Answer:
Unsure what this is asking but yes, it does.
A student wants to prove that amphibians appeared on earth before birds. The student should use the fossil findings as evidence to provide the most reliable information about the periods when amphibians and birds appeared on earth. Fossils would throw light on the internal body structures that bear the closest similarity to either the amphibians or the birds. The radiocarbon dating of the fossils will reveal its age. This can be used to figure out the time of divergence of the two types.
Male cones grow near the<u> lower region</u> of the plant, while female cones are located near the<u> top of the tree.</u>
Sexual Reproduction in Gymnosperms :
The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.

The mass of one atom of carbon in the correct number of significant figures is 1.99×10-²³. There are four significant figures each in both the atomic mass of carbon (12.01 g) and Avogadro's number, so the answer must also have 4 significant figures. The operation is shown below:
<span>12.01 / (6.022x10²³) = 1.994x10</span>₋²³<u />
