled organisms, eat food for survival, and have nervous systems. They are divided into vertebrates and invertebrates and include mammals, amphibians, reptiles, birds and fish.
What are the properties of life?
1.) Growth
2.) Ability to reproduce
3.) Homeostasis
4.) Organization
5.) Matablolism
6.) Adaption
7.) Response to stimuli
Nucleic Acid?
Nucleic acids are very large molecules that contain hundreds of amino acids and sugars. DNA and RNA would be examples.
Proteins ?
molecules composed of polymers of amino acids joined together by peptide bonds. It can be distinguished from fats and carbohydrates by containing nitrogen. examples are Insulin and Hemoglobin
Lipids?
anything that dissolved in an organic solvent. Lipids could be fats, oils, some vitamins, and waxes
Monosaccharide ?
Monosaccharide is a simple sugar. They serve as building blocks for more complex carbohydrate forms.
Some important monosaccharides include: Glucose, Fructose, and Galactose
Disaccharides?
are a group of sugars composed of two monosaccharide groups linked together through the loss of sugar. Some important disaccharides include:Maltose, Lactose, and Sucrose
Polysaccharides?
are complex carbohydrates composed of numerous monosaccharides combined through the loss of water molecules. Examples include starch and Glycogen
What are the four macromolecules of lie?
Carbohydrate, Lipids, Nucleic acid, and Protein.
Carbohydrate
are any of a group of organic compounds that includes sugars, starches, celluloses. They serves as a major energy source in the diet of animals.
what are four unique properties of water?
1. Cohesion: is the sticking together of similar molecules
2.Surface Tension: cohesion allows water to pull together and form droplets or form an interface between it and other surfaces
3.Adhesion: The sticking of one substance to another. Water is a good adhesive. It will cling on to many objects and act as a glue
4. High boiling point and low freezing point.
Ph scale for acid?
0-7 = Acids on Ph scale
What acid is known as HCI
Hydrochloric acid
