(Suited for Spacewalks - Adapted from NASA)

Following Gemini, the Apollo program added a new dimension in spacesuit design because actual spacewalks, on the surface of the Moon, were now to occur for the first time. As with Mercury and Gemini space garments, Apollo suits had to serve as a backup pressure system to the space capsule. Besides allowing flexibility in the shoulder and arm areas, they also had to permit movements of the legs and waist. Astronauts needed to be able to bend and stoop to pick up samples on the Moon. Suits had to function both in microgravity and in the one-sixth gravity of the Moon's surface. Furthermore, when walking on the Moon, Apollo astronauts needed the flexibility to roam freely without dragging a cumbersome combination oxygen line and tether. A self-contained portable life-support system was needed.
The Apollo spacesuit began with a garment that used water as a coolant. The garment, similar to long johns but laced with a network of thin walled plastic tubing, circulated cooling water around the astronaut to prevent overheating. A multi-layered pressure garment was worn on top of the cooling suit. The innermost layer of this garment was a comfort layer of lightweight nylon with fabric ventilation ducts. On top of this was a layer of neoprene-coated nylon surrounded by a nylon restraint layer. This layer contained the pressure inside the suit. Improved mobility was achieved by bellow-like joints of formed rubber with built-in restraint cables at the waist, elbows, shoulders, wrist, knees, and ankles. On top of the pressure layer were five layers of aluminized Mylar for heat protection, mixed with four spacing layers of non-woven Dacron.
Above these were two layers of material for additional thermal protection and a non-flammable layer of Teflon coated in a fibrous cloth. The outermost layer of the suit was white Teflon cloth. The last two layers were flame resistant. In total, the suit layers provided pressure, served as a protection against heat and cold, and protected the wearer against micrometeoroid impacts and the wear and tear of walking on the Moon.
Capping off the suit was a communications headset and a clear plastic pressure helmet. Slipped over the top of the helmet was an assembly consisting of sun-filtering visors and adjustable blinders for sunlight protection. The final items of the Apollo spacesuit were lunar protective boots, a portable life-support system, and custom-sized gloves with molded silicone-rubber fingertips that provided some degree of fingertip sensitivity in handling equipment.
The life-support system, a backpack unit, provided oxygen for breathing and pressurization, water for cooling, and radio communications for lunar surface excursions lasting up to eight hours. Furthermore, back inside the lunar lander the life-support system could be recharged with more oxygen and battery power for additional Moonwalks.
During the Apollo program, 12 astronauts spent a total of 161 hours of extravehicular activities on the Moon's surface. Additional extravehicular activities were spent in microgravity while the astronauts were in transit from the Moon to Earth. During a total of four hours, one astronaut, the command module pilot, left the capsule to retrieve photographic film. There was no need for the portable life-support system away from the Moon, as those astronauts were connected to the spacecraft by umbilical tether lines supplying them with oxygen.

1. Wash Your Hands Carefully

Proper hand washing can get rid of almost half of all foodborne illnesses. . . .

2. Don’t Cross-Contaminate

When raw meat comes in contact with other foods, it can cause cross-contamination. Don’t use the same utensils for meat and other foods. . . .

3. Keep Hot foods Hot

Harmful bacteria are destroyed by cooking food properly. Beware of raw or partly cooked meat.

4. Keep Cold Foods Cold

Meat, fish, milk, and eggs should be kept cold. . . .

5. Wash Fruits and Vegetables

And keep in mind that washing may not remove all contamination.

What effect did the author most likely intend to achieve by ordering the information in this way?

Answers

Answer:

By giving cooking and serving advice about how to keep the food warm/hot and edible.

Explanation:

Totes made out of cloth can be a breeding ground for bacteria. “Juices can drip from packages of raw meat and contaminate the outside of the packaging and the bag,” says Sana Mujahid, PhD, manager of food safety research at Consumer Reports.

A safer move: Don’t switch back to plastic. Instead, wash your cloth bags frequently in the washing machine using hot water. At the store, consider slipping the raw meat you buy into a plastic produce bag and sealing it tightly before you put it into your cloth grocery bag at checkout. If you want to be even more cautious, pack all uncooked meat, poultry, and seafood in disposable bags, or designate one cloth bag for such foods.

    Whatever you do it’s up to you, your skills help you complete the project or get the job that you are working on done. No matter your skill set there will always be a job for you, fixing a pot hole or setting out traffic cones for the other workers but what ever you are capable of doing there will be a way for you to help and do your job based off what you know. You will always see a progression in construction on what you are doing immediately because things change very fast and you will always see a new out come or difference in your work. Construction also helps you develop skills such as communication skills as to talking to new people and collaborating with them to do new jobs. Construction is a team effort People who don’t have the necessary skills to work well or communicate with others are going to have a hard time in the process, team players help build up the team and foster good communication and better construction. It also helps you with team work and problem-solving skills, there is always a way to finish and get the job done and that’s what the team is for to help each other finish and create a strong progression throughout the ending. As you work your way up through the ranks, you’ll find new ways to use both your mind and your hands to get the job done. For those who are relatively new to the field, pay attention to the guys who have been in construction for decades. They know their stuff because they’ve been working hard, observing and learning all along the way.

Explanation:

"I hope this helps, let me know if you need any more help"!

Answer:

It should come as no surprise that construction is a physically demanding job. Considerable strength and stamina are essential for carrying out many tasks on a job site. Almost 50 percent of construction jobs will require heavy lifting work and physical strength.  Workers will need to possess proper posture and form to effectively and safely conduct manual labor, both indoors and outdoors.  Along with physical strength, construction workers must have hand-eye coordination and dexterity. Construction jobs require sitting, lying, and standing for long hours. Limb coordination is needed to move both arms and legs quickly and accurately in any environment.  Construction work also requires excellent eyesight.  Technical knowledge is just as important as physical competence. About 36 percent of contractors fail due to a lack of adequate training and inexperience with particular types of work. Familiarity with the materials and tools needed to fill a wide range of construction services is invaluable to a worker’s skill set.

Photosynthesis and Cellular Respiration

The processes of photosynthesis and cellular respiration are interdependent—each process is necessary to fuel the other. The chemical products of photosynthesis are the chemical reactants of cellular respiration, and the products of cellular respiration are the reactants of photosynthesis.



During photosynthesis, plants, algae, and photosynthetic bacteria—together called producers—create their own food by capturing light energy from the Sun to make molecules of glucose. Organic molecules, including glucose, can then be stored as food to be broken down by cellular respiration when energy is needed.
All living organisms perform some kind of cellular respiration. During cellular respiration, chemical pathways containing organic molecules such as glucose are broken down to release energy in a quickly usable form. Essentially, cellular respiration is the opposite of photosynthesis.
