Explanation:
Zelené řasy (Chlorophyta v širším smyslu)[pozn 1] je významné oddělení jednobuněčných i mnohobuněčných stélkatých zelených rostlin. Představují blízké příbuzné vyšších rostlin, které se z jedné linie zelených řas vyvinuly. Pokud vyšší rostliny do zelených řas neřadíme, pak jsou zelené řasy nepřirozenou, tzv. parafyletickou skupinou.[1][2] Proto se v novějších systémech do taxonu zařazují i vyšší rostliny[3] a nový smysl (= zelené rostliny) se odráží i v pozměněných názvech – Chlorobionta nebo Viridiplantae. Tento článek však pracuje s tradiční parafyletickou variantou. V tomto smyslu je známo 500 rodů a 16 000 druhů zelených řas.[4]
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.

Workers in the industrialized sectors laboured in factories rather than in scattered shops or homes. Steam and water power required a concentration of labour close to the power source. Concentration of labour also allowed new discipline and specialization, which increased productivity.
