Answers

Answer: evolution and natural selection

Explanation:

The process of change in a population over time is called evolution. The process by which organisms that are better adapted to the environment survive and reproduce is called natural selection.

What is Evolution and natural selection?

Evolution is any net directional change or any cumulative change in the characteristics of an organism or the complete populations over the time period of many generations. In other words, it involves descent with modification. Evolution explicitly includes the origin as well as the spread of different alleles, variants, trait values, or character states of organisms.

Natural selection is a mechanism of evolution. The organisms which are more adapted to their environmental condition are more likely to survive and pass on their genes that aided their success or are beneficial for their survival. This process causes species to change and diverge over time into different groups.

A practitioner order is written for a continuous infusion of insulin at 3 units/hr; the premixed solution is composed of 100 units of regular U-100 insulin in 100 mL normal saline. At which rate (mL/hr) should the infusion run?

Answers

Answer:

3ml/hr

Explanation:

Number of units = 3units

Units per milliter = 100 ml

Number of mililiters in an hour = "X"

Hence, Given that 100 ml of solution have 100 units, each ml has 1unit, (100/100)

Therefore, in order to get 3 units in one hour the equation would be

number of units = units per mililiter * number of mililiters in an hour

3 = 1 * X

X = 3 / 1 = 3ml/hr

Therefore, the final answer is 3ml/hr.

Insulin is the harmone that regulate the blood glucose level.  The rate of infusion of insulin should 3 ml/hr.

Given here,

Number of units = 3 units

Milliliter per Units  = 100 ml

Number of mililiters in an hour = [tex]x[/tex] = ?

So, 100 ml of solution have 100 units, it means each ml has 1 unit of Insulin.

To get 3 units per hour,

[tex]\rm number\ of\ units = units/ mL\times mL/ hr[/tex]

Put the values,

If you have a standard score of Z = -1.7, what percentage of the population has scores farther away from the population mean (in either direction) than you? 6. If you have a standard score of Z = -1.7, what percentage of the population has scores greater than you?

Answers

Answer:

1. 2.28%

2. 97.72%

3. 84.13%

4. 31.74%

5. 8.92%

6. 95.54%

Explanation:

1. A z score of 2 means has a proportion of the population of 0.9772 below

Therefore, the percentage of the the population that have an higher score = (1-0.9772)×100 = 2.28%

2. A z score of -2 means the percentage of the the population that have an higher score = (1-0.0228)×100 = 97.72%

3. A z score of 1 means the percentage of the the population that have a lesser score = (0.8413)×100 = 84.13%

4. A z score of 1 means the percentage of the the population that have a higher score = (1-0.8413)×100 = 15.87%

The population that have a lesser z score than -1 = 0.1587×100 = 15.87%

Therefore. the total percentage of the population that has scores farther away from the population mean in either direction = 2 × 15.87 = 31.74%

5. Where the z score = -1.7, we have;

The proportion lesser = 2×0.0446×100 = 8.92%

6. The percentage of the population that has a z score > -1.7 is presented as follows;

The proportion that have a z-score<-1.7 = 0.0446

Therefore, the proportion of the population that have a z-score more than -1.7 = 1 - 0.0446 = 0.9554

Hence the percentage of the population that has a higher z-score = 100×0.9554 = 95.54%.

Question:

Perfect pitch is the ability to identify musical notes correctly without hearing another note as a reference. The probability that a randomly chosen person has perfect pitch is 0.0005.

Required:

a. If 20 students at Julliard School of Music art tested, and 2 are found to have perfect pitch, would you conclude at the .01 level of significance that Julliard students are more likely than the general population to have perfect pitch?

b. Show that normality of the sample proportion p should not be assumed.

Answer:

See explanation below

Explanation:

Given:

Sample size, n = 20

Probability that a chosen person has perfect pitch = 0.0005

x

Level of significance = 0.01

a) Let's find the probability of 2 or more people with perfect pitch using bimonial distribution.

P(2 or more with perfect pitch ) =

P(x≥2) = 1 - P(x≤1)

P(x≥2 | n=20, p'=0.0005) = 0.00005

Since the probability of getting 2 or more people with perfect pitch, 0.00005, is significantly lower than the level of significance, 0.01, we conclude that Julliard students are more likely than the general population to have perfect pitch.

b) For normality to be assumed,  [tex] n * \pi _0 [/tex] should be ≥5 for normal approximation.

Since [tex] n * \pi _0 [/tex] is too small, normality cannot be assumed.

A physician orders Lanoxin elixir qd for an 81-pound child based on 3.4 mcg/ kg/day. Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL. What volume should be administered per dose?

Answers

Answer:

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily

Explanation:

The child weighs 81 pound. The weight of the child is needed to be converted from pound to kg.

1 kg= 2.2 pound

Therefore 81 pound = 81/2.2 kg = 36.8 kg

Since the child is to be administered bases on 3.4 mcg/ kg/day, the volume of Lanoxin elixir qd to be administered to the 81 pound (36.8 kg) in one day = 36.8 kg × 3.4 mcg/ kg/day = 125.12 ≅ 125 mcg

Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL, therefore 125 mcg = 125 mcg / 50 mcg/ml = 2.5 ml

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily

Give a reasoned ethical advice to the company showing clearly the Ethical basis of your advice the challenges you envisaged and how to deal with the identified challenges.​

Answers

Answer:

   

When there is an Ethical issue, there is no substitute for doing the right thing. To try avoiding potentially undesirous consequences as a result of doing correcting one's mistakes is more damaging in the long run.

First, it starts internally. When employee of such company find out that the management and stakeholders have compromised on the standards of the ethics of integrity, it creates an excuse for them to do likewise and may even become too difficult to manage as it may become a source of blackmail in the short or long run.

My advice to the company is to quickly put out a campaign against the drug which is killing people.

The primary reason why the company is in business in the first place is to save lives by creating drugs that help to do so. To keep quiet in the face of this mistake is to go against everything it stands for.

Yes, it is possible for legal charges to follow. However, as a multinational, it is expected that they have anticipated and made some preparations for this by way of instituting Insurances such as product liability and or errors and omissions which help to reduce the liability of the company in the event of this kind of issues as well as provide monies for compensating the affected individuals and families.

The company will, of course, have to notify it's insurers immediately.

History shows that a public apology has been shown to work in similar circumstances and can help to douse (though not eliminate completely) the onslaught against its reputation that would follow when it makes the announcement.

Legally, when an issue of tort such as this arises, the best bet is for the company to quickly settle out of court if possible.

Explain the contribution of cholinergic system in controlling different levels of activities

Answers

Answer: Respiration is altered during different stages of the sleep-wake cycle. We review the contribution of cholinergic systems to this alteration, with particular reference to the role of muscarinic acetylcholine receptors (MAchRs) during rapid eye movement (REM) sleep. Available evidence demonstrates that MAchRs have potent excitatory effects on medullary respiratory neurones and respiratory motoneurones, and are likely to contribute to changes in central chemosensitive drive to the respiratory control system. These effects are likely to be most prominent during REM sleep, when cholinergic brainstem neurones show peak activity levels. It is possible that MAchR dysfunction is involved in sleep-disordered breathing, such as obstructive sleep apnea.

Cytokine production is necessary to protect against pathogens and promote tissue repair, but excessive cytokine release can lead to systemic inflammation, organ failure and death. Inflammatory responses are finely regulated to effectively guard from noxious stimuli. The central nervous system interacts dynamically with the immune system to modulate inflammation through humoral and neural pathways. The effect of glucocorticoids and other humoral mediators on inflammatory responses has been studied extensively in the past decades. In contrast, neural control of inflammation has only been recently described. We summarize autonomic regulation of local and systemic inflammation through the ‘cholinergic anti-inflammatory pathway’, a mechanism consisting of the vagus nerve and its major neurotransmitter, acetylcholine, a process dependent on the nicotinic acetylcholine receptor α7 subunit. We recapitulate additional sources of acetylcholine and their contribution to the inflammatory response, as well as acetylcholine regulation by acetylcholinesterase as a means to attenuate inflammation. We discuss potential therapeutic applications to treat diseases characterized by acute or chronic inflammation, including autoimmune diseases, and propose future research directions.

Conduct an appropriate hypothesis test to answer this question using a 0.05 significance level. Provide the hypotheses, test statistic(s), p-value(s), and a formal conclusion. (Hint: Use Chi-Square test).

Answers

Answer:

Compare your info

Explanation:

Read everything carefully and compare your info and data to find the best solution.

Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. There is insufficient evidence to conclude that there is an association between music in utero and time of advancement to crawling/walking in infants.

What is hypothesis?

A hypothesis is an explanation proposed for a phenomenon. The scientific method requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.

Advancement to Crawling/Walking Music In Utero Early On Time Late

Mozart(Piano Sonata) 32 19 12

Philip Glass (minimalist music) 24 23 13

White Noise and Silence 8 9 27

To test for association between music in utero and time of advancement to crawling/walking in infants, we can use a chi-square test of independence.

The null hypothesis is that there is no association between the two variables, and the alternative hypothesis is that there is an association.

The test statistic is calculated as follows:

χ² = Σ (Oij - Eij)² / Eij

where Oij is the observed frequency in cell (i,j) and Eij is the expected frequency in cell (i,j) under the null hypothesis.

The expected frequencies can be calculated by multiplying the row and column totals and dividing by the grand total.

The degrees of freedom for the test are calculated as (r - 1) x (c - 1), where r is the number of rows and c is the number of columns.

Using a significance level of 0.05, the critical value for the chi-square test with 4 degrees of freedom is 9.488.

The calculations for the test statistic and p-value are shown below:

χ² = (32-25.81)² / 25.81 + (19-20.18)² / 20.18 + (12-16.01)² / 16.01 + (24-24.24)² / 24.24 + (23-21.68)² / 21.68 + (13-14.08)² / 14.08 + (8-12.18)² / 12.18 + (9-9.08)² / 9.08 + (27-22.73)² / 22.73 = 4.191

The degrees of freedom are (3-1) x (3-1) = 4.

Using a chi-square distribution table or calculator, we find that the p-value for the test is 0.241.

Thus, as we cannot reject the null hypothesis because the p-value is greater than the significance level of 0.05. There is insufficient evidence to conclude that there is a link between music in utero and the age at which infants begin crawling/walking.
