The most appropriate nursing action is to WORK WITH THE NUTRITION STAFF TO PROVIDE NUTRITIOUS MEALS AT OFF HOURS. 
The nurse should respect the decision of the patient about the fasting. When the patient break his fast, the nurse should ensure that the patient eat balanced and nutritious meals.

People who are tune deaf are unable to follow a rhythm. Scientists have evidence that tune deafness can be genetic. The pedigree
butalik [34]

Question

Pedigree attached

a. Provide evidence from the pedigree that conclusively shows that the tune deafness allele is autosomal dominant, not autosomal recessive. Explain your reasoning.

b. Identify the genotypes of individuals 5 and 6, and then draw the Punnett square for the cross of these two individuals.

c. Compare the expected percentage of each phenotype of the offspring from the cross in part (b) with the actual percentage of each phenotype observed in the children of individuals 5 and 6.

Answer/Explanation:

a. Autosomal dominant means that even having one copy of the allele T will produce a tune deaf individual. The evidence of this is that individuals II.3 and 4 have children (III. 8 and 9) with normal tune perception. This suggests that they have inherited the normal allele from both parents. That means II.3 and II4 must be heterozygous, in order to pass on the normal allele. This makes sense if tune deafness is dominant (because 3 and 4 will both be Tt and Tt, so can pass on the t alleles). However, if tune deafness was recessive, that would mean that individual II 3 and 4 both have to carry 2 copies, meaning there is no way their children would have normal tune perception.

b. Since individual 5 is unaffected and we know this is the recessive trait, they must be Tt. Since individual 6 is affected, they must be either Tt or tt. However, they have children who are unaffected (11, 12, 13) who must be tt. This means, individual 6 must have the t allele to pass on, and must be Tt. Therefore, the cross between individuals 5 and 6 is tt x Tt:

         T        t

t        Tt       tt

t       Tt       tt

c) The punnet square shows the children from (b) have a 50:50 chance of being tune deaf vs normal tune perception (50% each). In contrast, the actual ratios are 25% tune deaf to 75% normal tune perception. (1:4). This deviates from the expected ratio, but since all of these are due to chance, it is not an unexpected occurrence. Perhaps if there were 10, 50 or 100 children (!) from this cross, the results would be more like the expected ratio

How does global warming affect the water cycle
Gennadij [26K]

Answer:

Climate change is likely hastening aspects of the water cycle as rising global temperatures raise the rate of evaporation globally. On average, higher evaporation leads to more precipitation. According to certain climate projections, coastal regions would get wetter while the center of continents will become drier.

Explanation:

There's many affects: three main ones are evaporation, precipitation, and surface runoff and stream flow.

You can see negative affects on Oceans, snowpack, clouds, and changes in water demand too.

Evaporation

Warmer air has the ability to store more moisture than chilly air. When a result, as the earth warms, the air will absorb more water from the seas, lakes, soil, and plants. The drier conditions left behind by this air might have a significant impact on drinking water supplies and agriculture.

On the other hand, the warmer, wetter air may imperil human life. Greater humidity, according to a research from Columbia University's Lamont-Doherty Earth Observatory, would make future higher temperatures unpleasant in certain regions by preventing the cooling benefits of our perspiration.

Precipitation

When all of that extra warm, more moist air cools, it pours more rain or snow on the earth. As a result, a warmer earth brings more rain and snowstorms. So far, the northeastern United States has seen the greatest rise in the severity and frequency of heavy precipitation events. Since 1979, thunderstorm groups in the Central United States have been more common and have dropped more precipitation.

Climate change will alter where precipitation falls by changing air temperatures and circulation patterns. Some regions, including the American West, Southwest, and Southeast, are anticipated to become drier. Meanwhile, the northern United States and the Midwest are forecast to receive more rain. These precipitation forecasts are already coming true.

According to the National Climate Assessment, the Southwest, southern Great Plains, and Southeast will see more intense and persistent droughts. And the majority of the rest of the country is also at danger of more severe short-term droughts. Researchers at the Earth Institute discovered that climate change may have already increased historical and current droughts, and that drier circumstances are exacerbating wildfires.

Changes in precipitation patterns will put many farmers, as well as natural ecosystems, in jeopardy. Columbia University's International Research Institute for Climate and Society scientists are developing tools and techniques to assist farmers in adapting to these difficulties. Natural ecosystems, on the other hand, may be unable to adapt as rapidly.

Surface Runoff and Stream Flow

Flooding can occur as a result of larger bursts of precipitation generated by warmer, wetter air, which can risk human lives, destroy houses, ruin crops, and harm the economy. Surface runoff — the water that pours over the ground after a storm — will also rise with heavier rainstorms. This rushing water may remove nutrients from the soil as well as sweep up pollutants, dirt, and other unwanteds, draining them into neighboring bodies of water. These toxins may contaminate our water sources and increase the cost of cleaning the water to meet drinking standards.

Furthermore, when runoff deposits sediments and other toxins into lakes and streams, it may endanger fish and other species. Fertilizer runoff may trigger algal blooms, which can suffocate aquatic species and create a nasty mess. The problem is exacerbated by warmer water, which can't store as much dissolved oxygen as fish require to thrive. These circumstances might impair fisheries and make it unpleasant for those who like fishing, swimming, and other recreational activities in lakes and streams.
