You may have seen seeds dispersed on ground and covered with mud. When water is plentiful, the seed fills with water. The water activates special proteins, called enzymes, that begin the process of seed growth (germination) As a .....
We know force is product of mass and acceleration. i.e; F = ma Here, unit of mass is kg and acceleration is m/s2 So unit of force is kg m / s2 , which is combine unit of three fundamental units. Thats why unit of force .....
Yes, I have heard about Lal Bahadur Thapa, the Victorian Cross holder in World War .....
However, the war continued to rage in the Far East. In early August, the US dropped atomic bombs on Hiroshima and Nagasaki, killing at least 100,000 people. Japan surrendered soon after, but the surrender documents were not signed until 2 .....
You write wrong question. I tried make correct. So answer may be .....
Let, l , b and h represents length, breadth and height of the room Given, l = 10 m Rate of carpenting the floor = Rs. 60 sq.m. Cost of carpenting the floor = Rs. 4800. We know, Area of the floor = Cost of carpenting the floor / Rate of .....
Let l, b and h represents length, breadth and height of room repectively. According to question, h = 5m l = 2b Rate of carpenting the floor of room = Rs. 500 per sq. m. Cost of carpenting the floor of room = Rs. 36000. Now, the area of .....
Let l, b and h represents length, breadth and height of room repectively. According to question, b = 2h l = 2b = 2 x 2h = 4h Rate of carpenting the floor of room = Rs. 500 per sq. m. Cost of carpenting the floor of room = Rs. 64000. Now, .....
Here, Height of the room (h) = 6m. Rate of carpenting the floor = Rs. 40 per sq. m. Cost of carpenting the floor = RS. 4000. Now, The area of the floor = Cost of carpenting the floor / Rate of carpenting the floor .....
Here, Lenght of the hall (l) = 18 m. Breadth of the hall (b) = 12 m. Height of the hall (h) = 4 m. We know, Area of 4 walls .....
Here, Length of the room (l) = 6 m. Breadth of the room (b) = 5 m. Height of the room (h) = 3 m. We know, The area of 4 walls (A) = 2h(l +b) .....
Significances of variations are as follows: 1. The variant species (species undergone variation) are more adapted. So, variation increases the chance of survival of an organism in a changing environment. 2. If there were no .....
Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) or thymine (T). The two strands are held together by bonds between the bases. Adenine forms a base pair with thymine, and cytosine forms a base pair with .....
Survival of the fittest is the idea that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. According to the Darwin, out of the vast number of individuals which compete for a place in the .....
Insects lay hundreds of eggs. A female rabbit gives birth to six young ones in one litter and produces four litters in a year. Six- month-old rabbit is capable of reproduction. If all the rabbits survived and multiplied at this rate, their number .....
Heredity has to do with the transfer of (hereditory unit, character or trait) from the parents to their offsprings . Variation is difference in the features of the offsprings due to heredity. The relationship between the two is .....
Here are some points about the importance of gene
It gives you characters that you have, hair colour, eyes colour, skin colour, etc. It gives you genes that code proteins needed for your cells to function, so u you can live. It gives .....
Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are .....
Two differences between DNA and RNA on the basis of nitrogen bases and pentose sugar are: 1. DNA consists of four types of nitrogen bases like adenine, guanine, thymine and cytosine whereas, RNA consists of four types of .....
Variation occurs when one gene in the organism is mutated. If this allows the organism to survive longer than the others in the population without the mutation, it gives the mutated organism a higher chance to pass on its genes. When these genes .....
DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the .....
When organisms reproduce, all the information for growth, survival and reproduction for the next generation is found in the DNA passed down from the parent generation. In sexual reproduction, genetic material is combined from two parents and .....
Hereditary are the characters which are inherited by the offspring from the parents. These traits are present in the form of genetic material, DNA. Genetic material is carried by the vehicles of inheritance, the chromosomes. Each gamete of .....
Survival of the fittest is the idea that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. According to the Darwin, out of the vast number of individuals which compete for a place in the .....
Continuous Variations: 1. The variations fluctuate around an average or mean of species. 2. Direction of continuous variations is predictable. 3. They are already present in the population. 4. Continuous variations are formed due to chance .....
Mutations happen for several reasons. Here I provided two points. 1. DNA fails to copy accurately Most of the mutations that we think matter to evolution are "naturally-occurring." For example, when a cell divides, it makes a copy of .....
While natural selection theory explains survival of the fittest, it does not explain the arrival of the fittest. Natural selection cannot account for degeneracy—To say an organ is no longer useful and, hence, disappears, is to state .....
Natural selection is the process by which forms of life having traits that better enable .....
Wilhelm Johannsen introduced the term 'gene'. The history of genetics started with the work of the Augustinian friar Gregor Johann Mendel. His work on pea plants, published in 1866, described what .....
