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]

Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.

In chickens, comb shape is determined by genes at two loci (R, r and P, p). A walnut comb is produced when at least one dominant gene R is present at one locus and at least one dominant gene P is present at a second locus (genotype R_ P_). A rose comb is produced when at least one dominant gene is present at the first locus and two recessive genes are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive genes are present at the first locus and at least one dominant gene is present at the second (genotype rr P_). If two recessive genes are present at the first and the second locus (rr pp), a single comb is produced. Give genotypes for comb shape of the parents in the following cross: Rose crossed with pea produces 20 walnut offspring.
a. RR PP × rr pp
b. RR Pp × rr pp
c. Rr PP × rr pp
d. Rr Pp × rr pp
e. Rr pp × rr pp
Answer:
in the obtained options, there is no dominant gene for the crossed pairs, therefore, no answer would be correct, however, when assigning a dominant character to the P gene, the correct answer would be:
E. Rr pp *rrPp
Explanation:
According to the information obtained we deduce:
Comb shape is produced by R and P
Comb of walnuts with an R or a P
Pink comb: 1 dominant P and R at the first locus and 2 recessive at the next locus
Pea comb: 2 recessive at the start and one dominant in the next position
1 single comb: 2 recessive at both loci
Rr pp × rr Pp will produce from the interbreeding: 2 walnuts, 1 single and 1 pea offspring.
We deduce that for the pink comb the genotype is: Rrpp
and for the pea comb it is rrPp
Rr pp × rr Pp generates crosslinks containing RrPp, rrPp, rrpp as children in a 2: 1: 1 ratio.

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.

How is electricity generated in the simulation?
Answer:
(LONG RESPONSE!)
In this work, several simulations and analyses are carried out to investigate the feasibility of generating electricity from underwater sea currents at Istanbul Bosphorus Strait. Bosphorus is a natural canal which forms a border between Europe and Asia by connecting Black Sea and Marmara Sea. The differences in elevation and salinity ratios between these two seas cause strong marine currents. Depending on the morphology of the canal the speed of the flow varies and at some specific locations the energy intensity reaches to sufficient levels where electricity generation by marine current turbines becomes economically feasible.
In this study, several simulations are performed for a 10 MW marine turbine farm/cluster whose location is selected by taking into account several factors such as the canal morphology, current speed and passage of vessels. 360 different simulations are performed for 15 different virtual sea states. Similarly, 8 different configurations are analyzed in order to find the optimum spacing between the turbines. Considering the spatial variations in the current speed within the selected region, the analyses are performed for three different flow speeds corresponding to ±10% change in the average value. For each simulation the annual energy yield and cluster efficiency are calculated.

"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "
Answer:
... areas labeled both red and green.
Explanation:
The spots that show up as yellow correspond to areas labeled both red and green.
__
The effect of combining images will depend on the method used to create the combination. There are many possibilities when combining color images.
When mixing red and green light, yellow light is produced. When mixing red and green pigment, brown pigment is produced. When mixing digital representations of red and green, the effect depends on the individual representations, the method of mixing, and the interpretation of the mixed result.
__
Given the way the question is worded, we assume that yellow is produced by a combination of red and green appearing in the same area of the images. That is, ...
The spots that show up as yellow correspond to areas labeled both red and green.

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.

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.
