Evolution is the changing of gene frequency in a population over time. Natural selection is where animals with advantageous characteristics produce more offspring‚ therefore passing down favoured genes. In the more developed parts of the world‚ medical care and access to food means natural selection is lesser‚ as selective forces that were there before e.g some diseases and predators‚ are no longer there. Therefore‚ some humans that have characteristics that would have previously meant they produce

We all are scared of change and find the worst attributes of everything. So naturally we become scared of gene editing and the possible outcomes like safety issues‚ unfair accessibility‚ eugenics and many more. We focus on the bad instead of the good. We don’t stop to think of the good it can bring us. So in response Arthur Caplan in his article‚ “Engineering the Better Baby‚” he talks about why the good outweighs the bad and how there are too many benefits to be worrying about possible dangers that

Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency. Quantitation of salivary amylase in these diseases has yet to be performed. It is also unclear whether the presence of starch in a meal protects salivary amylase from inactivation by the acidic

The benefits of transgenic animals to human can be grouped into areas: 1. Agricultural Applications Transgenesis will allow larger herds with specific traits. a) Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits (e.g.‚ increased milk production‚ high growth rate). Traditional breeding is a time-consuming‚ difficult task. When technology using molecular biology was developed‚ it became possible to develop traits in animals in a shorter

Rectal Prolapse A rectal prolapse happens when the inside of the final section of your large intestine (rectum) pushes out through your anal opening. This can result from weakened muscles that attach the rectum to the inside of your lower belly. Then‚ the lower part of your rectum turns inside out. At first a prolapsed rectum may be temporary. It may happen only when you are having a bowel movement. Over time‚ the prolapse gets worse. It will start to happen more often and cause uncomfortable

The most important component is the generosity of organ and tissue donors‚ and the courage of those whom receive the transplant. Transplantation goes back many Centuries‚ in the 9th Century BC Ancient folklore in most cultures describe
