Which temperature is colder, -187°c or -168°c?

The customary unit for measuring temperature is degrees Fahrenheit (°F). The metric unit for measuring temperature is degrees Celsius (°C). Water freezes at 0°C. Water boils at 100°C. Room temperature is about 20°C. The greater the temperature, the warmer it is.

Explanation:

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
