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%.

a) postganglionic synapses.
b) visceral reflex responses.
c) motor neurons.
d) ganglionic neurons.
e) afferent neurons.
Within the autonomic nervous system, preganglionic fibers leave the CNS and then synapse on postganglionic synapses. Thus, the correct option is A.
What is the Autonomic nervous system?The autonomic nervous system may be characterized as a command system that performs largely unconsciously and controls bodily operations, such as the heart rate, digestion, respiration, etc.
The autonomic nervous system regulates the function by operating the information at the preganglionic fibers which then leave the central nervous system of the body and then synapse on the postganglionic synapses of the peripheral nervous system.
Therefore, within the autonomic nervous system, preganglionic fibers leave the CNS and then synapse on postganglionic synapses. Thus, the correct option is A.

A certain type of ship has two tanks in its engine. Each tank contains a different type of fuel. When the engine turns on, the same amount of energy is transferred out of both fuels why did fuel 1 change phase, but fuel 2 stayed the same? Explain what happened to the molecules of both fuels
Answer:
Fuel 1 changed phase because the energy drawn from it dropped its temperature below the transitional temperature that causes a phase change, fuel 2 still has its temperature well above the transitional temperature required to change phase.
Explanation:
For a substance to change phase, a transitional temperature has to be reached. This is because, the temperature of substances generally indicates the average kinetic energy of its molecules. An increase in energy input to the system will result in a change to a more mobile phase like from solid to a liquid state or from a liquid state to a gaseous state state, while taking energy from the system will cause a transition to a less mobile phase like gas to liquid or liquid to solid state.
It can be deduced that Fuel 1 changed phase due to the fact that the energy drawn from it dropped its temperature below the transitional temperature which caused a phase change.
On the other hand, fuel 2 has its temperature above the transitional temperature that is required to change phase.
It should be noted that for a substance to change phase, then a transitional temperature has to be reached. This is due to the fact that the temperature of substances indicates the average kinetic energy of their molecules.

The table below relates to a study where infants listened to three types of ‘music’ in utero and their advancement to crawling/walking was then observed and categorized as either early, on time, or late. The goal of the study was to determine if there was a statistically significant association between music in utero and time of advancement to crawling/walking in infants. Advancement to Crawling/Walking Row Sample Sizes Music In Utero Early On Time Late N Mozart(Piano Sonata) 50.8% 30.2% 19.0% 63 Philip Glass (minimalist music) 40.0% 38.3% 21.7% 60 White Noiseand Silence 17.9% 21.1% 61.0% 44 The table above provides row percentages and sample sizes. For example, 50.8% of ‘Mozart’ infants have ‘Early’ advancement to crawling/walking and there are 63 total ‘Mozart’ infants. a.Based upon the row percentages provided, fill in the contingency table below with the approximate cell counts, rounding to the nearest whole number. Advancement to Crawling/Walking Music In Utero Early On Time Late Mozart(Piano Sonata) Philip Glass (minimalist music) White Noiseand Silence Do the data indicate an association between music in utero and time of advancement to crawling/walking in infants? 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).
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.

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?
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
Fill in the blanks with the correct word or phrase. The process of change in a population over time is called . The process by which organisms that are better adapted to the environment survive and reproduce is called .
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.
