BIOL 1120

These notes cover the key concepts from Chapters 26, 33, 35, and 36 in BIOL 1220. They are organized, easy to follow, and written in clear language that makes studying faster and less stressful. Each chapter includes important definitions, diagrams, summaries, and examples that helped me earn high grades in the course. These notes are perfect for review before exams, catching up on missed material, or understanding the main ideas without digging through long textbook chapters.

There are four levels of analysis for questions addressing animal behavior. Animals make behavioral choices that enhance their energy gain and reduce their risk of becoming prey. Mating behaviors reflect the costs and benefits of parental investment and sexual selection. There are advantages and disadvantages to living in groups.

Land animals had to solve the same problems that plants faced when they moved to land: water conservation, gas exchange, reproduction and dispersal and the fact that water no longer buoyed them up against the pull of gravity The diversification of vertebrates was driven by the evolution of the jaw and limbs. Vertebrates have adapted to life on land as a result of the evolution of tetrapod limbs and an enclosed amniotic egg that allows embryonic development outside a body of water. Mammals and...

Kinds of Animals and the evolution, diversity, base body plans including tissues and organs, Porifera, symmetry, the evolution of the nervous system, early development, cnidaria

Fungi are eukaryote heterotros that feed by absorption Fungi reproduce both asexually and sexually and disperse by spores Fungi play important roles in nutrient recycling, ecological interactions, and human welfare

Adaptations, phylogenetic tree, evidence of plant evolution from green algae, evolutionary trends, transition from water to land, reproduction; for vascular and non vascular plants

Demonstrates the developmental specializations of bryophytes, ferns, gymnosperms, and angiosperms

Simple web to practice the lifespan/reproduction of a Gametophyte

1. The Tree of Life – 3 domains 2. Archaea and bacteria each contributed to the evolution of eukaryotes 3. The endosymbiotic hypothesis proposes that the chloroplasts and mitochondria of eukaryotic cells were originally free-living bacteria. 4. The paradox of sex – why did sex evolve and why is it maintained 5. Evolution of multicellularity – how does complex multicellularity differs from simple multicellularity 6. Diversity in protists including body plan, locomotion, nutrition, inte...

Describes multi-aspects of multicellularity and slime molds including: the phylogenetic tree, social ability, growth, specialization/organization, and evolution
