The answer: Ventricles.
There are four ventricles in the brain all connected between them,
where the cerebrospinal fluid is produced. There is a choroid plexus in each ventricle that produce the fluid.
The four ventricles:

- fourth ventricle</span></span>
Answer:
Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and etc...
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Less reproductive isolation among populations that share similar habitats
<h3>What is Reproductive Isolation?</h3>
The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.
They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.
Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids. Temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation are the three modes.
