Explanation:
The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.
Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.
- Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
- Tool man also grazed the surface of the earth just a few thousands to a million years.
- We are able to find their fossils in rocks because they have lived in some certain geologic periods.
- Here we are using the fossils to date the rock and this is called relative dating

Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.
Answer:
In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).
Explanation:
The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.
This can be tested by making a Punnett square for this cross:
<u>GGHHII X gghhii</u>
Alleles GHI GHI
ghi GgHhIi GgHhIi
ghi GgHhIi GgHhIi
Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi
