Answer:
Air-sea exchange is a physio-chemical process and is important for the cycling of gases such as carbon dioxide, methane, nitrous oxide, dimethylsulfide and ammonia
Answer:
b is the correct answer ok bro
If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
Answer:
In a particular case of secondary succession, three species of wild grass all invaded a field. By the second season, a single species dominated the field and the other two species had a lower relative abundance. A possible factor contributing to the abundances of these species in this example of secondary succession is <u>inhibition</u>.
Explanation:
Trees are great examples of allelopathy in plants. Some use their allelochemicals to inhibit germination or impede development of nearby plant life. Most allelopathic trees release these chemicals through their leaves, which are toxic once absorbed by other plants. Black walnut is a prime example of this.
<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.
Explanation:
Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.
Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.
