Multinomial logistic regression analysis was employed to evaluate the influence of each criterion of the phenotype alone or grouped. Results: a total of 219 individuals participated in the study. The most common frailty criterion was slowness in both frail and pr...
Although John’s DNA is about 97% Southern European, he’s got about 3% from North Africa, reflecting patterns of migration and the influence of Arabic trading with the Mediterranean. He’s also got maternal and paternal lineage of a type most common in the Middle East. ...
Question: What is ultimate causation in biology? Proximate Causation: In biology, proximate causation tries to explain an occurrence or result in terms of immediate factors. Simply put, proximate causation attempts to explain ''how'' something occurs. For example, the wing color of peppered moths...
What is the relationship between the two kinds of e Which characteristic of life pertains to your heredity information? Does the environment have an influence on the phenotype? Which of the following offer clues to evolutionary relationships among animals? a. gene sequences b. prot...
Recently, more precise definitions of severity by bleeding tendency or phenotype (as the 2 do not always coincide) have been proposed [11]. The bleeding phenotype of people with hemophilia, as noted above, is primarily determined by the baseline factor activity measurable in plasma; however, ...
How can gene regulation influence growth and development of an organism? What is meant by the term gene expression? Describe two forms of epigenetic gene regulation. What is a gene? Provide at least two different definitions. Define a gene and explain about its structure. Define and describe ge...
In an ideal world, we’d be able to see what happens to individuals both when they have insurance and when they don’t, but this would require at least two worlds. The best we can do is to give some people insurance and some not, while attempting to hold all other things equal. Thi...
Senescent cells influence the surrounding tissue microenvironment through dramatic changes in the proteins they secrete, a phenomenon known as the senescence-associated secretory phenotype (SASP). The SASP encompasses the upregulation and release of growth factors, cytokines, and proteases that can exert ...
While plurality of concepts and definitional vagueness can sometimes be a virtue in fostering research, they may also be problematic in some circumstances (Strunz2012). In the case of stem cell research, these problems manifest in at least three aspects: one “pedagogical”, and two epistemic. ...
What are the two main causes of mutations? How are U2AF1 mutations acquired? How are mutations acquired? Explain gene mutations. How do genetic mutations influence biological diversity? What is genetic variation? What are four possible sources of genetic mutation? How does genetic drift affect mut...
