<h2><u>Please </u><u>mark </u><u>BRAINLIEST</u></h2>

Explanation:

Like carbon, nitrogen has its own biogeochemical cycle, circulating through the atmosphere, lithosphere, and hydrosphere (Figure 5). ... In this symbiotic association, the bacteria become encased in nodules that grow on the roots of plants, through which nitrogen that has been fixed by the resident bacteria is obtained.

20 heterozygous purple flowering pea plants are crossed. If purple is dominant over white, what are the expected phenotypic resu
Elenna [48]
Let's call the colour alleles C for dominant purple, and c for recessive white.

We have crossed Cc with Cc.  So if we put that in a Punnett square, we'd have a CC, two Cc and a cc.  That would give us a 3:1 ratio of purple to white, so you'd expect 15 purple and 5 white flowers. :)

The image shows rock strata from three different regions on Earth. Identify all the layers that contain an index fossil
FrozenT [24]

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.
