Numerous degenerative neurological conditions, most notably Parkinson's disease, have been linked to an excessive buildup of alpha synuclein (a-syn) in the brain. Intraneuronal inclusions, often known as Lewy bodies, are neuropathological characteristics seen in Parkinson's disease, Lewy body dementia, and other synucleopathies. The aggregation of a-syn is their main structural component. A-syn accumulation, aggregation, and ensuing Lewy body formation can be attributed to a variety of biological processes. These include genetic changes in parkin, synuclein, or the deubiquitinating enzyme ubiquitin C-terminal hydrolase (UCH-L1), which results in less efficient removal of a-syn via the ubiquitin proteasomal pathway (UPP). Additionally, environmental variables and an age-related decline in antioxidant defense mechanisms that heighten oxidative stress and can have an impact on the formation or clearance of a-syn are intracellular insults.
We focused on changes in the aggregation and clearance of a-syn as impacted by the UPP and the oxidative stress pathways in our dynamic models of a-syn processing in both normal and various disease states. A free radical profile similar to that observed in vivo after exposure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is produced during simulation of enhanced oxidative stress (MPTP). To replicate the kinetics of a-syn that correlates to the neuropathology reported for the sporadic and hereditary types of Parkinson's disease, different model parameters of oxidative stress, UPP failure, or both routes are used. With the use of this in silico model, it is possible to evaluate the kinetics of pathway elements and more accurately identify and validate key pharmaceutical targets.

I’m thinking it’s A as Ice is solid water
Answer:
First, the activity that humans execute that affects their ecosystem positively is reforestation. Second, the activity that humans execute that affects their ecosystem positively is hunting. Their effects rely completely in nature, however, one improves the ecosystem by making it greener and increasing the space nature has to grow, while the other impacts the ecosystem negatively by unbalancing the food chain.
Explanation:
The reasons behind this answer are that in the first place the ecosystem is a very sensitive environment that can be affected by a wide range of factors. In the first place, reforestation helps the environment have better conditions for the animals that live in it, as well as to provide the human race a better quality of air, water and feel better after living in a more natural ecosystem. While hunting breaks the ecosystem's balance because it allows the food chain of the ecosystem to break and allow a general modification.
