The answer would be: <u>Molten material that cooled quickly.</u>
Igneous rocks are formed by the cooling of molten material. So we can cross out the last two choices. The rock has no identifiable crystals so it is most likely an Extrusive igneous rock. They form on the surface where they cool quickly.
Those that form underground are called intrusive rocks. They cool slowly allowing enough time for crystal formation.
Answer:
yes it helps controll the fishes depth
Explanation:
Fluid shift from vascular to interstitial can cause the water in blood is decreased, causing the other component level in blood seems to be increased(hemoconcentration).
In this case, hematocrit is one of the marker in laboratory that can be used for assessing hemoconcentration.
Answer:
cDNA library.
Explanation:
Genomic library may be defined as the collection of all the genomic DNA of an individual. The genomic library is constructed by the digestion of digestion of DNA fragments and there further transfer in the vectors.
cDNA library is prepared in case of eukaryotes because the complementary DNA is produced from the RNA. The eukaryotes DNA is interrupted with exons. In case of spider, the cDNA linrary is prepared because its DNA is interrupted with exons.
Thus, the answer is cDNA library.
