Answer : Option C) Mammalia
Explanation : The most specific classification that puts humans in the same category of yapok is mammalia. As humans are also mammals which feeds on their young ones with milk, yapok also does the same. This characteristics makes them similar.
As from the definition of mammal, it is any of a class (Mammalia) which has warm-blood mostly higher vertebrates like placentals, marsupials, or monotremes which are seen to nourish their young with milk secreted by mammary glands, and they have the skin which is usually more or less covered with hair, and it also include humans.
Answer:
(1) The outermost shell should have Eight electrons to complete or called as octet and attain stability.
(2) Hydrogen and Chlorine share Electrons with each other and form Covalent bonding.
(3) Hydrogen forms an octet by obtaining an electron, and Helium is the only element that has an octet with two electrons.
(4) The octet rule states that an atom should attain eight electrons in the outermost shell to get stability, However we have exceptional like Hydrogen and helium.
(5) In Ionic bond there is a formation of Ions of the elements in a compound, like in NaCl there will be Na+ and Cl-.
(6) While in Covalent bond there is sharing of electron between the atoms included like O2.
(7) In ionic bond there is an electrostatic force of attraction while in Covalent bond the is a mutual sharing of electrons.
