Review Flashcards
What do animals have in common?
All animals are multicellular and heterotrophic.
What distinguishes a moss from a chlorophyte?
Chlorophyte only have a single called embryo (unicellular) , and mosses have multicellular embryos.
What distinguishes a jelly fish (Cnidarian) and a squid (Mollusks)?
Cnidarians have radial symmetry and no organs, and Mollusks have bilateral symmetry and has organs.
What are true about all plants?
All plants are eukaryotic, have chlorophyll a and b, and have cellulose cell walls.
Best describes the rate of population growth.
The slope of the population size versus time graph at any point in time.
Which of the following describes exponential growth?
The slope of the population size versus time graph is proportional to population size.
What describes logistic growth?
Influenced by the difference between carrying capacity and population size.
What do Chordates have in common?
All chordates are are eukaryotic and heterotrophic and deuterostomes (mouth develops second).
What best distinguishes the Gymnosperms and Angiosperms from the other members of the plant kingdom that you studied?
Gymnosperms and Angiosperms make seeds, and the others do not.
Which of the following characterizes alternation of generations?
Sporophyte produce spores by way of meiosis, and gametophyte produce gametes by way of mitosis.
What are the characterize all animals?
Eukaryotic cells, multicellularity, and heterotrophic nutrition.
Real populations rarely reach a state of Hardy-Weinberg equilibrium. What explains this observation?
Reproductive success is dependent upon the genotype of each organism.
Which property below would best split 1. Philodina 2. Squid 3. Mouse
Coelomic status; philodina has a pseudocelom, and the squid and mouse have coeloms.
What type of population growth is the rate of the growth independent of population size?
Linear
The frequency of the “A” allele is 0.7 and the frequency of the “a” allele is 0.3. How do you calculate AA?
(0.7)(0.7) = .49
