Which of the following sets of metabolic processes can be used by microorganisms but cannot be performed by plants or animals? Select one answer.
(a) CO2 fixation, nitrogen fixation, ammonia assimilation
(b) Nitrification, denitrification, CO2 fixation
(c) Methanogenesis, denitrification, sulfide oxidation
(d) Ammonia assimilation, urea mineralization, oxygenic photosynthesis
(e) Oxygenic photosynthesis, sulfate reduction, sulfide oxidation
The set of metabolic processes that can be used by microorganisms but cannot be performed by plants or animals is (c) Methanogenesis, denitrification, sulfide oxidation.
Microorganisms have a diverse range of metabolic capabilities that allow them to perform certain processes that are not typically found in plants or animals. The set of metabolic processes in option (c) Methanogenesis, denitrification, sulfide oxidation is one such example.
Methanogenesis is the process by which microorganisms produce methane gas as a metabolic byproduct. This process is carried out by specific groups of microorganisms known as methanogens, which are capable of utilizing various carbon sources to produce methane.
Denitrification is a process where certain microorganisms convert nitrates (NO3-) into nitrogen gas (N2). This process occurs under anaerobic conditions and is important for the nitrogen cycle, as it helps to return nitrogen gas to the atmosphere.
Sulfide oxidation involves the oxidation of sulfide compounds, such as hydrogen sulfide (H2S), by microorganisms. This process is significant in environments where sulfide is present, such as sulfur-rich sediments or hydrothermal vents.
Plants and animals, on the other hand, do not possess the specific enzymatic pathways or physiological adaptations required to carry out these metabolic processes. Thus, option (c) is the correct answer as it includes metabolic processes that are unique to microorganisms.

An organism's home is known as its habitat, and its function in its environment is known as its niche. While niche focuses on how the creature effects the environment, habitat focuses on how the environment impacts the organism.
What about species?A group of things that share the same kind and name: kind. A group of related organisms with the capacity to bear viable offspring that falls below the genus level and is designated by a two-part scientific name. A group of plants or animals that may reproduce together and have similar characteristics is referred to as a species.A collection of people with similar traits who can interbreed to create fruitful offspring is how species are frequently defined. Alpaca - Vicugna pacos are two examples. A group of creatures that can naturally reproduce with one another and generate viable progeny is sometimes referred to as a species. However, classifying a species can be challenging and even contentious. The billions of people on the planet now are all members of the same species, Homo sapiens. Human beings differ among themselves, just like other species do, in terms of everything from size and shape to skin tone and eye color. The two-part name that Linnaeus invented is still used today and is currently presented in either Latin or Greek. It was originally used for plants and then later for animals. The first identifies the larger group, known as a genus, to which the plant belongs, while the second refers to the plant itself as a species.Learn more about species here:

majority of atp in aerobic respiration is generated thanks to nadph produced during
Majority of atp in aerobic respiration is generated thanks to nadph produced during the light-dependent reactions of photosynthesis.
NADPH is an electron carrier that donates electrons and protons to the electron transport chain during cellular respiration. This donation drives the production of ATP through the process of oxidative phosphorylation, which occurs in the mitochondria. The energy released by the oxidation of NADPH is used to power the pumping of protons across the inner mitochondrial membrane, creating a proton gradient that drives ATP synthase to generate ATP. Therefore, the NADPH produced during photosynthesis is crucial in powering the production of ATP during aerobic respiration, making it a vital component in maintaining energy balance in cells.

1. How do bacteria differ, and what is happening to the bacteria when they are exposed to antibiotics in their environment? Write a full paragraph for more.... Will give brainliest
Answer:
Bacteria have the ability to develop resistance by using enoded instructions by their DNA. Generally, the resistance genes present within plasmids. In this mechanism, they are able to share their DNA and make other bacteria resistant too.
This mechanism takes place by avoiding the expression or effectiveness of antiboitics designed to kill or prevent these strains. The strains that are able to survive, share their DNA with others and increase their numbers.
Proteomics is the study of the number of different proteins that a gene produces. Why might this be a more complete snapshot of human genetics than genomics? в то = = т т.
Proteomics is the study of the entire set of proteins produced by a cell or organism while genomics is the study of the complete set of genes present in an organism.
Proteomics gives a more complete snapshot of human genetics than genomics because proteins are the workhorses of the cell and carry out most of the biological functions in an organism. Proteins are responsible for gene expression and protein function, so by studying proteins, we can gain a more comprehensive understanding of how genes contribute to the phenotype.
Proteomics is the large-scale study of proteins. It is a multidisciplinary field that includes molecular biology, biochemistry, biophysics, and other disciplines. Proteomics research aims to identify all of the proteins that an organism produces, understand their function and structure, and investigate how they interact with each other and with other molecules in the cell. Proteins are vital building blocks of the cell and perform a variety of functions. They are involved in everything from gene expression to immune function to metabolism, and they play a key role in virtually every biological process that occurs in the body. By studying proteins, researchers can gain a better understanding of how the body works at a molecular level.

To validate your hypothesis, conduct an experiment. If your idea is accurate, every time a scientific experiment has been conducted, it might have a positive outcome.
If your experiment doesn't work, you should retry it with a different hypothesis based on the information you learned from your first attempt.
An experiment is a method used to verify or disprove a hypothesis, as well as to assess the effectiveness or likelihood of something that has never been tried before. By showing what happens as a result of manipulating a certain factor, experiments shed light on cause-and-effect relationships.
While a control group doesn't receive the treatment, an experimental group also known as a treatment group, does and the effects of that treatment are then observed.

which of the following is false concerning the net atp (atp equivalent) yield/glucose? it is 2 in the kreb's cycle. it is 34 in the electron transport system oxidative phosphorylation processes in bacterial aerobic respiration
The false statement concerning the net ATP (ATP equivalent) yield/glucose is that it is 2 in the Kreb's cycle. The Kreb's cycle, also known as the citric acid cycle, is responsible for producing electron carriers (NADH and FADH2) that enter the electron transport chain for ATP production.
However, the Kreb's cycle only produces a small amount of ATP through substrate-level phosphorylation (2 ATP per glucose molecule). The majority of ATP production occurs through oxidative phosphorylation in the electron transport system, which occurs after the Kreb's cycle.
In bacterial aerobic respiration, the net ATP yield/glucose through oxidative phosphorylation is 34, which is a much larger yield than what is produced through substrate-level phosphorylation in the Kreb's cycle. Therefore, the false statement is that the net ATP yield/glucose is 2 in the Kreb's cycle.

A farmer working on a piece of machinery gets his shirtsleeve caught in a moving piece of the equipment. His shirt is sliced, and a sharp
blade covered in mud slices through his upper arm. He attempts to control the bleeding and immediately seeks medical attention. After 3
days, he develops a fever and his arm becomes extremely swollen and painful. Pulling back the bandages, he finds that the wound has
become blackened and is leaking bloody fluid. Microscopic analysis of the fluid reveals the presence of gram-positive bacilli.
a. Discuss what condition the patient is suffering from and the likely causative agent of this infection.
b. Explain how the patient contracted this pathogenic microbe and what virulence factors contributed to the pathogenesis seen at
the wound site.
c. In addition to antibiotics, the physician prescribes hyperbaric therapy. Describe what this treatment involves and how it could be
therapeutic to this patient
Based on the bacterial characterisation, we can determine that this is a gram-positive bacterium, and based on the symptoms and biopsy, we can also conclude that it is most likely bacilli.
From the evidence obtained from bacterial characterization, it is possible to allude the symptoms to a gram-positive bacterium. It is also plausible to conclude that it is most likely bacilli based on the symptoms and biopsy. It is obvious he had a fever, a swollen arm, and black skin which furthers supports the bacterium assumption. The bacterium responsible was most likely from Clostridium perforation. The bandage kept on for some days allowed the bacterial growth resulting in gangrene. To be sure of these assumptions, more testing, however, are required to identify this bacterium as the source of the illness. Necrosis or necrosis of muscle tissue distinguishes gangrene. This infection is mainly acquired through wounds and contact with soil particles, as we noticed in the patient's arm.
