Answer:
D. Single-stranded
Explanation:
DNA normally has a <em>double-stranded </em>structure. Each strand is composed by nitrogenous bases, sugars and phospates; strongly binded together by chemical bonds. The strands are bonded to each other, however, by relatively <em>weak interactions </em>between the hydrogen atoms in the nitrogenous bases in each strand. The energy supplied by heat is enough to break the weak interactions between hydrogens, but not enough to break the strong chemical bonds that make up the strands.
The correct answer is delirium.
The Confusion Assessment Method (CAM) is a psychiatric tool used to assess and identify delirium in patients. According to the first observations and the patient's responses to CAM, the nurse can conclude that the patient exhibits signs of delirium. This is because he is unable to concentrate and organize his thinking, he is inattentive, he is lethargic and all these behaviours are sudden and acute. These symptoms cannot be associated with dementia, as dementia develops gradually and doesn't affect attention and consciousness. Also, the symptoms don't point to depression since depressive patients are focused and attentive. Finally, the nurse cannot conclude that the patient is dehydrated because further tests need to be conducted to assess hydration.
Yes ma’am or sir here take a look
The answer is hypernatremia. Common early symptoms attributed to this condition include a strong feeling of thirst, weakness, nausea, and loss of appetite. Normal serum sodium levels should range between 135 – 145 mmol/L. Hyperaldosteronism (increased production of aldosterone) may be the underlying cause of the condition.
