NADP+ segments of DNA that are not part of the gene are called introns which of the following is not true of ribosomes they bind only one type of amino acid which part of an operon is incorrectly matched with its function? regulator--binds to the repressor protein cells of the ground tissue system are called parenchyma, collenchyma, and sclerenchyma cells which of the following is not true about the cohesion-tension model of water transport? water is transported in the phloem the protective sheath that first surrounds the shoot is called the coleoptile which of the following plant hormones prevents senescence and can initiate leaf growth? cytokinin BIO 101 FINAL Exam Questions and Answers With 100% Correct Solutions 2024 Graded A+ | STRAIGHTERLINE when you pick a bouquet of anther-less flowers, you have picked female gametophytes retained within the body of sporophytes which of the following is not a characteristic of a somatic embryo? these are genetically quite diverse phylogeny refers to the evolutionary history of a species which type of organism will form endospores when faced with unfavorable environmental conditions? bacteria bacterial cells pick up free pieces of DNA from the medium pieces that were released from dead bacteria in a process called transformation what feature enables the archaea to survive in harsh environments? their plasma membranes and cell walls the archaea include all of the following except lichens biological evolution differs from chemical evolution in that biological evolution would have been possible only after the development of a membrane the central dogma of genetics states that DNA directs protein synthesis and that information flows from DNA-RNA-protein although microbes are often equated with pathogens, not all are pathogenic and some help humans maintain their health. Which of the following are synthesized by bacteria that live in the human intestine? vitamins K and B12 a member of the green algae is chlamydomonas at one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to saprotrophy to gain food. Why is this no longer considered a solid theory? fungal cell walls contain chitin rather than cellulose an example of a colonial green alga is volvox a unicellular alga that has both plant-like photosynthesis and animal-like motility is a(n) dinoflagellate Crustose, fruticose, and foliose obtain their nutrients from photosynthetic cells contained within their middle layer. These are varieties of lichens spirogyra practice a type of sexual exchange called conjugation the function of endosperm is to provide nutrients to the embryo the site of formation of pollen grains is in the stamen seeds contain all of the following except a pollen grain which of the following statements is not true about alternation of generations life cycle? the sporophyte generation produces spores by mitosis in structures called sporangia double fertilization in an angiosperm produces a diploid zygote and a triploid endosperm a major evolutionary trend among plants is a reduction in the size of the gametophyte and an increase in the size of the sporophyte what systems do the cnidaria have that sponges lack? nervous fertilization in the earthworm is accomplished by the use of the clitellum which statement about sponges is not correct? sponges are thought to be at the base of the evolutionary tree, leading to more complex animals such as corals and worms which description best fits the lophotrochozoa? as embryos, they have three germ layers that will develop into the organ level of organization as adults an insect circulatory system is best described as an open system that mostly washes hemolymph "blood" through the hemocoel ascaris is considered to be a(n) roundworm the segments of a tapeworm consisting primarily of eggs, which hang in bags as a long chain behind the head are called proglottids If you play with a living anemone with a probe, it will withdraw even if you vibrate the probe like prey would vibrate; it also withdraws if you just add sugar. However, it reaches out and grasps an object that both vibrates and tastes like food. The use of such a double system prevents unnecessary firing of expensive nematocysts. Why are nematocysts "expensive"? The nematocyst is very complex and most likely costs the anemone much energy to build. a sponge actually feeds by the beating of the flagella of collar cells, forming a current; food is absorbed by collar cells which of these is not a characteristic of sponges? water enters through a single cavity, the osculum a hydra moves via muscle and nerve fibers which of the following is generally not a characteristic of all animals? animals range from unspecialized single-celled to specialized multicellular forms EMAIL ME: EMAIL ME: which difference distinguishes protostomes from deuterostomes? their embryonic development is different which of the following is not a characteristic of echinoderms? locomotion by muscles which statement is not true about echinoderms? the exoskeleton is made up of bony tissue which statement is not true about invertebrate animals? invertebrates lack a nervous system which of the following characteristics is not true about deuterostomes? they include the simplest of invertebrates which of the following organisms are considered advanced invertebrates with a true coelom? earthworms which of the following organisms show the typical method of acquiring food that is found in animals? earthworms, ennelids, who feed on any available organic matter that they can take into their mouths which type of animal symmetry produces mirror images of each other no matter how the animal is slices longitudinally radial symmetry both echinoderms and chordates are deuterostomes. this means that they have a similar development in their embryonic stage EMAIL ME: EMAIL ME: which feature distinguishes birds from the rest of reptiles? endothermic the most primitive primates are considered to be the prosimians which of the following sequences correctly represents vertebrate evolution? jawless fish-- lobefinned fish-- amphibians-- reptiles-- mammals the respiratory advantage provided by a four chambered heart over a three-chambered heart in vertebrates is separation of oxygen-rich blood and oxygen-poor blood which of these is not a true statement all chordates are vertebrates the jawless fish that is parasitic, attaching itself to and sucking fluids from the tissues of a living fish, is the lamprey which type of embryos have extraembryonic membranes? mammals nonvertebrate chordates, tunicates, and lancelets, differ from other chordates in that the notochord of nonvertebrate chordates does not become a vertebral column
