The sudden removal of tall trees could lead to the extinction of an eagle species that relies on such trees for nesting. Rapid development of new traits or mutations is biologically unlikely. This situation emphasizes the importance of maintaining natural habitats for biodiversity.
The sudden removal of tall trees in a forest area can indeed lead to drastic changes in the local ecosystem. Among these potential outcomes, the one most likely to occur is that the species of eagle that nests in tall trees could become extinct.
This is because the eagles are specifically adapted to nest in tall trees, and such traits have been developed over a long evolutionary process. Therefore, a quick adoption of a new trait or creating a random mutation is biologically unlikely without a substantial period. Changing its nesting behavior could be possible, but again this would require time and pressure from the environment.
Overall, this issue highlights the importance of preserving natural habitats to maintain biodiversity.

Echinoderms, like sea stars, have a nervous system like nerve net. The correct answer is option C.
The nervous system is a complex network of specialized cells called neurons that transmit signals between different parts of the body. It is responsible for coordinating and controlling all of the body's functions, including movement, sensation, thought, and emotion.
Therefore, the correct answer is option C. Nerve net.

Salvatore's decision to dump his fish tank and its contents into a nearby freshwater canal could have devastating consequences for the ecosystem.
The non-native fish species from the tank could outcompete and prey on native fish, leading to disruptions in the natural balance and potentially causing local extinctions.
The uneaten fish food and waste from the tank could lead to water pollution, harmful algal blooms, and a decline in water quality, affecting aquatic plants and other animals in the canal.
This irresponsible action could harm the delicate biodiversity of the canal, disrupting the entire ecosystem and leading to long-term environmental damage.
