Answer:

Change in food source.

Explanation:

If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.

Ganezh [65]
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.

The exchange of wastes through the skin is just called excretion by sweating. 

There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.

The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.

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.
