To help him study for a quiz on ecosystems, Ali made a table summarizing the features of the ecosystems he needs to know.

Ecosystem Feature
Intertidal zone sometimes covered in water, sometimes not
Neritic zone sunlight passes completely through
Open ocean deepest aquatic organisms are found here
Coral reefs rare for life to be found here
If Ali memorized this table to study for his quiz, which prediction about his test results is most likely correct?

Ali will miss a question on coral reefs.
Ali will miss a question on the intertidal zone.
Ali will get a 100% on his quiz.
Ali will get a 50% on his quiz.

Tara sees a commercial for a brand of pills that promise to boost energy and people perform better in work and school. as people in the commercial talk about how much better they feel when taking the pill, tara notices a message on the bottom of the screen that reads, "this pill is not approved by doctors and has not been tested in controlled experiments." what is the best conclusion that tara should make about the commercial? it is making scientific claims based on subjective observations. it is making scientific claims based on opinions instead of pseudoscientific facts. it is making pseudoscientific claims based on objective observations. it is making pseudoscientific claims based on opinions instead of scientific facts.
