Answer : 2. "Rs. 830"
Explanation :
Answer: B) Rs. 830 Explanation: Let the total amount in the partnership be 'x'.Then A's share = x/3B's share = x/4C's share = x/5D's share = x - (x/3 + x/4 +x/5) = 13x/60 A : B : C : D = x/3 : x/4 : x/5 : 13x/60 = 20 : 15 : 12 : 13 A's share in the profit of Rs. 2490 = 20 (2490/60) = Rs. 830.

Answer : 1. "long, double chains of nucleic acids."
Explanation :
Answer: A) long, double chains of nucleic acids. Explanation: Gene is a segment of chromosomal DNA or┬аa sequence of DNA or RNA that codes for a molecule that has a function. It is the basic physical and functional unit of heredity. ┬а As genes are made up of DNA it impies that they are long, double chains of nucleic acids as DNA is made of nucleic acids.

Answer : 1. "Stratification"
Explanation :
Answer: A) Stratification Explanation: Stratification as actually the settling down of sediments with different properties to form layers/strata over years. Stratification especially occurs on the bed of water bodies such as oceans. ┬а Stratified sedimentary rocks are used to study the ecological conditions over previous years/eras. ┬а ┬а The other choices like┬аWindstorms,┬аGlacial Ice and┬аStream water are mediums which sediments are transported.

Answer : 1. "the existence of unpaired electrons in the valence shell"
Explanation :
Answer: A) the existence of unpaired electrons in the valence shell Explanation: When atoms react they do so in order to reach the lowest energy, which is the most stable. The electrons orbitals will overlap in the way that reduces the energy the most. Orbitals of similar energy will produce the greatest stabilisation.The answer you gave isn't the whole story, it depends what species is reacting with what. The effective nuclear charge on the atom will affect the energy of the valance electrons. ┬а Hence, the reactivity of an atom arises from┬аthe existence of unpaired electrons in the valence shell.
