- Question 16 (1 point) Below are the word equations for two important biochemical reactions. Photosynthesis: carbon dicxide+water+energy-sugar+oxygen Cellular Respiration: sugar+oxygen-carbondioxide+water+energy What can you conclude from these word equations? Photosynthesis is an endothermic reaction and cellular respiration is an exothermic reaction Photosynthesis is an exothermic reaction, and cellular respiration is an endothermic reaction Both photosynthesis and cellular respiration are exothermic reactions Both photosynthesis and celiular respiration are endothermic reactions
- 4 Multiple Choice 1 point Which of the following statements CORRECTLY describes the function of a component of a reflex arc? Sensory neurons gather information from effectors Motor neurons conduct impulses from interneurons to effectors Sensory receptors receive stimuli from interneurons Effectors act as integration centres Clear my selection
- 2. What is the term for errors that occur with a specimen before it is tested? (A) Pretest problems (B) Collection mistakes (C)Venipuncture errors (D)Preanalytical errors
- 1 The threshold potential of most neurons is a depolarization to about -55mV or more. A depolarization to less than -55mV has no effect on the creation of an action potential less effect than a depolarization to the threshold more effect on the creation of an action potential the same effect as a depolarization to the threshold Clear my selection Multiple Choice 1 point
- 4x Drag and drop each term or phrase to correctly complete the prompt. Carbon is the basis for life on Earth.Plants use water, square ; from the air, and energy from sunlight to make food. This process is called photosynthesis square eat square breathe in oxygen and breathe out carbon dioxide. This is called respiration Carbon is released into the atmosphere when plants and animals die and decompose Carbon dioxide is also released into the air through combustion : plants : Animals : carbon dioxide
