Answer: Option A
Explanation:
Birds attach the bur of the plant which helps in the pollination. The birds sit on the plant and the burs of the plant gets attached in the legs of the birds which is transferred from one place to another.
Seeds at a different place will help in reproduction and growth of the plants. In this case the birds are carrier of the burs.
This is how the birds help in the reproduction of the plants by becoming the messenger.
Answer:
Wildfire
Explanation:
The wildfires are one very devastating occurrence that can appear both naturally and be caused by humans. Naturally these fires occur because of high temperatures and drought, and because of thunders. When they occur, they spread out very quickly and it is an uncontrolled fire. It manages to burn down very large areas of grasslands or forests, moving very quickly and being extremely difficult to put it under control. While the wildfires are very destructive, there's also a positive from them, as they leave behind lot of ashes, and the ashes fertilize the soil, providing the basis for the growth of new vegetation.
<span>Affects of geothermal plants on the environment
</span> Although geothermal plants have many advantages over other conventional fossil fuels units such as it is a renewable resource, but it has many affects as well on the environment.
Forexample
Geothermal plants discharge approximately 6.5 times as much heat, 5.5 times as much water vapours, and 0.5 times as much sulfur per unit of power produces as would a coal plant.
They also release hydrogen sulfide, carbon dioxide, arsenic, and mercury at a concentration that have an adverse but not calamitous effects.
ground subsidence is acknowledged as a potential problem.
pollutant formation may be independent of the power production rate.
Effluent pathways may change abruptly generating hazards that have not been anticipated.
Pre-operational testing and random bore holes contribute negatively to the overall impact.
Waste water may be discharged at temperatures high enough so that utilization of the waste heat becomes both practical and imperative.
Among the given choices, the correct answer is "to maintain normal room temperature". The temperature of the drug is crucial to be maintained at normal room temperature, specifically at around 15 to 30 degrees Celsius; otherwise, in colder temperatures, the drug will crystallize and will be rendered useless.
