Technology, since the 19th century, has very much helped the development of Scientific theories. It has helped Scientists use telescopes to look into germs or zoom into the stars, it has also helped Chemists determine the weight of, say, a mashed up apple with soda.
Answer:
Only mutations in reproductive cells can be passed from parents to offspring.
Explanation:
Answer:
The incoming stimuli are converted into the electrochemical signals and are delivered to the central nervous system in form of nerve impulses for perception and interpretation.
Explanation:
The sensory receptors sense the incoming stimuli such as a change in light intensity or temperature. This stimulates the receptors. A sensory receptor converts the energy in the stimulus into a graded potential. This process is called transduction. For example, olfactory receptors of nose transduce the chemical energy of the odorant molecules into electrical energy in the form of a graded potential.
As a graded potential in a sensory neuron reaches a threshold, a nerve impulse is generated and is propagated toward the CNS for integration and perception.
B.
Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
