B. That all organisms are related to one another
Answer:
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.
Explanation:
Answer:E. Down-regulation
Explanation:Cells typically up or down regulate depending on the concentration of a hormone levels. When there is a excessive concentration of a hormone in the blood stream, the cell decreases the number of receptors reducing the interaction with that hormone, Also, when there is excessive hormone reduction, the target cells activate to increase their number of receptors.
Down regulation occurs by the the deactivating or degrading of target cells to reduce the number of receptors due to their sensitivity to a particular excess hormone.
Answer:
Syphilis is a sexually transmitted disease
Explanation:
Syphilis is a sexually transmitted infection caused by <em>Treponema pallidum</em>, a spirochaete gram-negative bacterium with various subspecies. This disease is transmitted through direct contact (person to person) by different types of sexual acts. A chancre is an infectious genital lesion that is considered to be the first stage (and symptom) of syphilis. The incubation period of syphilis is 14-21 days. Syphilis can be divided into four stages: primary, secondary, latent, and tertiary. Primary syphilis produces chancres on the genitals, mouth, rectum, etc. Secondary syphilis causes rashes that occur from 2-8 weeks after the chancres. The third (latent) stage is a latent/hidden phase without noticeable symptoms. Finally, the tertiary (late) stage causes large sores within the body that affects the heart, nervous system, etc. The best manner to prevent syphilis is by practicing safe sex (e.g., by using condoms). It has been suggested that syphilis has an estimated transmission rate of 0.5–1.4% per sexual act. Syphilis doesn't have an effective treatment, but this disease can be cured in its early stages with one dose of benzathine penicillin G (administered intramuscularly).
