Answer:
Ecological Succession is the process by which the structure of a biological community changes over time. The Natural selection process is the selection process of its selection work. They are both similar because they are unsuitables gradually that disappear from the population. Its important to have both because they both provide growth and development of the ecosystem.
Explanation:
Answer:
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.

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.
As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply.
