Can someone help me with an intro to a research paper about the petronas towers

Establish which of the following statements are true. (a) a sequence is convergent if and only if all of its subsequences are convergent. (b) a sequence is bounded if and only if all of its subsequences are bounded. (c) a sequence is monotonic if and only if all of its subsequences are monotonic.

Which statement best explains how plant cells use photosynthesis to maintain homeostasis? they use glucose and water to make energy. they break down glucose into fat. they combine oxygen and water to make glucose. they make glucose from carbon dioxide and water.

Im doing this last minute and literally none of my neighbors or people that my dad works with use excel so if anyone could me make up an example
