Bipedal locomotion means |
| Answer» Bipedal locomotion refers to walking on two legs in an upright position, and the only animal to do that all the time is the modern human. Our ancestor primates lived in trees and rarely set foot on the ground; our ancestor hominins moved out of those trees and lived primarily in the savannas. Walking upright all the time is thought to have been an evolutionary step forward if you will, and one of the hallmarks of being human. | |

What is meant by contrasting character |
| Answer» Each characteristic in an organism is represented by two factors (it means that each cell has two chromosomes, carrying the gene for the same character).When two contrasting factors (opposite factors) are present in an organism then one of them can mask the presence of the other. Therefore, one is called the dominant factor , while the other is called the recessive factor\xa0 | |

Why dimond is non metal |
|
Answer» Due to the fact that they are made of nan metal material. Diamond is madeof very ordered carbon atoms. And it is the 6th element, which is found on the right side of the periodic table, so it is a non metal . It is a modified form of carbon which is non metal It cannot posses the properties of matals like mellablity,ductility,sonorus etc so it is non metal |

in periods why atomic size decreases?? |
| Answer» Atomic size is the distance between the centre of the nuclei and its outermost orbit. In simple terms, it is the radius of an atom. It is noticed that the atomic size of elements decrease as we move from left to right in a period. This is because the electrons increase hence increasing the nuclear charge. | |

Why silicon doesnt have a large no of compounds yet carbon and silicon both are tetravalent? |
| Answer» The carbon’s four valence electrons can be shared by other atoms (that have electrons to share), thus forming what we call covalent bonds (shared electrons bonds). The carbon atom also has the ability to form a bond with other carbon atoms to create covalent bonds forming long strings of carbon atoms, bonded to each other like links in a chain.Silicon (Si), another element in group 14 of the periodic table, also has four valence electrons and can make large molecules called silicones. But due to its higher atomic number (in comparison to Carbon), its atoms are too large to fit together into as great a variety of molecules as carbon atoms can. | |
| 55530. |
What is meant a group and a period in a periodic table |
| Answer» A group is a family of elements each having the samee valence electrons and thus, having the same chemical properties eg alkali metals it is vertical arranged in the periodic table.While a period contains elements with the same principal quantum number example oxygen and nitrogen or with the same number of valence shells arranged horizontally in the periodic table. Hope it was helpful. | |

What is the difference between speciation and evolution..? |
| Answer» Evolution is defined as evolution of different organisms from one common ancestor. For example, humans and apes evolved from a common ancestor. Organisms are different from each other due to various adaptations accumulated over time, humans evolved to become more intelligent than apes and developed complex languages for communication.This image is an oversimplified illustration of human evolution.Speciation on the other hand, is the diversion of a single organism\'s population into 2 or more genetically different groups. Speciation is caused mainly because of isolation of two groups of the organism\'s population, mostly geographic which leads to reproducive isolation, meaning the two groups stop breeding with each other.Neanderthals and modern humans were two separate species of the same organism, humans. | |

Define conductance and conductivity ?write their SI unit |
| Answer» Conductance: The ability of a system to conduct electricity, measured by the ratio of the current flowing through the system to the potential difference across it; the reciprocal of resistance. It is measured in reciprocal ohms, mhos, or siemens. Symbol GConductivity : It is defined as the ratio of the current density in the wire to the electric field which brings above the flow of electron in the wire. It is reciprocal of the resistivity of the metalic wire. SI unit is siemens per meter (S/m). | |

Please tell me that what happens when go at the negative to the speed of light? |
| Answer» Understand what “negative” speed means. It just means that you are going backwards (in a certain defined frame)in space and not in time.If you are a F1 racer, when the race starts, you accelerate negatively and achieve a negative speed and start going backwards in the racetrack while everybody is going forwards.That being said, you cannot anyway travel at the speed of light, forwards or backwards in space. | |

Explain evolution of eye in planaria |
| Answer» Planaria is the first animal which shows ‘eye’ like structure. The dark spots on planaria are light sensitive spots but a planaria cannot distinguish between two different objects. Eyes of insects are compound eyes which are made up of thousands of optical surfaces. Eyes of higher animals are simple eyes which are composed of a single lens. Most of the animals cannot differentiate among colours. Depth perception is also weak in many animals. | |
