KSU Bio 198 Exam 7 Actual study with
Questions and correct/verified Answers
Characteristics of an animal - ANSW-Multicellular, heterotrophic, aerobic metabolism, no cell walls,
sexual reproduction, and motile
Bilateral Symmetry - ANSW-Has a left and right side
Radial symmetry - ANSW-Around an axis and has multiple planes
Asymmetry - ANSW-No organization
Germ Layers - ANSW-Endoderm (inside), mesoderm, ectoderm (outside)
Endoderm - ANSW-Inside layer where intestines and internal organs are derived
Mesoderm - ANSW-Middle layer where muscles and bones are derived
Ectoderm - ANSW-Outside layer where skin and nervous system is derived
Coelom - ANSW-A body cavity that is lined by tissue derived from the mesoderm
Body cavity - ANSW-A fluid filled space around the internal organs
Advantages of a coelom - ANSW-Allows animals to evolve more complex internal structures and be more
flexible in their movement
Segmentation - ANSW-Allows independent movement of body parts
Cephalization - ANSW-Development of a head structure
Tissues - ANSW-Layers of cells that all have the same structure and functions
Muscles types - ANSW-Smooth, skeletal, cardiac
Smooth muscle - ANSW-No striations, single nuclei, involuntary movement
Skeletal muscle - ANSW-Has striations, many nuclei, voluntary movement
Cardiac muscle - ANSW-Has striations, single nuclei, involuntary movement
Function of epithelial tissue - ANSW-Protection, secretion, absorption
Epithelial tissue - ANSW-Covers the outside of organs and structures insides the body (skin)
Types of epithelial tissue - ANSW-squamous, cuboidal, columnar
Squamous epithelial cells - ANSW-flat, irregular round shape
Cuboidal epithelial cells - ANSW-Cube shaped
Columnar epithelial cells - ANSW-tall and narrow
Function of connective tissue - ANSW-Protection and support of tissues and organs
Examples of connective tissue - ANSW-adipose, blood, bone, cartilage
, Function of nervous tissue - ANSW-send signals throughout the body and is responsible for coordination
of many functions in response to stimuli
Examples of nervous tissue - ANSW-neurons and neuroglia
Neurons - ANSW-Collect, process, and send information to all parts of the body
Neuroglia - ANSW-Support, protect, and maintain homeostasis around neurons
Homeostasis - ANSW-The maintenance of internal conditions
Negative feedback - ANSW-A change in the opposite direction
Positive feedback - ANSW-A change in the same direction (increases the change)
Incomplete digestive system - ANSW-Only one opening, ingested food and excreted waste products pass
thru the same opening
Complete digestive system - ANSW-Two openings, food goes in one and waste goes out the other
Components of the digestive system - ANSW-Mouth, salivary glands, esophagus, stomach, small
intestine, pancreas, liver, large intestine
Function of digestive system - ANSW-Digestion and absorption of molecules needed to maintain cellular
functions
Where is fat digested? - ANSW-Small intestine
Where is bile found? - ANSW-It is produced by the liver and stored in the gall bladder
Function of bile - ANSW-Assists in the digestion of fats
Vitamins vs Minerals - ANSW-Vitamins organic, minerals inorganic
Vitamins are water and fat soluble
Vitamins come from body, minerals come from food
Herbivores - ANSW-Plant based
Carnivores - ANSW-Eat other animals only
Omnivores - ANSW-Both plants and animals
Function of respiratory system - ANSW-Deliver oxygen to cells of body's tissue and remove carbon
dioxide
Main structures of the respiratory system - ANSW-Nasal cavity, trachea, lungs
Function of circulatory system - ANSW-Move oxygen throughout the body so it can be used to make
energy
Respiration vs Breathing - ANSW-Respiration is a cellular process and breathing is an organismic process
What two systems work together to create gas exchange? - ANSW-Respiratory and circulatory
Main transportation of oxygen - ANSW-Hemoglobin
