Explanation:
Fossils are the preserved remains of organisms that are found in rocks. The give clues to how the earth has evolved in geologic past and the nature of organisms that lived during that period in time.
A lot of biases are known with fossil preservation as a geologic record might not tally with phylogenetic relationship developed by biologists.
- Some fossils can become lost in the geologic record due to the dynamic nature of our planet. Earth materials can be eroded and weathered causing preserved fossils to be lost and exposed.
- Some organisms are naturally favored due to their physiology to be preserved as fossils in the geologic record. Others would be lost. This makes records of life in preserved as fossils highly subjective.

Explanation:
The monocot seed has one seed leaf while the dicot has two seed leaves. For example a peanut is a dicot while rice and corn are monocots. The roots of dicots show secondary growth which the roots of the monocots do not.
Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.
