Answer the following question given this paragraph: Before lymph reaches the bloodstream, it passes through small oval structures called lymph nodes, which are located along the lymph vessels. Figure below shows where some of the body's many lymph nodes are concentrated. Lymph nodes act like filters and remove pathogens from lymph. Q: What act like filters and remove pathogens from lymph? Choices: - spine nodes - tissue nodes - electric nodes - lymph nodes A:
lymph nodes
Answer the following question given this paragraph: Fossils are preserved remains or traces of organisms that lived in the past. Most fossils form in sedimentary rock. Fossils can also be preserved in other ways. Fossilization is rare. It's very unlikely for any given organism to become a fossil. Q: What is the term for preserved remains or traces of organisms that lived in the past? Choices: - deposits - bones - remains - fossils A:
fossils
Q: Answer the following question given this paragraph: Mesophiles grow best in moderate temperature, typically between 25C and 40C (77F and 104F). Mesophiles are often found living in or on the bodies of humans or other animals. The optimal growth temperature of many pathogenic mesophiles is 37C (98F), the normal human body temperature. Mesophilic organisms have important uses in food preparation, including cheese, yogurt, beer and wine. Q: What type of organism is commonly used in preparation of foods such as cheese and yogurt? Choices: - protozoa - gymnosperms - viruses - mesophilic organisms A:
A: mesophilic organisms
Question: Answer the following question given this paragraph: The amount of energy in molecules of matter determines the state of matter . Matter can exist in one of several different states, including a gas, liquid, or solid state. These different states of matter have different properties, which are illustrated in Figure below . Gasses have the most energy, and solids have the least energy. Q: What is determined by the amount of energy in molecules? Choices: - kingdom - radioactivity - momentum - state of matter A:
Answer: state of matter
*Question*
Answer the following question given this paragraph: Human cells normally have two sets of chromosomes, one set inherited from each parent. There are 23 chromosomes in each set, for a total of 46 chromosomes per cell. Each chromosome in one set is matched by a chromosome of the same type in the other set, so there are actually 23 pairs of chromosomes per cell. Each pair consists of chromosomes of the same size and shape that also contain the same genes. The chromosomes in a pair are known as homologous chromosomes . Q: How many chromosomes are in each set? Choices: - 22 - 21 - 13 - 23 A:
**Answer**
23
Q: Answer the following question given this paragraph: The inner ear is often described as a bony labyrinth, as it is composed of a series of canals embedded within the temporal bone. It has two separate regions, the cochlea and the vestibule, which are responsible for hearing and balance, respectively. The neural signals from these two regions are relayed to the brain stem through separate fiber bundles. However, these two distinct bundles travel together from the inner ear to the brain stem as the vestibulocochlear nerve. Sound is transduced into neural signals within the cochlear region of the inner ear, which contains the sensory neurons of the spiral ganglia. These ganglia are located within the spiral-shaped cochlea of the inner ear. The cochlea is attached to the stapes through the oval window. The oval window is located at the beginning of a fluid-filled tube within the cochlea called the scala vestibuli. The scala vestibuli extends from the oval window, travelling above the cochlear duct, which is the central cavity of the cochlea that contains the sound-transducing neurons. At the uppermost tip of the cochlea, the scala vestibuli curves over the top of the cochlear duct. The fluid-filled tube, now called the scala tympani, returns to the base of the cochlea, this time travelling under the cochlear duct. The scala tympani ends at the round window, which is covered by a membrane that contains the fluid within the scala. As vibrations of the ossicles travel through the oval window, the fluid of the scala vestibuli and scala tympani moves in a wave-like motion. The frequency of the fluid waves match the frequencies of the sound waves (Figure 14.6). The membrane covering the round window will bulge out or pucker in with the movement of the fluid within the scala tympani. Q: What part of the ear is often described as a bony labyrinth? Choices: - embedded ear - solid ear - outer ear - inner ear A:
A: inner ear
