Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

We can confirm that Ms. Bronner is using a token economy to encourage the rule-following in her classroom.
<h3>What is a token economy?</h3>
This is a method of positive conditioning in which a token of some sort is given as a prize to reinforce positive behavior, with the idea that these tokens may then be exchanged for even greater reinforcers once a certain level is reached.
Therefore, we can confirm that since the methods being described in the questions perfectly correspond to this definition, Ms. Bronner is using a token economy to encourage the rule-following in her classroom.

Answer:
The correct answer is - neurulation
Explanation:
The neural groove is a groove of the neural plate which is a thick plate that is enclosed by the neural folds of an embryo. The neural grove forms the neural tube which expands and develops into the spinal cord and brain.
The development of the neural grove is taken place during the process known as neurulation which is characterized by all characteristic development related to the neural groove and ventricular system.
