<h2>ANSWER:</h2>

 to view thin specimens

<h2>EXPLANATION:</h2>

There are two main models of an electron microscope – the transmission EM (TEM) and the scanning EM (SEM). The transmission electron microscope is utilized to observe thin specimens (tissue sections, molecules, etc) by which electrons can move to create a projection image. A normal TEM can reach the highest magnification level of about 1,000,000x.

. What is the relationship between quantity demanded and quantity supplied at equilibrium? What is the relationship when there i
Zanzabum

Answer:

  • At equilibrium, the quantity of a commodity demanded is the same as the quantity of that commodity supplied. i.e. QD = QS. The price at which QD = QS is the equilibrium price.
  • When there is a shortage, the quantity of goods demanded would be greater than quantity supplied, as the price falls below the equilibrium price. i.e. QD>QS
  • When there is surplus, the quantity of goods demanded is less than the quantity supplied, as price increases above the equilibrium price. i.e. QD<QS.

For example, in the table showing the demand and supply schedule for T shirt at different prices (see file attached), the equilibrium price for a unit of T shirt is $3, at equilibrium, QD = QS (i.e. 30 = 30).

A shortage is recorded when the price of T shirt falls below equilibrium price of $3 as shortage of T shirt is recorded, i.e. @ $2, QD>QS (40>20). A shortage of 20 is recorded.

Surplus occurs as price increases above equilibrium price of which QD<QD, i.e. @ $4, a surplus of 20 is recorded.

Disassembly of the nuclear envelope ________________. select one:
Alex777 [14]
Disassembly of the nuclear envelope must occur for kinetochore microtubules to form in animal cells. This disassembly of nuclear envelope is triggered by the cyclin-dependent kinase at the onset of mitosis. The reassembly is mediated by multiple interactions of the INM proteins with chromatin. Dephosphorylation of INM proteins at late anaphase/telophase is required for nuclear envelope reassembly.
