Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.

When cells in a body are not working properly and normally, they cause disruption in the body homeostasis.
Homeostatis is characterized as balance in the body but when there is any disturbance in the body, it breaks down the balance and cause imbalance. For example in the case of diabetes in which body fails to maintain the good amount of glucose in blood which results in imbalance the body which is why diabetic patients are asked to maintain and monitor their body sugar level to maintain homeostatis.
Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They have a pretty good idea of where an earthquake is most likely to hit, but they still can't tell exactly when it will happen.
Answer:
Letter B.
Explanation:
Aquaporins, also known as "water channels," are the main transport of water through the membranes of plant, animal, and bacterial cells. These channels allow the water to travel into and within cells and, at the same time, exclude the passage of ions and solutes.
What makes letter B the correct answer, is the form of transport and shape of the channel that allow water according to the osmotic gradient. In this model, letter A shows simple diffusion, while C and D seem to illustrate gated channels.
