Long-term studies of Belding\'s ground squirrels show that immigrants move nearl

Question

Long-term studies of Belding's ground squirrels show that immigrants move nearly 2 kilometers from where they are born and become 1% - 8% of the males and 0.7% - 6% of the females in other populations. On an evolutionary scale, why do you think this immigration is significant? These immigrants provide a source of genetic diversity for the other populations. Gradually, the populations of ground squirrels will move from a clumped to a uniform population pattern of dispersion, resulting in less competition. These immigrants make up for the deaths of individuals, keeping the other populations' size stable. Those individuals that emigrate to these new populations are looking for less crowded conditions with more resources. The goal of restoration ecology is to __. manage competition between species in human-altered ecosystems replace a ruined ecosystem with a more suitable ecosystem for that area prevent further degradation by protecting an area with park status return degraded ecosystems to a more natural state Which of the following is a unique trait of fungi? heterokaryotic stage of the life cycle haploid stage of the life cycle is dominant absorption of nutrients from the environment cell walls made of chitin more than one of these traits is unique to fungi

Explanation / Answer

Question 63

Cell wall made up of chitin is not unique to fungi but is also found in arthropods and insects.
Absorption of nutrients from the environment, i.e. saprophytic nature is not unique to fungi but is also found in plants and micro-organisms that feed on dead and decayed matter.
Dominant Haploid stage of life cycle is unique to fungi.
Heterokaryon are unique to fungi and hence the option that more than one of these traits is unique to fungi is the correct option.
