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:

  1. Decrease the moisture content
  2. Increase the acidity
  3. Preventing the ripening process( naturally)
  4. Acts as an antioxidant
  5. 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

Why does passive immunity for a new-born only lasts for a short time?​
diamong [38]
The recipient will only temporarily benefit from passive immunity for as long as the antibodies persist in their circulation. This type of immunity is short acting, and is typically seen in cases where a patient needs immediate protection from a foreign body and cannot form antibodies quickly enough independently.

Hope this helps!

Have a great day!

A new disease has recently been discovered in a village, and you have been brought in to investigate. The disease appears to pas
12345 [234]

Answer:

The pathogen replicates without using host cells replication machinery, and it is directly transmitted

Explanation:

We could infer that the disease is caused by bacteria, as we know that it can be cured by using <u>antibiotics</u>. Antibiotic a group of drugs capable of destroying bacterias or inhibit their growth.  

Bacterias have many different ways of propagating, one of them is by contact:

  • Direct contact: This occurs when people touch or kiss a sick person,  or there is an interchange of liquids and corporal fluids (such as sweat or blood) between the healthy person and the sick person.
  • Indirect contact: the transmission occurs through an object.

Bacterias do not need any other living being to reproduce and they are able to survive under extreme conditions. Bacteria do not need any host to replicate.

In the exposed example, the disease is cured by using antibiotics, and its transmission is by direct contact, such as handshaking or touching.

Write a paragraph about how
den301095 [7]

Answer:

Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.

Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.
