Q: What are small organelles and are the site of protein synthesis called. Read this paragraph and choose the correct option from the provided answers: Ribosomes are small organelles and are the site of protein synthesis. They are found in all cells. Choices: - chromosomes - chloroplasts - chromosomes - ribosomes A:
ribosomes

Q: What makes up the core of the endoskeleton? Read this paragraph and choose the correct option from the provided answers: The main distinguishing feature of vertebrates is their vertebral column, or backbone (see Figure below ). The backbone runs from the head to the tail along the dorsal (top) side of the body. The vertebral column is the core of the endoskeleton. It allows a vertebrate to hold its shape. It also houses and protects the spinal (nerve) cord that passes through it. The vertebral column is made up of repeating units called vertebrae (singular, vertebra). In many species, there are shock-absorbing discs between the vertebrae to cushion them during movement. Choices: - dermis - notochord - thorax - vertebral column A:
vertebral column

Q: Q: The reverse process of moving material into a cell is the process of what? Read this paragraph and choose the correct option from the provided answers: Exocytosis The reverse process of moving material into a cell is the process of exocytosis. Exocytosis is the opposite of the processes discussed above in that its purpose is to expel material from the cell into the extracellular fluid. Waste material is enveloped in a membrane and fuses with the interior of the plasma membrane. This fusion opens the membranous envelope on. Choices: - endocytosis - proteolysis - osmosis - exocytosis A:
A: exocytosis

Question: Q: Why does the body react to a loss of chloride ions? Read this paragraph and choose the correct option from the provided answers: Chloride ions are important in neutralizing positive ion charges in the body. If chloride is lost, the body uses bicarbonate ions in place of the lost chloride ions. Thus, lost chloride results in an increased reabsorption of bicarbonate by the renal system. Choices: - increased tricarbonate reabsorption - decreased bicarbonate reabsorption - decreased tricarbonate reabsorption - increased bicarbonate reabsorption A:
Answer: increased bicarbonate reabsorption

Q: What kind of container is used to measure heat changes during a chemical reaction or physical process? Read this paragraph and choose the correct option from the provided answers: Calorimetry is the measurement of the transfer of heat into or out of a system during a chemical reaction or physical process. A calorimeter is an insulated container that is used to measure heat changes. The majority of reactions that can be analyzed in a calorimetry experiment are either liquids or aqueous solutions. A frequently used and inexpensive calorimeter is a set of nested foam cups fitted with a lid to limit the heat exchange between the liquid in the cup and the air in the surroundings (see Figure below ). In a typical calorimetry experiment, specific volumes of the reactants are dispensed into separate containers and the temperature of each is measured. They are then mixed into the calorimeter, which starts the reaction. The reactant mixture is stirred until the reaction is complete, while the temperature of the reaction is continuously monitored. Choices: - hydrostatic - thermal flask - graduated cylinder - calorimeter A:
**Answer**
calorimeter

Q: Q: The external female reproductive structures are referred to collectively as what? Read this paragraph and choose the correct option from the provided answers: The external female reproductive structures are referred to collectively as the vulva. They include the labia (singular, labium), which are the "lips" of the vulva. The labia protect the vagina and urethra, both of which have openings in the vulva. Choices: - the cervix - the uterus - the Fallopian tube - the vulva A:
A: the vulva
