A first-hand source such as an experiment is called a primary source. 

A primary source is where you can share new information or report on what you have discovered. Some primary sources are research data, interviews, audio recordings, and autobiographies.

A secondary source is where you describe and discuss about the primary sources. They are used to collect and gather primary source information. Some secondary sources are textbooks, review articles, and scholarly books.

A tertiary source is a source about summaries. A tertiary source can be used to look up information or get an overview about what it is you are wanting to know. Some tertiary sources are dictionaries, handbooks, encyclopedias, Wikipedia, and guidebooks.

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>

What is a diffusion through plasma membrane?
yan [13]
Diffusion is the movement of particles from a high concentration area to a low concentration area. Things that can go through a membrane are ions (charged), small polar molecules. Big molecules can't go through the membrane due to its large size and disrupting the membrane. Passive transport is the movement of substances acrpss the cell membrane w/o the use of energy. Active transport needs energy to move substances across a cell membrane.
