Explanation:
The resting membrane potential is negative due to the buildup of more sodium ions outside the cell than potassium inside.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.
Further Explanation:
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient. Parts of a neuron are separated into the
dendrites which receive messages from other neurons allowing them to pass and some of the cell body which contains typical cell components like the nucleus, endoplasmic reticulum and mitochondria.
The axon is an insulated (by the myelin sheath) tubular structure which acts as a bridge to price impulses to other neurons these also contain axon hillocks which are junctions between the axon and cell body
Synapses are junctions where axons connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals.
There are several neuron types which include sensory motor and into neurons which bridge the two.
- The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
- Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential

Answer:
there is a 25% chance that the parents (both Hh) will have a child that does not have the disease
Explanation:
This would be the dichotomous key:
| H | h
H | HH | Hh
h | Hh | hh
Answer:
ATG-TAC-ACC-GGT
Explanation:
T matches with A and C matches with G and vice versa. So the first three TAC would match with ATG.
Answer:
The correct question is;
Sunflower and rice plants are flowering plants. state one similarity and three differences between the two plants.
Answer is: One similarity between the sunflower and rice plant (paddy plant) is that both of them have a non-woody stem. The three differences between them are; sunflower plant is a dicot and has branching veins and taproots while rice plant is a monocot, and has parallel veins and fibrous roots.
Explanation:
The rice plant or paddy plant is a monocot (monocotyledon), where only one embryonic leaf (cotyledon) is present inside the seed coat. The monocots have a fibrous root system and their leaf veins are parallel.
The sunflower plant is a dicot or dicotyledon, which contains two embryonic leaves inside the seed coat. The leaf veins of dicots are branched. They have taproots. Both the sunflower plant and paddy plant can be used as food, and both have a non-woody stem.
