Which of the following is an inference? a burning candle is extinguished when it is covered with a jar. the candle burns longer than expected in a jar that has a plant in it. a plant lives longer than expected in a jar that has a burning candle. there is more oxygen in the jar because there is a plant in it.

The correct answer is option D, There is more oxygen in the jar because there is a plant in it.

Explanation:

An inference is a conclusion derived on the basis of observation from instances. Like in this case the researcher observed that when a candle is burned inside a jar with a plant, the candle burns longer than when it is burned inside a jar without a plant.  From this researcher derived the inference that since plant release oxygen during respiration,  candle was able to burn a little longer .

D: There is more oxygen in the jar because there is a plant in it.

Explanation:

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
