1. which of the following statements is true?

1. which of the following statements is true? since all cells carry out cellular repiration, they contain mitochondria. a cell cannot be subdivided into smaller units that maintain the living state. plant cells contain chloroplasts and no mitochondria while animal cells contain mitochondria and no choroplasts the cells membrane's function is to prevent diffusion of any subatance into or out of the cell. 2. a biologist discovers a new unicellular organism and classifies it as a prokaryote. the cell is very small, contains a cell membranc, a cytoplasm, dna is a nucleus, and no other cell organelles. which statement below represents a correct response to the biologist's discovery and classification? the organism is a prokaryote, because it lacks cell organellessuch as mitochondria, golgi apparatus, andendoplasmic reticulum. the organism is a prokaryote, because it is so small and simple in structure. the organism is a eukaryote, because it has a nuvleus. the organism is a eukaryote, because it has a cell membrane, a cytoplasm, and dna 3. which structures are used by the cell for storing and maintaining biological information that will be passed to daughter cells when the cell divides? nucleus, chromatin nucleolus, ribosome vacuole, lysosome golgi apparatus, endoplasmic reticulum 4. what would most likely happen to cells placed in fresh water? water would flow out of them because they are hypotonic to the external environment water would flow into them because they are hypotonic to the external environment water would flow out of them because they are hypertonic to the external environment water would flow into them because they are hypertonic to the external enironment 5. why does photosynthesis require water? because water provides oxygen atoms because water provides electrons because water accepts protons because water acts as a catalyst 6. the following aquariums were set upwith the same volume of water. (elodea is an aquatic green plant.) aquarium 1: elodea only aquarium 2: elodea and an aquatic snail aquarium 3: aquatic snail only which aquariums will establish a cycle of carbon dioxide and oxgen gas flow if placed in the dark for several weeks? 1, 2, and 3 2 and 3 3 only none 7.which of the following are energy carrier molecules involved in photosynthesis? atp only atp and nadph atp, nadh, and fadh2 nadph, nada, and, fadh2 8. which of the following shows the correct order of events during cellular respiration? pyuvate oxidation, glycolysis, electron transport, krebs cycle glycolysis, krebs cycle, pyuvate oxidation, electron transport glycolysis, pyruvate oxidation, krebs cycle, electron transport pyruvate oxidation, krebs cycle, glycolysis, electron transport 9. how do the the quantities of atp formed during aerobic and anaerobic repiration compare? two times more atp is formed during aerobic respiration than during anaerobic respiration four times more atp is formed during aerobic respiration than during anaerobic respiration eight times more atp is formed during aerobic respiration than during anaerobic respiration eighteen times more atp is formed during aerobic respiration than during anaerobic respiration 10. wine is made by mixing yeast with grapes and allowing the yeast cells to undergo fermentation. sparkling wine is a type of wine that cantains high levels of dissoleved carbon dioxide. what is the sourse of the carbon atoms in the carbon dioxice found in sparkling wine? ethanol lactic acid methane glucose
