Answer: Identify the promoter and the stop signal (terminator).
Explanation:
DNA is a molecule that contains the genetic information in all living things. This information is used for the synthesis of proteins that make up the body and carry out vital functions of the organism.
The DNA molecule consists of two strands that wind around each other to form a double helix structure, where each strand has a central part formed by sugars (deoxyribose in the case of DNA) and phosphate groups. The four basic components of DNA are nucleotides: adenine (A), thymine (T), guanine (G) and cytosine (C). The nucleotides are joined together (A to T and G to C) by chemical bonds and form base pairs that connect the two strands of DNA. Depending on the sequence of nucleotides (which have different bases), different proteins are synthesized.
DNA replication consists of synthesizing another identical DNA molecule, using enzymes called polymerases, which are molecules specifically dedicated only to copy DNA. Transcription, on the other hand, is the process by which a copy of messenger RNA (mRNA) is generated from the sequence of a gene in the DNA. This RNA molecule leaves the cell nucleus and enters the cytoplasm, where it directs protein synthesis (a polymer made up of many amino acids).
Protein synthesis, or translation, involves translating the sequence of an mRNA molecule into an amino acid sequence during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding sequence of amino acids it encodes. To begin translation, a start codon (set of 3 bases) must first be identified, which is usually AUG that also codes for the amino acid methionine. Then, the codons that follow are read and the corresponding amino acids are added according to the genetic code. The transfer RNA (tRNA) is complementary to the anticodon at specific codons in the messenger RNA and carries the amino acid coding for the codon. In addition, ribosomal RNA (rRNA) is an RNA that is part of ribosomes and is essential for protein synthesis in all living things. rRNAs form the framework of ribosomes and associate with specific proteins to form ribosomal pre-subunits. To finish the translation, a termination codon has to be read, which can be UGA, UAG or UAA.
To revise the model to show transcription to form mRNA, the research should identify the promoter and the stop signal. The promoter is a DNA sequence required to turn a gene on or off. The transcription process starts at the promoter which is usually located near the beginning of a gene and has a binding site for the enzyme that is used to make a messenger RNA (mRNA) molecule. The enzyme RNA polymerase will keep doing the transcription until it reaches a sequence of DNA that is signal which indicates it should stop. This process is called termination, and it happens once the enzyme reaches this sequence, called terminator.

Which organisms are secondary consumers in this food web? Select all that apply
Rockskipper, Pufferfish and Peacock Flounder are secondary consumers in this food web. So, the correct options are A, B and C.
What is Food web?A food web is a diagram that shows what is eaten with what in an ecological context and how food chains naturally connect to one another. Consumer-resource system is another term for the food web.
A food web is a comprehensive account of the species that make up an ecosystem and their interactions with one another. It demonstrates how energy is moved along food chains that are connected to other food chains.
After primary consumers, who are primarily herbivores, are omnivores, carnivores, and secondary and tertiary consumers. The apex predators are those animals that have no other predators save humans. They are at the highest point in the food chain.
Therefore, the correct options are A, B and C.

Which statement best describes the movement of ocean waves? Water moves across the ocean's surface water remains in the same place as wave (energy) travels through it water moves because there is a difference in density of the water creating a wave none of these
Answer:
water remains in the same place as wave (energy) travels through it
Explanation:
Winds influence the ocean and its movements. Air current running on the ocean surface transfers energy to water. A wave is nothing else than energy. When the winds provide energy to the water surface and produce waves, it occurs a particular water molecules´ motion. They move in circles from up to down, up to a certain depth, and go back to the surface. And they do so while energy from the wave is passing through. Waves are the ones that move through the ocean until they reach the shore, where the energy is transferred to land. Water molecules remain in the same general area, while energy travels from molecule to molecule as a wave.

what was explained by darwins theory of biological evolution
Answer:
When Organism A has a trait that negatively impacts it, or lacks a trait which would positively impact it, then said organism perishes, and its genes are not passed onto the next generation. On the flip side, when Organism B has a trait that positively impacts it, or lacks a trait that would negatively impact it, then the organism thrives, and its genes are passed onto the next generation.
Therefore, the next generation receives genes from Organism B and does not receive genes from Organism A. So, the next generation has traits that positively impact it and lacks traits that would negatively impact it, thus evolving according to Darwin.

What was explained by it? Evolution. But how did it explain evolution? That is in the answer.

In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to produce a heterozygous F1 generation. Two F1 individuals are mated, and you do not see a 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio of offspring, but instead see that almost all offspring are a non-recombinant phenotype. This tells you that
Answer:
Epistasis effect result into these offspring
Explanation:
Given
spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b)
Genotype of true-breeding black spotted rabbit BBSS
Genotype of true-breeding brown solid rabbit bbss
Genotype of offspring BbSs
In normal crossing between BbSs and BbSs offspring of F1, should produce offspring in the ratio 9:3:3:1
But it does not happens in this case the simple reason could be presence of Epistasis in which the alleles assort independently but do not express themselves because of the following reasons -
a) Interaction between two or more loci thereby resulting into new phenotypes
b) An allele at one locus masks effects of other allele at one or more loci
c) Allele at one locus modifies the effects of alleles at one or more other loci
