question
Explain how evolution bridges the concepts of unity and diversity in life
answer
Common ancestry, Diversity, and natural selection
question
Darwin's Theory of Evolution
answer
-biology's core theme which accounts for life's unity (seen in DNA and common genetic code) and diversity (seen in the three domains and many kingdoms)
-states that living species are descendants of ancestral species
- Proposed mechanism is natural selection based on the two observations of heritable variations in a population and overproduction of offspring and the two interferences of greater reproductive success of individuals best suited to the environment, which leads to gradual accumulation of evolutionary adaptations.
Oral cavity, pharynx, esophagus, stomach, small intestine, large intestine
question
Peristalsis
answer
muscular action propelling food through alimentary canal
question
Mechanical vs Chemical Digestion
answer
Mechanical- mouth, stomach. the breaking down of food physically through chewing and churning, making digestion easier
Chemical- stomach, small intestine. the breaking down of the food through chemical compounds, making it possible for body to absorb nutrients
question
Organ Systems
answer
Circulatory- Transports substances throughout the body
Integumentary- Protects body, includes nails
Reproductive- Produces gametes and offspring
Muscular- moves the body
Skeletal- Supports body and anchors muscles
Digestive- Breaks down macromolecules into nutrients; eliminates waste. includes the liver
Respiratory- Echanges oxygen and carbon dioxide between blood and air
Lymphatic/Immune- Defends against disease, includes spleen
Nervous- processes sensory information and controls responses
Endocrine- secretes hormones that regulate body activities
Urinary- rids body of certain wastes, includes kidney
