Which of the following statements is true? 1. the mantle of the earth is made of solid nickel and iron. 2. the crust of the earth is made of solid nickel and iron. 3. the inner core is made of solid nickel and iron.

3. The inner core is made of solid nickel and iron.

Explanation:

This is the statement that best reflects the reality of the Earth's composition. The inner core of the Earth is made of solid nickel and iron. Moreover, this is the hottest part of the planet. In fact, it is considered to be about the same temperature as the surface of the Sun. We owe the discovery of the inner core to Danish seismologist Inge Lehmann.

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.  

yes it is weird but true
