Hi,
By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.
Option c) is the correct option above.
<span>c) Fossils give information about the time period in which organisms lived in the past.

Answer:
Since the beginning of life of the first multicellular organisms, the preservation of a physiologic milieu for every cell in the organism has been a critical requirement. A particular range of osmolality of the body fluids is essential for the maintenance of cell volume. In humans the stability of electrolyte concentrations and their resulting osmolality in the body fluids is the consequence of complex interactions between cell membrane functions, hormonal control, thirst, and controlled kidney excretion of fluid and solutes. Knowledge of these mechanisms, of the biochemical principles of osmolality, and of the relevant situations occurring in disease is of importance to every physician. This comprehensive review summarizes the major facts on osmolality, its relation to electrolytes and other solutes, and its relevance in physiology and in disease states with a focus on dialysis-related considerations.
He based his hypothesis on a statement made by a dairymaid.
The statement " Each gene in the human genome codes for a single protein. "is just wrong, as according to the basic knowledge of human genome, o<span>nly about 2 percent of the genome codes for proteins. This answer does make difference and clearly explaines why the previous one is wrong. Hope you will find it helpful!</span>
1. The virus attaches itself to a host cell
2. The virus inserts its nucleic acid into the host cell
3. The virus nucleic takes over the host cell and makes virus parts
4. The cell creates more viruses
5. The cell bursts, releasing the new viruses
