Answer:
As nutrients, protein is overemphasized and carbohydrates are underrated in terms of their importance in our diets. Most people in the United States now eat more protein than their bodies need, and, somehow, carbohydrate-rich foods such as potatoes and bread have gotten a bad name for being fattening. Yet protein from animal sources often comes in foods that contain significant amounts of saturated fatty acids. And the only carbohydrate-rich foods that are truly fattening are those laden with fats and added sugar, such as pastries, cookies, and baked potatoes heaped with sour cream.
In fact, there is some evidence that diets high in carbohydrates may help reduce the risk of heart disease. Thus the Eat for Life guidelines suggest not to eat any more protein than you already do and to increase the amount of carbohydrates you eat to compensate for the lower amount of fat that your diet will contain.
This chapter presents the evidence that increasing the proportion of carbohydrates in the usual American eating pattern at the expense of fat will tend to lower chronic disease risk. It also discusses some of the health claims made for dietary fiber, a group of substances that are made up mostly of complex carbohydrates.
The answer is operon. These set of genes are transcribed together because they share a single promoter and operator. Therefore they are transcribed into one mRNA and translated together. These genes are, therefore, expressed together at all times. Examples are the tryptophan and lac operons of Escherichia coli
Hello, that is a very good question!
Back then there was no such thing as 'birth-control', hence they never actually prevented pregnancies, of course there were services that provided 'different' penetration but that could also result in pregnancies.
The popular method of not giving birth [prevent pregnancy] was to kill the baby while still carrying [termination], in other words have a miscarriage.
There many various methods during that time (herbs, beating, old cloth hanger).
Hope this helped,
