Haw May male gametes are produced Palan game |
| Answer» The pollen grain produces two sperm nuclei,one sperm nucleus fuses with the egg nucleus to form an embryo ( process is called syngamy) and another fuses with polar nuclei to form endosperm. This process of fusion of polar nuclei with the sperm to give rise to endosperm is called triple fusion. Since two kinds of fusion—syngamy and triple fusion—take place, the process is known as double fertilisation.\xa0 | |

Explain male and female reproduction |
| Answer» Male Reproductive System: The male reproductive system in human beings is composed of following parts:Testis: There is a pair of testes; which lie in a skin pouch; called *******. ******* is suspended outside the body; below the abdominal cavity. This helps in maintaining the temperature of testes below the body temperature. This is necessary for optimum sperm production. Testis primarily serves the function of sperm production. Sperms are the male gametes. Apart from that, testis also produces testosterone. Testosterone is also called the male hormone, as it is responsible for developing certain secondary sexual characters in boys.Vas Deferens: Vas deferens is the tube which carries sperms to the seminal vesicle.Seminal Vesicle: This is the place where sperms are stored. Secretions from the seminal vesicle and prostate gland add up to make the semen.*****: It is a muscular organ which serves the genitor-urinary functions. The urethra works as the common passage for urine as well as for sperms.Female Reproductive System: The female reproductive system in human beings is composed of following parts:Uterus: This is pear-shaped hollow muscular organ. Uterus is the place where the embryo gets implanted and develops into a newborn baby. The wall of the uterus provides safety and nutrition to the growing foetus.Fallopian Tubes: One fallopian tube comes out from each side at the top of the uterus. The fallopian tubes end in finger-like structures; called flimbriae. Fertilization happens in the fallopian tube.Ovary: There are two ovaries; one near each fallopian tube. Ovary produces the eggs or the female gametes. All the eggs are produces by the ovary when the female child is still in the womb. One egg matures in each ovulation cycle and is released from the ovary. The egg is caught by the flimbriae and transferred to the fallopian tube.******: The cervix (mouth of the uterus) opens into the ******. ****** is a muscular tube-like organs; which serves as the passage for the sperms and also as the canal during the child birth.\xa0 | |

Explain speciation |
| Answer» Speciation is an event that splits a population by evolutionary means into two independent species which cannot reproduce among themselves. Speciation occurs when a population exhibits a continuous change due to changes in the environment. These unit changes get accumulated over a period of time in a section of population which slowly alter the individual\'s structure and functions to give rise to a new species. There are two types of speciation namely allopatric speciation and sympatric speciation.\xa0\xa0 | |

Draw structure of reflex arc |
| Answer» Reflex action in an involuntary action by the body to external stimuli, in which we cannot control ourselves. Reflex actions often bypass the brain altogether to occur very quickly.There are a number of different reflex pathways in the body. A classic example of a reflex pathway can be observed by touching a hot object. Whenever our hand touches a hot object, it triggers a reflex. Signals from the stimulus are transmitted to the spinal cord along the reflex pathway and the spinal cord activates motor neurons, causing the hand to pull away from the hot object.Other examples: Spontaneous movement of our leg, when we stamp on thorn. Closing eyes when light flashes into the eyes.The structural and functional unit that carries out and controls the reflex action is called a Reflex arc. Reflex arcs are formed inside the spinal cord itself. | |

How to find valancy |
|
Answer» We find valency of any elments. Before we should know atomic no of the elment .after knowing atomic no we should eletronic confurgation.last eletrons left in valanced shell is valency of element Consider the following exampleThe atomic number of sodium is 11 (Z=11). The electronic configuration of sodium can be written as 2, 8, 1. 2, 8, 1 electrons are distributed in the shells K, L, M respectively. Therefore, valence electron in sodium is 1 and it needs to lose 1 electron from the outermost orbit to attain octet. Hence, the valency of sodium is 1. |
