(1) What are the general characteristics of all living things?
|
1) Living things are highly ordered.
2) All living things have cells 3) All living things use energy from their environment 4 All living things respond to stimuli 5) Living things develop. 6) Living things reproduce themselves 7) Living things contain genetic information |

What is a hypothesis? What is its role in the Scientific Method?
|
A hypothesis is a proposed explanation for a set observations
Most scientists use hypothesis driven science. |
|
|
(3) So what is an atom made of?
|
An atom is made up of three subatomic particles, A Neutron containing a neutral charge, a Proton containing a positive (+) charge, and an Electron containing a negative charge (-) . The nucleus contains the proton and neutron, while the electron(s) float in their appropriate electron shell(s).
|
|
|
(4) Be sure you are able to explain and predict how atoms chemically bond together to make molecules, in relation to the unfilled outer electron shell.
|
The number of electrons in the outermost shell depict how an atom is going to behave chemically. Chemical reactions enable atoms to give up or acquire electronics, thereby completing their outer shells. Electrons do this by either transferring or sharing outer electrons.

(19) Describe the basic structure of DNA? What are the monomers of nucleic acid?
|
The basic structure of DNA is through nucleotide monomers, these monomers consist of a pentose sugar, either deoxyribose in DNA, and ribose in RNA; a phospate ion, and a nitrogenous base.
The pentose sugar covalently bonds with the phospate group resulting in a sugar-phosphate backbone, with the nitrogenous bases hanging off like appendages. In a DNA molecule there are two polynucleotides wrapped around each other in a double helix. At the core of the helix, the bases match through hydrogen bonding. The functional groups of the bases make the matching specific, Adenine to Thymine and Guanine to Cynsine |

|
(9) Be able to explain anabolism, catabolism, condensation synthesis, and hydrolysis.
|
Anabolism
Is the set of molecular pathways that construct molecules from smaller units Catabolism The set of metabolic pathways that break down large molecules into smaller units Hydrolysis Adding a molecule of water to split a larger molecule into smaller units Dehydration Synthesis Chemically bonding two monomers into a polymers by removing a molecule of water between corresponding functional groups. |

|
Epithelial tissue comes from all of the germ layers
|
-Cuboidal - cube like
-Columnar column like cell -Squamous flat like cells -Lies on top of connective tissue -This tissue creates Epidermis, the outer layer of skin. |
|
|
Connective Tissue
|
Sparse population of cells scattered through an extra cellular matrix, the cell makes this matrix
Loose Connective Tissue -Keeps your cheek connected, its matrix consists of proteins and collagen fibers Adipose Tissue (Fat) -Fibrous connective tissue has a dense matrix (Joints, Ligaments, Tendons(attach muscle to bone) Cartilage - Matrix is strong but flexible (acts as a boneless skeleton) -No blood vesells |
|
|
Muscle Tissue(Contractile)
|
All muscle onsists of bundles of long, thin, cylindrical cells called muscle fibers.
Skeletal Muscle (Voluntary) -Attached to bone by tendons -Striated Cardiac Muscle (Involuntary) -Muscle that is attached to the heart, (Intercolated Disks that promote Synchronized pulsating) -Striated Smooth Muscle (Involuntary) -In the stomach Function : To contract, either voluntary or involuntary |
|
|
Nervous Tissue
|
-Found in Brain and Spinal Cord
Consits of Neruons -Dendrites act as branches on a tree, picking up information -Axon acts as the wire, sending it to the Synapse -Special coating called Myolin -Synapse is the control center |
