Answer:

A codon is a triplet consisting of group of three bases found in mRNA sequence which eventually codes for amino acids and finally proteins.

Explanation:

A codon is a sequence of three nucleotides (bases) in a messenger RNA (mRNA) molecule that encodes for a specific amino acid or a stop signal during protein synthesis. Therefore, each codon is made up of three bases.

The sequence of bases in a codon determines the amino acid that will be added to the growing protein chain during translation.

For example, the codon AUG codes for the amino acid methionine, while the codon UGG codes for the amino acid tryptophan.

Codons are found in the coding sequence of an mRNA molecule, which is transcribed from the DNA template during gene expression.

The ribosome reads the mRNA codons during translation and matches each codon with a specific amino acid or a stop signal, thereby synthesizing a protein.

The genetic code, which maps each codon to a specific amino acid or a stop signal, is universal across all known organisms.

In Investigation B, Step 2 only a chemical change has occurred. Caramelization, which is a chemical change, takes place when the sugar solution is heated on a burner until the solution thickens and turns brown. All the other steps are physical changes.

Physical changes involve a change in the substance's shape or appearance but not its composition. In contrast, a chemical shift alters the nature of the matter and results in the formation of at least one new substance with novel features.

A non-enzymatic browning reaction is known as caramelization. The process results in the release of volatile molecules that give caramel its distinctive flavor. Both the breakdown of the sugar and the elimination of water (as steam) are components of the reaction. The type of sugar affects the caramelization reaction.

The size of the temporal foramen can provide some information about the size and strength of the temporalis muscle, which is responsible for closing the jaw during chewing. A larger temporal foramen would suggest a larger temporalis muscle and thus greater biting force.

The temporal foramen is a bony opening or aperture located on the side of the skull, just above the zygomatic arch (cheekbone). It is surrounded by several bones, including the temporal, zygomatic, and parietal bones.

In terms of diet, it is generally thought that species that consume tougher, more fibrous food items require stronger jaw muscles to generate the necessary force to chew and digest their food. Therefore, species with diets that consist of hard/tough items would likely have larger temporalis muscles and larger temporal foramina than species with softer diets.

However, this is a general trend and exceptions are possible, so it is important to consider other factors that may affect the size and strength of jaw muscles.

1. Fracture: Orbital floor of left eye. Sinus: Maxillary sinus.

2. Fracture affects eye movement by entrapment of inferior rectus muscle or nerve, limiting upward gaze and causing double vision.

1. Based on the provided information, it is likely that the patient has a fracture of the orbital floor, specifically the orbital floor of the left eye. The involvement of the left eye being fixed in downward gaze suggests a possible entrapment of the inferior rectus muscle or the inferior orbital nerve, which commonly occurs with orbital floor fractures. Additionally, the tenderness in the right cheek may indicate a possible blowout fracture, which involves the maxillary sinus.

2. The fracture of the orbital floor can affect the movement of the eye due to several reasons. Firstly, the entrapment of the inferior rectus muscle or the inferior orbital nerve can limit the normal upward movement of the affected eye, resulting in a fixed downward gaze as observed in the patient. This restriction can lead to double vision (also known as diplopia) when the eyes are not properly aligned.

The correct option is a. Divergent plate boundaries. Mountain ranges do not form at divergent plate boundaries. Instead, these boundaries are characterized by the creation of new oceanic crust through seafloor spreading, which causes the plates to move away from each other. Mountain ranges are formed at convergent plate boundaries, where two plates collide and the heavier plate subducts beneath the lighter plate, leading to volcanic activity and the formation of mountains. Transform plate boundaries are where two plates slide past each other, and they do not typically result in the formation of mountains. However, they can contribute to the formation and movement of existing mountain ranges by causing horizontal displacement along faults.

Two species of damselflies that are not sister species independently evolve a new mating behavior. This pattern is an example of convergent evolution, which is a(n) homoplasy. The correct option is C.

The pattern described, where two non-sister species independently evolve a new mating behavior, is an example of convergent evolution and homoplasy.

Convergent evolution occurs when unrelated species independently evolve similar traits or characteristics in response to similar selective pressures or ecological factors. In this case, the two species of damselflies, which are not closely related (not sister species), have independently evolved a new mating behavior. This suggests that they have responded to similar selective pressures or ecological conditions, leading to the convergence of this mating behavior.

Homoplasy refers to the independent evolution of similar traits or characteristics in different species, which is not inherited from a common ancestor. In this scenario, the new mating behavior evolved independently in each of the damselfly species, indicating homoplasy. It is not a synapomorphy because synapomorphies are shared derived traits inherited from a common ancestor.  The correct option is C.

The messenger RNA (mRNA) enters the free ribosome, and a polypeptide emerges.

The process of translation involves a large number of other molecules and macromolecules in addition to the mRNA template. Each component's composition may alter between species; for example, ribosomes may contain varying amounts of polypeptides and rRNAs depending on the organism. However, the overall designs and operations of the machinery responsible for protein synthesis in both bacterial and human cells are comparable. An mRNA template, ribosomes, tRNAs, and numerous enzyme components must all be present for translation to take place. Protein synthesis can be broken down into the same three processes as mRNA synthesis: initiation, elongation, and termination. Both prokaryotes and eukaryotes translate in a similar way. The process of translation in the prokaryote E. coli will be examined in this section, along with any distinctions between prokaryotic and eukaryotic translation.

The type of bond that dictates how the protein folds in the secondary structure of proteins is known as the hydrogen bond.

A hydrogen bond is a special type of intermolecular bond between a partially electronegative atom and a hydrogen atom attached to another electronegative atom. A hydrogen bond is a special type of dipole-dipole attraction that occurs between molecules that have a hydrogen atom bonded to nitrogen, fluorine, or oxygen. Hydrogen bonds are also responsible for the formation of the secondary structure of proteins.

These are composed of alpha helices and beta sheets. The protein chain is folded into a coil-like structure called an alpha helix in alpha helices. A beta sheet is a flat, sheet-like structure that folds in the shape of a zigzag and is made up of beta strands. In both cases, the hydrogen bonds between the protein chain's amino acid residues dictate the structure's overall shape.

Finally, hydrogen bonding is an important interaction in the tertiary structure of a protein. Hydrogen bonds between the R-groups of amino acids assist in the maintenance of the three-dimensional structure of a protein. These interactions are crucial in determining the protein's physical and chemical properties and can influence the protein's biological activity, folding, and stability.
