Answer:
Long beaks of medium ground finches allows them to opt for alternate sources of food in times of extremities while this is not the case with the cactus finches.
Explanation:
The medium ground finches have larger beaks and thus apart from small seeds they can also break open the large seed. In case if the small seeds get scarce, a medium ground finch can still survive by taking advantage of feeding on alternate source of food but small beaked birds such as cactus finches shall die out of starvation.
This adaptation of medium ground finches gives it a survival advantage over the cactus finches
Answer:
<em>The correct option is A) increase in atmospheric O2</em>
Explanation:
The nerve cells and the muscle cells suggest that the the presence of oxygen in the atmosphere was an adaptive radiation which brought the existence of different animals. The conditions became favorable for different animals to survive on Earth only when the availability of oxygen improved in the atmosphere. As animal cells like the muscle cells require a constant supply of oxygen, we can hence say that increase in atmospheric oxygen was the adaptive radiation for supporting many group of animals.
Mammals are unique in possessing a diaphragm to pull O2 into the lungs. The voice box is the larynx. Both the digestive and respiratory tracts are shared by the pharynx. Pseudostratified ciliated columnar is the epithelial tissue that is destroyed by smoking but can regenerate if smoking stops. The role of surfactant is to reduce surface tension. The primary role of hemoglobin is to carry oxygen. The inflammation of bronchi is called bronchitis.
