Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The phrase describes kangaroos' geographic distribution using passive voice structure. 'Found only in Australia' correctly indicates where kangaroos exist. 'Born only in Australia' is incorrect (they're born everywhere they live), 'left only' implies abandonment, and 'taken only' doesn't convey natural habitat.

A Correct answer
Explanation

The sentence describes simultaneous action: kangaroos balance their bodies at the same time as hopping. 'While' correctly expresses two concurrent actions. 'When' could work but 'while' is better for emphasizing duration. 'Through' implies movement across something, and 'by' would require 'hopping' as a gerund ('by hopping').

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A circadian rhythm is any biological process that displays an endogenous oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi and cyanobacteria. The term circadian comes from the Latin circa, meaning around and diem or dies, meaning day. The rhythm is linked to the light–dark cycle that is photoperiod. Circannual rhythm in an animal is an adaptive character developed by the animals in response to the frequent changes in the environment.
