The correct answers are B & C. Silicon-32 is the parent isotope, which decays into phosphorus-32 (daughter isotope). The silicon-32 amount is halved every 170 years, so we can use this to determine how old the rock is. The amount of phosphorus-32 increases over time, but it is not equal to the amount of silicon-32.
Answer:
There is consistency of the current study's findings with that found in previous research studies.
Answer:
Error: The Methionine at the end of the chain
Explanation:
Hello! Let's solve this!
The start codon is AUG, this codon encodes Methionine. Therefore all proteins will start the amino acid sequence with Methionine.
In this case, the student placed the Methionine at the end of the chain, so that is the mistake. Methionine goes to the beginning of the chain.
Answer:
p53 gene is an important gene that regulates the proper functioning of the cell. This gene plays an important role in the cell cycle progression and acts as genome guardian.
Any mutation in p53 leads to the formation of the different types of cancer cells. The p53 gene is activated by teh phosphorylation at the particular sites. High levels of phosphorylated p53 in the cell indicates that the cells DNA is highly damaged and mutated.
Non native species are organisms that do not naturally occur in a given area. They may have been transferred either accidentally or deliberately from their place of origin to the new area through human activities.
Non native species may become invasive species if they cause harm to the economy, human health, or environment.
Control methods used to eliminate invasive species are:
1) mechanical - physically removing the invasive species or changing the habitat condition of the affected area.
2) chemical - using of pesticides, fungicides, or herbicides to kill off invasive species.
3) legislative - introducing the natural enemy of the invasive species. It may be a predator or parasite that is from its native range.
