Why in sudden outbreaks, it may be better to test for disease antigens rather than for antibodies?

2 answers:

4 0

Outbreak of diseases may cause by pathogens such as such as bacteria, viruses, fungi, and parasites. On the cell surface of these organisms proteins are present called antigens. On entering the antigen in the body, the immune system produce antibodies against antigen. It is better to test for disease antigens in sudden outbreaks because these antigens confirms the origin of the outbreak before the pathogen get destroyed by antibodies.

In the case, when the outbreak is sudden, there is a need to test for antigen, as the body has not generated any kind of antibodies yet to defend against the disease. It is thus better to test for the antigens.

In epidemiology, an outbreak refers to the sudden enhancement in the happenings of the disorder in a specific place and time. The outbreaks involve epidemics, which is usually applied for infectious diseases, as well as ailments with an environmental origin, like foodborne or water disease.

Question 2 (1 point) Question 2 Unsaved

Charra [1.4K]

Q2. The answer is C. Gymnosperms.

The word 'Gymnosperms' is derived from two greek words: 'gymnos' = naked and 'sperm' = seed. Literally, their seeds are naked, i.e. they do not form inside an additional structure. Their seeds develop on the surface of scales modified to form cones. This group of plants include pine trees, cycads, and cedar trees.

Q3. The answer is A. Angiosperms.

Angiosperms or flowering plants are seed-producing plants, just like Gymnosperms. Their seeds form inside additional structures known as fruits. This group is the most diverse group of plants and include nearly 300,000 species. Angiosperms include grasses, roses, maple trees, and many other plants with flowers.

Q4. The answer is B. Lichen.

Lichen consists of hyphae (just like other fungi) that surround cells of green algae or other photosynthetic organisms. This partnership between fungi and algae is known as mutualistic symbiosis. As in any other mutualistic symbiosis, both partners have benefits: fungi gain nutrients from algae and algae gain protection from fungi.


Q5. The answer is C. Vertebrate.

Vertebrates are organisms with an interior skeleton, or endoskeleton, and a backbone. Unlike vertebrates, invertebrates do not have a backbone or interior skeleton. The basic body plan of vertebrates includes vertebral column and/or notochord, the gastrointestinal tract below the notochord and the spinal cord above the notochord. Vertebrates include fish, amphibians, reptiles, birds, and mammals.


Q6. The answer is B. Invertebrate.

Invertebrates are organisms without an internal skeleton and backbone. The main difference between vertebrates and invertebrates is that vertebrates have backbone and internal skeleton and invertebrates lack in those structures. Invertebrates include all animals that are not vertebrates and include about 97% of all animals. Some of them are insects, sea anemones, and worms.

Q7. The answer is A. Bilateral Symmetry.

Bilateral symmetry is symmetry around a single line. That means that only one plane divides an organism into two matching halves, left and right. Thus, this type of symmetry is also known as left-right symmetry. Word 'bilateral' comes from two Latin words: 'bi-' means 'two' and 'latero' means 'side', literally 'bilateral' = 'two sides'. Human beings are the example of organisms with bilateral symmetry.

Q8. The answer is C. Asymmetry

Asymmetry means without symmetry. The word 'asymmetry' is derived from two Greek words: 'a-' = 'not' and 'symmetros' = symmetry, commensurable. Not all animals are symmetric. There are some species that show asymmetry, such as some sponges and flatfish.

Q9. The answer is B. Radial Symmetry.

A symmetry around any point is radial symmetry. The body of radially symmetric organisms can be divided into equal parts about a central point and they have no left or right side of the body. This type of symmetry is characteristic for sea stars, sea cucumbers, sea anemone, jellyfish, corals.
