On a graph of temperature vs. time, it shows pure substances exhibit a sharp boiling point and a sharp melting point as a horizontal flat line wherein the temperature does not change over time up until all the pure substances boiled or melted. The temperature stays stable at 160°C between 4 minutes and 11 minutes. This horizontal flat line part of the graph is normal of a pure substance. The melting point of a solid substance is usually used to specified if the substance is pure. Likewise, the boiling point of a "liquid" substance can be used to specify if the substance is pure as well.

What does it mean that earlobe attachment is a continuous trait?​
mylen [45]

Answer:

If you decided that the continuous spectrum of earlobe shape was a more accurate way to describe the variation, you aren’t alone.

You need to examine the internal anatomy of both lungs at the same time but can make only one cut. Which plane or planes of the
muminat

The plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;

  • Sagittal
  • Coronal
  • Transverse

<h3>What are body planes?</h3>

Body planes are imaginary geometric planes that are used to divide the body into pieces. They are used to analyze interior organs and systems during anatomical procedures.

We have the following body plane types:

  1. Any vertical plane that separates the body into anterior and posterior halves is referred to as a coronal plane.
  2. Any plane that separates the body into superior and inferior halves and is nearly perpendicular to the spine is referred to as a transverse plane.
  3. Any imaginary plane parallel to the median plane is referred to as the sagittal plane.

Based on the three types of plane sections we have, the plane(s) of the section that would allow me examine the internal anatomy of both lungs at the same time are as follows;

  • Sagittal
  • Coronal
  • Transverse
