MTTC INTEGRATED SCIENCE
(SECONDARY) EXAM QUESTIONS WITH
CORRECT ANSWERS
Cardiac muscle - Answer-Strong, quick and continuously contracts involuntarily
More similar to skeletal muscle
Systolic blood flow - Answer-When the heart muscle contracts and pumps blood out
Diastolic blood flow - Answer-When the heart muscle relaxes and blood flows back in
3 possible cycles of reproduction - Answer-Haplontic - fungi, green algae, protozoa
Diplontic- animals, some brown algae, some fungi
Haplodiplontic - Plants and some fungi
4 Forms of Asexual reproduction - Answer-Budding - offspring start as a growth on
parent's body
Fragmentation - similar to budding but after maturation the individual fragments into
about 8 pieces (ex:worms)
Parthenogenesis - Known as a virgin birth, female produces eggs that develop w/o
being feritlized (ex: lizards, fish, insects, frogs)
Self-fertilization - species that have both male and female parts, hermaphroditic,
fertilization occurs w/in the individual
Stages of embryonic development - Answer-Zygote - diploid cell formed by fusion of two
gametes
Morula - ball-like mass of 16-32 cells formed by mitotic divisions of the zygote
Blastula - hollow ball-like structure, attaches to side of uterus
Gastrula - formed cells migrate to the center of the blastula
Bryophyta plant division characteristics - Answer-mosses and liverworts, only
nonvascular plants, do not have xylem to transport water, live in moist places, have root
like parts called rhizoids
Vascular plant characteristics - Answer-Have true roots, stems, leaves, and xylem.
Pteridophytes - Answer-Plants that use spores and not seeds to reproduce, need water
to reproduce. Includes Psilophyta (whisk ferns), Lycophyta (club mosses), Sphenophyta
(horsetails), Pterophyta (ferns)
Graticule slide - Answer-marked with grid line, useful for counting or estimating a
quantity
, Preparing acid solutions - Answer-Always add acid to 2/3 water, then add rest of water
# of Animal species - Answer-over 1 million species and about 30 divisions
# of insects - Answer-800,000 species, half of animal kingdom
Characteristics of animal kingdom - Answer-muliticellular, heterotrophic, reproduce
sexually, do not have cell walls or chloroplasts, can move at some stage of life, can
rapidly respond to environment due to specialized tissues like nerve and muscle
Heterotrophic - Answer-method of getting energy by eating food that has energy
releasing substances
Mendel - Answer-Father of genetics, experimented with pea plants to observe inherited
traits
McClintock - Answer-Created the first genetic map for maize, demonstrated
recombination, how transposition flips the switch for traits.
Watson and Crick - Answer-Discovered the structure of DNA double helix and helped
explain how DNA replicates.
Leeuwenhoek - Answer-First to observe single celled organisms with homemade
magnifying glass. Observed bacteria, yeast, plants and other microscopic organisms.
Linnaeus - Answer-Created a method of classifying plants and animals, a way to
organize and study large amounts of data, called Linnaean taxonomy.
Darwin - Answer-natural selection, survival of the fittest by observing finches. Also
discovered fossils, noted stratification, dissected marine animals and interacted with
indigenous peoples.
Scientific fact - Answer-an objective and verifiable observation
Scientific theory - Answer-greater body of accepted knowledge, principles, relationships
that might explain a fact.
Hypothesis - Answer-Educated guess that is not yet proven. Used to predict the
outcome of an experiment
Law - Answer-An explanation of events that always leads to the same outcome.
Model - Answer-Used to explain something on a smaller scale or in simpler terms.
Scientific Method - Answer-Identify a problem
Formulate a hypothesis
