The backbone or the vertebral column is a long, bony, rodâlike structure, which extends from the base of the skull to the lower back. The animals which possess the backbone are called vertebrates and the ones which do not possess it are called invertebrates. Ant, spider, octopus, amoeba and starfish, are all invertebrates.So, the answer is B.
Amoeba does not lay eggs. It is an unicellular organism which divide by binary fission.

Here, the answer is D.
Black residue is obtained in test tubes I and III i.e., iron gets displaced in test tubes I and III. Therefore, metals P and R should be more reactive than iron.
No change is observed in test tubes II and IV hence, metals Q and S should be less reactive than iron.
Ans 2:
Class : Class 5
Since the residue obtained was black in colour and we know that only Zinc and Copper on reacting with Iron give a black residue hence the answer is Option D

Here, the answer is D.
The method used to extract metals from the ore in which they are found depends on their reactivity. For example, reactive metals such as aluminium are extracted by electrolysis, while a less-reactive metal such as iron may be extracted by reduction with carbon or carbon monoxide.
The metals low in the reactive series are very less reactive. The oxides of such metals can be reduced to metals by heating alone e.g. mercury is obtained from its ore, cinnabar (HgS), by the process of heating.
Metals like iron, zinc, lead etc. occur as sulphides or carbonates in nature. First the ore is converted into its oxide form This is done by either roasting or by calcination. The metal oxide is reduced to metal by using suitable reducing agent such as Carbon.

IF [I] WILL BE TRANSPARENT ,AS WE KNOW THAT THE MATERIALS WHICH ALLOW LIGHT TO PASS THROUGH THEM ARE CALLED TRANSPARENT SO IF WE CUT OUT A SQUARE TRANSPARENT SHEET FROM A ROLL OF TRANSPARENT ,SURELY THE LIGHT PATCH WILL PASS THROUGH[II]THEN THE [II] MATERIAL SHOULD BE SOMETING WHICH CAN NOT ALLOW LIGHT TO PASS TROUGH IT IT SHOULD BE OPAQUE AND THE LAST SQUARE[III] CAN BE MADE OUT FROM ANY MATERIAL,THUS IT WILL NOT CHANGE THE ANSWER.SO WE CONCLUDE THE CORRECT ANSWER IS C
Ans 7:
Class : Class 6
its c as transparent object 1 will allow light ti pass. opaque object 2 wont allow anything to pass and will make a patch of light and the last could be anything
