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%

Which statement describes Mendel’s hypotheses regarding gametes?
A) gamete carries two genes for a trait.
B) gamete carries one allele for a gene.
C) gamete can carry multiple alleles for a trait.
D) Some gametes are dominant and some are recessive.

Answers

Answer:

The correct answer is B. A gamete carries one allele for a gene.

Explanation:

Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.

According to the Law of segregation given by Gregor Mendel-

During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.

Thus, option B) is the right answer.

From what you know of tonicity, what can you say about the plant cells and the solutions in the test tubes

Answers

Answer:

Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion.

Explanation:

Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion. There are three types of tonicity i.e. hypertonic, hypotonic and isotonic solution. If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink due to more solute in the external environment. In an isotonic environment, there is no water movement occurs, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. due to lower amount of water present inside the cell.

Succulents and cacti often have short, thick leaves with a waxy coat. What function does this structure serve?

A) retains water

B) the plant uses less energy to grow these short leaves and conserves energy

C) prevents water from evaporating off leaves

D)all of the above

Answers

Answer:

C) prevents water from evaporating off leaves

Explanation:

Succulents and cacti are a group of plants known as XEROPHYTES. These are plants that grow and survive in areas or conditions where there is lack of water e.g deserts.

However, these plants need to adapt to the low or no water condition and one of the ways they do this is by possessing short, thick leaves with a waxy coat. This enables them to preserve water that would have been lost via transpiration from the leaves.

Answer:

(c) prevent water from evaporating off leaves

what are the three strategies that the community could place to work with governmental structures to stop illegal dumping​

Answers

Answer:

Illegal Dumping has gotten out of hand.  According to the Los Angeles County Public Works, “People usually dump illegally to avoid collection and disposal fees, or because they believe proper disposal is just ‘too much trouble’.”   This is very unfortunate for our communities who receive the negative consequences of higher taxes for cleanup, environmental hazards, and a breeding ground for rats.

The cost of a one-time cleanup and detoxing of an area can cost thousands of dollars.  But to leave the mess is just not an option.  The best option is to stop the illegal dumping before it happens, preventing the cost of cleanup, preventing the chemicals and toxins from entering the ground water, and preventing the rats and mosquitoes from breeding.  The best areas to live are communities that care about their community!  So, what can a community do to prevent illegal dumping?

Here are some key points to help deter illegal dumping:

Educate the public through the schools and through community awareness groups about the costs, chemical hazards and dangers incurred by illegal dumping

Create safe, public-friendly waste disposal options and advertise them

Create laws that impose stiff fines for the perpetrators and advertise these stiff fines

Use Illegal Dumping Cameras to catch the perpetrators in the act

Use Social Media to ask the public to identify the perpetrators

Follow through with quick clean up

These steps will invite the citizens to be involved and help deter the criminal activity of illegal dumping within your community.

Explanation:

When performing the streak for isolation technique, your result is unexpected: There is only growth obtained in quadrant 1. The growth observed in quadrant 1 is as expected, heavy with no isolated colonies. However, no growth is visible in any other quadrants.
Which of the following errors could explain this unexpected result?
A) The loop did not cross into quadrant 1 when streaking quadrant 2
B) You forgot to flame the loop in between quadrants
C) All of the errors listed here could be responsible for this unexpected result
D) Not enough bacteria was obtained from the starting culture when streaking quadrant 1

Answers

Answer:

A) The loop did not cross into quadrant 1 when streaking quadrant 2

Explanation:

The streak for isolation technique is a method used to get isolated bacterial colonies. This technique consists of, in a petri dish with culture medium, where, with the help of an inoculation loop, the bacteria are scratched on one side of the dish. This side is called the first quadrant. This inoculation loop must then cross with the first quadrant and be dragged to the second quadrant, where new lines must be made. This allows a part of the bacteria from the first quadrant to be carried over to the second. The inoculation loop must cross the second quadrant again to inoculate the third quadrant, and so on.

In this case, we can see that for bacterial colonies to grow in all quadrants, it is essential that the loop crosses in the first quadrant to cross out the second quadrant. If not, only the first quadrant will have bacterial colonies.

Answer:

A) The loop did not cross into quadrant 1 when streaking quadrant 2

Explanation:

There are many different techniques to isolate bacteria populations. Using solid media such as agar, you can perform the streak for isolation technique.

What you want to do by using this technique is to get an isolated colony of the bacteria of interest. And to get it, you need to dilute a sample or inoculum of bacteria as much as possible by streaking it. Every time you do it, you take fewer amounts of cells from the original sample, separating them each time more, to the point of having only one single cell apart by a few millimeters from another cell. The isolated cell divides and forms a new pure colony.

So basically, you need to imaginary divide the agar plate into four quadrants.

You sterilize the loop carefully and take a sample of bacteria, trying to get the smallest amount of inoculum. You will apply the loop with the sample in quadrant one and spread it. You close the plate and turn it, placing the second quadrant in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant two but carefully touching the edge of quadrant one, so you can take some of the cells that you have already spread on it. Once you spread quadrant two, you close the plate and turn it again, so quadrant three is in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant three but carefully touching the edge of quadrant two. Close and rotate the plate. You sterilize the loop and repeat the same motion in the last quadrant. Close the plate and take it to incubation. Finally, you put the loop on the flame for the last time.The importance of extending the streaks into the anterior quadrant is to take a few cells from there and to spread them in the following quadrant. In this way, you are diluting the original inoculum, and separating the cells each time more. The fourth quadrant should have a few isolated cells that will reproduce and form a pure colony. If you do not touch the anterior quadrant while streaking, you will not have any cell in the quadrant, and you will not observe any colony after the incubation. The importance of sterilizing the loop every time you change the quadrant is to avoid contamination with other species. If you do not flame the loop, the result will be too many colonies of different species, probably touching themselves, in each quadrant.
