Question
Use the information to answer the following question. Açai berries come from trees that are native to the Amazon River Basin and now are the basis of many popular fruit drinks. Farmers with small areas harvest the berries in their family farms. Sometimes, they plant additional açai trees, weed out underbrush, and remove other trees in an effort to increase açai production. A recent study compared the forest characteristics of unmanipulated plots versus those where the farmers modified the plants in the plots. This study produced the following results: Acai density (mean # clumps/plot) Number of vines Stem density of all plants Density of non-palm stems Unmanipulated Plots 625 8000plot 4,680/plot 1,400/plot Manipulated Plots 1,000 4,100plot 77.35/plot 4,000/plot Which of the following conclusions are most roasonable to draw from the data presented? Acai production changes the character of the forest when farmers manipulate their plots. Apai production helps alleviate poverty by Amazonian people with small farms. O Açai production will help keep the biodiversity of the Amazonian rainforest intact even when farmers manipulate their plots Acai production does not affect the composition of the forest even when farmers manipulate their plots.Explanation / Answer
Q.1 Ans is A because after manipulating farms the number of non palm trees and vines has increased significantly. even more than density of acai plants. so acai production will change the character of forest when farmers manipulate farms.
Q.2 answer is PARAPHYLETIC. BECAUSE when ancestor with some of its projeny are considered and some are excluded , it is called paraphyletic .all the flowering plants comes under phylum anthophyta but as there are many agencies of pollination and plants have characters according to its pollinating agents so it will be new paraphyletic taxon.
Q.3 ans is 16. because sporophyte means diploid multicellular phase that arise from zygote. when this sporophyte will form gamete it will be haploid having 8 chromosomes so two haploid (egg and sperm) will fuse and make embryo(zygote) that will be diploid and so it will have 16 chromosomes.
