Kathy Morningside is a 55-year-old woman who has had spells of gastroin- testinal problems over the years (dyspepsia), but a formal diagnosis has never been conclusive. During the past four months, she has had a history of vomiting after some meals and she has lost about 5 kg over this time. Mrs Morningside, together with an old school chum, went to London for a weekend theatre break to see Les Miserables. On the Friday evening, she began to feel unwell, but put it down to her fear of flying. They went to the theatre on the Saturday evening and followed this with a light opera supper at a nearby restaurant. Mrs Morningside suffered a haematemesis and was rushed to hospital with massive bleeding. Her condition settled and follow- ing overnight rehydration, she returned to her home in Newcastle where she was examined by a gastrointestinal consultant. The consultant noted that Mrs Morningside was pale and tachycardic. Her blood pressure was 130/90 mmHg. Rectal examination revealed frank melaena. He attributed the bleed to chronic peptic ulceration, probably as a consequence of long-term use of non-specific anti-inflammatory drugs. He considers her to be at high risk of re-bleeding and may contemplate partial gastrectomy when her nutritional intake has improved. The consultant refers Mrs Morningside to the dietitian as he is concerned about her overall nutritional status. She is currently anaemic (frank iron and possibly megaloblastic/pernicious anaemia). (1) Explain the approaches that may be taken to assess this patient's nutri- tional and dietary status. (2) Consider the dietary assessment more carefully. What may be the prin- cipal focus of the interview with the client? What advance preparation might assist you in the conduct of the assessment interview?
In order to assess the nutritional status of the patient, the nurse needs to understand the anthropometric measurements of the patient by:
The physical examination helps to understand the physical appearance of the patient and to find out the BMI.Monitoring the intake and output chart helps to understand the nutritional status of the patient.Monitoring the weight helps to understand the accurate weight loss of the patient.How to depict the information?The patient is having chronic peptic ulceration so, the focus of the dieticians during the interview must be the collection of history about the previous intake of the anti-inflammatory medications.
In order to confirm it, the dietician needs to ask the patient about the past medical condition and treatments.
As an advance preparation, the dieticians need to study the case sheets of the patient to get an idea about the patient prior to the interview session.
The principal focus of the interview with the client will be the food that the client normally eats and previous treatment regarding the illness.
The advance preparation that might assist in the conduct of the assessment interview is to read extensively on the disease in order to have more information about it.

Based on the structure of proteins, how would you explain why Beau’s coat hair changed from straight to curly? Be your explanation describes what is happening at the molecular level to proteins
Beau’s coat hair changed from straight to curly because of Denaturation occurs.
What is happening at the molecular level to proteins?When a chemical relaxer and heat are applied to curly hair, the protein present inside your hair gets denatured. Due to this denaturation of protein in the hair, the hair is soft and flexible which can be converted into any direction and different styles can be done. If a chemical perm or relaxer is applied to straight hairs, it also denatures the protein and make the hair curly.
Thus, Denaturation occurs.

the 5’ end of the dna molecule is considered ____, while the 3’ end of the dna molecule is considered the _____
The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.
Thus, The backbones of DNA's two long polymers of basic units, known as nucleotides, are comprised of sugars and phosphate groups that are connected by ester bonds.
These two strands are anti-parallel because they move in the opposite directions of one another. Each sugar has one of four different nucleobases (bases) molecules attached to it.
The genetic code is made up of the order of these bases, and it subsequently dictates the order of the amino acids in proteins. The 5′ (five prime) and 3′ (three prime) ends of DNA strands are referred to as the ends.
Thus, The 5’ end of the dna molecule is considered five prime, while the 3’ end of the dna molecule is considered the three prime.

The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows
Species A: CAGGCCATTATG
Species B: CCAGCCTATAGG
Based on this information, which of the following best explains the difference in the DNA sequence between the two species?
A) Species A and B probably share the most recent ancestor because they only differ by three mutations.
B) Species A and B have fewer differences between DNA sequences means that fewer mutations occurred.
C) Species A and B probably have distinct ancestors because they have many differences in mutations.
D) Species A and B are closely related because they differ by five mutations in their DNA sequence.
It is expected that Species A and B have distinct ancestors because they have many differences in mutations (Option C).
What is the mutation rate?The mutation rate makes reference to the number of mutations that appeared in a given nucleotide sequence in a given period of time.
In this case, sequences from Species A and B have 5 mutations and aligned sequences have only 12 nucleotides, which is a considerably high mutation rate to share a common origin.
Nonetheless, information about divergence times might be helpful to determine the origin of these sequences.
In conclusion, nucleotide sequences of Species A and B exhibit many mutations and therefore they do not have the same evolutionary origin (Option C).

Based on the reactivity of catalase in the enzyme concentration lab, do your results in testing enzyme concentration support your hypothesis?
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
What is an enzyme?The enzymes are the chemical molecules that alter the chemical reaction when added in a specific amount, it either increases the reaction, or decrease it.
There were more substrate molecules to bond with the active site of the catalase enzyme as the substrate concentration increased.
Because the substrate concentration increased each time, there was a greater chance that the substrate would bind to the active site and carry out the reaction.
Thus, this way the enzyme concentration affects the reactivity.

Describe artificial selection, and explain how it is different from natural selection.
Answer:
Starting with natural selection, the most robust and most intelligent animals survive over the weakest. The weak animals eventually die off because they can't keep up with nature. Artificial selection isn't natural; certain species are being targeted on purpose and decide whether to stay alive or not. At this point, it is not at all about whether the species can survive or not because it's most likely being protected.

The pH value is a unit of measure which describes the degree of acidity or alkalinity of an aqueous solution. In other words, pH demonstrates the quantitative information of the activity of an acid or base based on hydrogen ion concentration.
The mathematically formal definition of pH is the negative logarithm of hydrogen ion concentration:

Hence, if the concentration of [tex]\text{H}^{+}[/tex] ions in a solution is [tex]1.0 \ \times \ {10}^{-7} \ \text{M}[/tex],
[tex]pH \ = \ -\log_{10}\displaystyle{\left(1 \ \times \ {10}^{-7}\right)} \\ \\ pH \ = \ -\log_{10}\displaystyle{\left(1\right) \ - \ \log_{10}\left({10}^{-7}\right)} \\ \\ pH \ = \ 0 \ - \ \left(-7\right) \\ \\ pH \ = \ 7[/tex].
