In prokaryotes, what type of RNA can and cannot be be used ? How about for Eukaryotes?
Thanks!
In prokaryotes, the type of RNA that can and cannot be used are dependent on the function it serves.In prokaryotes, three types of RNA can be used whereas RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes.
Prokaryotes are unicellular organisms that do not have a nucleus or membrane-bound organelles. The genetic material is present in the cytoplasm and is arranged in a single, circular DNA molecule. As a result, the RNA transcription and translation occurs in the same location. As a result, there is no alternative splicing or post-transcriptional modification.
Hence, all RNAs are synthesized from a single, uninterrupted gene.In prokaryotes, three types of RNA can be used: Messenger RNA (mRNA) transcribes the genetic information from DNA, which is then translated into a protein. Ribosomal RNA (rRNA) is a major component of ribosomes and is essential for protein synthesis. Transfer RNA (tRNA) is a specialized RNA molecule that carries amino acids to the ribosome during translation. In prokaryotes, RNA that undergoes splicing, such as hnRNA or pre-mRNA, is not used.Eukaryotes are multicellular organisms that have a nucleus and membrane-bound organelles.
Eukaryotic cells have linear DNA arranged into chromosomes and are located in the nucleus. RNA transcription occurs in the nucleus, while translation occurs in the cytoplasm. Eukaryotes also have alternative splicing and post-transcriptional modification. So,RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes. Eukaryotes have five types of RNA that can be used: Messenger RNA (mRNA), Ribosomal RNA (rRNA), Transfer RNA (tRNA), Small nuclear RNA (snRNA), and Small nucleolar RNA (snoRNA). RNA that doesn't undergo alternative splicing, such as rRNA, snRNA, and snoRNA, is not used in eukaryotes.

Why do mutations code proteins?
Answer:
A nonsense mutation is a genetic mutation in a DNA sequence that results in a shorter, unfinished protein product. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop signal (stop codon).

LL LL
ULI
What is the phenotype ratio for this cross?
O A. One long, three short
B. Four long, zero short
O C. Two long, two short
O D. Three long, one short
PREVIOUS
Answer:
The punnet square in this question is unclear. The punnet square has been attached as an image.
Based on the punnet square, the answer is C. Two long, two short
Explanation:
This question involves a single gene coding for needle length in cactus plant. The allele for long needle (L) is dominant over the allele for short needle (l).
According to the question, two cacti were crossed with genotypes Ll and ll respectively. The following allelic combinations of gametes will be produced by each parent
Ll- L and l
ll- l and l
Using these gametes in a punnet square (as seen in the image below), four possible offsprings with genotypes: Ll and ll will be produced in a 1:1 proportion.
Ll offsprings will be phenotypically long-needled while ll offsprings will be phenotypically short-needled. Hence, two long needle offsprings and two short needle offsprings will be produced in this cross.

1. _____ is when one species splits into two species or when one species transforms into another over time.
- Reproductive isolation
-Convergent evolution
-The founder effect
-Speciation
-Both reproductive isolation and speciation are correct.
Both reproductive isolation and speciation are when one species splits into two species or when one species transforms into another over time.
Speciation is the process by which populations transform into various species. Cladogenesis, the separation of lineages, was first described by the scientist Orator F. Cook in 1906. Cladogenesis is in contrast to anagenesis, which relates to phyletic evolution within lineages. Charles Darwin was the first to explore how natural selection contributes to speciation in his 1859 book On the Origin of Species. He found it troublesome, but he acknowledged the possibility. There are four geographic modalities of speciation in nature, depending on how far apart the populations that are speciating from one another are from one another: sympatric, parapatric, peripatric, and allopatric. Additionally, farming, scientific experimentation, and animal care can all be used to induce artificial speciation. The relative importance of genetic drift to speciation is a topic of intense discussion. Rapid sympatric speciation can take place through polyploidy, such as when the number of chromosomes is doubled, leading to children that are instantly reproductively isolated from the parent population. Through hybridization and reproductive isolation, new species may be created if natural selection favors the hybrid.

If the government sets a price ceiling on dog food that is below the equilibrium price, _______. A. a surplus of dog food occurs B. new firms enter the industry to meet the increase in demand that results from the decrease in price C. a shortage of dog food occurs D. existing firms in the dog food industry expand production to meet the increase in the quantity demanded
If the government sets a price ceiling on dog food that is below the equilibrium price a shortage of dog food occurs. The correct answer is C.
When the government sets a price ceiling on dog food that is below the equilibrium price, it creates a situation where the maximum price that can be charged for dog food is lower than what would naturally occur in the market. This price ceiling prevents the market from reaching equilibrium, leading to a shortage of dog food.
Due to the lower price ceiling, suppliers are unable to charge the market price that would allow them to cover their costs and make a profit. As a result, some suppliers may choose to reduce their production or exit the industry altogether. This decrease in the quantity supplied leads to a shortage of dog food, as the quantity demanded at the lower price exceeds the quantity supplied.
Consumers, on the other hand, are incentivized by the lower price to demand more dog food. This increased demand exacerbates the shortage, as the quantity demanded exceeds the quantity supplied at the price ceiling. As a result, consumers may face difficulties in finding and purchasing dog food, leading to a shortage in the market. Therefore, the correct answer is C.

Barnacles create home sites by attaching themselves to whales.
This neither harms nor benefits the whales. but i need to explain my answer.
The relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.
Barnacles are a type of sessile organism, which means they are unable to move freely from one location to another. In order to survive, they need to attach themselves to a solid surface, such as a rock or the skin of a whale. When barnacles attach themselves to the skin of a whale, they create a home site where they can filter-feed and reproduce.
While the barnacles benefit from this relationship by gaining a home site, there is no evidence to suggest that the whales benefit or are harmed by having barnacles attached to their skin. Barnacles do not consume or harm the whale's skin or tissues, and there is no evidence to suggest that the presence of barnacles has any impact on the whale's health or behavior.
Therefore, the relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.
