Which of the following statements is correct regarding the evolution of flight?
xxTIMURxx [149]

Answer:

d.The wing-assisted incline running theory postulates that wings were initially used to maintain balance while climbing up slopes.

Explanation:

Two theories were given to explain the origin of avian flight. The top-down theory suggested that the birds' ancestors were tree dwelling species. They took help of wings to glide from tree to tree in order to avoid predator or catch prey. The bottom up theory suggested that the birds' ancestors were ground dwelling species. They took help of wings to maintain a balance and provide a lift for efficient running.

Wing-assisted incline running was a mixture of both the above theories and gave a balanced view point. According to it, birds' ancestors used wings to maintain a balance while running up inclined slopes. The wings helped them to save energy while scaling slopes and eventually a flight mechanism was also developed.

According to Piaget's theory of cognitive development, which of the following is true of children in the concrete operational st
Anika [276]

Answer:

A. They center on the motives of wrongdoers as well as on the amount of damage done when assigning blame.

Explanation:

The Concrete Operational Stage, according to Piaget, refers to a stage that begins around age 7 and ends around the ages of 11 or 13.

During this stage, children are now capable of thinking in a more logical manner and their moral judgement has become subjective as <u>they now center on the motives of wrongdoers as well as on the amount of damage done when assigning blame</u>. For instance, they are able to judge another child according to the amount of damage she/he has done and whether it was done in purpose or accidentally.

They can also center on two dimensions of a problem at once and have thoughts that involve tangible objects instead of abstract ideas.
