okay so I'm pretty sure about these answers!
I think it is called the METAMORPHIC ROCK.
It formed not only when the pressure changes but also with the heat.
Good luck :)
The right answer is True.
The history of life on Earth shows a succession of fossil species during geological time, each species appearing and developing before disappearing. This is why fossils constitute an archive of earthly history and are used to establish the divisions of geological time.
To date the rock in which they are, fossils are not useful if they belong to a group or species that has had a very long life. On the other hand, those who have lived in very short time intervals are useful for dating because they represent a precise time. These fossils are called stratigraphic fossils.
To qualify as a stratigraphic fossil, a species must:
• have had a large geographic extension (allowing correlations),
• have existed for a short time at the geological time scale,
• have been abundant (a necessary condition for finding fossils)
For example, ammonites are used to date Jurassic and Cretaceous rocks.
Answer:
The alleles I a and I b are the alleles that works for identifying unique antigen.
Explanation:
These alleles are generally found as deposition on the surface of the red blood cells. Again, these antigens are different form made from one protein. The Ia and I b alleles are found to be co-dominant and allele i is recessive. In human beings three different alleles are there, Ia, I b and I. The alleles are nothing, but a form of gene. Many genes are there having different function but are present in the same position. Humans are diploid, hence have two allele, each from one parent it has been inherited.
