Answer:
Potassium
Explanation:
Resting membrane potential may be defines as the voltage or charge difference between inside and outside of the cell when the cell is at rest. The resting membrane potential of the cell is -70mV.
Potassium ion channels are leaky channels that are always open and can move into and out of the cell. The potassium ions are responsible for setting of the resting membrane potential of the cell. Inward movement of sodium ions may disrupt the resting membrane potential of the cell.
Thus, the correct answer is option (B).
The number of available electrons. bonds to other atoms occur when both of the atoms in the compound or miles have available electrons to connect to other atoms
Answer:
Homeostasis
Explanation:
Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.
An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.
Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.
Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
Answer:
The correct option is B. A hypothesis
Explanation:
Scientific method can be described as a method following which all scientific researches are made. The scientific method begins with a question. To answer this question, a hypothesis is derived.
A hypothesis can be described as a statement based on which observations are made end experiments are done. A hypothesis is a tentative statement. As the student in the question writes a tentative statement in his/her journal, hence it is most likely to be a hypothesis.
