Water bends light. This type of bending is called refraction. The drawing tool shows a penny submerged in water, but only part of the path of the light ray is shown. How could the light ray bend as it enters and leaves the water so that you can see the penny at position B? Draw the missing parts of the light ray so the penny is visible at position B.​

Water makes the penny visible by bending the light rays towards the normal.

Refraction is the bending of light rays as it crosses the boundary of media of different densities.

The ability of water to to bend light is employed in making a penny visible when water is added to container container a penny which was not visible initially.

Therefore, water makes the penny visible by bending the light rays towards the normal.

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?

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.
