The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
Answer:
rr
Explanation:
Alleles that are recessive will be lower case. Alleles that are dominant are upper case. Since we have two recessive alleles represented by 'R', the alleles would be written as 'rr'.
For most turtles the incubation ranges from 45 and 75 days.
I think you forgot to add an image, there’s no context for anyone to answer your question
Chemical work, mechanical work, and transport work.
Chemical: An example would be the ATP building large molecules such as proteins for the cell (s)
Mechanical: An example of this would be the contraction of your muscle (s). The reason for this is because In your muscle cells, ATP transfers phosphate groups to certain proteins which allows them to then change shape starting a chain of events leading to your muscles contracting
Transport: An example would be transport work pumping solutes into a cell membrane.
Hope this helps! :)
