Answer:
D. The prepackaged meats have modified atmosphere packaging that has excluded oxygen gas, which would promote the growth of spoilage organisms.
Explanation:
Meat is an animal products that serves as a source of protein for humans. It is very important that meat is well preserved to prevent the consumption of spoilage microorganisms.
Meats are prepackaged for the following reasons.
a. To keep it fresh: Meat comes with a bright red colour due to the presence of myoglobin which is a protein in meat. This colour makes the meat attractive to consumers when they want to purchase it. When myoglobin is exposes to oxygen, it reacts with the atmospheric oxygen giving the meat a dullish brown colour. This makes the meat less attractive .
In other to preserve this fresh meat colour, meat prepackaged using modified atmospheric packaging for example vacuum packaging in which oxygen is absent. This preserves the colour of the meat and keeps it fresh.
2. Prevent the growth of spoilage microorganisms: Meat contains proteins and the proteins tend to be attacked by spoilage microorganisms, for examples bacteria such as Listeria monocytogenes. In order to prevent this, meat is prepackaged with modified atmospheric packaging thereby making it hard for spoilage microorganisms to grow.
Answer:
Scientific studies has found no bases for the claim.
Explanation:
The rumor that vaccines is link to autism spectrum disorder has no bases because it has not been proven scientifically.
It should be noted that before a notion can be accepted scientifically, it must pass through observations, gathering of data, forming and testing theories, and interpreting results.
But the news going around that vaccine is link to autism spectrum disorder, didn't pass through those processes, that's why it is not scientifically accepted.
Note that, autism spectrum disorder is a disorder that affects communication, behavior, thinking and feeling.
