Answer:
true
Explanation:
Cerebrospinal fluids is a colorless fluid that is secreted in the choroid plexus,and circulates in the ventricles system and sub -aranchinoid space of the brain and spinal cord. its provides nutrients to the surrounding neurons, cushions the effects of trauma, pressure, acts as buffer and provides protection through immune system .
it plays a vital role in regulating blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.
in order to analyze it to diagnose some neurological diseases its sample is usually taken out in a process called lumbar puncture.
Answer: In Spanish
¿Cómo se vuelven resistentes las bacterias a los antibióticos?
R: Las bacterias pueden volverse resistentes a los antibióticos de varias maneras. Algunas bacterias pueden "neutralizar" un antibiótico cambiándolo de una manera que lo hace inofensivo. Otros han aprendido a bombear un antibiótico fuera de la bacteria antes de que pueda causar algún daño. Algunas bacterias pueden cambiar su estructura externa, por lo que el antibiótico no tiene forma de adherirse a la bacteria que está diseñada para matar.
Después de exponerse a los antibióticos, a veces una de las bacterias puede sobrevivir porque encontró una manera de resistir el antibiótico. Si incluso una bacteria se vuelve resistente a los antibióticos, puede multiplicarse y reemplazar todas las bacterias que fueron eliminadas. Eso significa que la exposición a los antibióticos proporciona una presión selectiva que hace que las bacterias sobrevivientes sean más propensas a ser resistentes. Las bacterias también pueden volverse resistentes a través de la mutación de su material genético.
Answer in English :
How do bacteria become resistant to antibiotics?
A: Bacteria can become resistant to antibiotics through several ways. Some bacteria can “neutralize” an antibiotic by changing it in a way that makes it harmless. Others have learned how to pump an antibiotic back outside of the bacteria before it can do any harm. Some bacteria can change their outer structure so the antibiotic has no way to attach to the bacteria it is designed to kill.
After being exposed to antibiotics, sometimes one of the bacteria can survive because it found a way to resist the antibiotic. If even one bacterium becomes resistant to antibiotics, it can then multiply and replace all the bacteria that were killed off. That means that exposure to antibiotics provides selective pressure making the surviving bacteria more likely to be resistant. Bacteria can also become resistant through mutation of their genetic material.

For the answer to the question above, <span>Blurred Vision
A severe headache, visual disturbances such as blurred vision and some epigastric pain that is associated with the development of severe pre-eclampsia or eclampsia. These danger signs and symptoms must be reported immediately as soon as possible. A severe headache and visual disturbances are related to severe vasoconstriction and in a severe increase in blood pressure. Epigastric pain is related to hepatic dysfunction. Ankle edema is a common thing during the third trimester of pregnancy. However, the facial edema is associated with increased fluid retention and the progression from mild to severe pre-eclampsia. Increased energy levels aren't associated with a progression of the client's pre-eclampsia or the development of the complications. In fact, some women are reporting an "energy spurt" before the onset of labor. A mild back-ache is just a common discomfort of pregnancy, unrelated to a progression of the client's pre-eclampsia. It also may be associated with bed rest when the mattress is not firm. Some multi-parous women have reported a mild backache as a sign of impending labor.</span>
