Answer:
A fossil is remain or impression of dead plants or animals which have lived thousands of years ago it can also be described as any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants
Types of Fossils. Fossilization can occur in many ways. Most fossils are preserved in one of five processes preserved remains, permineralization, molds and casts, replacement, and compression.
i hope this is helpful
if it is please mark me as brainliest :)
Definite volume is doesn’t possess a definite volume so therefore the answer is c
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.
One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
Answer:
a glass of muddy water
Explanation:
Pure substances contain only one element or compound.
Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.
The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.
Hope that helps.
