What is homologous animals? |
| Answer» Homology refers to two things that have an equivalent role or relationship. Homology is important in comparative biology since it makes it possible to determine if two different animals or plants share a common ancestor. Essentially, homology in this context means that there are two species that have related parts that do similar things, but that are not exactly the same.Homology In the Animal KingdomFollowing are some examples of homology:1) The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits. They are considered homologous structures because they have a similar underlying anatomy.2) The pelvis of a dog, of a cat and of a human and of a snake are homologous structures.3)The tailbone of a human being and the tail of a monkey are examples of homology. The tailbone is actually called the tailbone because of this shared lineage. Because a human doesn’t actually have a tail but the tailbone is the last vestige or remains of where a tail would be, it is referred to as “vestigial.” | |

Why sky is blue and why it is red at the time of sunset or sunrise? |
|
Answer» I think Scattered of light At the time of sunrise or sunset when the sun is near the horizon, the sunlight has to travel the larger distance through the atmosphere to reach us. During this long journey of sunlight , most of the shorter wavelength blue-colour present in it is scattered out and away from our line of sight. So, the light reaching us at the time of sunrise and sunset consists mainly of longer wavelength red colour due to which it appears to be red. Atmospheric refreaction....see clear explanation in schand book Blue color of the sky is on account of scattering of light of shorter wavelength by particles in the atmosphere on the other hand In early morning, the sun is situated near the horizon light from the sun passes through thicker layers of air covers a larger distance in the earth\'s atmosphere before reaching our eyes. While passing through atmosphere blue light is mostly scattered away and the sun appears Reddish Due to atmospheric refraction |

What is triple fusion& double fertilization? |
| Answer» Double fertilisation is the combination of syngamy and triple fusion. Double fertilization is unique to flowering plants. Events during fertilisation are elucidated.*As the pollen grain falls on the stigma of the flower, it germinates and forms a pollen tube. Pollen tube is guided by the secretions of the ovule. Pollen tube enters the micropylar region of the ovule.*Embryo sac inside an ovule consists of antipodals, synergids, egg cell, a central cell with two polar nuclei.*As the pollen tube releases two male gametes into synergids cytoplasm. One of the male gametes fuses with the nucleus of egg cell by the process of syngamy (first fertilisation) to form diploid zygote(2n).*The other male gamete fuses with the central cell and forms primary endosperm nucleus (PEN). This fusion is called as triple fusion. After the triple fusion the central cell is called as primary endosperm cell. | |
