<span>Penile shaft
</span>During erection, blood<span> flows into the spaces, causing distention and elevation of the penis. The amount of blood entering the penis can be increased by physical or psychological stimulation. As blood enters, there is a temporary reduction in the rate and volume of blood leaving the penis. The arteries carrying blood to the penis dilate; this, in turn, causes tissue expansion. The veins leading from the penis have funnel-shaped valves that reduce the outflow of blood. As the erectile tissue begins to enlarge, the additional pressure causes the veins to be squeezed against the surrounding fibrous tissue, and this further diminishes the outflow of blood. Essentially, blood becomes temporarily trapped in the organ.</span>
Answer:
B. Position B
Explanation:
The values for dependent variable are plotted on the y-axis (vertical) on a scatter plot. Therefore, the label for the dependent variable would be written along the vertical axis for the scatter plot, at position B.
The label for independent variable would be written along the horizontal axis for the scatter plot, at position C.
The answer is "B. Position B"

Answer:
<em>Hypotheses may vary. Most students will probably state that ecosystems at
</em>
<em>high altitudes will support little vegetation. </em>
Explanation:
Ecosystem distribution is different at different places. Regions at high elevations might usually have low varieties of plants and animals but it cannot be true for every ecosystem located as higher altitudes.
Some communities might be well adapted to live in the cold and hence progress rapidly.
Answer:
Higher objects (with further to fall) have greater potential energy. therefore the maximum height would have the highest amount of potential energy
