A Scanning Electron Microscope (SEM) should be used by Sherman to try to see the 3-dimensional shape of a virus in the patient's sample. SEM is a type of electron microscopy that can scan the surface of the object to be viewed with the help of the beam of electrons and can give clear and detailed structure of that object. It produces the image in 3-dimension.

guapka [62]

Answer:

C) polarity

Explanation:

The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.

  • In water molecules hydrogen bonds provides a special dipole - dipole attraction.
  • Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
  • This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
  • This makes the molecule of water polar.
  • By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.

This property of water is polarity of water.

A sample that ________ is most likely to yield generalizable results.
dimulka [17.4K]
<span>A sample that is large and randomly selected<span> is most likely to yield generalizable results. A large and randomly selected sample shows the real diversity of the population with little relevance of bias within the findings and produces generalizable results. Also, the results from the sample gives accurate representation of the larger population and are easy to use.</span></span>

Drag each tile to the correct box. Explain the process in which hormones secreted by the pancreas function with respect to incre
olga55 [171]

Answer:

The correct order is:

  1. High amount of glucose in the blood, sending signals toward the pancreas.  
  2. Synthesis of hormones by beta cells.
  3. Binding of hormones with receptors on the liver.
  4. Intake of glucose molecules from the blood by specific transporters.
  5. Release of hormones from the receptors  

Explanation:

  • The pancreas produces two hormones important for the regulation of blood glucose levels.
  • The two hormones, glucagon and insulin, increase and decrease the blood sugar respectively.
  • Insulin lowers the blood glucose by stimulating the body cells to increase the intake of glucose.
  • The brain senses high/low blood glucose, then, sends signals to the pancreas to initiate the synthesis of insulin or glucagon by the beta cells.
  • These hormones bind to receptors on body cells; on hepatic cells, in case of insulin.
  • The receptors initiate cellular signaling that facilitates intake or exit of glucose in or out of body cells.
