In endothermic reaction in which heat is absorbed but in exothermic the heat is released . Ex- 2Mgo+heat------>2Mg+o2

Ankit Raj 3 years, 6 months ago

Exothermic - A reaction in which heat is released. Ex- respiration Endothermic - A reaction in which head is absorbed. Ex- CaCO3+ heat -----> CaO + CO2

What do you mean by pairasitic

Udit Paliwal 2 years, 10 months ago

They should be connected in parallel because if one component doesn't work others will work in parallel combination.

Photosynthesis in brief is plants ko bhook kagti hai aur voh khana banate hain

Utkarsh Mishra 3 years, 6 months ago

Photosynthesis is the process by which green plants make their own food carbon dioxide and water by using sunlight in the presence of chlorophyll. 6CO2 (carbon dioxide)+ 6H2O(water) ------> C6H12O6(glucose) + O2(oxygen) Condition necessary for photosynthesis 1) Carbon dioxide 2) Water 3) Sunlight 4) Chlorophyll

Prachi Gupta 3 years, 6 months ago

Photo synthesis is a process in which green plants make their own food from simple inorganic substances like carbondioxide and water in the presence of sunlight and chlorophyll. 6CO2 + 6H2O + light energy(sunlight) ------> 6O2+ C6H12O6(glucose).

Manthan The Bro 3 years, 6 months ago

But according to me ncert is not enough you have to use guides for study

Rishabh Sharma 3 years, 6 months ago

Not for science also for science use s Chand lakhmir singh manjit Kaur book for physics chemistry and biology this is best for science

Shubham Sagar 3 years, 6 months ago

Yes,you can score 100% if you read only ncert in science ,but when we talk about maths ncert is good to score only 50-60 percent in boards,but if you want to score 100 percent in maths Then follow these Books (1) RD sharma (2) RS Aggarwal (3) all in one - arihant But if you don,t want to do any of these books then do any of these sample paper along with ncert (1) educart (2) arihant (3) oswaal

Not mirror , lens

Pramod90000 Sharma 3 years, 6 months ago

Concave mirror is converging mirror , convex mirror is diverging mirror .Always convex have virtual and erect image formation but concave mirror formed a real image or may be.

Hema Sri 3 years, 6 months ago

Thank you guys

Divya Singh 3 years, 7 months ago

Sis concave mirror have virtual focus and convex lense has real focus Concave lense is diversing lense Convex lense is converging lense Ray digram of concave lense is just like convex mirror and Ray digram of convex lens is same like concave mirror

Sk Muzamil Bux 3 years, 7 months ago

Concave lens is converging Convex lens is diverging

We can find the valency of an atom by its atomic number . With the help of atomic number we will fill the K, L and M shells with the k shell with the help of 2n² law and the rest shells with octat law and after filling the number of electrons in the last shell decide the valency... If it satisfy the laws and have 8 or 2 electrons in the last shell then it is a balanced atom but if not then the number of electrons in last shell are the valence electrons. For eg. Sodium Atomic number 11 Configuration - 2,8,1 ( valence electrons - 1) To balance sodium now according to octat law its better to give 1 electron to other then having 7 electrons so if gives 1 electron to other it will have a positive charge • Na+ that's why.. Chlorine as like it needs 1 electron to balance its atom so if the electron is taken then it contains negative charge..so Cl- It will be my pleasure if u get it

Heterotrophic nutrition are those nutrition which organism do not make their own food it depend on other organism for their food .Ex - Human beings

Utkarsh Mishra 3 years, 6 months ago

Autotrophic nutrition is that mode of nutrition in which organisms makes its own food from simple inorganic materials substance like Carbon dioxide and water presence in the surrounding. The autotrophic organisms contain green pigment, Chlorophyll which is capable of observing sunlight. There are two types of autotrophic mode of nutrition 1) photosynthetic 2) chemosynthetic Heterotrophic nutrition is that mode of nutrition in which organisms do not make their own food from simple inorganic materials like Carbon dioxide and water and depend on other organism for their food. All the animals,most of the bacterias, fungi and non-green plants have heterotrophic mode of nutrition. There are three types of heterotrophic nutrition 1) Saprotrophic (sapra means ratter) 2) Parasite 3) Holozoic

First see its electrons in outermost shell if they are less than 4 then valency is same as electrons but if it exceed 4 or it is 4 subtract those electrons from 8. Remaining is the valency
