1. Lake Hawassa is one of the major freshwater bodies in Ethiopian country. It supports a lot of organisms ranging from the microalgae (phytoplankton) to different fish species.
Phytoplankton is the primary producer; zooplankton and omnivores fish feed on, zooplankton, in turn, serves as food for carnivorous fishes at the trophic level. If Nile perch (piscivorous fish ) from Lakes Chamo and Abaya introduced to lake Hawassa, What will happen to the trophic status of the lake? (4pt)

Q1-Gene therapy research aims to use genetic material (DNA or RNA) to develop
effective new treatments for a range of serious genetic conditions.
(a)
Critically discuss the strategy you would use to develop a gene therapy
treatment for a named monogenic disorder. Your answer should include
details of the therapeutic genetic material, how you would deliver this to
the affected cells, and the reasons for your choice.
(b)
Evaluate the regulatory challenges and potential safety issues that would
need to be overcome before your new gene therapy treatment could be
used to treat patients.
