Answer:
Rock
Explanation:
Minerals are inorganic substances that occur naturally in nature and have a
a definite chemical composition and a crystalline structure while rocks may consists of one or many minerals together along with some organic remains due to which it may not look shiny and crystalline from outside.
Here, the two characteristics that enable the reader to identify the object given by grandmother to Emily as rock are –
a) Looks ugly on the outside (shows the presence of organic matter)
b) solid purple color with pretty crystals (crystalline structure inside)
Heat and light (campfire), chemical ( beans as food), and kinetic (you hiking).

we have been evolved through same root, during the process we get separated and develop new features to adjust in the surrounding atmosphere, that's why our genes are matching with fruit flies and others.
<span>One important area of DNA research is that of genetics and medical research. Due to our discovery of DNA, our ability to actually diagnose diseases early on has been vastly improved. In addition, we have been able to better assess a person's genetic susceptibility to specific diseases. In doing so, we have also paved the pathway to formulate brand new drugs to treat these diseases. In fact, drugs can essentially be custom made to complement a person's personal biochemistry and genetic makeup. For those diseases that were previously considered lethal and where treatment was either non-existent or largely unsuccessful, the discovery of DNA has essentially led to breakthrough drugs and treatments for patients with serious illnesses.</span>
