Which statement describes the blood type of a person with the alleles IAIB?
a. It is type AB because A and B exhibit incomplete dominance.
b. It is type AB because A and B are codominant.
c. It is type O because A and B are codominant.
d.It is type A because A and B exhibit incomplete dominance.
Answer: The correct answer is-
b. It is type AB because A and B are codominant.
In ABO blood typing, A and B are codominant alleles whereas allele O is recessive.
This means that an individual who inherits A and B alleles from his parents, would exhibit AB blood group.
This is because, being codominant, both A and B alleles will be expressed completely, resulting in AB blood group.
A person has always enjoyed eating tuna fish. Unfortunately, a recent study of the mercury content of canned tuna found that chunk white tuna contains 0.67 ppm hg. The u.S. Environmental protection agency recommends no more than 0.1 μg hg/kg body weight per day. If the person weighs 72 kg, how often may he/she eat a can containing 6 ounces (1 lb = 16 oz) of chunk white tuna so that he/she does not average more than 0.1 μg hg/kg body weight per day?
According to the Food and Drug Administration, five of the most generally consumed fish, which are low in mercury content are canned light tuna, shrimp, catfish, pollock, and salmon. However, another commonly consumed fish, that is, white tuna or albacore exhibits more mercury in comparison to the light canned tuna.
In the given case, mass of tuna is 6 oz = 6 × 28.3495 = 170.097 grams
Maximum mass of Hg permitted for 72 Kg body weight per day will be,
= 72 × 0.1 = 7.2 micrograms in a day
The concentration of white tuna in Hg = 0.67 ppm = 0.67 × 10^ (-6)
Mass of Hg = concentration × mass
= 0.67 × 10 ^ (-6) × 170.97
= 113.96 micrograms
Time between the consumption = 113.96 ÷ 7.2
= 16 days, that is, once in every 16 days.
Answer:
The answer is in 16 days.

4. plasma membrane
5. ribosome
6. cell wall
7. cell wall
In a bacterial cell, the flagella enable movement, pili aid in adhesion and genetic transfer, the nucleoid houses DNA, the plasma membrane regulates transport, ribosomes synthesize proteins, the cell wall provides structure, and the capsule enhances protection and virulence.
1. Flagella: Flagella are whip-like structures on the bacterial cell's surface responsible for locomotion. They rotate to propel the cell through its environment, allowing it to move towards favorable conditions or away from harmful ones.
2. Pilus: Pili (plural form: pilus) are hair-like appendages found on some bacterial cells. They serve multiple functions, including adherence to surfaces or other cells. Conjugation pili facilitate the transfer of genetic material between bacteria.
3. Nucleoid (DNA): The nucleoid is the region within the bacterial cell where the genetic material, a single circular DNA molecule, is located. Unlike eukaryotic cells, bacteria lack a membrane-bound nucleus.
4. Plasma Membrane: The plasma membrane is a semi-permeable barrier surrounding the cell, controlling the passage of molecules in and out. It plays a vital role in nutrient uptake and waste elimination.
5. Ribosome: Ribosomes are cellular structures responsible for protein synthesis. Bacterial ribosomes are smaller than those in eukaryotic cells and are crucial for the production of enzymes and other proteins.
6. Cell Wall: The cell wall provides structural support and shape to bacterial cells. It also helps protect the cell from osmotic pressure changes and is a target for antibiotics like penicillin.
7. Capsule: The capsule is a protective layer surrounding some bacterial cells. It helps evade the host immune system by preventing phagocytosis and enhances bacterial pathogenicity.

Propose a 5-year plan to phase out cement building blocks an replace them with more eco-friendly mycelium composites.
Answer:
Mycelium is the part of fungus consisting of a mass of branching thread like hyphae. It makes up the body of the fungus living on a particular substrate. Mycelium when dried can be a strong material which can be water, fire and mold resistant. Mycologist Philip Ross found out that dried mycelium can be grown and used for making building blocks. These mycelium bricks are organic and compostable. Their consistency is also stronger than concrete bricks. These mycelium bricks can be painted. These are bulletproof and can withstand extreme temperatures. When their use is over they can be composted therefore, biodegradable and does not harm nature in anyway. Hence, they are eco-friendly. Their durability and strong structural construct can be used for replacing them with other chemically synthesized building material. A five year plan with eco-friendly mycelium bricks can result when fungus mycelium bricks is considered only mandatory material for building construction purpose. Some durable and high tensile strength material if added in them can improve their quality provided that they are completely compostable.
Why do organisms have a common name and a scientific name?
The reason that organisms have common and scientific names is because there has to be a universal name for all organisms in theory.
Common names can be many different things, dependent on the area of the world you live in, Scientific Names are part of a series called binomial nomenclature which is a universal way to name all organisms. For example, a goose will be called anser anser across the world, then it changes some when you go into breeds, but for the most part, you can get by with that name.

Suppose the parents indicated in the interactive produced 192 peas. Determine the expected number of green and round offspring.
The number of the offspring produced in the dihybrid cross is 192.
In dihybrid cross, the ratio of the plants obtained in the F2 generation is 9: 3: 3: 1.
Thus, yellow round offspring is 9/16, green round offspring is 3/16, yellow wrinkled offspring is 3/16, and green wrinkled offspring is 1/16.
Thus, the number of green and round offspring produced can be calculated as:
Green round seed = 3/16
= 3/16 × 192
= 576/16
= 36
Thus, out of 192 peas, 36 will be green and round.
Suppose the parents indicated in the interactive produced 192 peas. Then the expected number of green and round offspring is thirty-six.
Further Explanation:
A recessive trait is defined as a trait that gets expressed by an individual when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as a recessive trait gets concealed by the presence of allele for the dominant trait.
The monohybrid cross is an experiment between the first generation organisms that differ in only one trait. The resultant ratio of the f-1 generation is 1:2:1. A Punnett square mainly used to predict the possible genetic outcomes of a monohybrid cross. Mainly the dihybrid cross occurs when there are two traits are present.
The total number of offspring produced in the dihybrid cross is 192. In the dihybrid cross, the ratio of the plants obtained in the F-2 generation is 9:3:3:1.
Now, yellow round offspring is 9/16
Green round offspring is 3/16
Yellow wrinkled offspring is 3/16
Green wrinkled offspring is 1/16.
Thus, the number of green and round offspring produced can be calculated as:
Green round seed = 3/16
= 3/16 × 192
=576/16
= 36
Thus, out of 192 peas, 36 will be green and round.

A facultative parasite refers to a species, which may resort to parasitic activity, but is not completely dependent on any host for finishing its life cycle. Therefore, the growth of Armillaria fungi inside a tree's roots, making the tree to rot, but will survive even if the tree dies, is an example of facultative parasitism.
An obligate parasite refers to a parasitic species, which cannot finish its life-cycle in the absence of a suitable host. Therefore, rickettsia bacteria's tendency to surviving only in a eukaryotic cell is an example of obligate parasitism.
A long-term symbiosis or biological association in which members of one species attain benefits while those of the other species is neither harmed nor are benefited is known as commensalism. Hence, a pseudoscorpion, a kind of arthropod hiding under the wings of beetle for protection and transportation, however, it does not affect the beetle is an example of commensalism.
Predation refers to a biological association, where one species, the predator, kills and consumes another species, known as prey. A freshwater amoeba feeds on bacteria in the water is an example of predator and prey.
Facultative parasitism, Armillaria fungi grow within a tree's roots, causing the tree to rot, but will survive if the tree dies.
Explanation:The above given fungi is an example of facultative parasitism because in facultative parasitism the organism lives in host and provide harm to it but it is not totally dependent on host. It can survive after the death of host.
Part 2.Obligate parasitism, Rickettsia bacteria can only survive in eukaryotic cells,
which are destroyed when the bacteria replicates .
Explanation:The rickettsia bacteria is best example of obligate parasitism because in this type of parasitism, an host is obligatory for the survival and reproduction of organism. They need the host and host cell for the completion of their life cycle.
Part 3.Commensalism, a pseudoscorpion, a type of arthropod, hides under a beetle's wings for protection and transportation, but does not affect the beetle.
Explanation:The commensalism is a type of symbiotic interaction between two organisms, in which one get benefited while other neither get benefit nor harm.
Hence in this example of pseudoscorpion, one organism a pseudoscorpion is getting protection from beetle while beetle is unaffected.
Part 4.Predator and prey, A freshwater amoeba feeds on bacteria in the water.
Explanation:Predator pray relationship between two organism, one is benefited while other get harm.
In above example, amoeba uses water bacteria for their food while these bacteria die due to amoeba. So this is obvious predator pray relation.

The name of a tripeptide depends on constituent amino acids, named from the N-terminal (start) to the C-terminal (end) using their three-letter abbreviations. For example, a tripeptide composed of Valine, Leucine, and Serine will be named 'Val-Leu-Ser'.
Explanation:The question didn't provide a specific tripeptide to name, but based on the information given, here's how you would approach this. Amino acids in a peptide are named from the N-terminal (start of the peptide, free amino group) to the C-terminal (end of the peptide, free carboxyl group). Each amino acid is known by its three-letter abbreviation, for example, 'gly' for glycine, 'ala' for alanine, and 'phe' for phenylalanine.
Therefore, if you had a tripeptide made up of, for instance, valine (Val), leucine (Leu), and serine (Ser), you would name it 'Val-Leu-Ser'. This essentially involves naming each amino acid in the order they appear in the tripeptide chain.
It's also important to remember that when naming a peptide, the N-terminal amino acid comes first. So in our example, Valine is the N-terminal amino acid, and serine is the C-terminal amino acid.
