Answer:
The emergence of the new species of the organisms may take place if the naturally occurring selective pressure encourages the emergence of new traits. The pressure from the surroundings like sudden variation in the climate or temperature or any other thing that develops a pressure on the species to modify phenotypically and genotypically.
This change will result in the evolution of the species and with the time being the emergence of new species of organisms takes place.
naturally occurring selective pressures favor new traits.
humans create new environmental conditions.
B) savanna
C) taiga
D) tundra
Answer:
[B]
Explanation:
The savanna biome makes up half of the surface of Africa. The biome is mabe up of mostly grasses and few scatted trees. Since the desert has nlittle to no grass and the taiga biome is the smallest in Africa and has little grass, while tundra biome is also small to non-existent in Africa. The perfect answer is B for savanna biome.
B. 1.001-1.035
C. 1.030-1.040
D. 1.000-1.015
B. Opening windows
C. Installing HEPA filters
D. Increasing the house temperature
Answer:
D. Increasing the house temperature
Explanation:
Increased level of temperature and humidity support the growth of microbes in the house and thereby pollute the indoor air. Indoor plants remove carbon dioxide and help in reducing indoor pollution. Likewise, entry of fresh air into the house by opening windows and use of HEPA filters also make the air of house free of pollutants.
Answer:
The correct answer is option D. "Increasing the house temperature".
Explanation:
Reducing indoor pollution is achieved by a series of practices that help to improve the quality of air within a closed environment. Among the different practices herein proposed, increasing the house temperature is the one that is lest helpful to reduce indoor pollution. In fact, some scientific studies suggest that increasing the house temperature is related to an increase in indoor pollution by the use of heating devices and exposure to the contaminants that they generate.
