Verdich [7]

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.

Larger the size of an organism bigger the size of its cells. Do you agree with this statement? Give scientific reasons.
vodomira [7]

Answer:

Disagree.

Explanation:

Though some cells are bigger than others, they do not scale with size. For example if you look at skin cells on a dog they would be similar in size to a skin cell from a human. When an animal or species is bigger it is usually just made from more cells.
