67054.	What are affrent and efferent artrioles
Answer» The afferent and efferent arterioles are present in the kidney. Afferent arteriole is a branch of renal vein that brings blood containing nitrogenous wastes to the nephrons for purification. It branches into a number of capillaries (glomeruli) and joins back to form efferent arteriole. Efferent arteriole is a branch of renal artery that takes the purified blood back to the heart from where it is pumped back to the tissues.Normally, the afferent arteriole is broader and of a larger diameter than the efferent arteriole to enable the malpighian body develop a pressure condition that aids in filtration. Afferent arteriole brings blood to the glomerulus . Efferent arteriole takes blood away from the glomerulus.

67077.	What is the parallel combination write its mathematical expression
Answer» Brainly.in1Primary SchoolScience 5 pointsDerive the formula of series and parallel resistancesAsk for details Follow Report by GowthamiChowdary 28.12.2017AnswersAbcdefghijklmnopaAbcdefghijklmnopa ExpertDifference between series connection and parallel connection of resistors :In series connection :1. The current is same in every resistor.2. The voltage across any resistor is directly proportional to the resistance of that resistor in the circuit.3. The total resistance in the circuit is equal to the sum of the individual resistances, including the internal resistance of a cell if any.4. The total resistance in the series circuit is more than the greater one in the circuit.In parallel connection :1. The potential difference across each resistance is the same and is equal to the applied potential difference.2. The total current through the parallel combination is the sum of the individual currents through the various resistors.3. The reciprocal of the total resistance pf the parallel combination is equal to the sum of the reciprocals of the individual resistances.4. The total resistance in parallel combination is less than the least resistance used in the circuit. Proof for the above differences is given below :For series connectioFigure shows the 3 resistances R1, R2 and R3 connected in series. When a potential difference V is applied across the combination, the same current I flows through each resistance.By Ohm\'s law, the potential drops across the three resistances are :V1 = I R1, V2 = I R2, V3 = I R3If Rs is the equivalent resistance of the series combination, then we must haveV = I R sBut V = sum of the potential drops across the individual resistances\u200bor V = V1 + V2 + V3or I Rs = I R1 + I R2 + I R3\u200bor Rs = R1 + R2 + R3For parallel combinationI1 = V/R1, I2= V/R2, I3 = V/R3\u200bIf Rp is the resistance of teh parallel combination, then we must haveI = V/Rp\u200bBut, I = I1+ I2 + I3\u200bor V/Rp = V/R1+ V/R2 + V/R3or 1/Rp = 1/R1 + 1/R2 + 1/R3 a1/a2=b1/b2=c1/c2

67078.	What is reflex action and reflex arc

67081.	What is genetic drift , speciation and natural selection?
Answer» Genetic driftIt is the random change in gene frequency occuring by chance irrespective of being beneficial or harmful.SpeciationFormation of new species from an existing one due isolation of section of its population.it can occur by following methods:1) geographical barrier2) mutation3)natural selection4)genetic drift.Natural selectionIt brings out improve adaptive relation between the oragnism and the environment by favouring the reproduction and survival of those who are found more suited to the given environmentHope it helps uuu.....♥️♥️

67084.	What ia rheostat.
Answer» \tRheostat is an electric device used as a variable resistance, like\xa0the regulator of the fan.\tIt is used to change the electric resistance in the electric circuit.\tUsually Rheostat consists\xa0of a coil of wire with a terminal at one end and a sliding contact that moves along the coil to tap off the current.\tWe can change the resistance by changing the position of contact of the sliding contact that moves along the coil to tap off the current.
