extrachromosomal dna is critical to the antibiotic resistance found in microorganisms, how do these dna elements account for this phenomena?

Answers

Answer 1

Extrachromosomal DNA is critical to the antibiotic resistance found in microorganisms. These DNA elements account for the phenomena by providing resistance genes that can be shared among bacteria, allowing them to survive exposure to antibiotics.

What are Extrachromosomal DNA?

Extrachromosomal DNA are also known as plasmids, and these can be passed between bacteria through a process called conjugation. This allows resistance genes to be shared between bacteria, increasing the prevalence of antibiotic-resistant strains. In addition, some extrachromosomal DNA contains genes that produce enzymes that can break down antibiotics, rendering them ineffective against the bacteria carrying these genes. This is known as enzymatic resistance.

Extrachromosomal DNA can also provide bacteria with the ability to pump antibiotics out of their cells more effectively, preventing the antibiotics from reaching their intended targets within the bacteria. This is known as efflux-mediated resistance. In summary, extrachromosomal DNA plays a critical role in the development of antibiotic resistance in microorganisms. By providing resistance genes that can be shared between bacteria, producing enzymes that break down antibiotics, and increasing the ability of bacteria to pump antibiotics out of their cells, extrachromosomal DNA allows bacteria to survive exposure to antibiotics.

What is a similar structure in different species that evolved separately called?

Answers

The similar structure in different species that evolved separately is called a convergent structure.

The term “convergent structure” refers to the process by which distinct species with different ancestors develop similar structures, either through adaptation to similar environmental conditions or similar ecological roles.

This phenomenon, known as convergent evolution, typically results in different organisms developing similar adaptations to solve the same problem.

Both structures have evolved to perform the same task (flight), and both have independently evolved to do so due to selective pressure in a specific habitat.

A similar structure, shared by different species, is termed homology when it is derived from a common ancestor, and analogy when it is not.

The similarity between bat wings and bird wings is a classic example of analogy, since these structures did not evolve from a common ancestral structure but instead emerged independently in response to selective pressure.

describe how two medical conditions might be helped by biofeedback therapy.

Answers

Biofeedback therapy is a type of treatment that involves using electronic monitoring equipment to provide patients with real-time feedback about their physiological responses.

By gaining awareness and control over their bodily functions, patients can learn to manage symptoms associated with certain medical conditions. Here are two examples of how biofeedback therapy can help with specific medical conditions:

Migraine headaches: Biofeedback therapy can help reduce the frequency and severity of migraine headaches. During biofeedback sessions, patients are taught to recognize the physiological signs that often precede a migraine attack, such as muscle tension and increased heart rate. By learning to recognize and control these responses, patients can reduce the intensity and frequency of migraines.

Urinary incontinence: Biofeedback therapy can help people who have difficulty controlling their bladder muscles. During biofeedback sessions, patients are taught to recognize and strengthen the pelvic floor muscles that are responsible for bladder control. By gaining control over these muscles, patients can improve bladder function and reduce urinary incontinence.

In both cases, biofeedback therapy can help patients gain greater awareness and control over their physiological responses, leading to improved symptom management and overall quality of life.

dna choose... joins choose... to synthesize a new choose... dna strand.

Answers

DNA polymerase is an enzyme that joins nucleotides to synthesize a new DNA strand during DNA replication.

The process begins with the separation of the double-stranded DNA molecule into two separate strands by an enzyme called helicase. One of the strands serves as a template for the synthesis of a new complementary strand. DNA polymerase reads the template strand and matches complementary nucleotides to it, adding them one by one in the 5' to 3' direction.

As each nucleotide is added, DNA polymerase catalyzes the formation of a phosphodiester bond between the 3' end of the growing DNA strand and the 5' phosphate group of the new nucleotide. This process continues until a complete new DNA strand has been synthesized.

Who are the 2 scientists that influenced Darwin's theory of evolution?

Answers

The two scientists that influenced Darwin's theory of evolution are Thomas Malthus and Charles Lyell.

Evolution is defined as the process of gradual development or changes of an organism's features over time as a result of changes in genetic and environmental factors. The theory of evolution, as proposed by Charles Darwin, is the most widely recognized scientific theory that explains how organisms change and adapt to their surroundings.The theory of evolution proposes that all species on Earth have evolved from a single common ancestor through a process of natural selection. According to Darwin's theory of evolution, organisms that possess favorable characteristics for their environment are more likely to survive and pass on those characteristics to their offspring. Those organisms that are less well-suited to their environment will not survive and their traits will eventually be lost over time.In the development of his theory, Darwin was influenced by the works of several scientists including Thomas Malthus and Charles Lyell. Darwin incorporated their ideas into his own to produce the theory of evolution. Malthus argued that human population growth was limited by food supply, and this idea provided Darwin with the concept of natural selection. Lyell's work in geology proposed that the Earth's surface has been shaped over a long period of time by gradual processes, and this helped Darwin to understand the concept of slow changes in species over time.

mouth-shaped openings in the epidermis of plants are called

Answers

Stomata are the mouth-shaped openings in the epidermis of plants. These tiny pores are surrounded by two specialized guard cells that control the opening and closing of the stomata.

The guard cells are responsible for regulating the exchange of gases and water vapor between the plant and its environment. When the stomata are open, carbon dioxide can enter the plant and oxygen and water vapor can exit. This process, known as transpiration, is essential for plant growth and survival. Stomata are typically found on the leaves of plants, although they can also be found on stems and other parts of the plant. The number and distribution of stomata on a plant can vary depending on the species, environmental conditions, and other factors. In general, plants that live in dry or arid environments tend to have fewer stomata, while those that live in wetter environments tend to have more. Additionally, some plants have specialized stomata that are adapted to specific environmental conditions. For example, certain plants that live in saline environments have evolved stomata that are able to exclude salt from entering the plant. Overall, stomata play a crucial role in the life of plants, allowing them to breathe and absorb the nutrients they need to grow and thrive.

What describes the daughter cells produced during meiosis?

Answers

The types of daughter cells produced during meiosis are Genetically distinct due to crossing over.

Daughter cells are the cells that divide from the mother cell during cell division. In somatic cells, the process of mitosis results in the production of two daughter cells, whereas the process of meiosis results in the production of four daughter cells in germ cells.

Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary. The number of chromosomes is restored in the progeny when the sperm and egg combine to create a single cell during reproduction.

The original cell's cytoplasm is now split into two daughter cells as the cell goes through a process known as cytokinesis. Only one set of chromosomes, or half as many as the parent cell's total number, are present in each haploid daughter cell.

In what type of axon does saltatory conduction occur?a. myelinatedb. unmyelinated

Answers

Answer: myelinated

Explanation:

Saltatory conduction occurs only on myelinated axons.

Final answer:

Saltatory conduction occurs in myelinated axons. The myelin sheath on these axons promotes faster signal propagation by allowing action potentials to 'jump' from one node of Ranvier to the next.

Explanation:

Saltatory conduction occurs in myelinated axons. Myelinated axons are axons that are covered by a fatty substance known as myelin. This myelin sheath insulates the axon and increases the speed at which electrical impulses, or action potentials, are transmitted along the axon. During saltatory conduction, the action potential 'jumps' from one node of Ranvier to the next. These nodes are the small gaps in the myelin sheath along the axon. Compared to unmyelinated axons, where the action potential propagates in a continuous wave, the 'jumping' action in myelinated axons leads to faster signal propagation.

What is feedback regulation of endocrine system?

Answers

To ensure that these processes are properly regulated, the endocrine system employs a feedback mechanism to regulate hormone levels.

What is Feedback regulation?

Feedback regulation is the process by which hormone levels are regulated in the endocrine system. Hormones are chemical messengers that travel throughout the body to regulate various physiological processes. This feedback mechanism operates through a series of feedback loops that monitor hormone levels in the blood and adjust hormone secretion accordingly.

Hormones are chemical messengers that are produced by the endocrine glands and secreted into the bloodstream. These hormones travel to target cells in the body, where they bind to specific receptor proteins on the surface of the cell. The binding of a hormone to its receptor triggers a series of signaling pathways within the cell that ultimately lead to changes in gene expression and other cellular processes.

Feedback regulation is critical to maintaining proper hormone levels in the body. When hormone levels become too high or too low, the feedback mechanism responds by adjusting hormone secretion to restore balance. This ensures that the body's physiological processes remain properly regulated and functioning efficiently.

how does the life cycle of an average-sized star differ from the life cycle of a high-mass star?

Answers

The life cycle of an average-sized star like the sun starts with the collapse of a cloud of gas and dust under the force of gravity.

As the cloud collapses, it becomes more massive and heats up, eventually reaching a temperature and density that allow nuclear fusion reactions to occur in its core. These fusion reactions convert hydrogen into helium, releasing energy in the form of light and heat.

This phase called the main sequence, can last for billions of years, during which the star is stable. In contrast, high-mass stars have a much shorter lifespan and a more explosive end. Due to their high mass, they burn through their fuel at a much faster rate, causing them to evolve more quickly.

They also undergo a series of nuclear fusion reactions, creating heavier elements in their cores. Eventually, these stars will run out of fuel, and the core will collapse. This collapse triggers a supernova explosion that can be more than 10 times brighter than an average-sized star. After the explosion, the core may collapse further, forming a black hole or a neutron star.
