which structure is highlighted? multiple choice auditory ossicles auricle tympanic membrane vestibule semicircular ducts
Semicircular ducts or Semicircular Canals are highlighted.
What are Semicircular Canals?
The semicircular canals are three small fluid-filled tubes in the inner ear that help you balance. Movement of the head causes fluid to splash within the semicircular canals, moving the tiny hairs that line each canal. These hairs translate fluid movement into neural messages sent to the brain. Your brain can tell your body how to maintain balance. When you twist and then stop, the fluid in the semi-circular channel travels a little longer, and the hair continues to send the message that it's spinning even though it's not. That's why you feel dizzy after carnivals and amusement park rides.
Therefore, Semicircular ducts or Semicircular Canals are highlighted.

how long can uncooked thawed lobster stay in fridge?
If you have thawed uncooked lobster in the fridge, it should be cooked and eaten within 1-2 days for the best quality and safety. After that time, the lobster may start to spoil and develop off flavors and odors.
It's important to keep the lobster refrigerated at a temperature of 40°F (4°C) or below during this time, to prevent the growth of harmful bacteria that can cause foodborne illness.
If you don't plan to cook the lobster within 1-2 days, you can also freeze it for later use. To freeze uncooked lobster, wrap it tightly in plastic wrap or aluminum foil, and then place it in an airtight container or freezer bag. It can be stored in the freezer for up to 6 months. When you're ready to cook the lobster, thaw it in the refrigerator overnight before cooking.

The life cycle of the sheep liver fluke, a trematode with the scientific name Fasciola hepatica, is digenetic--it spends part of its life in a sheep's liver, and another part of it in an aquatic snail.
The adult fluke will shed its eggs in the sheep feces where the eggs will divide to form the miracidium. This larva will then penetrate a snail where it will form a sporocyst that becomes a redia which will divide to form daughters. These escape into water where they will encyst on grass that is eaten by a sheep that perpetuates the life cycle.
The life cycle of Fasciola hepatica begins when the adult fluke sheds its eggs in sheep feces. These eggs develop into miracidia, the first larval stage. The miracidia penetrate the aquatic snail and transform into sporocysts, which in turn develop into rediae.
The rediae divide to produce daughter rediae, which then develop into cercariae. These cercariae escape from the snail and encyst on grass as metacercariae. When a sheep consumes the grass, it ingests the metacercariae, which then migrate to the liver, completing the life cycle.

Explanation:
The genomic DNA of an organism has a base composition of 20% C–G base pairs and 80% A–T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
The expected frequency of the Tsp E1 restriction enzymes sites 5'-CCGG-3' is 0.16.
Restriction enzymes identify and cut DNA strands at specific base sequence motifs called recognition sequences or restriction sites. This motif is usually 4 to 8 base pairs long, and it can be palindromic or asymmetric.
TspEI has a 4-base pair motif of CCGG. So the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' is 0.16.
As mentioned above, the Tsp E1 restriction sites contain a 4-base pair motif of CCGG. Since the genomic DNA of the organism contains 20% C–G base pairs and 80% A–T base pairs, there are four possible nucleotides that can be present in the recognition sequence: cytosine (C), guanine (G), adenine (A), and thymine (T).
The frequency of C and G bases is 20/2 = 10%. The frequency of A and T bases is 80/2 = 40%.
To calculate the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3', we need to know the frequency of each individual nucleotide at the 4 positions of the recognition sequence. Since the bases are assumed to be randomly distributed, we can use the multiplication rule to find the probability of each possibility.
P(5'-C1-3') = P(C)
= 0.1P(5'-C2-3')
= P(C)
= 0.1P(5'-G3-3')
= P(G) = 0.1P(5'-G4-3')
= P(G)
= 0.1
Multiplying all probabilities together: P(5'-CCGG-3') = P(C) x P(C) x P(G) x P(G)
= 0.1 x 0.1 x 0.1 x 0.1
= 0.001
Thus, the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' is 0.001 or 0.1%. This means that out of every 1000 base pairs in the genomic DNA, we can expect to find the Tsp E1 restriction sites approximately 1 time. In conclusion, the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' is 0.16.

The major difference between codominance and incomplete dominance is that in codominance ...
both alleles are expressed in the heterozygote
the dominant allele determines the phenotype of the heterozygote
there is a blending of alleles in the heterozygote
Answer:
The major difference between codominance and incomplete dominance is that in codominance, both alleles are expressed in the heterozygote. In incomplete dominance, one allele is expressed more strongly than the other, but both alleles are still present.
In codominance, the phenotype of the heterozygote is a combination of the phenotypes of the homozygotes. For example, a person with blood type AB has both the A and B antigens on their red blood cells.
In incomplete dominance, the phenotype of the heterozygote is somewhere in between the phenotypes of the homozygotes. For example, a person with blood type AB has a darker skin color than a person with blood type A, but not as dark as a person with blood type B.

9. Summarize how transcription makes mRNA. A complete answer will include: gene, mRNA, sequence, nucleotides, complementary, RNA polymerase, base-pairing rules.
Answer:
Explanation:
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteinsThe main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.
Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.Elongation. One strand of DNA, the template strand, acts as a template for RNA polymerase. As it "reads" this template one base at a time, the polymerase builds an RNA molecule out of complementary nucleotides, making a chain that grows from 5' to 3'. The RNA transcript carries the same information as the non-template (coding) strand of DNA, but it contains the base uracil (U) instead of thymine (T). [What do 5' and 3' mean?]Termination. Sequences called terminators signal that the RNA transcript is complete. Once they are transcribed, they cause the transcript to be released from the RNA polymerase. An example of a termination mechanism involving formation of a hairpin in the RNA is shown belowIn bacteria, RNA transcripts can act as messenger RNAs (mRNAs) right away. In eukaryotes, the transcript of a protein-coding gene is called a pre-mRNA and must go through extra processing before it can direct translation.
Eukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end).
Many eukaryotic pre-mRNAs undergo splicing. In this process, parts of the pre-mRNA (called introns) are chopped out, and the remaining pieces (called exons) are stuck back together.
End modifications increase the stability of the mRNA, while splicing gives the mRNA its correct sequence. (If the introns are not removed, they'll be translated along with the exons, producing a "gibberish" polypeptide.)
To learn more about pre-mRNA modifications in eukaryotes, check out the article on pre-mRNA processing. op this helps !
Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.
Transcription occurs in three steps—initiation, elongation, and termination.
What are the three roles of RNA polymerase in transcription?
Eukaryotic cells contain three distinct nuclear RNA polymerases that transcribe distinct classes of genes.
Protein-coding genes are transcribed by RNA polymerase II to yield mRNAs, ribosomal RNAs (rRNAs) and transfer RNAs (tRNAs) are transcribed by RNA polymerases I and III.
Thus, this is the summary of the transcription.

in which type of ecosystem does phosphorous have the slowest turn-over rate? group of answer choices boreal forest temperate coniferous forest temperate deciduous forest chaparral tropical rainforest
Phosphorus has the slowest turnover rate in Tropical rainforests.
The phosphorus cycle is important to understand when learning about nutrient cycles in an ecosystem. Keep on reading to understand better about it.
The phosphorus cycle is a biogeochemical cycle, which describes the transformation of phosphorus through different forms in ecosystems. In this cycle, phosphorus is transferred from the atmosphere to the lithosphere, biosphere, and hydrosphere, and then back again to the lithosphere over a long geological timescale. The cycle is often slow because of the gradual weathering and erosion of rocks, which release phosphorus into the soil.
The phosphorus cycle is crucial for the survival of all living organisms because phosphorus is an essential nutrient required for the growth of plants and animals. However, it is often the limiting nutrient in aquatic ecosystems because of its slow turnover rate. That's why phosphorus is usually in low concentrations in the ecosystem. Phosphorus has the slowest turnover rate in the tropical rainforest ecosystem.
This is because the warm and humid climate of tropical rainforests favors the rapid weathering of rock, which leads to the release of phosphorus into the soil. Therefore, phosphorus is more available for plants to absorb, which leads to a higher rate of growth and decomposition of plant matter. Additionally, the dense forest canopy in tropical rainforests limits the amount of sunlight that reaches the ground, which slows down the rate of photosynthesis and the growth of plants.
