the function y is equal to cosine of x is increasing

the function y is equal to tangent of x is increasing

the function y is equal to sine of x is increasing

separate electrolysis of dilute nacl and concentrated nacl solution using inert electrodes will yield the same product at the anodes

in the electrolysis of cuso4 solution using copper electrodes, the colour of the electrolyte does not change with time

in the electrolysis of cuso4 solution using inert electrodes, ph of the electrolyte increases with time

every dna molecule is distinguished by its sequence of nucleotides

in eukaryotes, dna is present exclusively in the nucleus

SO2 gas may be prepared by heating NA2SO4 solid with concentrated HCL

dna is the genetic material for some viruses

at minimum deviation of light passing through a triangular prism, the angle of deviation equals the angle of the prism

at minimum deviation of light passing through a triangular prism, the angle of incidence equals the angle of the prism

at minimum deviation of light passing through a triangular prism, the angle of incidence on one face equals the angle of refraction at the second face

the equation x squared minus three x minus four is equal to zero has two distinct roots

the equation x squared minus two x plus three is equal to zero has no roots

the equation x squared minus six x plus nine is equal to zero has identical roots

I am a named effect.

I am indeed one of the three closely related effects

We are associated with energy conversion

PH3 gas can in principle be collected in a gas jar by displacement of air.

I am named for one Thomas who rediscovered me after Voltaire

I am the effect in which heat is converted directly into electricity. So who am I?

I am a quadrilateral. My diagonals bisect the vertex angles. My diagonals are perpendicular. My diagonals bisect each other. My diagonals are congruent.

My diagonals bisect each other

My diagonals are congruent

I am relatively small and cute. My central atom has sp3 hybridized orbitals. My shape is ineviably tetrahedral. I am a natural when

I am relatively small and cute

diastole is a phase in the cardiac cycle during which the heart relaxes and allows blood to refill each atrium and each ventricle

My central atom has sp3 hybridized orbitals

My shape is inevitably tetrahedral

I am natural when I am mined

I am a green house gas

I am a small hole behind each eye that opens to the mouth in some fishes. In tadpoles I am the ex current opening.

the period of small amplitude oscillations of a simple pendulum is porportional to the square root of the pendulum length

the period of small amplitude oscillations of a simple pendulum is independent of the mass of the pendulum bulb

the period of small amplitude oscillations of a simple pendulum is independent of the location of the pendulum

diastole is the longer of the two phases and the contraction of the muscles in the heart happens rather quickly

sine inverse of one is equal to cosine inverse of zero

tangent inverse of one is equal to cotangent inverse of one

sine inverse of one over root two is equal to cosine inverse of one over root two

dichotomous keys are most often used for identifying plants and animal species based on their characteristics

the use of dichotomous keys can sometimes experience errors because closely related species may share many of the same characteristics

dichotomous keys can be used to identify an organism by its scientific name

magnesium trioxocarbonate four is insoluble in water but dissolves when co2 gas is bubbled through its suspension in water

lithium, sodium and potassium tarnish easily in air

the hydroxides of lithium, sodium and potassium are all strong bases

an isobaric ideal gas process occurs at constant internal energy

diastole can be divided into two different types. atrial diastole and ventricular diastole as the atria and ventricle stop contacting at slightly different points

an isobaric ideal gas process is represented by a straight horizontal line on a pv diagram

more heat is need for unit temperature change of an ideal gas in an isobaric process than for unit temperature change of an ideal gas in a constant volume process

the linear equation a x plus b y is equal to c is in the intercept form

the linear equation y is equal to m x plus c is in the intercept form

the equation x over a plus y over b is equal to one is in the intercept form

many animals that use open circulatory systems do do have a heart

open circulatory systems are used by arthropods and most molluscs

octopus and squid are considered molluscs that they have evolved closed circulatory systems

esters are known as alkanoic acid derivates because esters and alkanoic acids have the same functional group

in the preparation of esters in the laboratory h3po4 may be used in place of concentrated h2so4 as the acid catalyst

Ultima thule, the most distant object to be visited by a space craft from earth rotates with a period of about sixteen hours.

esters can be hydrolyzed by bases as well as acids

I occur in cartesian geometry. I am a distance. I am a distance from a point to a line. I am the shortest distance from a point to any point on the line. I am given by the length of a perpendicular from the point to the given line. So who am I?

In this round I am going to be presenting you with statements. When you receive a statement, please consider the statement very carefully and let me know whether it's true or false. If you are right, two points. If you are incorrect you lose a precious point. You may choose not to respond in which case that statement becomes available to the two other schools. A school may ring and attempt an answer if
