Fertilisation takes places |
| Answer» A pregnancy starts with fertilization, when a woman\'s egg joins with a man\'s sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus.

In natural conception, the male sperm fertilizes the female egg inside the woman\'s body. While many think fertilization occurs in the ovary, it actually takes place in the fallopian tube just outside the ovary. | |

What is the relationship of homologous organs and anologous organs with evolution |
| Answer» \tCharacteristics assist us to trace the evolutionary relationship between organisms. Evolutionary relationships help us to trace who we are more close to and who is our common ancestor.\tA group of organisms is similar enough to be thought of together by certain characteristics.\tFor instance, mammals and reptiles. All of them have four limbs and the basic structure of their organs is similar even though they use it for different functions. Such organs are called homologous organs. This does not mean that they share a common ancestor.\tSome organisms appear to be similar but basic designs are different.\tFor instance, wings of bats and birds. Both of these animals use wings for the same function but they have different basic structures. Such organs are called analogous organs.\tThus, the homologous and analogous characteristics help to trace an evolutionary relationship between different species. | |

How to star appear their actually position |
| Answer» \tThe twinkling of stars is also due to atmospheric refraction.\tThe air in the earth\'s atmosphere is such that it has increasing refractive index\tWhen starlight enters earth\'s atmosphere it undergoes multiple refraction continuously before it reaches the earth .\tBecause of the increasing refractive index, the starlight bends downwards (ie towards the normal) and thereby the apparent position of the star is slightly higher than its actual position. | |

If we cross flowers havimg purple and violet what is colour in f¹ progeny |
|
Answer» violet In pea plant violet colour flower is dominant over white colour flower.When true-breeding violet flowered plants were crossed with true-breeding white flowered one, the offspring of F1 generation were all found to bear violet flowers. The trait of white colour was suppressed and violet colour trait dominated. Thus, the law of dominance was established with white flowers being the recessive trait and violet flowers being the dominant trait. It can be represented in a Punnet square, thus:In the next cross, we take the two hybrids (Vv) of the F1 generation and cross them. We find 75% of the offspring of the F2 generation show the dominant trait while 25% show the recessive trait of the parental generation. Thus, the law of purity of gametes was established. It can be represented in a Punnet square, thus: |
