Answer:

The correct answer is A. The water particles must have lost energy.

Explanation:

The freezing point is reached in a solution when the kinetic energy of the molecules becomes smaller as the temperature decreases; the increase of the intermolecular forces of attraction and the decrease of the kinetic energy are the causes of which the liquids crystallize. Solutions always freeze at a lower temperature than pure solvent. The freezing temperature of pure water is 0 ° C.

A) the water particles must have lost energy. As things get warmer, the particles have more kinetic energy and begin to move faster.

Glia that provide myelin for neurons in the brain are called ________.
kati45 [8]

Answer:

oligodendrocytes

Explanation:

Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons.  These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.

It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.

Dean is a crime scene photographer. In which order should he photograph the crime scene?
Artemon [7]
There is no prescribed length of time it takes to photographically document a crime scene. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. It can consist of thousands of photographs and hours of work.
Crime scene photography should not just focus on the obvious. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. Relatives noted that the victim did not drink beer. Further investigation led the team to the convenience store where the beer was purchased and the surveillance tape showed the victim with an unknown person purchasing the beer. It turns out that the victim had picked up a hitchhiker, purchased beer for that person and come back to the house. The photograph of the refrigerator contents had created the link enabling the investigators to find the suspect.
