Artemon [7]3 years ago

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine. About 30% starch digestion takes place in the mouth cavity.

Nutrition &amp; Health: Nutritional Claims
nikdorinn [45]

Answer:

Explanation:

Lab: Reactions  

The goal of this lab is to demonstrate the effects of changing temperature and particle size on the rate of a chemical reaction. The purpose of this lab is to plan and perform controlled tests of multiple variables using repeated trials during an investigation about reaction rate. This is an inquiry lab. My hypothesis is that the effects of the different variables will have a major effect on the outcome of the results. The temperature will change dramatically by the multiple factors it will be exposed to. The different variables include the substance in the container, the temperature in the container. Also, the temperature of the room can affect the ending temperature of the cylinder after the experiment. The controlled variables are using the same thermometer and the amount of substance put into the vial.  

 

The materials needed for the lab are listed above. The steps of the experiment do not change, only the substances used for the experiments. This includes started with the beaker and filling it with the cylinder with water. Then you use the thermometer to check the degree of the water. Then you use togs and place the beaker filled with water onto the hot plate. You turn on the hot plate and wait for the water to heat up for 5 minutes. Then you use togs and remove the beaker from the hot plate and turn the plate off. Then you use the thermometer and check the temperature of the heated water. You put the tablet into the heated water and time it. You repeat this process with all of the substances.  

You should record all of the processes of the lab and write it all down.  

Table A: Baseline Data for Tablet in Room Temperature Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 50 50 Trial #2 250 20 0 52 52 Trial #3 250 20 0 51 51 Average Time for Tablet to Dissolve 51 Table B: Time to Dissolve Tablet in Hot Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 40 0 22 22 Trial #2 250 40 0 24 24 Trial #3 250 40 0 20 20 Average Time for Tablet to Dissolve 22 Table C: Time to Dissolve Tablet in Cold Water Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 4 0 84 84 Trial #2 250 4 0 89 89 Trial #3 250 4 0 85 85 Average Time for Tablet to Dissolve 86 Table D: Time to Dissolve Tablet When Quartered Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 41 41 Trial #2 250 20 0 44 44 Trial #3 250 20 0 41 41 Average Time for Tablet to Dissolve 42 Table E: Time to Dissolve Tablet When Crushed Volume (mL) Temp. ( oC) Start Time End Time Elapsed Time (s) Trial #1 250 20 0 18 18 Trial #2 250 20 0 18 18 Trial #3 250 20 0 15 15 Average Time for Tablet to Dissolve 17 Summary Tables Table F: Summary Table for the Effect of Temperature Volume (mL) Temp. ( oC) Average Time (s) Hot water 250 40 22 Room temperature 250 20 51 Cold water 250 4 86 Table G: Summary Table for the Effect of Surface Area Volume (mL) Temp. ( oC) Average Time (s) Tablet form 250 20 51 Quartered 250 20 42 Crushed 250 20 17

The different substances used in the experiment reacted differently based on the heated water and conditions of the outside temperature. This was affected by all of the variables. I did not do any background research before doing this experiment so I do not have any prior experience on this topic. My hypothesis was correct after conducting the experiment. This constantly changed based on the variables and substance used.

What percentage of the US population is estimated not to engage in 30 minutes of low-to-moderate physical activity?
spin [16.1K]

Answer:

The estimated percentage is 75%.

Explanation:

It is very common for American people to have a <em>sedentary lifestyle.</em> This is especially true for <em>people who are working in the managerial position.</em> The <em>availability of fast food</em> everywhere is also one factor. It is said that 75% of the US population is estimated not to engage in 30 minutes of low-to-moderate physical activity. This estimation fluctuates according to <u><em>age, gender and occupation.</em></u> Another contributing factor to having less physical activity is the <em>rate of unemployment.</em> People who are unemployed find it hard to focus on exercise or physical activity. Instead, they divert their energy towards looking for work.

It is essential to have <u><em>at least 30 minutes of low-to-moderate exercise 5 times a week in order to stay healthy.</em></u> America's situation makes them more susceptible to chronic diseases such as diabetes, cancer and obesity.
