Question

true or false 5 points natural selection can only act on traits that are heritable. true or false 10 points evolution by natural selection leads to perfectly adapted organisms. true false multiple choice 5 points which of the following environments would you most likely find thermophiles? salt flats bottom of ocean hot springs polar ice caps

Explanation:

• Question 7: Natural selection acts on heritable traits. This is a fundamental principle in biology. Traits that are not heritable cannot be passed on to offspring and thus cannot be influenced by natural selection.
• Question 8: Evolution by natural selection does not lead to perfectly adapted organisms. There are several reasons for this, such as genetic drift, gene flow, and the fact that the environment is constantly changing. Organisms are always in a state of "good enough" adaptation rather than perfect adaptation.
• Question 9: Thermophiles are heat - loving organisms. Hot springs are environments with high temperatures, which is the kind of environment where thermophiles are likely to be found. Polar ice caps are cold, the bottom of the ocean can have a wide range of conditions but is not typically associated with high - temperature thermophiles, and salt flats are more related to high - salt conditions rather than high - temperature conditions for thermophiles.

Answer:

• Question 7: True
• Question 8: False
• Question 9: Hot springs
