Aland developer and several ecologists are discussing how a parcel of private land should be developed while saving 20 hectares as natural habitat. the land developer suggests that the 20 hectares be divided into twenty separate 1-hectare areas. the ecologists suggest that it would be better to have one intact parcel of 20 hectares. what is the significance of these different arrangements of the 20 hectaresa. the isolated hectare piots increase the ability of individuals to disperse from one habitat to another. b. the large plot will create more inbreeding in many species c. there really is no difference: they should both work equally well. d. the isolated plots are more vulnerable to edge effects.

The correct answer is option D.

Explanation:

Land developers and ecologists are providing different suggestions for saving the land of 20 hectares of natural habitat. Both have a different approach for developing the land, the land developer suggests to divide the land to 20 one hectare areas. While the ecologist suggests that it would be better to have one intact land. The land with isolated areas is more vulnerable to edge effects.

Edge effects are the modification or change in the structure of the community that presents at the edge of the two or more than two habitats. Areas with small habitat fragments show high edge effects.

Thus, the correct answer is option D.

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
