Answer: color, cleavage, clarity, durability, and crystal system

Explanation: color - distinctly green color that ranges between bluish green and slightly yellowish green.

cleavage - one direction of imperfect cleavage

clarity - almost every natural emerald has eye-visible characteristics that can be inclusions, surface-reaching fractures, or healed fractures. Treatments to fill the fractures with oils, waxes, polymers, flux and other materials to reduce their visibility has been common practice for hundreds of years.

durability - emerald is very hard, but almost all specimens have inclusions and surface-reaching fractures that compromise their durability

crystal system - hexagonal

A 12-year-old child sustains a moderate burn injury. the mother reports that the child last received a tetanus injection when he
Phoenix [80]
The nurse should administer an injection of postexposure prophylaxis for tetanus. Tetanus is a toxic substance produced by a bacterium that cannot survive air (oxygen) exposure, that is why deep wounds are more vulnerable to tetanus. A moderate burn injury is considered an open dirty wound, therefore the patient should be protected from tetanus.
There is a vaccine for tetanus, that provides immunization from this disease, but it needs to be repeated every 10 years. However, in cases where there is an open dirty wound, the vaccine is believed to be inactive if it was not done within the last 5 years.
In this case, the child will not receive the tetanus vaccine, but an injection of active immunization, which acts much faster, but does not last as long as the vaccine.

Which term describes the school of psychology that studies the reasons for behavior and how organisms adapt to environments?
vitfil [10]

Answer:

C

Explanation:

I was not quite sure what if my answer was correct, so using the process of elimination, I determined that it was.

Although Psychoanalysis seems like the correct answer since it looks close to the word Psychology, it is not the right because this term means a therapy to help mental illnesses, so that would not be the correct answer.

I continued to use the same process and I came to the conclusion that C is the correct answer.

Structuralism is when you try to understand the aspects of human cognition, behavior, culture, etc.

Hope this helps.

The lower rocks in the Muav limestone are 505 million years old. The upper rocks in the Redwall limestone are 340 million years
Alex777 [14]

Unconformity

Explanation:

The gap between the lower and upper limestone layer can be explained by the occurrence of an unconformity.

An unconformity is a break in stratigraphic record usually marked a prolong period of non-deposition or erosion.

A major break of several millions of years is called a hiatus. A minor break is a diastem.

  • During a period of non-deposition, no materials are brought into the basin.
  • This can last for several years until deposition resumes again.
  • Such a prolonged period of non-deposition causes a break in stratigraphic record.
  • At other times, stratigraphic records can be lost to erosion.
  • Erosion entails the washing away of the earth.
  • This will ultimately cause the loss of records between two strata till deposition resumes.
  • In most strata, periods of non-deposition and erosion usually takes place hand in hand.
