By the principle of Henderson-Hasselbalch equation:

Mass of 1 mole of each of the phosphate salts 1 mole of K₂HPO₄: 0.575 gm

Mass 0.1 M solution of KH₂PO₄ in a 100 ml solution: 0.912 gm

In biological and chemical systems, the Henderson-Hasselbalch equation defines the link between pH as a measure of acidity and the acid dissociation constant (pKa). The equation is particularly useful for calculating the pH of a buffer solution and determining the pH of equilibrium in acid-base processes.

Phosphoric acid pKa's are 2.3, 7.21 and 12.35.

Our required pH is 6.5, so 7.21 will be used.

Hence, mono-potassium dihydrogen phosphate (KH₂PO₄) and dipotassium mono-hydrogen phosphate  (K₂HPO₄) will be used.

Handerson-Hasselbach equation:

pH = pKa + log ([A⁻]/[HA])

Therefore, A⁻ is K₂HPO₄ concentration, and for HA is KH₂PO₄ concentration:

or, 6.5 = 7.21 + log(A⁻/HA)

or, log(A⁻/HA)=-0.71

or, A⁻/HA = 0.49

We know that total salt concentration = 0.1 M

HA+A=0.1

A⁻/HA=0.49

So, HA+0.49 HA=0.1

[HA] = 0.1/1.49 = 0.067M

[A] = 0.1-0.067M = 0.033M

Therefore, the concentration of K₂HPO₄ = 0.033M

and the concentration of KH₂PO₄ = 0.067M

Since, we are preparing 100 ml or 0.1 L  of the solution,

Thus, the weight of K₂HPO₄ = (0.033M x mol.weight)x 0.1 L  

                                               =  (0.033M x 174.2 g/mol)x 0.1 L

                                                = 0.575 g of K₂HPO₄ required for 0.1 L

Similarly, we can calculate for KH₂PO₄:

or, wieght of KH₂PO₄   = (0.067M x mol.weight)x 0.1L  

                                      = (0.067M x 136.086 g/mol)x 0.1L

                                      = 0.912 g of KH₂PO₄ required for 0.1L buffer solution.

Therefore, we need to take 0.575 g of K₂HPO₄ + 0.912 g of KH₂PO₄ and dissolve them in 100 ml water to prepare 100mL of a 0.1M potassium phosphate buffer of pH 6.5.

Answer:

Explanation:

The one that causes low vascular resistance is high blood pressure. The correct option is 1.

Vascular resistance is used to keep organs perfused. A hyper-adrenergic response occurs in certain disease states, such as congestive heart failure, causing an increase in peripheral vascular resistance.

Obesity can increase vascular resistance due to fat deposition within the blood vessel walls. Dehydration can also increase vascular resistance due to decreased blood volume and viscosity.

High blood pressure, on the other hand, has been linked to decreased vascular resistance. This is because increased pressure can cause blood vessel dilation, which reduces friction between blood and vessel walls.

Thus, the correct option is 1.

An example of a dominant trait is the violet-colored flower trait. For this same characteristic (flower color), white-colored flowers are a recessive trait.

Explanation:

In all five cycles of the Polymerase Chain Reaction (PCR) process, the amount of target DNA is amplified or increased exponentially.

The process involves three steps: denaturation, annealing, and extension. During denaturation, the double-stranded DNA template is separated into two single strands.

During annealing, the temperature is lowered, and the primers bind to the complementary sequences on the single-stranded template DNA. During extension, the DNA polymerase extends the primers by adding nucleotides to the 3’ end of the primer, thus synthesizing a new strand of DNA. The process is then repeated for several cycles, with the number of target DNA doubling with each cycle.

b. If A_bb (red) and aaB_ (liver) are mated, all of the offspring will be heterozygous for both traits (AaBb). Therefore, 25% (or 1/4) of the offspring are expected to be black.

c. The genotypes of the two parents can also be determined using a Punnett square. The black male must be homozygous for both the "A" and "B" genes (AABB), and the liver-colored female must be heterozygous for both genes (AaBb).

What is Punnett square?

A Punnett square is a tool used in genetics to predict the possible genotypes and phenotypes of offspring resulting from a cross between two individuals. The Punnett square is a table that shows all possible combinations of alleles from the two parents and the probability of each offspring having a particular genotype.

The Punnett square allows geneticists to determine the probability of an offspring inheriting a particular trait or disease based on the genetic makeup of its parents. It is a useful tool for predicting the outcome of genetic crosses and understanding the patterns of inheritance of traits.

The Watson and Crick double helix model of DNA structure, proposed in 1953, provided a breakthrough understanding of the molecular structure of DNA, which has profound implications for our understanding of genetics, heredity, and molecular biology.

The model explained several key features of DNA:

Double helix structure: The model proposed that DNA consists of two strands that are twisted around each other in a helical fashion, forming a double helix structure. The two strands are held together by hydrogen bonds between complementary nucleotide bases (adenine with thymine, and guanine with cytosine), forming base pairs along the interior of the helix. This explained how DNA can have a stable and structural integrity, while also allowing for the replication and transcription of genetic information.

Complementary base pairing: The model explained how the nucleotide bases in DNA (adenine, thymine, guanine, and cytosine) pair specifically with their complementary bases to form the "rungs" of the DNA ladder. This complementary base pairing mechanism ensures that the genetic information stored in DNA is accurately replicated and transmitted during cell division and protein synthesis.

Antiparallel orientation: The model revealed that the two strands of DNA in the double helix are oriented in an antiparallel manner, meaning they run in opposite directions. This orientation allows for the formation of hydrogen bonds between the complementary base pairs, and it has important implications for DNA replication and transcription processes.

The rectilinear mapping method uses one object as an anchor for all measurements.

What is rectilinear mapping method?

Rectilinear mapping is a type of crime scene mapping method that involves creating a scaled diagram of the scene using a series of straight lines to connect measured points. This method is useful in indoor crime scenes and is often used to create a two-dimensional representation of the scene. The key feature of rectilinear mapping is that it uses a grid system, which helps ensure accuracy in measuring distances and angles. The grid system allows for the creation of a precise and detailed map of the crime scene, which can be used to analyze evidence and reconstruct events.

What are the indoor crime ?

Indoor crimes refer to criminal activities that take place within a building or enclosed space. Examples of indoor crimes include burglary, robbery, theft, assault, homicide, and domestic violence. These types of crimes often occur in residential, commercial, or public buildings such as houses, offices, schools, and hospitals. Indoor crime scenes may require different types of investigation techniques and evidence collection methods compared to outdoor crime scenes due to factors such as limited space, the presence of multiple rooms or levels, and potential contamination from human activity.
