Explanation A triangle is called a right-angled triangle when it has an angle equal to 90 degrees. Otherwise, it will not be a right-angled triangle. **** all  four sides  are of equal length ( equilateral ), and all f our angle s are right angles.  A triangle that has  no equal sides  and  no equal angles  is  known  as  a Scalene Triangle while  if  two sides o f a triangle are of  equal length , then it is  called .  Isosceles triangle Sh5-9-2023

Explanation Emmanuel Macron  as president,  Édouard Philippe  became French Prime Minister on 15 May 2017. The current French Prime Minister is   Elisabeth Borne  since May 2022 . Check updated status https://en.wikipedia.org/wiki/Prime_Minister_of_France

Explanation 0.2 × 0.02 = 0.004 Explanation The cell is the smallest unit of life . Cells are called ‘ structural ’ and ‘ functional ’ units for a reason. Cells are made of molecules which are in turn made up of atoms . “ Cell is the unit of LIFE ” is that a cell is the smallest living entity in a living system. Explanation The backbone of DNA consists of alternating deoxyribose sugar and phosphate groups , linked by phosphodiester bonds. Key Information : Sugar-Phosphate Backbone : Provides structural stability to the DNA double helix. Directionality: 5’ (phosphate) to 3’ (sugar) orientation. Nitrogenous Bases (A, T, C, G) : Attached to the sugar but not part of the backbone. Form hydrogen bonds to create base pairs (A-T, C-G). Explanation Nucleic acids (DNA/RNA) are present in: Nucleus : Contains genomic DNA (eukaryotic cells). Mitochondria : Have their own mtDNA (vital for energy production). Chloroplasts (in plants/algae): Contain cpDNA for photosynthesis-related functions. Explanation The modern periodic table is arranged by increasing atomic number (number of protons). This arrangement resolves inconsistencies in earlier tables and groups elements with similar properties together. Explanation ATP (Adenosine Triphosphate) is called the energy currency of the cell because it stores and provides energy for cellular activities. It releases energy when converted to ADP (Adenosine Diphosphate), which is then recycled back into ATP through cellular respiration. Explanation Boyle’s Law describes the inverse relationship between the pressure (P) and volume (V) of a given mass of gas at constant temperature (isothermal conditions): P ∝ 1/V or PV = constant Key Points : Conditions : Fixed mass and temperature (no chemical reactions). Example : Compressing a syringe (volume ↓ → pressure ↑). Explanation The increase in length (or volume) of solids when heated is specifically called thermal expansion . Key Information : Thermal Expansion : Occurs due to increased atomic vibrations with temperature. Linear expansion : Change in length (e.g., railroad tracks expanding in summer). Volumetric expansion : Change in 3D dimensions (e.g., mercury in thermometers). Explanation Methane is the simplest of saturated hydrocarbons with a chemical formula CH4. It consists of four hydrogen atoms and one carbon atom. It is the simplest alkane . Explanation Cholesterol is a vital precursor in the biosynthesis of: Vitamin D : Cholesterol converts to 7-dehydrocholesterol in the skin, which forms vitamin D₃ under UV light. Steroid Hormones : Cholesterol is the backbone for : Sex hormones (testosterone, estrogen, progesterone). Adrenal hormones (cortisol, aldosterone).
