Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)
Explanation:
The relationship between ionic bonds and cleavage is "as the ionic bond strength increases, cleavage will be more difficult".
There are ionic bonds between the minerals that held them together. Ionic bonds are the consequence of electrostatic fascination and electron exchange amongst positive and negative particles (cations and anions). Ionic bonding infers the development of requested crystalline solids and the cleavage of those solids will rely upon the quality of this bonding.
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
