Its true i took a test and got this one right
Answer:ways Water enters the atmosphere evaporation, transpiration, excretion and sublimation:
Explanation:
Transpiration is the loss of water from plants (via their leaves).
Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).
Animals excrete water by respiration and by passing urine.
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
D. Conclusion
After gathering data in support of a hypothesis, you can make a conclusion.
A hypothesis has to be tested multiple times by multiple researchers to become a theory. A fact has to be proven multiple times as well (but theory is a much better word).
Answer:
The inside is becoming positive.
Explanation:
The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.
The depolarization of the cell occur due to the movement of sodium ions inside the cell. The depolarization of the cell changes the membrane potential from -70mV to +30mV. The inside of the cell become more positive than outside of the cell.
Thus, the correct answer is option (a).
