Answer:
location
, events
Explanation:
A three dimensional universe is comprised of three measurements, width, breadth, and height.
In a three-dimensional universe, the position of a spacecraft is defined by its location. In a four-dimensional system, the spacecraft defines a line that represents events through which the object passes.
TLDR: Antibiotics must be taken several weeks to fully kill the bacteria. Else, surviving bacteria develops drug resistance.
Antibiotic prescription really depends on the patient's condition. Some conditions like major surgery or diseases that cause immunosuppression are more prone to bacterial infection, thus they must take antibiotics for prolonged periods of time to fight their current infections or prevent further infections.
Antibiotics, as a general rule, must be given 7 days or several weeks (depending on the bacteria/pathogen) to be sure that all the disease-causing bacteria are dead. If the drugs are taken only until symptoms fade, the surviving bacteria (now fewer in number and not causing symptoms) will develop mutations that may help resist the previously-taken antibiotic, giving rise to drug resistance.
Thus, Arjun must take the antibiotics for several weeks more (according to the doctor's orders, of course) to kill all remaining bacteria and also to prevent bacterial drug resistance. Which is really problematic, since we're slowly losing our number of effective antibiotics.
Answer:
The correct answer is option - A.
Explanation:
Hormones their target sites are other endocrine glands and act on these endocrine glands, known as tropic hormones. The pituitary gland is one of the gland that acts as a gland that releases tropic hormones and also regulated by the other tropic hormones released by the hypothalamus.
The hypothalamus releases several tropic hormones that inhibit and promoting hormones that regulate the pituitary glands.
Thus, the correct answer is option - A.
The correct answer is D) An apparently longer survival time among persons identified during a screening program because they were identified at an earlier stage of their disease
Explanation:
In medicine, screening is a method to diagnose diseases even if the person has no symptoms; due to this, screening is related to earlier detection of diseases than traditional diagnosis based on symptoms. Early diagnosis does not imply longer survival time, but it can lead to doctors or individuals to perceive the survival time was longer, this phenomenon is known as lead-time bias.
For example, a person diagnosed with cancer at an early stage when he is 45 years old, dies at 50 years old, this means his survival time was 5 years. If the same person is diagnosed at 48 years based on symptoms and he dies at 50 it seems the survival time is less (2 years); however, this is biased as the diagnosis did not change the effect of the disease. According to this, lead-time bias can be described as "an apparently longer survival time among persons identified during a screening program because they were identified at an earlier stage of their disease".
Answer: B. Pathogens.
Explanation: The word pathogens refers to external agents that are hosted in live organisms (humans, animals or vegetals), and has the property of affecting the host causing diseases or damages visible or not. Saying this, the microorganisms described in the question are pathogens.
Option A. Incorrect. Tumors are described as an abnormal growth of any group of cells of an organism.
Option C. Incorrect. Interferon is a protein released by cells of the immune system when it is time to defend the body against microorganisms.
Option D. Incorrect. Immunoglobulins are proteins created specifically for attacking an antigen (something harmful for the body). They are also part of the immune system.
