Polygenic risk scores are computed by summing the risk alleles associated with each person's chosen phenotype and weighting them according to the estimated effect size of the strongest GWAS.
Explain about the Polygenic traits?A trait is said to be polygenic if it is controlled by multiple genes rather than just one, and each of these genes will have a large number of alleles.
A trait influenced by two or more genes is referred to as a polygenic trait. Examples of such traits include height and skin tone. Polygenic traits do not inherit according to Mendelian principles since numerous genes are involved. The term "multifactorial" refers to features that are largely polygenic but also impacted by the environment.
Height, skin color, and eye color are three examples of human features that are polygenic. Many different genes control these features.

In the hydrogenation of alcohol, Ethanol is the reducing agent and it loses electron.
Alcohol hydrogenase transform ethanol to Acetaldehyde. This known as carcinogen. In this Acetaldehyde is more toxic compound. Alcohol dehydrogenases catalyze the oxidation of primary and secondary alcohols to the corresponding aldehyde or ketone by the transfer of a hydride anion to NAD+ with release of a proton.
Ethanol + NAD^+ ---> acetaldehyde + NADH + H^+
The half reactions are:
Ethanol --------->Acetaldehyde + 2H^+ + 2e (oxidation)
NAD+ + 2H+ + 2e- ------->NADH + H^+ (Reduction)
Ethanol is oxidized to acetaldehyde, because it loses e- .NAD+ is reduced to NADH, because it gain of e− . NAD is the oxidizing agent. Oxidizing agent gains e− and therefore reduced during reaction.

1228 gram of oxygen gas is required to complete the combustion of 702g of C8H18 .
This involves the combustion reaction. A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. The given reaction is the combustion of gasoline which is a hydrocarbon. On combustion hydrocarbons produce carbon dioxide and water.
C8H18 + 12.5 O2 -----> 8 CO2 + 9 H2O
From the balanced equation it is clear that 1mole of require 12.5 moles of oxygen for complete combustion.
Molar mass of = 114.23 g/mol
number of moles = given mass / molar mass .
Substitute 702 g for given mass and 114.23 g/mol for molar mass.
Hence 702 g of C8H18 have 6.14 moles of C8H181 .
1mole of C8H18 require 12.5 moles of oxygen for complete conversion.
then we have to Calculate the number of moles of oxygen required for the complete combustion of 6.14 moles of C8H18 .
Number of moles of oxygen required ,
( 12.5 * 6.14 ) = 76.65 moles
Therefore, 76.75 moles of oxygen is required for the complete combustion of 702 g of C8H18.
Now Convert 76.75 moles of oxygen into mass.
mass = number of moles / molar mass .
= 76.65 moles / 16 gram/mole
= 1228 g
Substituting 76.75 moles for number of moles and 16 g/mole for molar mass of oxygen we get 1228 g of oxygen .

pH = 9.33418
Let's assume the temperature of the given buffer system is
25 degree C
. Hence, according to the Henderson-Hasselbalch equation, the pH of the given buffer system is calculated using the following expression as shown below:
pH = 14 - pKb (NH3) + log (nNH3) / (nNH3Cl)
where nNH3 and nNH4Cl represent the no. of moles of NH3 and NH4Cl present in the buffer system.
The molar mass of NH4Cl is 53.491 g / mol. so nNH4CL present in 10.70g of mass is calculated
nNH4CL = 10.70 g / 53.491 g/ mol
= 0.2000 mol
nNh3 present in 20 ml 0f 12 m NH3 is calculated
nNH3 = (12 * 20) / 1000 MOL
= 0.24 MOL
pKb (NH3) is calculated
pKb (NH3) = - log(Kb(NH3))
= - log(1.80 * [tex]10^{-5}[/tex])
= 4.745
Hence the pH of the buffer system
pH = 14 - 4.745 + log 0.2400/ 0.2000

Question:
he statements in the tables below are about two different chemical equilibria. the symbols have their usual meaning, for example stands for the standard gibbs free energy of reaction and stands for the equilibrium constant. in each table, there is one statement that is false because it contradicts the other three statements. when you find a false statement, check the box next to it. statement false? statement false?
[tex]\Delta[/tex]G = 0 when a system is in equilibrium. [tex]\Delta[/tex]G<0 if the process is spontaneous.
Why is it called Gibbs free energy?Gibb's free energy is named free energy because it is readily available at all times. If necessary, the reaction can obtain this energy without having to do any effort. The change in Gibb's free energy is the sum of enthalpy and the product of the system's temperature and entropy.The standard change in free energy, or the change in free energy under standard conditions, is denoted as delta-G zero. R represents the gas constant, T represents the temperature in Kelvin, and K represents our equilibrium constant. So, if you use this equation, you're in equilibrium, and delta-G equals zero.The equation for the relationship between Gibbs energy and the equilibrium constant is [tex]\Delta[/tex]Go=RTlnKeq.[tex]\Delta[/tex]G = 0 when a system is in equilibrium. [tex]\Delta[/tex]G<0 if the process is spontaneous.To learn more about Gibbs free energy refer,
