What are three ways the rate of a chemical reaction can be changed

The temperature - warmer debris circulate swifter and collide greater oftentimes with greater ability.

2. The rigidity - debris in gases squeezed at the same time will collide greater oftentimes.

3. concentration of any reactants in answer.

4. floor section of any good reactants (powders have a larger entire floor section)

5. The presence of a catalyst. (catalysts decrease the activation ability)

Explanation:

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.

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.
