Answer:
Preservatives are the chemical substances which are added to the products like pharmaceuticals, paints, biological samples, foods and many other products to prevent the disintegration or rotting mainly caused by the growth of microbes or due to undesirable chemical changes.Preservations are of 2 types i.e. chemical & physical. Chemical preservation means addition of chemical compounds to the products. Physical preservation means process such as refrigeration & drying. Preservatives aims at decreasing the risk of foodborne infections, reduce microbial spoilage & to improve nutritional quality. Some physical methods used for food preservation include dehydration, freeze drying, refrigeration & UV-C radiation. Chemical And physical preservation are sometimes used in the combination.
The advantages of using the food preservatives are:
- Decrease the moisture content
- Increase the acidity
- Preventing the ripening process( naturally)
- Acts as an antioxidant
- Lowering the food waste
Main properties of ideal preservatives :
- It should not be poisonous
- It should not be irritant
- It should have physical as well as chemical stability
- Preservative must maintain the good compatibility with other ingredients used in the process of developing food
- It should acts as preservative in small concentration
- It should retains activity through food manufacturing, shelf life & usage

I'm like 99% sure because I know A and B happen in meiosis and a Google search says otherwise about C
A biologist would most likely concentrate on homologous features to find and analyse an evolutionary relationship between two species, finding homologous traits between species might help biologists to understand the evolution of animals, whereas concentrating on analogous features might help to compare the evolution of different species. Hope this helped!
Answer:
The congress leaders are working in the best interests of the environment.
Explanation:
<u>Contributions of the Congress leaders to the environment in 1970s-1980s .</u>
Spurred by the mass mobilization, within five years Congress had created some of the most consequential environmental legislation to date: the establishment of Environmental Protection Agency (1970), the Clean Air Act (1970), the Clean Water Act (1972), the Marine Mammal Protection Act (1972), and the Safe Drinking .
Before 1970, there were so many individuals and corporations in the United States who agreed with the mayor that the unavoidable price of change was pollution. However, Congress indicated its strong conviction in the 1970 amendments that economic prosperity and a safe environment are not mutually exclusive priorities.
Hence, the congress leaders worked are still struggling and working in the best interests of the environment .
Water loss ... This is because when you eat carbohydrates, they turn into glycogen which is then stored in your muscles for energy. For every gram of stored glycogen stored, you gain 2.7 grams of water. Therefore a low carb diet would result in weight loss due to water loss.
