A land developer and several ecologists are discussing how a parcel of private land should be developed with housing while saving 20 hectares as natural habitat. The land developer suggests that the 20 hectares be divided into 20 separate 1-hectare areas, spread out across the area. The ecologists suggest that it would be better to have one intact parcel of 20 hectares on one side of the larger area. What is the significance of these different arrangements of the 20 hectares?

#Unit 9. Diversity of Life Forms
  1. The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

  2. The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

  3. The separate 1-hectare plots are less vulnerable to edge effects.
  4. The large plot will create more inbreeding in many species.

Following statements are regarding to the regulation of body temperature.
A. The temperature-regulating center is located in the anterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the skin and about core temperature from thermoreceptors in the anterior hypothalamus itself.
B. The temperature-regulating center is located in the posterior hypothalamus. This center receives information about environmental temperature from thermoreceptors in the posterior hypothalamus itself and about core temperature from thermoreceptors in the skin.
C. If core temperature is below the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
D. If core temperature is above the set-point temperature, then heat-dissipating mechanisms are activated.
E. If core temperature is below the set-point temperature, then heat-dissipating mechanisms are activated.
F. If core temperature is above the set-point temperature, then heat-generating and heat-retaining mechanisms are activated.
