Answer:
Thermophiles have heat-resistant enzymes.
Explanation:
A hypothesis refers to the possible explanation of processes and is based on observation.
Thermophiles are able to survive the extremes of the temperature found in hot springs of Yellowstone National Park. Their ability to withstand such temperature may be due to the presence of heat resistant enzymes.
Since enzymes are proteins, they are denatured at higher temperatures. It is one of the factors that determine the temperature range that can be tolerated by an organism.
Hence, the presence of heat resistant enzymes in thermophiles can be one of the possible explanations about their ability to survive under the temperature as high as 205 degrees Fahrenheit.
Explanation:
Answer : The process of transpiration can be demonstrated by tying a polythene bag around the rose plant and keeping the plant in sunlight for one or two hours. Droplets of water would be seen on the inner sides of polythene bag due to transpiration.

Explanation:
The causes of monocultures are the economics of
global product of agriculture, standard of industrial society, and the apparent
“simplicity” of managing only one crop.
The major cause of the loss of top soil is
soil erosion (which is caused by the factors like water, wind and tillage of
farm fields). Loss of top soil become a global problem for agriculture.
<span>A species that are occurring outside of its
normal distribution are known as Alien species. The cause of alien species is
that these species are not native to ecosystem and they can cause harm to the
environment.</span>
