Jenn and Clara are identical twins. Jenn developed schizophrenia when she was 19, but Clara shows no symptoms of the disorder an
d enjoys life as a college student. Jenn was sexually abused by an uncle at the age of 8 but Clara was never exposed to any abuse. While both have identical genes, the difference between the two may be due to:
Explanation: Epigenetics is the study of heritable changes in gene expression that occur without any accompanying changes to the basic DNA sequence, which ultimately results in a change in the observable characteristics (phenotype) without a change in the genotype(genetic traits).
Epigenetics creates a layer of control that determines which genes are active and which genes are dormant in particular cells in the body, and can be influenced by certain factors like age and environment.
The difference in genetic expression between Jenn and Clara could be attributed to Jenn's abuse when she was 8years old and this may have triggered Jenn's schizophrenia.
Biological equilibrium, applied to an ecosystem, denotes the state in which the organisms. are in balance with the habitat-type and with each other. Natural Biological Equilibrium is the. state of equilibrium resulting from "natural" processes, i.e., entirely random processes, and is. Is found among Producers, consumers and decomposers.
The so-called bioeconomic equilibrium is reached when net profit is zero, i.e. when the return from fishing is the same as could be achieved from switching to some other form of economic activity.The existence of a bionomic equilibrium(means both biological and economic equilibrium) is discussed in detail and is then illustrated in both numerical and graphical ways. Actually the bionomic equilibria are the points of intersection of the zero profit line with the biological equilibrium line.
