Answe: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Explanation:
Answer:
Viruses replicate inside respiratory cells
Explanation:
The common cold is the most frequent disease that affects the human species and also the most frequent one seen by a Primary Care pediatrician. Since the number of infections is inversely related to age, despite its theoretical banality, it is a problem of the greatest quantitative importance, to which an important percentage of care time is devoted. Children are especially susceptible to this infection, due to the lack of development of immunity to most of the causative viruses, the less development of personal hygiene practices and the greater exposure to etiological agents. The cold is the most frequent diagnosis, both in Primary Care and in emergency services; although, its real frequency is masked by the usual use of synonyms (rhinoadenoiditis, rhinopharyngitis, high-altitude cold, upper respiratory infection) that disperse the diagnosis and may lead to the belief that these are different diseases. We prefer the term “common cold”, both because it is the translation of the most commonly used international nomenclature (“the common cold”), as well as being the name by which the population knows the disease, which has an importance beyond of semantics: most of our patients know very well that the cold has no curative treatment, but this is not the case if we make the diagnosis of “rhinopharyngitis” or “adenoiditis”. The impact of this disease on Public Health is incalculable at first visits, repeated unscheduled controls, truancy and work, and a huge economic impact, in the form of prescriptions, most of the time unnecessary, of antibiotics, cough suppressants, anti-thermics, mucolytics, nasal decongestants and antihistamines. On the other hand, the cold generates a routine of care responsible in good part of the demotivation and professional exhaustion of the pediatrician of AP ("burnout").
Others pinpoint 1637 as the true origin of Thanksgiving, owing to the fact Massachusetts colony governor John Winthrop declared a day of thanks-giving to celebrate colonial soldiers who had just slaughtered 700 Pequot men, women, and children in what is now Mystic, Connecticut.
The frequency at which the drug doses are administered is known as the dosage regimen. The dosage form refers to the physical form of a dose of the drug. The general dosage forms comprise capsules, tablets, ointments, patches, and aerosols.
The passage of administration refers to the manner in which the drug is administered. The general routes of administration include inhalation, oral, topical, and nasal.
In the given case, the patient needs 0.100 gm of a drug. The tablet is having 50 mg of the drug. Thus, the number of tablets needed for the prescribed dosage is:
0.100 gm * (1000 mg/1 gm) * (1 tablet/ 50 mg) = 2 tablets.
