Answer:
Explanation:
Dilute solutions are prepared so as to allow a significant amount of light to pass through the solution and be measured by the recorder. Opaque solution are also diluted so light can pass through and be recorded. Similarly other substances which have very large absorption have to be diluted so that significant amount of light could reach detector.
Answer:
Colliding?
what are the answer choices firstly.
Explanation:
Answer;
-Dendrites receive chemical signals.
-When more excitatory than inhibitory signals are received, the cell depolarizes.
-An action potential is set off and travels through the cell and down the axon.
-The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.
Explanation;
-The electrical signal that passes along the axon and subsequently causes the release of chemicals from the terminal buttons
. Chemical signals (excitatory and inhibitory signals.
-Positive sodium pours into the breach, Action potential propagates along the axon, after firing returns to its slightly negative resting state.
-An action potential can be generated if the amount of excitatory input can raise the membrane potential to -55 mV. This then floods the cell with sodium ions and raises the membrane potential. When it reaches a certain point (about +30 mV), the sodium ion channels close and the potassium ion channels open. This drops the membrane potential back down.
Answer:
conjugation
Explanation:
Bacteria reproduce by binary fission, resulting in two daughter cells identical to the parent cell. Bacteria can exchange DNA through the processes of conjugation, transformation, or transduction.
Answer:
The DNA sequence that can be directly compared between the two genomes is almost 99 percent identical. When DNA insertions and deletions are taken into account, humans and chimps still share 96 percent of their sequence. At the protein level, 29 percent of genes code for the same amino sequences in chimps and humans.
