Answer:
60%
Explanation:
Penetrance in genetics is defined as a proportion of individuals that carry a certain gene (mutation of the gene) with the expressed phenotype (trait). In the example above we wanted to know the penetrance of the PRSS1 Ala16Val mutation. Form 120 individuals, 72 of them expressed some evidence of pancreatitis (120-48). The proportion of them with the expressed trait can be calculated as 72:120=0.6 or 60%.
Answer:
all
Explanation:
Biogeochemical cycles are pathways by which nutrients flow between the abiotic and abiotic compartments of the Earth. The abiotic portion of the Earth includes the lithosphere (the geological component of the Earth) and the hydrosphere (the Earth’s water).
Ecosystems rely on biogeochemical cycles. Many of the nutrients that living things depend on, such as carbon, nitrogen, and phosphorous are in constant circulation.
Essential elements are often stored in reservoirs, where they can be taken out of circulation for years. For example, coal is a reservoir for carbon.
Humans can affect biogeochemical cycles. Humans extract carbon and nitrogen from the geosphere and use them for energy and fertilizer. This has increased the amount of these elements in circulation, which has detrimental effects on ecosystems.
Targeted therapies differ from traditional chemotherapy because they are based on specifc cells to treat cancer.
<h3>What are Targeted therapies?</h3>
Targeted therapies are personalized therapies used in precision medicine whose objective is to treat a health concern by killing specific injured cells.
Conversely, chemotherapy is not specific for cancer cells and this treatment can also kill normal cells.
In conclusion, targeted therapies differ from chemotherapy because they are based on specifc cells.
