ancestors of giraffes with shorter necks could not reach branches high up in trees for food. this led to selection for longer-ne
hichkok12 [17]

With shorter necks, giraffe ancestors could not reach food-containing branches on tall trees. This resulted in the directional selection of giraffes with longer necks.

 

<h3>Why is choosing a direction necessary? </h3>

It nearly appears obvious that the giraffe's long neck developed as a result of a lack of food in the lower branches of trees. The giraffe has a significant advantage because it is taller than any other mammal and can feed where few others can. 

When compared to modern giraffes, the giraffe's ancient predecessors had a shorter neck. The plants that were lying at a higher level were inaccessible to them. Giraffe phenotypes have changed in various ways, and now have long necks to reach vegetation that is higher up. The extreme form is chosen above other features in directional selection. It was decided to choose the long-necked giraffe over the short-necked.

Describe the changes in our lungs when we breathe in and breath out?
Vedmedyk [2.9K]

When you breathe air in your diaphragm tightens and moves downward. It also increases the space in your chest cavity causing your lungs to expand.The muscles in your ribs also help to enlarge your chest cavity. This causes your rib cage to pull upward and outward when you inhale. When you exhale the exact opposite happens.
