Answer:
The movement of potassium ions out of the axon.
Explanation:
The membrane potential or cell potential is the difference in the electric potential outside and inside of the cell. The cell potential is important for the transmission of nerve impulse.
The resting potential of the cells is -70mV. The movement of sodium ions causes the cell depolarization and makes the membrane potential more positive. The cells sometimes attain the more negative membrane potential stage known as hyperpolarization. This state mainly occur by the efflux or the movement of the potassium ions out of the axon.
Thus, the correct answer is option (A).
Temperature and precipitation.
Answer:
Unicellular
Explanation:
Protists can be defined as a group of eukaryotes that can not be regarded as fungi, animals or plants. These type of organisms are known to be very diverse. They are mainly microscopic in nature and are also known to possess a single cell. That is they are unicellular.
This unicellular attribute is the primary or main differentiating feature between protists and other eukarya.
The f1 progeny all are checkered It is an example of codominance.
In genetics, codominance refers to a kind of inheritance inside which two variants (alleles) with same gene are activated separately to produce distinct features in a person. Codominance may be seen in spotted cows and plants with petals of two distinct hues.
Codominance can also be seen in less obvious features such as type of blood. Both the A and B blood type alleles can be produced simultaneously at the same time, producing in type AB blood. Codominance, as distinguished to partial domination, occurs when both parents' traits are manifested in the same child organism.
Codominance is a widespread phenomena that is likely to be a major driver of community composition, ecosystem function, and both community and ecosystem stability. While researching polygenetic features and their inheritance, Gregor Mendel identified the phenomena of codominance.
