The deep sea primary producers obtain carbon dioxide for fixation through a series of chemical reactions to produce organic compounds. They cannot use sunlight energy to perform the photosynthesis.
Producers are the organisms that make their own food. The example of such organisms are plants, some bacteria, and fungi. The plants perform photosynthesis for synthesizing food. They obtain the primary position in any food chain or pyramid.
Photosynthesis is the process by which plants synthesize food using inorganic raw materials such as solar energy, water, and carbon dioxide, producing sugars and the byproduct oxygen. It occurs in two phases: light-dependent reactions and light-independent reactions.

cawhich one of these is a polymer of glucose that we (animals) can convert back into glucose monomers if needed?
When necessary, animals like us may break down the glucose polymer known as glycogen back into its monomer form.
Both fungi and animals use the glucose polymer known as glycogen to store energy. The primary glucose storage type in the body is shown by the polysaccharide structure of glucose. The cells of the liver and muscles create and store glycogen while being hydrated with the four parts of water. It functions as a long-term energy storage reserve. Glycogen in muscles is quickly transformed into glucose by muscle cells, whereas liver glycogen does the same for the entire body, including the central nervous system.
Glycogen is a long polymer chain of glucose molecules joined by an alpha-acetal bond.
This acetal bond is created when the alcoholic and carbonyl groups combine. If the carbonyl group is an aldehyde group i.e(-CHO) and also termed as hemiacetal if there is a ketonic group. The acetal group is what results from the bonding of two alkoxy groups to the same carbon atom.

Which one of these is a polymer of glucose that we (animals) can convert back into glucose monomers if needed?

An analogy is a similarity due to convergent evolution, resulting in similar adaptations.
a. True
b. False
The statement that An analogy is a similarity due to convergent evolution, resulting in similar adaptations is true.
Analogy is similarity due to convergent evolution. Convergent evolution occurs when certain environmental pressures and natural selection produce similar adaptations in organisms from different evolutionary lineages. All organisms have derived their traits from the ancestors. They can either be homologous or analogous. Homologous structures have a similar embryonic origin but on the other hand analogous organs have a similar function. Convergent evolution simply signifies the fact that organisms with different ancestral origin, over a period of time adapt to perform certain similar functions. For example, the wings of birds and butterflies are adapted to perform the function of flight, flippers of Penguins and Dolphins to swim etc.

Hybrid speciation occurs when two existing species hybridize and a new species forms through the accidental alterations that can occur during cell division. Hybrid Speciation: The Evolution of a New Species Through Accidental Alterations in Cell DivisionHybrid speciation is a process of natural evolution which occurs when two existing species hybridize and a new species forms through the accidental alterations that can occur during cell division. These alterations can lead to new characteristics and traits that may give the new species an advantage over existing species in the same environment.
This process is often driven by a variety of factors, such as changes in the environment, competition for resources, and even the presence of different predators. Hybridization between two species is an unpredictable event, and the new species created may be better adapted for survival. Over time, this new species may become distinct enough to be considered a separate species from its parent species, allowing it to thrive and reproduce in its own environment.

A medication is a drug that is used to identify, treat, or prevent disease. It is also referred to as a medicament, medicine, pharmaceutical drug, or simply a drug. A significant area of medicine is drug therapy, or pharmacotherapy, which depends on the science of pharmacology for ongoing development and on pharmacy for effective management. There are many different categories for drugs. One of the important divides is by level of control, which separates prescription pharmaceuticals from over-the-counter medicines (prescription drugs are those that a pharmacist can only give on the advice of a doctor, physician assistant, or licensed nurse) (those that consumers can order for themselves). Traditional small molecule drugs, which are typically made through chemical synthesis, and biopharmaceuticals, which include recombinant proteins, vaccines, blood products used for therapeutic purposes (like IVIG), gene therapy, monoclonal antibodies, and cell therapy, are another important distinction (for instance, stem cell therapies). Biological systems impacted, delivery method, mode of action, and therapeutic outcomes are further classification categories for medications.

unlike bacterial infections, populations of pathogenic viruses do not evolve resistance to antiviral drugs.
Unlike bacterial infections, populations of pathogenic viruses do not evolve resistance to antiviral drugs. The above statement is false.
Antiviral drug resistance is a growing concern in populations of immunocompromised patients because persistent viral replication and extended drug exposure select resistant types of viruses. By correlating distinctive viral mutations with resistance to different medications as identified by phenotypic testing, rapid diagnosis of resistance can be achieved. Optimizing host variables and medication delivery, choosing alternate treatments based on an understanding of the processes underlying resistance, and creating novel antivirals are all components of managing drug resistance.
