Answer:
d. there is a relationship between smoking and lung cancer
Explanation:
a) it is NOT true becasue although the research show that is more likely to get lung cancer for smokers, it DOES NOT show that all smokers get cancer.
b) it is NOT true becasue altough it is very possible that smoking contributes to lung cancer, the research DOES NOT prove that smoking is the cause of lung cancer, it only indicates a relationship between smoking and lung cancer that is evidence that smoking contributes to lung cancer but it is not irrefutable proof.
c) it is NOT true becasue the research finds a relationship between lung cancer and smoking, but it is not focused in explaining smoking predispositionon. It does not investigate predispositions in people to smoke.
(ANSWER)
Choice B, because the beetle gets energy from A. The racoon gets energy from the beetle, B, and corn. And B gets its from blackberries.
The correct answer is "Phylum Urochordata: xi = 25; yi = 77".
The table presented in this exercise can be used as a tool to examine any connection between the microRNA (miRNA) diversity and the morphological complexity in a phylum. The Xi column represents the average number of miRNAs in a phylum, while the Yi column represents the average number of cell types in that phylum. The eight observation of this table refers to the data obtained from the phylum Urochordata.
MicroRNAs are small non-coding RNAs which regulate gene expression post-transcriptionally. They are used as phylogenetic markers as they have a very low rate of evolution. Also, they are very useful because it has been shown that phyla with very high levels of morphological innovation have high numbers of miRNA concentration.
The natural element _IODINE_ is important in the synthesis of thyroid hormone; lack of it will lead to a goiter.
The answer would be kingdom
