Answer:
Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.
Explanation:
Correct answer: Adequate intake
It is a recommended intake value that given based on experimentally determined approximation or the estimates of the nutrients intake by a group of healthy people.
It becomes an important guide in the absence of enough scientific evidence in order to establish an estimated average requirement. Adequate intake of a nutrient is determined after a lot of observation and research.
Hence, the correct answer would be Adequate intake.
Answer:
Mineral composition, Soil pH, and Soil Texture
Explanation:
The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
Answer:
Prokaryotic are organisms that consist of a single prokaryotic cells and Eukaryotic cell are found in plants, animals, fungi and protists.
Explanation:
they are range from 10-100 micrometre in diameter, and their DNA is contained within a membrane-bound nucleus.
