A new predator of rabbits has been introduced within an ecosystem. This new predator runs faster than the native predators of rabbits. 2 Which answer choice best describes a community? 3 Eight components
present in nucleic acids are listed in the box. 4 What would be the most likely effect of a wildfire that burned a large area of a forest? 5 Which four body systems interact to allow a person to sneeze? 6 Which cell that was viewed is most likely a prokaryote? 7 Based on this key, which two fish have eyes located on either side of their head and are not spotted? 8 Students are modeling mRNA during the process of protein synthesis. Which answer choice
correctly describes the model of the mRNA strand being transcribed? 9 The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle. What is a result of preventing spindle fibers from forming? 10 A team of students encounters an unknown organism in a field while conducting a biodiversity study. Some students think the organism is a plant, while others think it is a fungus. Which question should the students investigate to classify the organism correctly? 11 The San Marcos salamander, Eurycea nana, is a light reddish-brown translucent salamander about 2–5 cm in length. E. nana is found only in Spring Lake and a portion of the San Marcos River. 12 The data in the diagram is evidence that — 13 Which of these describes the similar functions of capsids and nuclear membranes? 14 Enzymes are proteins that have a three-dimensional shape that is specific to a particular substrate. Environmental conditions can change the shape of the protein. 15 Which description best identifies this
type of cellular transport? 16 Which selective pressure most likely resulted in the development of the aye-aye lemur’s special adaptation? 17 18 Gibberellins are hormones produced in the root tips of plants. The plant uses these hormones to stimulate the growth of shoots. 19 20 The populations
of which organisms will most likely increase as a result of a disease that suddenly reduced the population of Texas horned lizards? 21 Which statement provides the best explanation for the difference in
biomass of organisms found at each trophic level? 22 Conservation
biologists studying cheetah populations have determined that the lack of genetic diversity among the cheetahs is due to genetic drift. 23 CRISPR-Cas9 is a genetic modification technique that edits parts of the genome of an organism. Using this technique scientists can add, remove, or modify sections of the DNA
sequence. 24 During secondary succession, which of these best describes why decomposing pioneer plants give way to larger, more complex plants species, such as
hardwood trees? 25 Which two systems most directly interact in the fuzzy millipede’s defense against ants? 26 Based on
this pedigree, what are the most likely genotypes of individuals I-1 and I-2? G :(I-1: AA, I-2: Aa) 27 When cells lose their ability to regulate the cell cycle, they can divide at an accelerated rate and form a mass of cells. This mass of cells is referred to as — 28 Which type of mutation does the model demonstrate? 29 Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree
frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful. 30 In a study of physical endurance, researchers observed significant increases in the heart rates and breathing rates of participants immediately after they engaged in strenuous exercise. 31 In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce. 32 Based on the two diagrams, which list correctly identifies the relationships Glyptapanteles 33 Male guppies found in areas without predators are more colorful than the ones found in locations with large predator populations. A
population of adult guppies originating from an area with a large number of predators is transferred to a nearby area with few predators. 34 Grassland ecosystems in Texas have
evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a
prescribed burn. 35 Which system interactions are dependent on the plant’s ability to respond to the direction of light? 36 Exposure to the building material asbestos has been linked to certain types of cancers. Asbestos causes mutations in the p53 gene, which controls tumor suppression. Which statement best explains why people with cancer due to asbestos exposure do not pass the mutation on to their offspring? 37 Which of
these components are found in the cells of all living organisms? 38 Based on this diagram, which two systems interact to maintain homeostasis? 39 Which role of protists has the most positive effect on maintaining the plant population in an ecosystem? 40 Which list correctly matches the functions to the types of carbohydrates? 41 Gametes produced by an organism contain a combination of genes from that organism. In every gamete, this combination is — 42 What is the most likely explanation for white-tailed deer having a seasonal breeding cycle instead of a monthly breeding cycle like many domesticated animals? 43 Which of these is the correct complementary DNA strand for the segment
shown? 44 Which list describes the types of relationships the sunfish has with other marine organisms? 45 Which statement accurately describes the energy needs for photosynthesis and cellular respiration? 46 47 Which
statement is supported by this cladogram? 48 Some species of millipedes will roll into a ball when threatened, while other species of millipedes can
secrete noxious chemicals from their bodies. 49 Which of the following best explains why cells that contain the same genetic material
do not develop into the same types of cells? 50 Although these proteins have different specific functions, they all — Which statement provides the best explanation for the difference in biomass of organisms found at each tropic level?Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level? A Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
Which of these best demonstrates mutualism between certain types of bacteria and humans?Which of these best demonstrates mutualism between certain types of bacteria and humans? Intestinal bacteria obtain nutrients from the gut and produce vitamin K used by humans.
What would be the most likely effect of a wildfire that burned a large area of a forest Quizizz?What would be the most likely effect of a wildfire that burned a large area of a forest? More sugars and starches would be available for animals in the area. The availability of fossil fuels for use by industries in the area would be reduced.
What role of protist has the most positive effect on maintaining the plant population in an ecosystem?Which role of protists has the most positive effect on maintaining the plant population in an ecosystem? Protists are a major food source for animals.
