In the lung alveoli, the oxygen partial pressure is about 100 mm of mercury, or 0.13 Atm. If blood was solely composed of a saline solution (lacking any hemoglobin), oxygen equilibrates with the alveolar air to a concentration of about 3 mg/L or 0.093 mm). In oxygen-saturated blood, however, the O2 concentration is about 0.008 M (8 mm).

The pedigree below concerns the autosomal recessive disease phenylketonuria (PKU). The couple marked A and B are contemplating having a baby but are concerned about the baby having PKU. What is the probability of the first child having PKU

Answers

Answer: Hello your question some missing data attached below is the complete question

answer:

P( first child having PKU )  0.25 ≤ x ≤ 0.5

Explanation:

The pedigree father has PKU ( pp ) ( From the top right )

pedigree mother = PP

The possible resultant progeny = Pp  

Resultant progeny marries non-carrier  ( Pp x PP ) = PP , PP, pP, pP

Hence B is either  ; PP ( non carrier ) or Pp ( carrier )

From left

one of the Resultant progeny = pp ( affected ). this simply means pedigree parents where both carriers or sufferers i.e. Pp or pp

Hence A is either ; Pp or pp

The probability of their first child having PKU

= PP x Pp = PP, Pp, PP, Pp ( probability = 0 in this case )

= Pp x Pp = PP, Pp, pP, pp ( probability = 1/4 * 100 = 25% )

= Pp x pp = Pp, Pp, pp, pp ( probability = 2/4 * 100 = 50% )

P( first child having PKU )  0.25 ≤ x ≤ 0.5

lets denote dominant Gene = PP,  recessive Gene = pp

O A. y+ 5 = -3(x - 3)
B. y- 5 = -3(x+3)
C. y + 5 = 3(x+3)
O D. Y-3 - (x+5)

Answers

Answer:

A. y + 5 = -3(x - 3)

Explanation:

Given the following data;

Points on the graph (x1, y1) = (3, -5)

Points on the graph (x2, y2) = (0, 4)

First of all, we would determine the slope of the equation of line;

Mathematically, the slope of a line is given by the formula;

[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]

[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the formula, we have;

[tex] Slope, \ m = \frac {4 - (-5)}{0 - 3} [/tex]

[tex] Slope, \ m = \frac {4 + 5}{0 - 3} [/tex]

[tex] Slope, \ m = \frac {9}{-3} [/tex]

Slope, m = -3

Next, to find the point-slope equation of the line, we would use the following formula;

y - y1 = m(x - x1)

y - (-5) = -3(x - 3)

y + 5 = -3x + 9

y = -3x + 9 - 5

y = -3x + 4 = mx + c

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?

Answers

Answer:

The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).

Explanation:

Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.

In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.

In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..

A scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. What molecule has likely contaminated his mixture?


nucleotide

protein

DNA

RNA

Answers

Answer:

RNA

Explanation:

A ribonucleic acid (RNA) is one of two types of nucleic acid made up of nucleotide subunits. RNA is a single stranded molecule unlike DNA, which is double stranded. The nucleotide unit of nucleic acids is composed of a nitrogenous base (Adenine, Guanine, Cytosine and Thymine/Uracil), a pentose sugar (ribose and deoxyribose) and a phosphate group.

One of the key structural differences between RNA and DNA is that RNA contains URACIL nitrogenous base instead of THYMINE in DNA.

According to this question, a scientist finds that another molecule has contaminated the mixture he is working with in the lab. When he analyzes its chemical structure, he finds that it contains uracil, is single stranded, and contains phosphate. This illustrates that the contaminating molecule is a specific type of nucleic acid called RNA.

Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.

Answers

Answer:

The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.

Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.

Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

c. The mutation is a silent point mutation in a protein-coding sequence.
d. The gene carrying the mutation is known to participate in the cell cycle.

Answers

Answer:

The mutation is a silent point mutation in a protein-coding sequence.

Explanation:

A mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. Mutations can be damaging or beneficial.

There are two types of mutations in cancerous cells:

· Driver mutations, which refer to genetic changes that provide malign cells an adaptative advantage. These mutations drive the cells to tumoral evolution.

· Passenger mutations, also known as neutral mutations, refer to those that do not provide any advantage nor disadvantage to the cancerous cell. These mutations can be between DNI segments where the driver mutations are. Some of these passenger mutations might become driver mutations with time.

b. What is the specific metabolic rate, i.e. the metabolic rate per kilogram of body mass for the following animals?a cow whose mass is 300kg. Give your answer to three significant figures.

Answers

Answer:

Given that:

The scaling of the specific metabolic rate is:

[tex]=\dfrac{P_{metab}}{m}[/tex]

where;

[tex]P_{metab} = 70M_b^{0.75}[/tex]

[tex]=\dfrac{ 70M_b^{0.75}}{m}[/tex]

(a) For a mouse whose mass = 30 g = 0.030 kg

The specific metabolic rate [tex]=\dfrac{ 70*(0.030)^{0.75}}{(0.030)}[/tex]

= 168.197 kg

≅ 168 kg to 3 significant fig.

(a) For a cow whose mass = 300 kg

An adult giraffe (Giraffa camelopardalis) has a heart that lies approximately 2 m below the top of the head when its neck is fully extended. Calculate the minimum diastolic pressure that a giraffe must have (in mm Hg). Hint: what is the absolute minimum blood pressure a giraffe could have at the very top of its head

Answers

Answer:

159.01 mmHg

Explanation:

position of Heart = 2m  below the top of the head  given that the neck is fully extended

Determine the minimum diastolic pressure

Minimum diastolic Pressure = 1060 kg/m^3 * 10 m/s^2 * 2m

                                               = 21200 kg/m^2

convert the value to Pa

21200 kg/m^2 = 21200 Pa

( 1 pa = 0.00750062 mmHg )

Therefore : minimum diastolic pressure = 21200 * 0.00750062 = 159.01 mmHg

The minimum diastolic pressure that a giraffe must have is 150 mmHg

Diastolic Blood pressure

Diastolic Blood pressure is the pressure on the walls of your arteries between heartbeats, that is when the heart is resting.

The minimum diastolic diastolic blood pressure = absolute minimum blood pressure a giraffe could have at the very top of its head.

Pressure formula

P = hpg

where;

P = pressure

h = height difference

p = density

g = acceleration due to gravity

Density of blood = 1000 kg/m^3

h =2.0 m

g = 10 m/s^2

Pressure = 1000 × 2.0 × 10

Pressure = 20000 Pascal or 20 kpa

Converting to mmHg

1 kpa = 7.50 mmHg

20 kpa = 20 × 7.50

Pressure = 150 mmHg

Therefore, the minimum diastolic pressure that a giraffe must have is 150 mmHg
