Answer:

All viruses depend on cells for reproduction and metabolic processes. By themselves, viruses do not encode for all of the enzymes necessary for viral replication. But within a host cell, a virus can commandeer cellular machinery to produce more viral particles. Bacteriophages replicate only in the cytoplasm, since prokaryotic cells do not have a nucleus or organelles. In eukaryotic cells, most DNA viruses can replicate inside the nucleus, with an exception observed in the large DNA viruses, such as the poxviruses, that can replicate in the cytoplasm. RNA viruses that infect animal cells often replicate in the cytoplasm.

The Life Cycle of Viruses with Prokaryote Hosts

The life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis. Temperate phages, on the other hand, can become part of a host chromosome and are replicated with the cell genome until such time as they are induced to make newly assembled viruses, or progeny viruses.

The Lytic Cycle

During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages. There are five stages in the bacteriophage lytic cycle (see Figure 1). Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces). Most phages have a narrow host range and may infect one species of bacteria or one strain within a species. This unique recognition can be exploited for targeted treatment of bacterial infection by phage therapy or for phage typing to identify unique bacterial subspecies or strains. The second stage of infection is entry or penetration. This occurs through contraction of the tail sheath, which acts like a hypodermic needle to inject the viral genome through the cell wall and membrane. The phage head and remaining components remain outside the bacteria.

This figure outlines the stages of the lytic cycle. Step 1 is attachment when the phage attaches to the surface of the host. The bacteriophage is shown sitting on the surface of the bacterial host cell. Step 2 is penetration when the viral DNA enters the host cell. The image shows DNA from within the virus being injected into the host DNA. Step 3 is biosynthesis when the phage DNA replicates and the phage proteins are made. The image shows various pieces of virus being built within the cell. Step 4 is maturation when the new phage particles are assembled. This shows the viral components being put together in the cell. The fifth step is lysis when the cell lyses and the newly made phages are released. This shows the cell bursting and built viruses being released.

Figure 1. A virulent phage shows only the lytic cycle pictured here. In the lytic cycle, the phage replicates and lyses the host cell.

The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome. It then hijacks the host cell to replicate, transcribe, and translate the necessary viral components (capsomeres, sheath, base plates, tail fibers, and viral enzymes) for the assembly of new viruses. Polymerase genes are usually expressed early in the cycle, while capsid and tail proteins are expressed later. During the maturation phase, new virions are created. To liberate free phages, the bacterial cell wall is disrupted by phage proteins such as holin or lysozyme. The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.

Ferredoxin transfer an electron to nadp. Through Fe-S clusters whose iron cations swing between +2 (ferrous) oxidation states and +3, the iron-sulfur protein ferredoxin facilitates electron transport in a vast variety of redox processes in cellular metabolism (ferric).

From the anaerobic bacterium Clostridium pasteurianum, the first protein of this kind was identified in 1962. The cyclic and noncyclic photophosphorylation processes of photosynthesis are mediated by a ferredoxin peculiar to chloroplasts. Ferredoxin-NADP + reductase (EC 1.18.1.2) lowers NADP + with FAD and a flavin group as cofactors, and ferredoxin serves as the final electron acceptor in non-cyclic photophosphorylation:

\([Fe(2+)Fe(3+)S_{2} (-2)] + NADP(+) + H^{+} ==== > 2 ferredoxin [Fe_{3} (+2)S_{2}(-2)] + NADPH\)

The laws of thermodynamics govern the behavior of energy, and there are four of them.

All these laws are used to describe the energy and its properties. However, in this particular question, the first and second laws of thermodynamics are of relevance. Hence, here are the appropriate laws for the given events:1ST LAW OF THERMODYNAMICS: The first law of thermodynamics is the law of energy conservation. It states that energy can neither be created nor destroyed; rather, it can only be converted from one form to another. Hence, the event that falls under the first law of thermodynamics is the following: Your meals arrive, and your food is served.2ND LAW OF THERMODYNAMICS: The second law of thermodynamics concerns the natural flow of energy. It is the law of entropy, which states that energy is always flowing from areas of high concentration to areas of low concentration. Hence, the events that fall under the second law of thermodynamics are the following: Your and your friend are really hungry, and your stomachs growl. Your food is being cooked in the kitchen. A few hours after the meal, you start to feel hungry again. Your glass of water falls off the table and spills everywhere. These are the appropriate laws for the given events.

The upper and lower tidal zones in which the barnacles Balanus and Chthalamus thrive when both species are present illustrate the principle of Competitive Exclusion.

Competitive Exclusion Principle is the idea that two species that share the same ecological niche cannot coexist indefinitely. One will ultimately outcompete and displace the other.The two barnacle species, Balanus and Chthalamus, share the same ecological niche and so are forced to compete for space and resources. They have a strong competitive relationship in which they try to gain an advantage over one another.

Balanus is usually the dominant species in the upper tidal zone, where it can tolerate the higher levels of exposure to air and sunlight. While Chthalamus is generally the dominant species in the lower tidal zone, where the water is usually colder and more turbulent, which is more favorable to its growth and survival.

Both species are well adapted to their respective tidal zones, but they have slightly different requirements, so they don't compete too intensely for resources. In this way, they are able to coexist without completely excluding each other from the ecosystem. Therefore, they demonstrate the principle of Competitive Exclusion in the upper and lower tidal zones in which they thrive.

The correct answer is : proton and electron (opposite charges).

Explanation:

Water is a polar molecule as it has equal number of electron and proton. Electron and protons are present on different end of water molecule, negative charge due to electrons at end of oxygen, while positive charge at end of hydrogen due to protons.

Equal number of electron and proton make it neutral or no net charge molecule however having opposite charge on its end makes is polar.

Thus, the correct answer is: proton and electron.

The gametophyte is one of the two alternative multicellular phases in the life cycles of plants and algae.

While gametophytes exhibit a haploid, gamete-forming stage of the plant's life cycle, sporrophytes exhibit a diploid, spore-forming stage. Green algae have isomorphic gametophytes and sporophytes (indistinguishable). Given that it is the most obvious stage in their life cycle, the gametophyte stage is common among bryophytes like mosses. Ferns and seed plants are examples of sporophytes, the earliest stage of vascular plants. As a result, mosses have the longest gametophyte stage and seed plants have the shortest. Bryophytes are more likely to be at the gametophyte stage than the sporophyte stage as compared to higher (i.e., vascular) plants. Despite the fact that certain types of algae have preset life cycles, environmental conditions frequently have an influence on the dominant phase in the majority of algae.

The concept of homologous structures is an important aspect of evolutionary biology. Homologous structures are those that have a common origin but may have different functions.

The common limb structure found in vertebrates is a prime example of a homologous structure that provides evidence for evolution. This structure is present in different animals such as birds, reptiles, and mammals, indicating a common ancestry between these organisms.

The embryonic origin of the limb structure is also important evidence for evolution. During development, the limb structure begins to form in the embryo and follows a similar pattern across different species. This suggests that the development of the limb structure has been conserved over time and that it has been inherited from a common ancestor.
