The answer is A.It releases spermicide into the uterus to keep sperm from fertilizing eggs. Hope this helps
Medical diagnosis is the process of determining which disease or condition explains a person's symptoms and signs.It basically enables the doctor understand what disease is the patient going through.
Diagnosis is often challenging, because many signs and symptoms are nonspecific and different diseases also have them.
For example, redness of the skin is a sign of many disorders and thus does not tell the healthcare professional what is wrong.
<h2><u>Answer:</u></h2>
The correct option is A ( Technology has advanced and improved over time.)
<h3><u>Explanation: </u></h3>
Advancement is advancing and associations over the entire world are feeling the impacts whether it's sure or negative. Anyway, the advances of development have positively affected the matter of master games.
Everything running from minute replays to tweeting your most adored capable contender, development passes on individuals a great deal closer to the delight than whenever in ongoing memory.
Advances in development have even made it functional for an individual actually side of the world to watch a specialist wearing event continuously that is happening in another country, globalizing sports.
Answer:
The correct answer will be-
1. Proteins
2. Nervous
3. transmissible spongiform encephalopathies.
4. Mad cow disease
5. Cow
6. Virus
Explanation:
Prions are the infectious particle composed of harmless proteins found in the brain of the animals like humans, cows which are responsible for the degeneration of the nervous tissues of the brain.
These proteins of the prions are resistant to the enzymatic actions and thus they can multiply and accumulate within the neurons and destroys them forming holes in the neurons giving the sponge-like appearance and thus disease is known as transmissible spongiform encephalopathies.
An example of this disease is mad cow disease which spreads from the cow to human by eating the meat of the cow especially brain contaminated with prions which are neither considered viruses nor cells.
Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
