It totally depends upon whether modification is being done in somatic cells or germ cells. Somatic cells modification is ethically accepted because it doesn't pass from one generation to another generation but germline modification is considered as unethical because the modification will pass on to the next generation leading to the persistence of modification in future generations. The problem with genetic modifications is that the impacts of modifications are unpredictable, rather than being fruitful they may lead to lethal mutations so if it occurs in just somatic cells, then even if it is lethal/harmful, it will be confined to only that individual but if a lethal mutation occurs in germ cells then it will pass on to the subsequent generations and it will persist in all future generations.
I would go with c because its tells you right in there that the ecosystem help who lives around that area.
Three variables can be used .
1. Sun 2. Moon 3. Earth
These are suggestions that lizzie can control:
1.<span> Discover how long the Earth takes to orbit the Sun
2. how many hours it takes the Earth to spin around once on its own axis, 3. how long the Moon takes to orbit the Earth</span>
Contraction of skeletal muscles against the lymph vessel
The lymph usually move in the body in its own vessel and travels from the interstitial spaces to the subclavian veins at the neck area. The lymphatic system does not have a heart to pump and move the fluid. The movement of lymph depends on the movements of the muscles and joints in the body. In this mechanism upward movement is possible. It will move towards the neck where it will be filtered and will go again into the subclavian veins.
