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.

Answer: A specific chemical binding to nociceptors
Explanation:
Answer: D. Plants do not eat, so both chloroplasts and mitochondria are needed to make enough energy for plants to grow.
Explanation: Option A is invalid since plant cells do use ATP. Option B is invalid since animal cells don't make their energy with chloroplasts. Option D is the most realistic one since chloroplasts in the plant are the ones that make the food for the plants, plant doesn't have a "mouth" so they depend on chloroplast to make food.
