if a flower were orange would it more likely be pollinated by insects or by the wind give at least one reason for your answer
yan [13]

It would more likely to be pollinated by insects.


This is because the bright color of the petals can attract insects towards the flower thus sticking some pollen grains and transfer them to the stigma (female part of flower).


On the other hand, the color of petals do not really have effect on the wind pollination. Therefore this explains why wind pollinated flowers usually have small or dull colored petals.

A graph titled "Average plant height (cm) vs. Concentration of sodium phosphate (mg/L)" shows an upward-sloping line that reache
vovangra [49]

Answer:

A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Explanation:

The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).

However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.

Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
