Answer:
The correct answer is - 1/41,493
Explanation:
Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:
2pq + 2pqF. ( where F is the inbreeding coefficient).
The frequency of the two different hoozygotes in inbred population can be calculated as:
p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.
Given: Frequency of Alkaptonuria (q 2) = 1:500, 000
=> q = 1/707
p = 706/707 ( Approx values)
solution:
Inbreeding coefficient (F) = 1/64
Therefore,
Frequency of Alkaptonuria in second cousins= q 2 + pqF
= 1/500, 000 + (706/707 x 1/707) x (1/64)
= 1/500, 000 + 1/45, 248
= 1/41,493 (approx)
Hereditary fructose intolerance is a genetic condition caused by a variant in the ALDOB gene, which is critical for fructose metabolism. Infants with this condition do not initially display symptoms, but as they are transitioned from breast milk or formula to solid foods, in particular fruit-based foods, they begin to display symptoms, which include vomiting, diarrhea, and low blood sugar. Individuals who do not consume fructose do not display these symptoms. Which of the following describes this condition?
a. It is incompletely penetrant, due to environmental factors.
b. It has variable expressivity, due to environmental factors.incorrect
c. It is incompletely penetrant, due to genetic factors.
d. It has variable expressivity, due to genetic factors.
It has variable expressivity due to the environmental factors.
The variation in expressivity occurs due to the environmental factors of that individual. Expressivity describes the differences observed in the phenotype between two individuals that belongs to same genotype.
In the condition, when the patient is allowed to consume the fructose based food, so it expresses the change in its body due to no tolerance against fructose so we can conclude that the change occurs due to environment not due to genetics.

An unknown solution has a pH of 7.1. Which of these chemicals is likely to increase the pH the most when added to the solution?
HF
KOH
NH3
HNO3
Answer:
It is most likely KOH
Explanation:
NH3 is classified as a weak base so I'd suspect that to be incorrect although it does have a higher pH
The chemical that is likely to increase the pH the most when added to the solution is KOH. The correct option is B.
What is pH?
pH is the scale for the measurement of acidity and the basicity of any solution. pH is a scale from 1 to 14. The lowest pH will be highly acidic and the highest pH will be the highest basic.
The lowest the pH, it will donate the highest hydronium ions, and with the highest pH, it will dissociate completely into the solution. KOH dissociates completely into ions.
KOH or potassium hydroxide is a strong base. When the base is added to a solution, it increases its basicity. So it will increase the pH of the solution. All others are acids that will lower the pH of the solution.
Thus, the correct option is B. KOH.

Which of the following processes
describes a cell undergoing exocytosis?
A. cell eating
B. diffusion
C. removing water and waste
D. moving molecules along a concentration gradient
Answer:
C. removing water and waste
Explanation:
Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.
Hope this helps
Answer:
[tex]\boxed {\boxed {\sf C. \ Removing \ water \ and \ waste}}[/tex]
Explanation:
We are asked to find a description for a cell undergoing exocytosis. First, let's define the process.
Exocytosis is a type of active transport, so ATP or energy is required to initiate and complete the process.
This process moves substances from the inside of a cell to the outside. Molecules are packaged into vesicles. The vesicle moves to the cell membrane and attaches. The vesicle fuses with the membrane and the molecules inside the vesicle are released.
Essentially, substances are removed from the cell. This is especially useful because it can rid the cell of any waste or excess water. Therefore, the correct answer is choice C.

TRANSFER RNA (tRNA):
Transfer RNA or commonly known as tRNA is a form of RNA that perform two major functions during the process of translation in the ribosome.Attaching to and reading mRNA sequence using its anticodons. Carrying of corresponding amino acid to the polypeptide chain. The tRNA posseses a group of three nucleotide sequence called ANTICODON. These anticodons are complementary to the mRNA codon sequence. tRNA uses its anticodon to bind and read the mRNA sequence. In the RNA; Adenine binds to Uracil (U) while Cytosine (C) binds to Guanine (G). Hence, if the sequence of bases on the mRNA codon is AUU, the sequence of bases that would be on the anticodon of the tRNA is UAA.Learn more: https://brainly.com/question/21312423?referrer=searchResults

Fill in the bottom line of DNA with the complementary base pair:
Answer: ACCTGATCGTAGCT
Explanation:
Keep in mind that in DNA replication, the matching base pairs are A and T (adenine and thymine) and C and G (Cytosine and Guanine). This means that for DNA complementary strands, A's can ONLY bind with T's and C's can only bind with G's , and vice versa. So, your answer for the picture you have given is ACCTGATCGTAGCT

Anaerobic respiration of yeast produces ethanol and carbon dioxide, which can be experimentally tested by determining the rate of CO2 production in a closed system.
What is anaerobic respiration?Anaerobic respiration is a series of chemical reactions by which certain organisms can produce energy (ATP) in absence of oxygen.
Anaerobic respiration is useful in experimental settings to determine the survival rate of yeast, which can be determined by measuring the concentration of products of this process.
The experimental procedure requires the use of a closed system to determine the rate of change between reactants (glucose) and products (ethanol + carbon dioxide).
In conclusion, Anaerobic respiration can be experimentally tested by determining the rate of CO2 production.

Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Describe the purpose of mitosis.
2. Describe what is happening in each stage and what each stage looks like:
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Answer:
To acquire growth and to replace worn out and defected cells.
Explanation:
The main purpose of mitosis is to acquire growth and to replace worn out and defected cells.
In prophase, the chromatin condenses which is present in the nucleus of the cell.
Prometaphase is the stage where the nuclear membrane breaks apart into numerous "membrane vesicles".
Metaphase is the phase where all the genetic material is condensing into chromosomes.
Anaphase is the stage in which chromosomes are pulled by the spindle fibers to opposite poles of the cell.
In Telophase, the cell is nearly dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
Cytokinesis is the process which divides the cytoplasm of a parental cell into two daughter cells.
