In sexual reproduction of eucaryotic microorganisms, as well as macroorganisms, a new individual is formed by the fusion of two different sex cells known as gametes, which are usually from two parents of different .....

We know, Tan (A - B)= (tan A - tan B) / (1 + tanA tanB)   A=50o. B=40o .  Then, Tan 50 = cot (90-50)=1/tan40. LHS = tan(50-40) x (1+ tan50 tan40) = tan10o x (1+1) = 2 tan 10o. Hence, Tan 50o = tan40o .....

Yeast size can vary greatly depending on the species, typically measuring 3-4 µm in diameter. Most yeasts reproduce asexually by an asymmetric division process called budding. In planarian reproduction, both sexual reproduction and the .....

Let the threee consecutive integers be x, x + 1, x + 2. Average of three consecutive integers = (x + x + 1 + x + 2)/3 = (x + 1) From condition, (x + 1) <= 12 or, x <= 11. So, the greatest x is 11. So, the greatest integers are 11, 11+1, .....

The acid produced by ants and honeybe is called formic acid. The name comes from the Latin word for ant, which is “formica.” Chemically, it is a simple carboxylic acid ( .....

'Sati pratha', a custom of a woman, being burned alive in the same fire as that in which her dead husband's body is burnt, was abolished in 1977 BS. The slavery system in the society had been discouraged by many rulers like Bhimsen .....

Power(P) = 1/ focal length(f) When P = 1 dioptre, 1 = 1/ f Therefore, f = 1 m. So, Power of the lens is 1 dioptre means that the focal length of the lens is 1 .....

Humans have 46 chromosomes in each cell. During fertilization of the egg, the sperm nucleus containing 23 chromosomes from the paternal side fuses with the nucleus of the egg that contains 23 chromosomes from .....

Tundra region is called cold desert. Snowfall occurs instead of rainfall in this climatic zone. Vegetation is poor and population very thin. Summers are cold and .....

You know that heat comes from the sun. Land heats up quicker than oceans. Oceans hold heat longer, though, because land cools quicker than oceans do. This uneven heating and cooling of different parts of the Earth causes winds. Winds move clouds .....

The character which is seen in the first generation (in Mendel's experiment) is dominant character and the character which is not seen in the first generation is recessive character.  e.g. When a cross is made between a pure tall and pure .....
