Understand and analyse the syllabus First cover the chapters you find easy quickly and then proceed to the chapters which you find difficult and give them proper amount of time and concentration After you have covered all the syllabus just attempt some mock tests and attempt the previous year question papers you can even download some separate papers for mental ability test and scholastic aptitude test from the internet aur even the my CBSE guide app As you know that that social science has a major wastage of marks that is 40 marks so focus on that and make sure your covered every chapter at least once That is my strategy and and I hope It helped you.... Good luck buddy ?

1. Apply the question to yourself

This is the best way to solve blood relation questions. Here you try and relate every statement to yourself. The starting name of the statement could be assumed as your name or you

<a name="more"></a>
 

2. Break the question into very small parts

When the statement is very long, it can get confusing. So break down every statement in the question into sub statements and solve the question.
 

3. Do not assume the gender

Do not assume the gender of any person in the question just based on the names given in the question.
 

4. Draw clear diagrams as you solve

An easy trick to solve such questions with 100% accuracy is to draw a family try where people of the same generation are placed at the same level and the entire diagram is in the form of a hierarchy.

Indicate + for Male candidate
Indicate – for Female candidate
Indicate <=> for Couple
Indicate - - - - for Same Generation like brother - - - brother (or) sister - - - sister (or) sister - - -brother
Indicate–––––for Different generations like father–––––son (or) mother––––son (or) father––––daughter (or) Mother ––––– daughter

ANSWER

 

Let A and B start from point O. 

A goes 3 km North and then turns rights and covers 4 km

B turns right and walks for 5 km and then turns right and walks 3 km. 

So A and B are apart by 5+4 km = 9 km.

option A

According to the theory old cells split into new cells and the formation of new cells is known as cell division or cell production. This was firstly observed by Flemming in 1882 but an extensive in details was given by Belar in 1920.

Usually cell division is of three types:

(i) Amitosis (ii) Mitosis (iii) Meiosis

Amitosis: This cell division takes place in less developed cell of unicellular organism and firstly nucleus of the cell is divided and then later cytoplasm, ultimately two new cells are formed. In bacteria, blue-green algae, yeast, amoeba, protozoa etc this type of cell division takes place.

Mitosis: This cell division is also known as Somatic cell division in which two identical cells are produced. Although cell is divided but number of chromosomes remains the same and mitosis is a continuous process. Various phases like prophase, metaphase, anaphase, telophase, cytokinesis occur and cell divides itself stage by stage.

Prophase: First stage of mitosis.

- In all animal cells and in some plants like fungi and some algae.

- The centriole duplicates itself and divides two new centrioles (centrosomes) move to opposite ends of the cell (poles).

- The spindle fibres or series of fibres radiates from vicinity of each centriole towards the nucleus.

- Except fungi and some algae the spindle fibres develop without the presence of centrioles.

- The chromosomes which are already duplicated become shorten and thicken.

- Chromatids are the duplicated halves of each chromosome which are held together by the centromere.

- The nucleus and the nuclear membrane begin to disintegrate in the late prophase.

Metaphase:

- The pairs of chromosomes align themselves in such a way that the centre of the cell and each centromere becomes attached to one spindle fibre from each pole.

- The centromere divides and the separated chromatids become independent daughter chromosomes.

Anaphase:

- Spindle Fibres begin to shorten.

- This exerts a force on the sister chromatids that pulls them apart.

- Spindle fibres continue to shorten, pulling chromatids to opposite poles.

- This ensures that each daughter cell gets identical sets of chromosomes.

Telophase:

- The chromosomes decondense.

- The nuclear envelope forms i.e nuclear membrane forms around each new group of chromosomes.

- Daughter chromosomes reach the poles.

- Spindle fibres totally disappear.

Cytokinesis:

- After the division of nucleus, cytoplasm starts to divide.

- The original large cell becomes two smaller identical cells and each daughter cells take food, grows, being divided and the process continues.

- It maintains the continuity of metabolism by transmitting to the daughter cells.

- Plays significant role in wound healing, regeneration of damaged parts (like tail of lizard), the replacement of cells (the skin surface), and it may give rise to tumours or cancerous growth if uncontrolled process be occur.

*In mitosis it is also ensured that two daughter cells inherit the same number of chromosomes and hence have the same characteristics as the parent cell.

Meiosis: It is a special type of cell division that occurs in Sexually Reproducing organisms and thus gametes (*** cells) are produced. It consists two successive cell division that resembles like mitosis but chromosomes are duplicated only once. Thus, gametes have half the number of chromosomes normally found in the body cells. Two sub stages – meiosis I and meiosis II occur.

• Meiosis I: Can be broken down into four sub stages: Prophase I, Metaphase I, Anaphase I and Telophase I.

• Meiosis II: Can be broken down into four substages: Prophase II, Metaphase II, Anaphase II and Telophase II.

Meiosis I:

Prophase I: Most of the significant processes of Meiosis occur during Prophase I

- The chromosomes condense and become visible.

- The centrioles form and move toward the poles.

- The nuclear membrane begins to dissolve

- The homologous pair up, forming a tetrad

- Each tetrad is comprised of four chromotids.

- Homologous chromosomes will swap genetic material in a process known as crossing over which increase genetic diversity by creating four unique chromatids.

Metaphase I:

- Microtubules grow from the centrioles and attach to the centromeres where tetrads line up along the cell equator.

Anaphase I:

- The centromeres break, cytokinesis begins and homologous chromosomes separated but the sister chromatids are still attached.

Telophase I:

- Depend upon species the chromosomes may decondense and cytokinesis reches to its completion by creating two haploid daughter cells.

Meiosis II:

Prophase II:

- The nuclear membrane dissolves, centrioles form and move toward the poles.

Metaphase II:

-  Microtubules attach to the centromeres and grow from the centrioles and the sister chromatids line up along the cell equator.

Anaphase II:

- Cytokinesis begins, centromeres break and sister chromatids separate.

Telophase II:

- Depends upon species chromosomes may decondense, Cytokinesis reaches completion creating four haploid daughter cells.

Thank you for answering my question.

Anuj Mittal 3 years, 6 months ago

F= - 10 CM

H1 =2.5 CM

U = -30CM

{tex}{ 1\over F } = {1\over v } -{ 1\over u}{/tex}

  1/-10=1/v -1/-30

1/-10 +1/30  = 1/v

(-3+1)/30=1/v

-2/30 = 1/v

-1/15 =1/v

v = -15

position is on left side 15 cm away from the lens

{tex}{H2 \over H1 } = {v \over u}{/tex}      

H=  (-15*2.5)/-30

H= 1.25 cm

as it is positive so image is virtual and erect
