Answer the following question given this paragraph: Conduct experiments or make observations to test the hypothesis. Q: How do you test a hypothesis? Choices: - write things on paper - ask a co-worker about it - think of how they would work - conduct experiments A:
conduct experiments
Answer the following question given this paragraph: The basic building blocks of the human body are cells. Human cells are organized into tissues, tissues are organized into organs, and organs are organized into organ systems. Q: What are the basic building blocks of the human body? Choices: - proteins - minerals - vitamins - cells A:
cells
Q: Answer the following question given this paragraph: Sensory systems deformed by gelatinous membrane. Vestibular apparatus, gives us perception of gravity and movement. Due to physical response, not chemical binding. Cochlea: bony, coil shaped part of inner ear, where hearing occurs. Sound enters through auditory canal, vibrates tympanic membrane,moving three bones of middle ear (malleus, incus, and stapes)against oval window opening in front of cochlea. Cochlea has three fluid filled ducts, one of these the organ of Corti. Sound waves in air go to vibration in organ of Corti; fluid tickles hair cells, which register the movement along basilar membrane in cochlea. Different sound frequencies move different portions of basilar membrane. Hearing loss due to loss of hair cells. Humans normally smell more than 300 odors in a day(Facts and Truth). Transduction of sound accomplished throgh physical deformation,not chemical binding. Q: What ear structure has three fluid filled ducts, including the organ of corti, where sound waves in air go to vibration? Choices: - semicirciular canal - saccule - utricle - cochlea A:
A: cochlea
Question: Answer the following question given this paragraph: Unlike that of the Hexapoda, the head and thorax of most crustaceans is fused to form a cephalothorax (Figure 28.40), which is covered by a plate called the carapace, thus producing a body structure of two tagma. Crustaceans have a chitinous exoskeleton that is shed by molting whenever the animal increases in size. The exoskeletons of many species are also infused with calcium carbonate, which makes them even stronger than in other arthropods. Crustaceans have an open circulatory system where blood is pumped into the hemocoel by the dorsally located heart. Hemocyanin and hemoglobin are the respiratory pigments present in these animals. Q: In most crustaceans, what two structures fuse to form a cephalothorax? Choices: - foot and toes - body and shoulders - wing and legs - head and thorax A:
Answer: head and thorax

Answer the following question given this paragraph: Root Growth and Anatomy Root growth begins with seed germination. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. The root cap is continuously replaced because it gets damaged easily as the root pushes through soil. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 30.16). The zone of cell division is closest to the root tip; it is made up of the actively dividing cells of the root meristem. The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types. All three zones are in the first centimeter or so of the root tip. Q: Why is the root cap continuously replaced in plants? Choices: - due to growth - due to pressure - due to rubbing - damage through pushing A:
**Answer**
damage through pushing

Answer the following question given this paragraph: Figure 46.14 Water from the land and oceans enters the atmosphere by evaporation or sublimation, where it condenses into clouds and falls as rain or snow. Precipitated water may enter freshwater bodies or infiltrate the soil. The cycle is complete when surface or groundwater reenters the ocean. (credit: modification of work by John M. Evans and Howard Perlman, USGS). Q: Water from the land and oceans enters the atmosphere by which process? Choices: - absorption - condensation - transpiration - evaporation A:
(Answer)
evaporation
