Answer:
; (1.8 meters per minute)
Step-by-step explanation:
Use dimensional analysis to solve this problem.
The proper units of conversion are given in parentheses on this question: 100 cm = 1 m.
Start with the given value, 3 centimeters/1 second.
Convert this rate to meters/minute by multiplying 3 cm/1 sec by 1 m/100 cm.
The top and bottom units should cancel out, so that's how you know to put the cm units on the bottom to cancel out with the 3 cm on the top.
Multiply the fractions together. The "cm" units cancel out.
Now you want to make the bottom units = minutes. There are 60 seconds in 1 minute, so you can use to multiply with .
The "seconds" unit cancels out, so you are left with meters on the top and minutes on the bottom. Multiply the fractions together.
We want the rate to be meters per minute (1), so completely simplify this fraction and divide the fraction by (100/100), so the denominator is 1 min.

Explanation:
The first step of digestion begins the moment the food on your plate touches your lips and goes into your mouth, believe it or not, teeth are part of the digestive system! Your teeth help chew and grind the food into smaller pieces, which makes it easier to swallow. Saliva then continues to break down the food further by converting starches to sugars, with the help of the enzyme that is in saliva called amylase. Once this occurs the food particles that are left will be passed down to the esophagus. The esophagus is a muscular tube that is on average ten inches long and about one inch wide. It passes food down by using many different contractions to force food and liquids into the stomach. When the food reaches your stomach, it begins to churn and move which ends up grinding the food. To do this the stomach produces juices that break down the tissues of meat. This stomach juice is known as gastric juice, it is a mixture of acid, enzymes, and water. The stomach empties out a small amount of food every thirty minutes to the small intestine. The food stays in the small intestine for approximately ten hours. During this time, the food slowly dissolves into the blood. The blood then carries the digested food to all parts of the body. The inside of the small intestine is a wall made of hundreds of small fingers called villi. Each villus has its own tube to take in the dissolved digested food. Since some food remains after the food has been digested this food is passed on to the large intestine. These waste remains are passed out of the body through the lower part of the colon known as the rectum. Studies have shown that having a good diet is especially important to have a healthy colon, some foods to eat that are good for you are celery, lettuce, and cabbage.
I would personally eat the apple since a nice, juicy, and crispy apple sounds much more appetizing than a chocolate candy bar. The reason I would eat an apple is because if you are looking for a healthy snack and compare the nutrition facts it is surprisingly a closer call than I anticipated. The apple has 19 grams of sugar and the candy bar has 21 grams of sugar. Going off that the apple is a better choice. If we go off carbohydrates there are both 25 grams, so that would be by just choice if we go off that. If we look at all the nutrition facts and long-lasting effects in 2018 Journal of Food Composition and Analysis showed that processed chocolate had unsafe levels of cadmium and nickel. This is a huge long-term affect that can cause permanent damage in your body that you will not realize right away. When you eat an apple a day though there are many more positive health benefits for example, apples help with keeping a healthy good balanced gut health. They also provide 14% of the recommended daily use of vitamin C. Now a chocolate candy might solve your cravings for sugar but in the future, there are way more positive effects if you eat an apple instead of a chocolate. Considering all these factors I would rather eat an apple.
Is a virus considered a living thing? Why or why not?
Answer:
Explanation:
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
Answer: no they are not living
Explanation: Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell.

Scientists claim that viruses are not living. Which evidence supports the classification of viruses as nonliving?
Viruses are unable to change or evolve over time.
Viruses must use their host’s cellular machinery in order to reproduce.
Viruses cause many different types of diseases.
Viruses lack genetic material that can be passed to future generations.
Answer:
Viruses must use their host’s cellular machinery in order to reproduce
Explanation:
The evidence that viruses use their host’s cellular machinery in order to reproduce put viruses in non living category. Thus option B is correct.
What are viruses?Viruses are microscopic infectious agents that contain genetic material, either DNA or RNA, and must invade a host in order to multiply.
Living things reproduce. Cells generally reproduce by replicating their DNA. Unlike cells, viruses do not have the tools to replicate their DNA.
But they have found other ways to create new viruses. This is done by introducing viral genetic material into the host cell.
Many scientists claim that although viruses can use other cells to reproduce, viruses are still not considered alive under this category. This is because the virus does not have the tools to replicate its genetic material on its own.
Therefore, scientists consider virus as non living because they do not have their own machinery to replicate their genetic material. Thus. option B is correct

Will an object with a large mass require more or less force to be stopped?
Why?
Answer:
Yes
Explanation:
Heavier objects (objects with more mass) are more difficult to move and stop. Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.
What effect does waste water treatment have on land
Answer:
The discharge of effluent from wastewater treatment plants (WWTPs) has major detrimental effects on the health of aquatic ecosystems. WWTP outfall can deposit large amounts of organic matter and nutrients into receiving waterways. Increased nutrient loading can lead to eutrophication (20) and temporary oxygen deficits (35)

Which conclusion is best supported by this information? E. Coli is a harmful bacteria that can be killed by exposure to oxygen. E. Coli is a helpful bacteria that can be killed by exposure to oxygen. E. Coli is a harmful bacteria that can be killed by high temperatures. E. Coli is a helpful bacteria that can be killed by high temperatures.
Answer:
The correct answer is: E. Coli is a harmful bacteria that can be killed by high temperatures.
Explanation:
E.coli or Escherichia coli is a gram-negative bacteria that are normally harmless but there are many strains that cause harm to individuals including humans. These bacteria come in contact with organisms through contaminated food or water and cause diarrhea and other illnesses inside and outside of the intestine.
These bacteria can be killed by the high temperature as they are not able to live at a high temperature that is the reason high temperature is used to decontaminate the water or places that are at high risk of exposure to the bacteria.
Answer:
the correct answer is E. coli is a harmful bacteria that can be killed by high temperatures. Or C
