P(S1) = (2×obs(S1S1) + obs(S1S2))/(2×fish(S1S1)+2×fish(S1S2) +2×fish(S2S2) )
P(S1)= (60+50)/(60+100+40)
P(S1)=0.55
P(S2)= 1-P(S1)
P(S2)= 0.45
Exp(S1S1)= 0.55×0.55×100=30.25
Exp(S1S2)= 2×0.45×0.55×100=49.5
Exp(S2S2)= 0.45×0.45×100=20.25
x²=∑ (Observed-Expected)²/ Expected
= (30-30.25)²/30.25 + (50-49.5)²/49.5+ (20-20.25)²/20.25
= 0.010203
The value at 5% significance level and degree of freedom 1 from table is 3.84. Since x² value is less than value we accept null hypothesis
It takes two generations to achieve Hardy-Weinberg equilibrium if conditions of Hardy-Weinberg are met.
During summer in the Northern Hemisphere,

the Sun rises earlier and sets later than during other seasons.
B.
the Sun appears lower in the sky than during other seasons.
C.
there are fewer hours of visible sunlight each day than during other seasons.
D.
the Sun rises in the Southeast and sets in the Southwest.
Answer:
A
Explanation: In the summertime in the northern hemisphere, the Earth is farther from the Sun because of the ellipse in its orbit, but the angle of the Earth's tilt points the hemisphere towards the Sun, making the days longer. The Sun's angle is also higher during the summer months than the winter months.

Explanation:
A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has
this condition, her doctors take a 16.00 mL sample of her gastric juices and titrate the sample with 3.76 x 10-4 M KOH. The
gastric juice sample required 5.87 mL of the KOH titrant to neutralize it.
Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise
interfere with the titration.
Answer:
pH of the gastric juice
[tex]3.86[/tex]
Explanation:
As we know,
In an acid base titration, the number of milimoles of acid is equal to the number of milimoles of base.
Milimoles [tex]=[/tex] Molarity [tex]*[/tex] Volume
Molarity of gastric juices [tex]*[/tex] Volume of gastric juices [tex]=[/tex] Molarity of KOH [tex]*[/tex] Volume of KOH
Substituting the given values in above equation, we get -
[tex]16 * X = 5.87 * 3.76 * 10^{-4}\\[/tex]
X represents the molarity of gastric juices
[tex]X = \frac{5.87 * 3.76 * 10^{-4}}{16} \\X = 1.379 * 10^{-4}[/tex]
pH of gastric juices is equal to log [tex]1.379 * 10^{-4}[/tex]
[tex]= - log 1.379 * 10^{-4}\\= - [-3.86]\\= 3.86[/tex]

15. Knowing that the genetic code is almost universal, a scientist uses molecular biological methods to insert the human B-globin gene into bacterial cells, hoping the cells will express it and synthesize functional B-globin protein. Instead, the protein produced is non-functional and is found to contain many fewer amino acids than does B-globin made by a eukaryotic cell. Explain why.
Answer:
The genetic information of living organisms is sequenced in DNA, which allows inheritable factors to be transmitted with each replication process. Proteins play a very important role by intervening in their metabolism during the translation and transcription of information. .
eukaryotic and prokaryotic organisms have different evolutionary sequelae that are reflected in the mechanisms they use for DNA translation, such as in the initial stages, lengthening and termination of sequencing, these differences are imparted by the order of the genes, the ribosome and its structural form and the promoter sequences.
In this way we can conclude that although the eukaryotic genes enter into a bacterium, the type of information that they take may arrive incomplete and this may generate subsequent defects for their operation, but there may be processes that guarantee a better transfer of information with the use of genetic engineering and enzyme management to introduce different bacterial genetic expressions with eukaryotic genes.
Eukaryotic cells like humans and prokaryotic cells like bacteria vary in central dogma methods.
The generative data of an organism is stored in the sequenced DNA that gets transferred during the process of replication.
The DNA transcription and translation process in prokaryotes and eukaryotes differ like the steps concerned in the beginning and the termination of the arrays are defined by various sets of genes in both types of organisms.
The promoter, ribosomes and the structural genes make both the organism distinct from each other.
So, when the eukaryotic gene intrudes bacteria may lack some data that can get misinterpreted and the resulted proteins or amino acids will differ.

In the hydrophobic core of a folded protein, there are three alanine and five phenylalanine residues that are buried, and do not interact with water.
Assume:
In solution, waters can take on seven energetically equal states.
Two waters are ordered around each alanine in the unfolded state.
Six waters are ordered around each phenylalanine in the unfolded state.
In the unfolded state, waters are ordered around alanine or phenylalanine residues and can take on only two energetically equal states.
What is the difference in the entropy of the water due to the burying of these residues as the protein folds?
Answer:
The difference In The entropy of The western due to The burying of these residues as the protein folds is 291J/K
Explanation:
According to the data we know that
total water molecule = 2 * number of Ala + 6 * number of phenylalanine
replacing we get
2 * 2 + 6 * 4 = 4 + 24 = 28
total water molecule = 28
next step
S folded = Rln728
we replace the data and we get that
8.31 * 28 * ln7 = 452J • K –1 • mol –1
S unfolded = Rln228
we replace the data and we get that
8.31 * 28 * ln2 = 161J • K –1 • mol –1
∆ S = S folded - S unfolded = 452-161 = 291J / K
The CRISPR/Cas9 system can cleave genomic DNA at sequences other than the desired target, a phenomenon referred to as off-target cleavage. To avoid off-target cleavage, sites targeted for mutation should appear only once in the genome. What is the minimum length of the part of an sgRNA molecule that binds DNA whose base pair sequence would be expected to be unique within the fruit fly genome
Answer:
correct answer: 14
Explanation:
the question is incomplete, so a graph with the complete questionnaire is attached and the requested question is answered
We will start from the exercise requesting the minimum length that a sequence forms with more than 1.4x10ˆ8 permutations
for this we deduce that two base pairs can have:
4 * 4 = 16 permutations
we deduce that 3 base pairs can have:
4 * 4 * 4 = 64 permutations
Thus we multiply successively until we reach that 14 base pairs can obtain: 2.68x10ˆ8 permutations that are random
Thus, the 14bp sequence will be found only once in the genome of the fruit fly.
Biologists notice that a population of ferrets introduced into a reserve begins to show exponential growth. The figures represent the population of the ferrets for the first four years after their introduction. Which set of figures represents the exponential growth of the ferrets? A. 50, 88, 145, 227 B. 50, 92, 90, 95 C. 50, 32, 17, 9 D. 50, 95, 59, 97
Answer:
A. 50, 88, 145, 227
Explanation:
The correct option would be option A.
When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.
In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.

Rice is an important food crop in the the world. Growing rice requires large amounts of water because the roots of rice plants must remain under water. Explain how genes could play a role in helping farmers grow rice using less water. 2 sentences, explain they could do (answerrrr ASAP)
Answer:
Rice plants possesses several traits which allow sthem to grow in large amount of water because standing water helps them to produce air channel known as aerenchyma that connects roots with shoots and transport oxygen to submerged tissues. Standing water also help many weed to grow and rice plants also takes nutrients from them as well.
Genes are responsible for the traits that allow rice plants to grow in large amount of water but if the gene of rice plant is genetically modified with new gene which is resistant to drought, that can allow the rice to grow in less water.
The genetically modified rice plant then do not require large amount of water and can grow easily.

why is the moon white
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
Answer:
The moon is not actually white, it's grey.
Explanation:
What I learned is that what makes it white is the reflection of the sun and the sun makes it glow, that's why it looks white.
And if you focus on the moon when it's not full you'll see the other part of it showing but it looks grey not white, because as I told you it's the suns reflection.
Hope I helped!
Have a good day. =)
