A scientist has sequenced a gene from a multicellular eukaryotic organism. Brendan claims that by analyzing the gene sequence and applying
the genetic code, he can conclude the sequence of amino acids in the protein that forms after the gene is transcribed and translated
Which statement provides the strongest evidence against the validity of Brendan's claim?
A. Regulatory proteins may activate or deactivate a gene, often by very complex mechanisms.
B. During transcription, a strand of mRNA is synthesized from complementary base pairs, with the substitution of uracil (U) for thymine
(T)
C. During translation, anticodons on tRNA bind to codons on mRNA as part of the process that forms the polypeptide.
D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
Answer:
D. After a gene is transcribed, introns are removed from the pre-mRNA to form the mRNA that is translated.
Explanation:
According to this question, a gene was sequenced by scientists from an eukaryotic organism. Brendan claims he can conclude the resulting protein after the transcription and trans of the gene.
It is true that transcription and translation are the processes that a gene undergo in order to be expressed i.e. produce protein. However, a gene sequence contains both the coding and non-coding regions in it. The coding regions code for a protein and are called EXONS in the mRNA while the non-coding regions do not encode proteins and are called INTRONS in the mRNA.
These introns are removed from the mRNA molecule that results from the transcription of a gene. The mRNA undergoes a process called SPLICING, which removes the non-coding part of the mRNA (introns) and joins the coding parts (exons).
Hence, if this occurs, Brendan will not be able to accurately conclude the resulting protein from that gene sequence because a portion of that gene will still be removed during SPLICING of post-transcriptional processing.

Good luck on your assignment
______________________________
Rabbits can be best described as primary consumers. The correct option is b.
What are primary consumers?The 2nd trophic level is comprised of primary consumers. They are also known as herbivores. They just feed primary producers, including such plants or algae. A grasshopper, for example, is a primary consumer in the Everglades.
Primary consumers are rabbits because they are the first step up from autotrophs. Autotrophs, such as grass, are eaten by primary consumers such as rabbits.
The animals that eat the primary consumers are known as secondary consumers.
Herbivores are the primary consumers of plants. Primary consumers include caterpillars, insects, grasshoppers, termites, and hummingbirds, which only eat autotrophs (plants).
Rabbits are herbivores because they only eat plants - and herbivores are consumers because they eat plants to survive. Consumers include deer, grasshoppers, and rabbits.
Thus, the correct option is b.

Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”
Hypothesis: If the type of food available changes, then…
…because…
Answer: The independent variable of the lab is the type of food that is available to the birds. The food type changes in a given environment, then the amount of each type of bird beak will changes as birds with beaks more suited to the available food will consume more successfully over time.
Explanation:
With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.
What are different types of bird beaks?There are many types of beaks in birds, some of these can be:
Crushing beak.Curved beak.Piercing and tearing beak.Birds of prey.Stickybeak.With the changes in the available food, the frequency of the beak type will also change as birds with beaks better suited to the available food become more successful.

Read the passage from Darwin's journal. sorry its so long
The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.
What structural adaptation does the A. cristatus lizard have to help them climb rocks?
Awnsers:
A.strong claws
B.black color

Answer:
A) strong claws
Explanation:

Which is NOT a role played by a type of RNA in protein synthesis?
O mRNA transcribes the DNA template.
rRNA makes up ribosomes, which translate the genetic code into a protein.
O tRNA pairs RNA bases with amino acids.
O pRNA is the product of chemically linked amino acids.
Answer:
pRNA is the product of chemically linked amino acids.
Explanation:
All the other choices are exactly the roles of RNA in protein synthesis: mRNA "messenger" RNA transcribes the DNA and travels out of the nucleus; then rRNA "ribosomal" RNA in the ribosome helps assemble the protein using the mRNA; tRNA "transfer" RNA brings amino acids to the assembly line of ribosome and mRNA.
There is no pRNA that I know of, although there are many types of other RNAs like piRNAs (piwi RNAs!) or siRNAs.
When are two populations likely to have very similar allele frequencies?
A. If the selective pressures are different
B. If there is a high mutation rate
C. If there is a large amount of genetic drift
D. If there is a large amount of gene flow
Answer:
c). If there was a large amount of genetic drift.
If the price of gene drift is excessive enough, then two populations will have equivalent allele frequencies and consequently can be taken into consideration as a single powerful population.
What causes allele frequencies to live equally?Allele frequencies continue to be constant over the years due to the following: there is no considerable price of a brand new mutation. individuals with all genotypes are similarly able to mate and pass on their genes; that is, there's no choice against any precise genotype.
What are two impacts of allele frequencies of a population?The natural choice, genetic drift, and gene go with the flow are the mechanisms that purpose modifications in allele frequencies through the years. while one or greater of those forces are appearing in a populace, the populace violates the Hardy-Weinberg assumptions, and evolution occurs.

A bat wing, an alligator leg, and a human arm are homologous structures.
Which fact about those structures best supports one aspect of theory of evolution?
The fact that the bone structures are similar supports the concept that birds evolved from mammals.
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
The fact that the bone structures are completely different supports the concept that those organisms shared a common ancestor.
Answer:
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
Explanation:
The similarity of the wings of bats, legs of alligators, and arms of humans in structure is an indication that animals shared a common ancestor according to the evolution theory.
Homologous organs are organs found in different organisms that are similar in structure but different in functionality.
The fact that these organs are similar to each other in morphological structure points to the fact that they might have evolved from the same ancestor according to evolutionists.
The wings of bats, legs of alligators, and arms of humans are all based on the same pentadactyl (five-digit) structure. However, a bat uses its wing to fly, alligators use their legs to crawl, while humans use their arms for a variety of purposes.
The homologous organ is one of the pieces of evidence used to support the evolution theory.

How is glucose broken down in cellular respiration?
Answer: Glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria.
Explanation:
Glucose is broken down in cellular respiration into carbon dioxide and water.
What is cellular respiration?Cellular respiration is a series of metabolic processes that take place inside cells to transform biochemical energy from meals into a substance known as adenosine triphosphate (ATP).
A glucose molecule gradually decomposes into carbon dioxide and water during cellular respiration. In the process of transforming glucose, some ATP is directly created. But far more ATP is later created through a procedure known as oxidative phosphorylation.
Glycolysis is the process by which glucose is metabolized in the cytoplasm of the cell. The pyruvate molecules are delivered to the mitochondria in stage two.
Therefore, during cellular respiration, glucose is converted to carbon dioxide and water.
