Ques 1: What is the importance of DNA copying in reproduction?   Ans 1: DNA (Deoxyribonucleic acid) is the genetic material found in the chromosomes, present in the nucleus of the cell. The DNA (Deoxyribonucleic acid) is the information site for making proteins and each specific type of protein leads to the specific type of body design.  Thus, it is the DNA molecule that specifies the body design of an individual. Therefore, it can be concluded that it is the DNA that gets transferred from parents to their offsprings and makes them look similar.   Ques 2: Why is variation beneficial to the species but not necessarily for the individual?   Ans 2: Variations are beneficial to the species than individual because s sometimes for a species,  the environmental conditions change so drastically that their survival becomes difficult.   For example, if the temperature of water increases suddenly, then most of the bacteria living in that wate...

Ques 1. Mention the condition when an object is in motion (a) can be considered point object (b) can not be considered point object.  Ans . An object can be considered as a point object if (a) its size is negligible in comparison to the distance travelled by object (b) it's size is not negligible in comparison to the distance travelled by object. Ques 2 . Can Earth be regarded as a point object when it is describing its really journey around the sun? Ans.  Yes, because the diameter of earth is very small as compared to the radius of the orbital path of earth around the sun.   Ques 3. Can the speed of a body be negative?   Ans . No, because the speed of an object is the distance travelled by the by object in unit time and distance can never be negative. Ques 4. which speed is measured by the speedometer of your scooter?  Ans . The Speedometer measure the instantaneous speed of the scooter at a given instant of time. Ques 5.What does th...
