The elephants represented in lanes 3 and 5 could have been a match to the ivory sample if you failed to amplify one allele in ei

ther the ivory or the sample, so you cannot exclude these choices without running the experiment multiple times. On the other hand, you can definitely eliminate the elephants in lanes 1, 2, 4, and 6. Explain why.

About the question:

I failed to find the result of the PCR / electrophoresis. However, I will try to explain when to still consider a sample, and when to exclude it.

Answer:

Probably elephants 1, 2, 4, and 6 exposed a pattern of lines that differed in most alleles from the ivory´s pattern. So they were considered to be different and, hence, excluded. However, elephants 3 and 5 only were different in one allele, which might be due to the amplification failure. In these last situations, the experiment must be run again, and include many markers.

Explanation:

The genetic profile is the series of alleles, characteristic of each individual, concerning a series of DNA fragments.

Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it.

In the exposed example, probably we have a profile of the ivory sample, and we need to find out to what individual or population it belongs to. So we need to compare the pattern of bands of the different lanes with the ivory´s pattern of bands.

In resumed terms, if the ivory´s patterns completely match with another lane pattern, then this is the individuals or population to whom it belongs the ivory. However, if they do not match, we need to exclude this individual.

But this is not as easy as it looks like. Sometimes it is difficult to interpret the results because bands are not so clear, and sometimes there are failures during amplification, as said before in the statement of the problem.

In these situations, what you need to do is look for the lanes that match the most with the ivory one and discard those that differ the most. These last patterns probably belong to a different animal or population, that why they can be excluded. Individuals suspected of being the same as the individual understudy or belonging to the same population, must be subducted to a repetition of the study. Also, the use of several markers in the study increases the matches chances.

So, in the exposed example, if the amplification fails in one allele, elephants 3 and 5 could be a match to the ivory sample, probably because all the other alleles do match. You can only exclude them if, after the experiment repetition, the involved allele is still different. On the other hand, you can eliminate the elephants 1, 2, 4, and 6 because their pattern bands are significantly different from the ivory´s patterns, so you do not even need to repeat the experiment.

Glycoproteins are molecules that are partially simple _______ and partially _________. fig 4.27
serg [7]
The correct answers are "sugar" and "amino acids." We can find this answer within the name itself. The prefix "glyco-" relates to producing sugar (think glucose and glycogen, which are both forms of sugar), and the suffix "proteins" is exactly that: proteins (which are made up of amino acids). So, when we say glycoprotein, we can think "sugar-protein," which gives us our answer.

When emphysema is a result of a α1-Antitrypsin disorder, assessment data is likely to include which of the following?
Aloiza [94]

Answer:

a. Caucasian Client age younger than 50

Explanation:

<u>α-1 Antitrypsin:</u> In biology, the term "α-1 Antitrypsin" is also referred as "A1AT" and is determined as a serpin that consists of a major "protective effects" against the cigarette smoking and involves the development of emphysema, along with that the patients with the mutations of the "A1AT gene" tends to display an increased risk of emphysema development. However, It is mostly developed in people who are younger in age ranging from 30 to 40 years.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

The particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly.
dimaraw [331]

The change in motion affect the temperature of the system as the temperature of the system is lower now than it was initially. Faster moving particles result in a higher temperature for the system.

<h3>What is temperature?</h3>

It should be noted that temperature simply means the degree of hotness or coldness of a body.

In this case, the change in motion affect the temperature of the system as the temperature of the system is lower now than it was initially

Also, it should be noted that faster moving particles result in a higher temperature for the system.

#SPJ4

The particles in some system are moving around quickly. A few minutes later, the particles are moving, on average, more slowly. How does this change in motion affect the temperature of the system? A. The temperature of the system did not change. The speed of the particles has no effect on the temperature, only the type of atom affects the temperature. B. The temperature of the system is higher now than it was initially. Slower moving particles result in a higher temperature for the system. C. The temperature of the system did not change. The speed of the particles does not affect temperature, the number of particles affects the temperature. D. The temperature of the system is lower now than it was initially. Faster moving particles result in a higher temperature for the system.
