When a geologist working in stratified rocks observes a limestone bed with oyster fossils overlain by beds with clam and echinoderm fossils indicative of marine conditions, the fossils probably indicate ----- that the environment had changed as the sea level rose and it displaced the oysters environment with marine conditions represented by the clams and echinoderms.

<span>The evolution of a long neck in giraffes is an example of natural selection in that the giraffes with long necks would be able to eat more leaves from higher trees and thus be more successful.</span>
The probability that they both were planted alone is 0.3325.
<h3>What is genetic probability?</h3>
Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.
In this case:
- Number of plants planted alone = 134
- P(both plants were planted alone) = 134/232 x 133/231 = 0.3325
So the probability that both were planted alone is 0.3325.
