Answer : 1. "8010"
Explanation :
Answer: A) 8010 Explanation: (2000 + 3)(2000 + 4) - (2000 + 1)(2000 + 2) = ? Since (2000 x 2000) - (2000 x 2000) is equal to zero. ?= (8000 + 6000 + 12) - (4000 + 2000 + 2) => 14012 - 6002 = 8010.

Answer : 3. "Mitochondria"
Explanation :
Answer: C) Mitochondria Explanation: Cellular respiration is the multi-step process that creates energy from nutrients and food molecules. It begins in the cytoplasm of the cell, with the mitochondria functioning as the main organelle where the rest of the process continues and finishes. During respiration, glycolysis occurs in the cytoplasm of the cell.

Answer : 2. "serving as the interface between the other spheres"
Explanation :
Answer: B) serving as the interface between the other spheres Explanation: The geosphere is the earth's solid rock or rigid outer layer known as the crust. Without the geosphere it would not be possible for humans to live on the planet. The function of the geosphere serving as the interface between the other spheres.

Answer : 1. "a nonpolar molecule with polar bonds"
Explanation :
Answer: A) a nonpolar molecule with polar bonds Explanation: The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is cancelled by the symmetric tetrahedral shape. Hence, making the net dipole as zero and molecule as non-polar. When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes polar.

Answer : 1. "7/12"
Explanation :
Answer: A) 7/12 स्पष्टीकरण: यहाँ यह बताने के लिए कि दिए गए विकल्पों में से कौन-सी भिन्न बड़ी है, वह भिन्न जिसमें समान हर वाला बड़ा अंश हो या समान अंश वाला छोटा हर। दिए गए विकल्पों में से बड़ी भिन्न ज्ञात करने के लिए, सभी हरों का LCM ज्ञात करके विकल्पों के लिए हरों को समान बनाएं। 7/12, 9/16, 13/20, 32/80 अब, 12, 16, 20, 80 = 240 का एलसीएम। फिर, 140/240, 135/240, 156/240, 96/240 यहां 156240> 140240 > 135240 > 96240=> 1320 > 712 > 916 > 3280 इसलिए, सबसे बड़ी भिन्न = 13/20।

Answer : 2. "more quickly than simple interest"
Explanation :
Answer: B) more quickly than simple interest Explanation: Compounding interest means interest accrues on the interest charged and the principal amount each period the interest is charged. Compound interest is calculated by multiplying the principal amount by one plus the annual interest rate raised to the number of compound periods minus one.The total initial amount of the loan is then subtracted from the resulting value. The formula for calculating compound interest is: [P (1 + i)n] – P = P [(1 + i)n – 1] (Where P = Principal, i = nominal annual interest rate in percentage terms, and n = number of compounding periods.) Take a three-year loan of Rs. 10,000 at an interest rate of 5% that compounds annually. What would be the amount of interest? In this case, it would be: Rs. 10,000 [(1 + 0.05)3] – 1 = 10,000 [1.157625 – 1] = Rs. 1,576.25. How it grows ::
Q: Which two atoms form an ionic bond? 2422 05b5cc604e4d2b4197774b4b7

Answer :
Explanation :
Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another.. This bond generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion. Example :: One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
