In An Arctic Landscape, Get To Sea Ice

Most foods spoil because of the growth of microbes. Preserving food is an attempt to limit microbial growth. Food can be preserved by drying, salting, chilling, or storing in air-tight containers.

• Drying is the most effective because microbial growth is inhibited.
• Salting is effective because it removes moisture, creating an environment where microbes cannot survive.
• Sugar coating can prevent bacterial cells from functioning correctly.
• Storing in air-tight containers is less effective because there are probably a lot of microbes on the food before you put it in the container. Some microbes are anaerobic, meaning they don't need oxygen.

Preservatives are used in foods to extend their shelf lives. One of McDonald's Big Mac in Iceland is an example of a long-lasting processed food. It has been on display since 2009, in a glass box. Preservatives that has been discontinued by McDonald's are:

• calcium propionate that prevents mold growth on bread.
• sorbic acid that also inhibits mold from cheese
• sodium benzoate, which inhibits the growth of bacteria in the Big Mac special sauce.

While we are on a flight, there are plenty of changes that we can experience:

• Change in brain chemistry and memory due to the deficiency in oxygen.
• Cognitive deficits in people who are already ill.
• Increased tiredness and more yawning during the flight.
• Deterioration in vision, dryness of skin, change in taste of food due to a reduction in the sensitivity of our taste buds and a decrease in the sense of smell.
• Change in air-pressure makes passengers generally uncomfortable with the sitting.

Mood swings, along with general anxiety or nervousness are common among flight passengers.

• Less oxygen can increase the effects of alcohol and the overall anxiety. These factors contribute to emotional changes, which can make people less friendly, more stressed out and lethargic.
• People are also prone to severe mood swings, like having extreme emotional reactions to movie scenes which would otherwise appear normal to them.

In Plane Crazy, he does not have white gloves or oversized shoes. He didn't even have a consistent number of fingers.

• Mickey's shoes, his trademark footwear, is introduced in the second cartoon, The Gallopin' Gaucho (1928), and stayed ever since.
• His gloves made their first appearance as part of his stage costume in The Opry House (1929). His gloves became a permanent fixture in When the Cat's Away (1929), and has remained part of his design ever since.
• His eyes first occupied his entire face but were redesigned as small, black ovals giving Mickey a greater range of facial expression.

The Band Concert (1935) was the first standard Micky Mouse cartoon in color with a signature red shorts. By this time, Mickey's mischievous prankster actions had passed on to Donald Duck. Mickey had transitioned into the role of an endearing romantic and humble hero.

Over time Mickey's facial features softened and appeared younger while his personality continued to mature. The Brave Little Tailor (1938) was the peak of Mickey's career, and at this point, Mickey became more curious and wholesome.

Today Mickey Mouse is optimistic, brave, and lovable in his iconic red shorts, yellow shoes, and white gloves.
