Based on the broth left on an open flask experiment, wherein the boiled broth was placed in two flasks (one flask with straight neck and the other flask has a bent neck) and exposed to open air at room temperature for several weeks.
The broth within the straight neck flask has changed its appearance. It became discolored and cloudy. Whereas, the broth in the bent neck open flask still remains the same.
These results would then support the conclusion that germs in the air were able to fall unobstructed towards the straight neck flask and contaminate its contents. While, the bent neck of the 2nd open flask acted as a trap for the germs, preventing the germs from contaminating the broth. Further emphasizing that germs can only come from other germs and not from spontaneous generation.

providing the body long distance coordination with the use of homeostasis and
their role of maintaining it, in order to play their roles in the body.

Answer:
Large number of species and abundant resources.
Explanation:
Large number of species and abundant resources are the two characteristics shared by ecosystems that have high biodiversity. Habitat loss and pollution are the two specific human activities that result in a loss of biodiversity. Habitat loss occur when the human removed all the trees and vegetation in order to made the land for cultivation of crops or building houses. Pollution is the main cause that leads to loss of biodiversity. Human activities release gases which pollute the environment and leads to loss of biodiversity. Avoid activities that causes pollution and used of barren lands for cultivation and infrastructure. Climate change is naturally occurring factor that could lead to a loss of biodiversity. Biodiversity boosts ecosystem productivity and natural sustainability.
B) sunlight
Sunlight supports life by providing food and warmth which is needed for the population of practically anything on earth to survive
