Answer:
Modifying the accessibility of chromatic leads to complex regulation of eukaryotic gene expression.
Answer:
Homeostasis imbalance
Explanation:
Homeostasis is the ability of an organism to maintain stable internal environment. It is one of the major life functions. For example, the body has a way of regulating excess water in the body in form release of urine.
When the internal enviroment is not in equilibrium, it is called a homeostasis imbalance. It occurs when an organism is no longer able to maintain a fairly stable internal environment. Most this results as a result of diseases in the human body.
I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form to another, such as from the isotype IgM to the isotype IgG.
Answer:
D variations in individuals are not heritable
Explanation:
Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.
Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.
Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
