Which best describes the purpose of a fever? to make the body too hot for the bacteria to live to make the body too cold for the bacteria to live to stimulate lymphocytes to make antibodies to stimulate an increased production of sweat James was exposed to a pathogen when he was 10 years old and felt ill. What would most likely happen if he were exposed to the same pathogen when he is 12 years old? His body would destroy the pathogen before he felt symptoms. His reaction to the pathogen would be worse than the first. His antibodies would decrease, since he had been exposed already. New types of antibodies would be made in response to the second exposure. When studying the immune system in class, Peta concluded that T-cells are more specific to the pathogen than inflammation is. What did Peta most likely learn that led to this conclusion? T-cells are made to identify antibodies, while inflammation starts a fever. T-cells are made to identify antigens, while inflammation starts to make antibodies. T-cells make antibodies that cause a fever, while inflammation identifies antigens on the pathogens. T-cells are made to identify antigens, while inflammation fights anything in the affected area. If an initial population of bacteria doubles every hour, what is the growth factor of this exponential model? This property of water allows for the Water Strider to walk on water. Esta propiedad del agua permite que el Water Strider camine sobre el agua. मानव में उत्सर्जन *7. A bacteria culture doubles every 2 days. After 20 days, it covered the entire surface of the area of the agar on the Petri dish. When did it cover half the area? (2) Part B Which statement explains the effect of temperature on the rate of photosynthesis? (A) Oxygen molecules break down at temperatures above \( 25^{\circ} \mathrm{C} \). (B) The rate of photosynthesis is unaffected by the temperature of the water. (C) The number of chloroplasts in the cell decreases as temperature increases. (D) Enzymies involved with plant photosynthesis are disrupted at temperatures above \( 25^{\circ} \) Describe the vestibular sense The vestibular sense is the sense of balance and spatial orientation. It is responsible for spatial movement and gravitational pull as well as the receptors being the hair cells semicircular canals.
