The correct order of the final three stages in the lytic cycle is Assembly > Transduction > Release
What is a Lytic cycle ?One of the two viral reproduction cycles, the other being the lysogenic cycle, is the lytic cycle. The infected cell and its membrane are destroyed as a result of the lytic cycle. Virulent phages are bacteriophages that only utilise the lytic cycle.
Although the lytic cycle's final result is the generation of new phage offspring and the death of the host bacterial cell, this is a multistep process that requires careful synchronisation of physical processes and gene transcription.The primary distinction between the lytic and lysogenic cycles is that the lytic cycle kills the host cell, but the lysogenic cycle does not. The host cell's DNA is destroyed by viral DNA, which also halts the cell's lytic cycle.Learn more about Lytic cycle here:

Photosynthesis and cellularrespiration
Answers
Answer:
Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? explain your answer by describing the structure of each macromolecule.
Answers
Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.
As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.
1. Protein structure
Amino acid polymers form proteins. There are four different types of proteins, based on structure.The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.
3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

Cellular respiration is a series of metabolic reactions in which the energy from organic molecules, such as glucose, is released and used to synthesize.
Answers
Cellular respiration is a series of metabolic reactions in which the energy from organic molecules, such as glucose, is released and used to synthesize energy in the form of ATP.
The chemical reaction that converts glucose and oxygen into water, carbon dioxide, and ATP energy is known as cellular respiration. Oxygen and glucose are the reactants in the process, and the products are water, carbon dioxide, and energy (ATP). Therefore, we can say that cellular respiration is a series of metabolic reactions that is used to synthesize ATP.
The controlled release of energy from organic substances during cell respiration results in the production of ATP. ATP, adenosine triphosphate, is required in every kind of bodily reactions and to conduct various body functions. Mitochondria is the primary site of ATP synthesis in a cell. These organelles consume glucose to convert it into energy molecules and other by-products.

Answers
Some microbiologists prefer to open and close quickly the culture tube instead of flaming its mouth prior and after transferring bacteria to or from it because it prevents spills more effectively because it eliminates the necessity of an open flame
What are the risks associated with utilising direct burning to control bacteria?Contamination danger is increased. Not all contagious components will be promptly deactivated and destroyed when an item is exposed to open flames.
Flaming the Test Tube's Mouth: A convection current is produced when the mouth of a tube is passed past the flame of a Bunsen burner, forcing air out of the tube. By doing this, pollutants from the air are kept out of the tube.
Flaming is used to warm the bottle's opening and produce air convection currents that move away from the opening rather than sterilising it (i.e., updraft). The heated, rising air helps keep contaminants and other impurities out of the bottle.

The ara operon is an inducible operon that controls the production of the sugar arabinose. When arabinose is present in a bacterium it binds to the protein AraC, and the complex binds to the initiator site to promote transcription. In this scenario, AraC is a(n) activator.
The process of transcription uses the DNA found in the nuceloids of bacteria cells to create messenger RNA. However, the generation of these mRNA is dependent on the intracellular state of the bacterium, such as whether or not the protein encoded by the segment is required.
Only when there is no arabinose sugar present in the cell can AraC function as a repressor in this particular bacteria. AraC will function as an activator in the aforementioned context since sugar arabinose is present.

Answers
Consider a mutation that causes a decreased activity in a particular protein. A second mutation alters the function of another protein that participates in the same cellular pathway, thereby overcoming the defect in the first protein. This is an example of a(n) (C) intergenic suppressor.
In a procedure known as synthetic rescue, a suppressor mutation is a second mutation that lessens or reverses the phenotypic consequences of an already existing mutant. Therefore, genetic suppression brings back the phenotype that existed before the initial background mutation.
By causing a mutation elsewhere in the genome, intergenic suppression mitigates the impact of a mutation in one gene. The second mutation does not occur on the identical gene as the first one. For finding and researching interactions between molecules, such as proteins, intergenic suppression is helpful.
For instance, a second mutation elsewhere in the genome that restores or creates a suitable alternative connection between those molecules can make up for a mutation that breaks the complimentary interaction between protein molecules.
