This lesson discussed the engineering design process and the devastation of three ecosystems: the Kitakami River region, the Abukuma Highlands, and Japan's coastal habitat. In this activity, you will select one of these ecosystems and follow the steps of the engineering design process to design a recovery solution. Complete each section of the Recovering Ecosystems Worksheet, including the problem, sub-problems, criteria and constraints, and proposed solutions for ecosystem recovery. Instructions for each section are included in the worksheet. Be sure to review the assignment's rubric before completing and submitting this assignment.

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.  

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
