Standard temperature and pressure (STP) is defined as 273 K and 1 atm.

The standard unit of time in the SI system is the second (s).

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

DNA is described as a double helix, consisting of two strands that wind around each other.

DNA is composed of nucleotides, which include a sugar, phosphate, and nitrogenous base.

The sum of the angles in a triangle is always 180 degrees.

The sum of the coefficients is (2 + 3)^4 = 5^4 = 625.

The sum of the coefficients is found by substituting x=1. So, (1 + 2)^5 = 3^5 = 243.

(1 + 2i) + (3 - 4i) = (1 + 3) + (2 - 4)i = 4 - 2i.

(3 + 2i) + (1 - 4i) = (3 + 1) + (2 - 4)i = 4 - 2i.

The sum of the roots is given by -b/a = 4/2 = 2.

The sum of the roots is given by -b/a = -12/3 = -4.

The symbol for Gold is Au.

To convert Kelvin to Celsius, use the formula: °C = K - 273. Therefore, 273 K - 273 = 0°C.

Temperature in Kelvin (K) = Temperature in Celsius (°C) + 273.15 = 25 + 273.15 = 298.15 K.

The term containing x^2 is given by C(6,2) * (3x)^2 * (-4)^(6-2) = 15 * 9 * 256 = -1440.

The term containing x^2 is given by C(6,2) * (4)^4 * (x)^2 = 15 * 256 * x^2 = 3840.

The term containing x^5 occurs when k = 5. Using the binomial theorem, the term is C(6,5) * (2x)^5 * 3^1 = 6 * 32 * 3 = 576.

The term containing x^5 occurs when k = 5. Using the binomial theorem, the term is C(8,5) * (2x)^5 * (-3)^3 = 56 * 32 * (-27) = -48384.

A bisexual flower contains both male (stamens) and female (pistils) reproductive structures.

A bisexual flower contains both male (stamens) and female (pistils) reproductive structures.

A saturated solution is one that contains the maximum amount of solute that can dissolve at a specific temperature.

An organism with two identical alleles for a trait is called homozygous.

The genetic makeup of an organism is referred to as its genotype.

Endemic species are those that are found nowhere else on Earth and are often vulnerable to extinction.

Endemic species are those that are found only in a specific geographic area.

Excitability refers to the ability of a muscle to respond to a stimulus, such as a nerve impulse.

Excitability refers to the ability of muscles to respond to stimuli, such as nerve impulses.

Inflorescence refers to the arrangement of flowers on a stem.

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.
