Answer:
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration!

Answer:</h3>
Cytokinesis in animal cells occur by cleavage while in plants it occurs through the formation of a cell plate.
<h3>
Explanation:</h3>
- Cytokinesis refers to the process through which the cytoplasm divide in animal and plant cells.
- It occurs after the division of the nucleus.
- Cytokinesis in animal cells differs from that in plant cells in that, in animal cells it occurs by cleavage while in plant cells cytokinesis occurs through the formation of a cell plate.
- In animal cells, cleavage occurs as a result of the activity of actin and myosin which results to dividing of cytoplasm in to two.
- In plant cells, cell plate is formed by the fusion of golgi bodies on the equator which will generate cell wall and the plasma membrane between daughter cells.
Sodium reacts with chlorine to form Na+ ions and Cl- ions in spite of the fact that the first ionization energy of sodium is larger than the electron affinity of chlorine. To explain this, we need to divide the reaction between sodium and chlorine
Answer:
As the y-intercept increases, the graph of the line shifts up;
As the y-intercept decreases, the graph of the line shifts down
Explanation:
There are two ways to think about this problem. The first way would be the graphical approach:
- if we only change the y-intercept, this means we keep the same slope;
- y-axis is the vertical axis;
- if we change the point at which the line crosses the y-axis, we either shift it upward for a higher y-intercept or downward for a lower y-intercept.
Now, thinking algebraically, a line has the following equation in a general form:
The y-intercept is essentially obtained when x = 0, then:
y = b:
- if we increase b value, the y value increases, so the graph shifts upward;
- if we decrease b value, the y value decreases, so the graph shifts downward.
