BIOL 1407
General Biology II
A chemistry review to start: how atoms bond, and the organic molecules they build. Then animal form and function: tissues, signals, homeostasis, thermoregulation and energy budgets; hormones and how they reach and change their target cells; insect metamorphosis; the ovarian and uterine cycles; digestion, from the first bite to absorption; circulation through the heart, blood vessels and blood; gas exchange and the control of breathing; and water balance, nitrogenous wastes and the kidney. More of the course will follow.

Chemical Bonding Lab
Build atoms shell by shell, then share, transfer and tug on electrons with Bohr models. Seven guided stations run from energy shells to covalent, ionic and hydrogen bonds, and the Van der Waals grip that holds a gecko to glass.
Playable nowMacromolecule Builder
Build the four macromolecule classes from real skeletal structures. Guided lessons take you through dehydration synthesis and hydrolysis one bond at a time.

BIOL1407 Unit Exam III Ch40: Introduction to Anatomy & Physiology
Review what we did in class by doing it yourself: race shapes through a water tunnel, soak cubes in dye, match and apply tissue concepts, send a nerve impulse against a hormone, run a thermostat, fluff a sparrow’s feathers, and follow a hummingbird through a cold night.
Playable nowBIOL1407 Unit Exam III Ch45: Hormonal Communication
Send a signal down all five pathways: endocrine, paracrine, autocrine, synaptic and neuroendocrine. Find out why serotonin and dopamine are named by their route, not their molecule, sort hormones into polypeptides, amines and steroids, and compare ductless endocrine glands with ducted exocrine glands and hormones with pheromones.
Playable nowBIOL1407 Unit Exam III Ch45: Hormone Polarity & Signal Transduction
Take water-soluble epinephrine and lipid-soluble estradiol to the membrane, run the GPCR, cAMP and PKA cascade and the steroid route to DNA, then see how one hormone does three different jobs in the liver, muscle vessels and gut vessels.
Playable nowBIOL1407 Unit Exam III Ch45: Insect Development & Metamorphosis
Fire an ecdysteroid pulse with juvenile hormone high and low, follow the hormone curves from larva to pupa to adult, and trace both signals back to the brain, PTTH and the glands that make them.
Playable nowBIOL1407 Unit Exam III Ch46: Ovarian & Uterine Cycles
Build the control chain from hypothalamus to pituitary to ovary and uterus, run the ovarian cycle through the LH surge and the corpus luteum, build and shed the uterine lining, line the two cycles up, and work through three what-if cases: pregnancy, menopause and the combination pill.
Playable nowBIOL1407 Unit Exam IV Ch41 Part 1: Animal Nutrition — Following a Meal
Follow one meal from mouth to anus: label the digestive tract, flip the switches of the swallowing reflex, squeeze a bolus down the esophagus, turn pepsinogen into pepsin, move sugars, amino acids and fats into a villus, send the blood past the liver, and see what the colon, a cow’s rumen, gut microbes and digestive hormones add.
Playable nowBIOL1407 Unit Exam IV Ch42: Circulation — Heart, Vessels & Blood
Race diffusion over longer distances, compare open and closed systems, and send a blood cell around a fish, a frog and a mammal. Then label a heart and run one heartbeat, watch blood slow down in the capillaries and climb back up the leg, and follow a clot and a plaque as they form.
Playable nowBIOL1407 Unit Exam IV Ch42: Partial Pressure & Gas Exchange
Calculate the partial pressures of O₂ and CO₂ in air, watch each gas diffuse down its own gradient, send blood through the lungs and the body tissues, hold your breath and breathe again, then see how CO₂ and pH control breathing and why air with extra CO₂ is dangerous.
Playable nowBIOL1407 Unit Exam IV Ch44 Part 1: Osmoregulation & Nitrogenous Wastes
Make water move between two solutions, drop red blood cells into three solutions, keep a marine and a freshwater fish in water and salt balance, test a seabird’s salt gland, choose ammonia, urea or uric acid for three animals, and run the urea cycle.
Playable nowBIOL1407 Unit Exam IV Ch44 Part 2: Excretory Systems & the Kidney
Filter, reclaim, secrete and excrete; compare protonephridia, metanephridia and Malpighian tubules; label the kidney and the nephron; send filtrate down and up the loop of Henle; and run the ADH and renin–angiotensin–aldosterone responses.
