A piece of DNA was cut using a restriction enzyme which produced fragments of the following sizes. 350 bp, 1300 bp and 1800 bp.
The fragments were then separated using gel electrophoresis. A molecular weight marker was loaded into lane 1 and the digest fragments were loaded into lane

2. a) The bands for the fragments of the molecular weight marker are shown in lane 1 (fragment sizes are known to be 500 bp, 1000 bp, 1500 bp and 2000 bp). Label the fragment sizes for these bands in base pairs (bp) on the blanks beside the gel.

b) On the gel, sketch the bands that would be produced by the digest fragments.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. threat method number of species that benefit number of years to see benefit habitat fragmentation reforestation 450 8 introduced prey species biological augmentation 150 2 which statement is an accurate explanation of the information in the table? a. biological augmentation would benefit only a few species because it is typically not very effective. b. biological augmentation would take less time to be effective because it targets the majority of prey species. c. reforestation would take the longest time to be effective because trees take several years to grow. d. reforestation would not benefit many species because most forest species live on the ground.
