Alocal industrial plant uses oil to run it's furnace and then utilizes the waste heat to convert water to steam to power a turbine. such a use of one fuel to create both heat and electricity is an example of otec cogeneration energy efficiency a fuel cell

The right option is OTEC

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between deep cool ocean water and warm tropical surface waters to produce electricity. Quantities of cold water that can be used for air conditioning is produced as a by-product.

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.
