A researcher dried a feedstuff and determined that it contained 10 percent moisture. he took 1 gram (dry) of it and combusted it in the bomb calorimeter. the calorimeter contains 1 kg of water. The temperature was raised 2.7 degrees centigrade. Two kilograms (2000 grams) of dry matter of the material was fed to a pig each day for several days. the fecal collections of the pig averaged 200 grams dried per day for the last few days. the feedstuff analyzed 2.41 percent nitrogen (dry basis); the feces (dry basis) analyzed 4.6 percent nitrogen. (hint: the feedstuff contained _____ grams protein, the feces contained _____ grams protein.)

Answers

Answer 1

Answer:

Explanation:

The objective of the information given is to calculate the apparent digestible dry matter present in the feedstuff(%) and the apparent digestibility of the protein?

From the given information:

The apparent digestible dry matter present is:

[tex]=\dfrac{ (\text{Dry matter fed to the pig} - \text{Fecal matter of the pig} )}{\text{Dry matter fed to the pig}} \times 100 \%[/tex]

where;

Dry matter fed to the pig = 2kg = 2000 g

Fecal matter of the pig = 200

The apparent digestible dry matter present = [tex]\dfrac{2000-200}{2000}\times 100\%[/tex]

[tex]=\dfrac{1800}{2000}\times 100\%[/tex]

= 90

Amount of Nitrogen(i.e. the protein) content present in the feedstuff = 2.41%

i.e.

2.41 g/100 g   OR   48.2 g/2000 g feed

Amount of protein present in feces = 4.6% (4.6 g/100 g  OR  9.2g/200g of feed)

apparent digestibility of the protein is:[tex]=\dfrac{\text{Amount in feed }- \text{Amount in feces}}{\text{Amount in feed }}\times 100[/tex]

[tex]= \dfrac{(48.2 - 9.2)}{48.2}\times 100[/tex]

[tex]= \dfrac{39}{48.2}\times 100[/tex]

= 81%

How can histograms help you describe a population? Use the word bank above to help you explain your answer.

Answers

Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

Explanation:

A histogram is a graphical representation of a variable using bars. In such a bar, its area is proportional to the frequency of the values represented. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest.  On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented.  Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).

Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.

The population can be given as the number of people living in a specific area. The histogram represents the population, with frequency as the function of the area.

What is a histogram?

A histogram is the graphical representation of the data in the form of bars. The population is given as the number of people in an area.

The population in the area is termed as frequency. The bar graph represents the frequency of population as the function of the area and thereby helps in the determination of the population.

Annotate the symbol by the reference image. Then, explain why this symbol represents an ion and how many electrons it has.

• the name of the element
• the charge
• the mass number
• the atomic number

Answers

Answer:

since the symbol has a "+1" sign at the top right corner it represents a positively charged ion.

it has 4 electrons as it has "+1" symbol meaning it lost one electron out of initially 5 electrons present.

name of element = Boronthe charge = +1the mass number = 11the atomic number = 5

Answer: ion has a 2+ charge then it must have lost electrons to form the cation. If the ion has 18 electrons and the atom lost 2 to form the ion, then the neutral atom contained 20 electrons. Since it was neutral, it must also have had 20 protons. Therefore the element is calcium.

Making Inferences Why do
you feel pain when you pull on
your hair or nails, but not when
you cut them?

Answers

Answer:

because the pain in our body is from the skin or tissue so when you pull the hair you are actually up rooting it from its attachment with ur skin hense you feel the pain

So your hair and nails are made of Keratin and don’t have nerves In them but they do have nerves attached to them. So pulling your nail or hair triggers the nerves around them and send signals to your brain to trigger pain. This is kinda similar to a spider web. The spider isn’t connected to the fibers in her web but she does feel the vibrations around her from the web. If you damaged a part of the web she wouldn’t be injured herself but she will be disabled because she essentially is missing a part of the system which she uses to survive. ( fun fact spider vision is actually very poor so their webs act as their eyes)

A reversible inhibitor that only affects multi substrate enzymes and binds to the enzyme only after one substrate has bound is a(n) ___

Answers

Answer:  

Uncompetitive inhibitor.

Explanation:  

Enzymes are the biological catalysts that catalyze the biological process and metabolic activity of the body. Without enzymes, all the biological activity becomes very slow. Enzyme provides suitable speed for the biological process. All enzymes are made up of protein. The uncompetitive inhibitor is the type of enzyme that only disturbs or affects multi-substrate enzymes and joins to enzymes only after one substrate has bound.

What is the relationship between the economy and environmental quality? (3 points)

Generally speaking, environmental quality initially declines and then improves as an economy grows.
Generally speaking, better economies are associated with better environmental quality.

Answers

Answer:

There is no relationship between the economy and environmental quality.

Environmental quality is a term related to different environmental cues such as, for example, air/water pollution, presence of noise, access to open public spaces, the visual impact of buildings, etc. Environmental quality can affect human health and the quality of life of the individuals in a given area/city. For example, water contamination is linked to the transmission of different diseases (e.g., gastroenteritis; encephalitis, hepatitis A), thereby negatively affecting human health and the quality of life of persons who don't have access to potable water. Similarly, poor air quality can be associated with respiratory diseases and cancer. The improvement in environmental quality does not necessarily involve economic resources. It is possible to improve environmental quality by:  

           1-protecting people against climate change;  

           2-improving water/air quality;  

           3-reducing pollution;  

           4-reducing waste and increasing recycling;  

5-limiting the visual impacts of new infrastructure; etc.

In conclusion, there is no direct association between the economy and environmental quality.
