The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

Llana [10]

Meninges refers to the three layes of membranes surrounding the brain and spinal cord of the mammals. The inflammation of these protective membranes of the brain and the spinal cord caused by the infection of bacteria, virus or other microorganisms is called the meningitis.

A laboratory test to identify or rule out meningitis is the analysis if the cerebrospinal fluid (CSF) by lumbar puncture. CSF is a colorless fluid filling the ventricles of the brain and the central canal of the spinal cord. Lumbar puncture is a techinque of isolating the CSF from the sac sround the spinal cord using a needle under a local anesthetic. The sample is then analysed for the opening pressure which is normally between 6 and 18 cm of water in a patient who is not infected with meningitis. Also, the levels of glucose in CSF is above 40% of that in blood in non-infected persons. If lactate levels are less than 35mg/dl, this will also rule out meningitis.

Can someone explain eukaryotic cells and prokaryotic cells like you’re talking to a 5 year old?
Fed [463]

Eukaryotic cells do not have a nucleus. The nucleus is where DNA, your genetic material, is usually stored. Prokaryotic cells do not have a nucleus. The DNA just floats around the cell instead of staying in one designated area.

What is one change that would cause more water to evaporate from a stream?
Svetllana [295]

Evaporation

Explanation:

Evaporation is one change that would cause more water to evaporate from a stream.

Evaporation is a phase change in which liquid is changed into its gaseous form.

  • When a substance is heated from solid to liquid, it melts.
  • After melting, additional heat causes a phase change that allows for the liquid to change to gases.
  • In the water cycle, the sun provides heat energy that causes surface water in streams to be heated.
  • This leads to evaporation of the surface water into the atmosphere where they can be condensed to form precipitation.
