Answer:
She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)
Explanation:
This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.
Answer:
1. B. Medulla oblongata contains cardiac, respiratory, vasomotor and reflex centers.
2. A. Hypothalamus is the major regulator of ANS
3. D. Occipital lobe is the location of visual cortex.
4. F. Sensory areas are primary site responsible for perceiving cutaneous sensory sensations and proprioception.
5. E.Motor areas directs conscious motor movement
6. C. Cerebellum - coordinates movement by comparing intended movement with actual movement.
7. K. Corpus callosum allows communication between right & left cerebral hemispheres.
8. J. Frontal Lobe - Cognition, personality.
9. A. Hypothalamus - Contains hunger, thirst and thermoregulatory centers.
- The illustration is a representation of the different ways molecules are transported across a cell membrane, that represents active transport is IV.
- Active Transport is described as a process that involves the movement of molecules against a gradient or an obstruction from a location of lower concentration to a region of greater concentration.
- A protein pump uses ATP, which is a form of stored energy, to move molecules during active transport.The process of active transport, which moves molecules using ATP as an external energy source.
- Some examples of active transport include the absorption of glucose in the human intestine and the uptake of minerals or ions into the root hair cells of plants.
- Active transportation comes in two flavors:
- Primary active transport
- Secondary active transport.
