Urine is a liquid by-product of metabolism in the bodies of many animals, including humans. It is expelled from the kidneys and flows through the ureters to the urinary bladder, from which it is soon excreted from the body through the urethra during urination.

Charge -Radius Ratio: It is a measuring technique which describes the metallic character of elements.
According to charge/radius ratio, the element having c/r less than 7.0 are called as metallic, ane those elements which have charge /radius ratio greater than 7.0 are called as non-metallic, whereas it has been seen that the element which has charge/radius ratio slightly greater than 7.0 are called as semi-metals or more commonly called as semi -conductor.

Let original radius = r
Original temperature = T
Original power radiated = P
According to Stefan-Boltzmann Law, Power radiated by black body = {tex}P = σAT^4=\sigma 4\pi r^2T^4{/tex}
{tex}=> 500 = 4\sigma \pi r^2T^4{/tex}
New radius = {tex}r\over 2{/tex}
New temperature = 2T
New power P` = {tex}4\sigma \pi \times {r^2\over 4}\times 16T^4{/tex}
{tex}4\times (4\sigma \pi r^2T^4)= 4\times P{/tex}{tex}= 4\times 450= 1800{/tex}
Power becomes 1800 W

x²+y²=(sinA+cosA) ² +(sinA-cosA) ²
= 2
OR,
x+y=k sinA, x-y=k cosA
x²+y²=1/2(k²sin²A + k²cos²A)
= 1/2 (k²(sin²A + cos²A))
= 1/2 *k²
= k²/2

Mass of hydrogen =10g
No. of moles of hydrogen =w/M= 10g/2gmol-1 =5mol
Mass of oxygen =64g
Moles of oxygen = w/M = 64g /32gmol-1 = 2mol
According to the reaction, 2H2 + O2 ------------ 2 H2O
Hence, for 2 moles of oxygen, 4 moles of hydrogen are required and 4 moles of water is produced. Here oxygen is the limiting reagent

Decomposition can be aerobic or anaerobic. Two broad categories of microorganisms consume and decompose organic matter: those that need air (aerobic) and those that don't (anaerobic).
Dr Pathikrt Banerjee 8 years, 5 months ago
Can be aerobic or anaerobic. Increases in absence of oxygen.

Partial regulators change their body temperature to certain level of ambient temperature but if the temperature goes on increasing they can maintain a steady temperature.
ex-shrew (Sorex araneus), ground squirrel (Spermophilus tridecemlineatus).No because of small size they are partial regulators.

A pathogen is defined as anything that is able to cause a disease within a host. As such, a pathogen can be one of many types of microorganisms or particles such as bacteria, fungi, viruses, prions and parasites.
As such, we can say that all parasites causing a disease in human are pathogens, but it is incorrect to say that all pathogens are parasites, as they can be other types of microorganisms, viruses or prions. Following this definition, it is also incorrect to say that all parasites are pathogens as some are able to live as free-living organisms.
