Answer:
By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.Changes (mutations) to genes can result in changes to proteins, which can affect the structures and functions of the organism and thereby change traits. Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited.
Explanation:
Mass defect and binding energy are related as
ΔE = Δmc^2
Where
ΔE = binding energy
Δm = mass defect
c = speed of light
given
mass defect = 3.09x 10-27 kg
We know that speed of light = 3 X 10^8 m /s
ΔE = 3.09x 10-27 kg (3 X 10^8 m /s)^2 = 2.781 X 10^-10 J / Kg

<u>Answer:</u> The temperature of the solution in Kelvins is 422.356 K
<u>Explanation:</u>
Temperature is defined as the measure of coldness or hotness of a body. It also determines the average kinetic energy of the particles in a body.
This term is expressed in degree Celsius, degree Fahrenheit and Kelvins. All these units are interchangeable.
The S.I unit of temperature is Kelvins.
We are given:
Temperature of a solution = ![149.206^oC](https://tex.z-dn.net/?f=149.206%5EoC)
Conversion used to convert degree Celsius and Kelvins is:
![T(K)=[273.15+T(^oC)]](https://tex.z-dn.net/?f=T%28K%29%3D%5B273.15%2BT%28%5EoC%29%5D)
![T(K)=273.15+149.206\\T(K)=422.356K](https://tex.z-dn.net/?f=T%28K%29%3D273.15%2B149.206%5C%5CT%28K%29%3D422.356K)
Hence, the temperature of the solution in Kelvins is 422.356 K
Answer:
![t=23.5min](https://tex.z-dn.net/?f=t%3D23.5min)
Explanation:
Hello,
In this case, since the rate equation turns out as shown below due to the first-order kinetics:
![\frac{dC_A}{dt}=-kC_A](https://tex.z-dn.net/?f=%5Cfrac%7BdC_A%7D%7Bdt%7D%3D-kC_A)
Its integration results:
![\int\limits^{C_A}_{C_A^0} { \frac{dC_A}{C_A}} \,=-k\int\limits^t_0 {} \, dt\\ln(\frac{C_A}{C_A^0})=-kt](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7BC_A%7D_%7BC_A%5E0%7D%20%7B%20%5Cfrac%7BdC_A%7D%7BC_A%7D%7D%20%5C%2C%3D-k%5Cint%5Climits%5Et_0%20%7B%7D%20%5C%2C%20dt%5C%5Cln%28%5Cfrac%7BC_A%7D%7BC_A%5E0%7D%29%3D-kt)
However, the rate constant is computed by considering the given half-life time as follows:
![k=\frac{ln(2)}{t_{1/2}}=\frac{ln(2)}{2.42x10^3s}=2.86x10^{-4}s^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7Bln%282%29%7D%7Bt_%7B1%2F2%7D%7D%3D%5Cfrac%7Bln%282%29%7D%7B2.42x10%5E3s%7D%3D2.86x10%5E%7B-4%7Ds%5E%7B-1%7D)
In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:
![C_A=0.668C_A^0](https://tex.z-dn.net/?f=C_A%3D0.668C_A%5E0)
![ln(\frac{0.668C_A^0}{C_A^0})=-kt](https://tex.z-dn.net/?f=ln%28%5Cfrac%7B0.668C_A%5E0%7D%7BC_A%5E0%7D%29%3D-kt)
![t=\frac{-ln(0.668)}{2.86x10^{-4}s^1}=1408.3s*\frac{1min}{60s} \\t=23.5min](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B-ln%280.668%29%7D%7B2.86x10%5E%7B-4%7Ds%5E1%7D%3D1408.3s%2A%5Cfrac%7B1min%7D%7B60s%7D%20%5C%5Ct%3D23.5min)
Best regards.
For this question, we can use relations for pH and pOH. We calculate as follows:
pOH = -log [OH-]
pOH = -log [<span>1.83x10^-7 M]
pOH = 6.74
pH + pOH = 14
pH = 14 - 6.74
pH = 7.26
pH = -log [H3O+]
7.26 = -log[H3O+]
[H3O+] = 5.46 x 10^-8 M
Hope this answers the question. Have a nice day.</span>
