Question

Breeuwer et al. (2008) measured the effect of different temperature regimes on the growth of different Sphagnum species. The g temperatures is shown. Use the information in the graph to answer the following question. 8 a) S. fuscum 3 bc ab Temperature treatment What would you expect to happen to the geographic range of S. fuscum as the temperature of Earth warms? O The geographic range of S. fuscum will not change. O The geographic range of S. fuscum will contract at both the northern and southern ends. 0 The geographic range of S. fuscum will extend southward. O The geographic range of S. fuscum will extend northward.

Explanation / Answer

If the temperature of the earth increases,

the geographic range of S.fuscum will contract at both the northern and southern ends.

As the experiment showed the height of S.fuscum is increasing with increasing temperature. At the northern and southern ends as the temperature is cold, it will reduce the height of S.fuscum.

PART A

control microsomoes did not contain living moss, while experimental microsomes did contain living moss.

PARTB

To control for the possibility that the filtrate contained living moss cells.

Antheridia and archegonia are produced from gametophytes.

The haploid generation grows on sporophyte generation- as gametophytes are haploid. Now, male and female gamets are released from gametophytes. Next, the gamets produced will fuse and make a diploid, which will make sporophytes.
