Food should be thrown out or refrigerated after being left out for 2 hours. All reheated food should be heated to 140 degrees F. Make sure you practice good hygiene, by washing your hands, washing utensils before using again, heating properly and storing properly. 1.3 Personal protective clothing (ppe) should be worn when handling food to prevent the spread of germs or bacteria for example if you have a small cut on your hand it could get infected or you could spread infection onto the food therefore spreading to the service user. Using aprons will protect your clothing from becoming dirty but also prevent any bacteria on your clothing spreading onto surfaces and the food you are preparing. Gloves and aprons will also protect your skin from burns from oils, very hot liquids and food containers.
By touch they feel slippery and sticky. Their mucous like skin is so thin because, even though they have lungs, they absorb oxygen through their pores. They usually are unable to grown larger than the length of a man’s arm. However, reptiles can easily match the size and height of a man. Reptiles have a rough brittle exterior made from scales to protect the delicate skin that lies beneath, which makes them less susceptible to predators.
Sandwiches are a better choice because they maintain a lot of carbohydrates. This would fill the children up and keeps their brain functioning. On the food pyramid carbohydrates are at the bottom this is because you need to intake carbohydrates than any other food group. Having a piece of fruit would be good to have as its one of your 5 a day, and they contain the nutrients your body needs. Fruit is good for our bowels and would help the children go to the toilet regularly, this would prevent constipation.
Conditions that must remain constant in this experiment include the temperature of the water baths and the volume of peas and beads in the respirometers. The general gas law states that if temperature and volume remain constant, then the pressure of the gas will change in proportion to the number of molecules of gas present. 2. Water moves into the respirometer pipettes because as oxygen is consumed by the peas, the pressure within the pipettes will decrease and thus the negative pressure will draw the water into the pipette. It is important to correct the readings from the peas because the glass beads are used as a control in which no changes should occur in CO2 and oxygen levels due to their abiotic nature.
Rohm and Haas Case Write Up 1) What is Kathon MWX really worth to users? (.5 - .75pg) Kathon MWX was developed to kill bacteria and fungi in tanks under 1000 gallons, and is meant to save the customers money and time, but also provide convenience and safety. This product extends the life of fluids, allowing the customer to save money on new fluid, metalworking fluid concentrate, and waste disposal. These cost savings are described in detail in Table 1. By extending the life of fluids, the customer also saves time on draining and refilling fluid tanks, thus reducing downtime.
The number of koalas is determined by the number of trees. Koalas are highly specialized to survive only in one type of habitat, in woodland with plenty of eucalyptus trees, also known as gum trees. Places like that provide the koala with food, water, safety from ground predators, and all other needs. Koalas do not have dens, tree- holes, or nests. They sleep, eat, and breed on the branches.
They are able to change in green and brown patterns in only a matter of minutes. Unlike other amphibians and reptiles they do not change colour according to their background colour, instead it is due to temperature and moisture levels, yet it still provides them with a very successful method of camouflage, allowing them to be overlooked by potential predators, (Hill 1998). The Chilean four-eyed frog (Pleurodema thaul) has developed another form of disguise, rather than hiding itself it attempts to warn off predators by pretending it is a much larger organism, and therefore perhaps a potential threat to anything wishing to prey upon it. It achieves this through the aid of a bright pair of spots located on it’s rump. When the frog is seated these spots are not visible, however when threatened it will lower it’s head and lift up it’s rump – displaying the spots.
Because of all these differences, no one can really say, “a dog is better than a cat, because…” and vice versa as a proven truth (You may voice it aloud if you are stating it as an opinion). Although the statement above is rather impossible to say truthfully as a fact, you cannot deny that a cat is typically a much more convenient pet than a dog. For one, cats cannot bark. This is a very good quality for a pet to have, because then you are not kept awake at night by it making a cacophony of sounds at every single random creature seen moving around outside. Also, cats are not able to irritate your neighbors in the loudness sense, because they generally do not make many powerful sounds.
Example: Although most people prefer to have a dog as a pet than a cat, cats make great pets. To begin with, cats require little care. They do not need to be house broken because cats innately seek to relieve themselves on the same spot and even bury their excrement. All the owner needs is to provide a litter box, and he can forget about messiness. Additionally, cats do not require to be walked like dogs do.
Fish are very sensitive to chlorine and other impurities in tap water. Allowing the tap water to sit out for a few days will rid it of any impurities and you will then be able to fill up your aquarium. The items discussed are very easy to acquire and even afford, but can make the difference in life and death for your fish.
