Question

Fossils are
(a) fovea in the retina of vertebrate eye
(b) remains of organisms present in the rocks
(c) the fossa present in the bones
(d) foramen through which nerves pass

Answer 1

Answer:

remains of organisms present in the rock

Answer 2

Answer is option "b"

Explanation:

• Fossil remains have been found in rocks all things considered. Fossils of the least difficult organisms are found in the most seasoned rocks and fossils of increasingly complex creatures in the freshest rocks.  
• A fossil is the protected survives from a dead life form from a large number of years prior. Fossils are found in rocks and can be shaped from:  
• Hard body parts, for example, bones and shells, which don't rot effectively or are supplanted by minerals as they rot.  
• Parts of organisms that have not rotted on the grounds that at least one of the conditions required for rot are missing. For instance, dead creatures and plants can be protected in golden, peat swamps, tar pits, or in ice.  
• Preserved traces of an organism, for example, impressions, tunnels, and rootlet follow - these become secured by layers of sediments, which in the end become rock.
• So, the right answer is option b "remains of organisms present in the rocks."
