Primary oocyte is a diploid cell formed in foetal ovary when the gamete mother cell, oogonia is arrested at prophase-I of meiosis. Secondary oocyte is the haploid cell formed from primary oocyte that completes its first meiotic division, during puberty and produces the female gamete ova

The swing toolkit, shipped as part of java SE platform, includes a rich set of graphical components for building GUIs and adding interactivity to java applications.

GUI stands for Graphical User Interface. A program's graphical user interface presents an easy-to-use visual display to the user. It is made up of graphical components (e.g., buttons, labels, windows).

1. Define a container to hold components. Examples of containers are : J Frame, J panel, J Dialog etc. 

2. Add required GUI components/widgets to the container. Example of GUI components are : J Button, J Label, J Text Field etc. 

3. Use Layout Manager to determine position and size of components. 

4. Add action to GUI by adding event listeners to GUI components. 

5. Save and test run your GUI application.

Put a tick mark (✓) against the correct alternative in the following statements: 

(a) Function of WBCs is to Provide immunity 

(b) Blood Capillary is a Narrow tube made up of endothelium only. 

(c) Nucleus is absent in RBCs 

(d) The only artery which carries deoxygenated blood is called, Pulmonary artery 

(e) Sphygmomanometer ni’sures Blood pressure 

(f) Pulmonary vein carries Oxygenated blood

(g) The blood tastes saltish due to the dissolved: Sodium chloride 

•  The top level containers are JFrame, JDialog, JApplet. 
• Top level containers and all its child components can be moved, hidden, shown, etc. in a single operation e.g., if you move a container then its child components also move with it; if you hide a container then all of its child controls also get hidden.

(a)  (A + C)(C + D)

= (A + BB’ + C + DD’)(AA’ + BB’ + C + D)

= (A + B + C + D)(A + B’ + C + D’)(A + B + C + D)(A’ + B’ + C + D)

By removing duplicate terms we get canonical Product-of-Sum form:

(A + B + C + D)(A + B’ + C + D’)(A’ + B’ + C + D)

F = π(0, 5 , 12)

F = M0 + M5 + M12

(b) (X + Y)(Y + Z)(X + Z)

= (X + Y + ZZ’)(XX’ + Y + Z)(X + YY’ + Z)

= (X + Y + Z)(X + Y + Z’)(X + Y + Z)(X’ + Y + Z)(X + Y + Z)(X + Y’ + Z)

By removing duplicate terms we get canonical Product-of-Sum form:

(X + Y + Z)(X + Y + Z’)( X’ + Y + Z)( X + Y’ + Z)

F = π(0, 1 , 2, 4)

F = M0 + M1 + M2 + M4

The procedure “Break the line, change the sign” is called demorganization which is performed by following steps :

1. Complement the entire function

2. Change all ANDs ( . ) to ORs ( + ) and all the ORs ( + ) to ANDs ( . )

3. Complement each of the individual variables.

(i)  0 . x = 0

(ii)  ab + a’b’

(iii)  (a + b)(b + c) = 0

(iv)  ((a’+ c)(c’ + a)) + ((b’+ d)(d’ + b)) 

Logical product of several variables is called Minterm and logical sum of several variables is called Maxterm. 

Short hand notation for the maxterms X + Y + Z, X + Y’+ Z, X’+ Y + Z’, X + Y’+ Z’ is F = π(0, 2, 3, 5)

Logical sum having all the variables of a function is called Maxterm.

Short hand notation for the minterms XYZ, X’YZ’, X’YZ is F = ∑(2, 3, 7)

Minterm : xy’z’

Maxterm: x’ + y + z

Minterm: - Minterm is a product of all the literals within the logic system. Each literal may be with or without the bar (i.e. complemented).

Maxterm:- Maxterm is a product of all the literals within the logic system. Each literal may be with or without the bar (i.e. complemented).

Minterm :  x’yz’

Maxterm:  x + y’ + z

Boolean Expression composed entirely either of Minterms or maxterms is referred to as canonical form of a Boolean expression.

(i) Non canonical

(ii) canonical

(iii) canonical

(iv) canonical

(v) Non canonical 

τ is the mean life time of radio nuclide T is the half-life period of radio nuclide, the relation is

τ = 1.44 T

i.e., Mean life period = 1.44 × Half life period

For a function F(X, Y, Z)

(i) Sum of minterms expression is XYZ + X’Y’Z + X’Y’Z + XYZ’

(ii) Non canonical form of Sum-of-products XY + Y’Z + ZX’+ X’Y

Int ind[]=city List. get Selected Indices();

for(i=0;i<array Length;i++)

The fundamental products for each of the input words ABCD = 0010. ABCD = 1101, ABCD = 1110 are as following : 

A’B’CD’ + ABC’D + ABCD’

Following method is used to determine whether 7th item in a list of a list namely My List is selected or not: My List .is Selected Index(7)

ChkList. clear Selection()

Following values of selection Mode are used to ensure that in a list 

(i) Only a single item gets selected - SINGLE 

(ii) Only a single range of items gets selected – SINGLE_INTERVAL 

(iii) Multiple ranges of items get selected- MULTIPLE_INTERVAL

Default list model is a default implementation of list model which offers methods for manipulating list elements.

X = 1, Y = 0, Z = 0 XY’Z’ 

X = 1, Y = 0, Z = 1 XY’Z 

X = 1, Y = 1, Z = 0 XYZ’ 

X = 1, Y = 1, Z = 1 XYZ

The Boolean expression is F = XY’Z’+ XY’Z + XYZ’ + XYZ

Concave lens: P = 1/f = -100/50 = -2D
