Which of the following factors triggers dormancy in a deciduous tree? a. changes in daylength b. changes in water availability c. changes in temperature d. changes in insect predation

C. changes in temperature

Explanation:

The deciduous trees are the trees that shed their leaves in the autumn, and also minimize their activity during the winter months, starting to be active and grow new leaves in the spring. The main reason for this action by this type of trees is the temperature. The temperature in the winters is very low, often being far beyond the freezing point, making it very difficult for these trees to survive if they are active through it. In order to avoid severe damage or dying out in the winter, these plants hibernate, but also have developed thick bark, and very resilient roots.

answer; ///i believe its(b) they merge because of the strong gravitational pull they exert on each other;

i do agree with robert moses’ statements about wiping out cities that are an “impediment to new growth”. in order to have a positive community, the city must continue to grow either in terms of size or economics. therefore wiping out cities that restrict growth benefits the overall society and all the people living in it. similar to a social contract, i believe that if a person was to live in a community they must sacrifice some of their rights, in this case property, for the overall good of the people. as long as these people living in the cities are reimbursed and the purpose of wiping out the cities is to serve the public, there is no problem with robert moses’ core idea.
