Answer:
Avery expanded on Griffith's observations by demonstrating that it is the DNA, and not the proteins, that is responsible for the genetic information.

Answer:
d. 40, B.4 unique
Explanation:
If 10 cells underwent meiosis, the result would be 40 daughter cells. This is because a cell that goes through meiosis goes through two divisions resulting in 4 daughter cells. This is because cells that undergo meiosis are gametes so they need to have half the number of chromosomes as the cells that go through mitosis.
The resulting daughter cells are unique, unlike the cells that go through mitosis. This is because the chromosomes in the cells experience something called crossing over during Metaphase I. Crossing over is when the chromosomes can swap pieces of DNA when next to each other. Cells in mitosis don't go through crossing over and are therefore identical.
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.
