CYPRESS BIO 101 EXAM 4
How do autotrophs and heterotrophs differ in gaining energy and carbon? - CORRECT
ANSWER-Heterotroph: energy-consuming other cells; carbon-consuming other cells.
Autotroph: energy-sun 🌞Carbon-CO2
Why were the first bacteria probably heterotrophs? - CORRECT ANSWER-The process
is easy. No pigments, no electron transport needed. As long as their is "food" to
consume
What was the condition on earth around 3500 mya - CORRECT ANSWER-No O2
There was H2O, H2, NH3, and H4 but no simplex organic molecules
(Water, hydrogen, ammonia and methane)
Domain bacteria have this unusual molecule in their cells walls - CORRECT ANSWER-
Peptidoglycan
The domain eukarya diverged from prokaryotic ancestors and all the eukarya possess -
CORRECT ANSWER-Eukaryote cells
How are eukaryotic and prokaryotic cells similar? - CORRECT ANSWER-Cytoplasm,
ribosomes, DNA &RNA, glycolysis/ATP, reproduce
Bacteria and archaea - CORRECT ANSWER-Are two of the three domains of life
How do bacteria and archaea reproduce? - CORRECT ANSWER-Binary fission: one
parent makes two daughter cells
Heterotroph - CORRECT ANSWER-"Other feeder", not photosynthetic, consumer
Autotroph - CORRECT ANSWER-"Self feeder", photosynthetic, producers
Only eukaryotes have - CORRECT ANSWER-Organelles (nucleus, mitochondria)
(chloroplasts in some), complete cellular respiration, mitosis, meiosis, sexual
reproduction
What are the names of the three kingdoms of eukarya which are not Protists? -
CORRECT ANSWER-Fungi, plants, animals
, The largest prokaryote cell is about - CORRECT ANSWER-10um
Bacteria and archaea - CORRECT ANSWER-Genes of archae have intones, but genes
do not
Endosymbiosis - CORRECT ANSWER-Have a circular chromosome of DNA
How and when did animals evolve? - CORRECT ANSWER-In ocean, probably from
heterotrophic colonial Protists about 900 million years ago
What is an animal - CORRECT ANSWER-Multicellular eukaryote
Ingestive heterotroph. Eat, take food into body and have digestive tract
Motile, can move at least during one stage of life
No cell walls, increase flexibility and movement
Sexual reproduction, sperm must get to the egg
Cephalization - CORRECT ANSWER-Major evolutionary trend. Anterior contains
increasing amount of brain and sensory organs
Chordates - CORRECT ANSWER-Most highly developed animals with several
advanced features (bilateral, complex organs, strongly segmented, highly cephalized)
All have a dorsal, hollow nerve cord (spinal cord)
Vertebrates - CORRECT ANSWER-Sub-phylum of Chordates with a skull and vertebrae
Amphibians - CORRECT ANSWER-First vertebrates on land but are only partially
adapted to life in a drying environment
Somewhat like fish with legs
Must go back to water regularly
External fertilization
Reptiles - CORRECT ANSWER-Snakes, lizards, dinosaurs, turtles
Better adapted to land than amphibians and diverged from an amphibian ancestor
How do reptiles differ from amphibians - CORRECT ANSWER-Skin covered with water
proof scales made of the structural protein keratin (water proof)
Internal fertilization
Amniotic egg: resists drying out, filled it's nourishing yolk. After fertilization, is payed on
land and protects the embryo until hatches
Dominant terrestrial animals until about 65 million years ago when replaced by birds
and mammals
Amniotic egg - CORRECT ANSWER-New type of water proof membrane which
surrounds the embryo
Birds - CORRECT ANSWER-Share a common ancestor with dinosaurs
