Which of the following can scientists determine by comparing fossils from different layers of sediment? i exactly how many organisms were alive during a given time period ii the order in which different types of organisms appeared on earth lll how different species have diversified over time

By comparing fossils of different primate species, scientists can study how different species have diversified over time. Almost all sediment is either laid down horizontally in bodies of water like the oceans, or on land on the margins of streams and rivers. Each time a new layer of sediment is deposited it is laid down horizontally on top of an older layer. With this events, Geologists can established a set of principles that can be applied to sediments and to determine how these features evolved through time.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

your answer is c) plasma
