Explain how elevated insulin level and suppressed c-peptide level strongly supports exogenous insulin administration, as opposed to overproduction of insulin in such cases of endogenous insulin overproduction as insulinoma or treatment with sulphonylurea

Answers

Equimolar amount of insulin and C peptide are usually released into the body system circulation under normal circumstances. A large fraction of circulating insulin is typically rapidly remove by the liver while the liver clear only a negligible amount of C peptide. C peptide is primarily cleared by the kidney at a lower metabolic clearance rate.
Normally the, C peptide level increases when the pancreatic secretion of insulin increases and vice versa. Therefore, exogenous administration of insulin results in an increase in insulin level without a corresponding increase in C peptide level. On the other hand, both insulin and C peptide levels are elevated in patients with insulinoma.

Explain what the results indicate about the new strain of bacteria produced when both strains of
e. coli were mixed together.

Answers

In the experiment attached to this question, there are two different strains of E coli which are resistance to different antibiotics. E coli 1 has a gene that is extracted from chromosomal DNA and which code for resistance to streptomycin. Ecoli 2 has a gene that is extracted from plasmid DNA and which code for resistance to ampicillin.
When these two strains of E coli were mixed together, they produce a new stain of E coli which is resistance to both ampicillin and streptomycin. Because of this, the new strain was able to grow on all the plates which contain these antibiotics.

The experiments with E. coli and bacteriophages demonstrate the occurrence of genetic recombination and transformation, leading to new bacterial phenotypes such as antibiotic resistance. These results showcase the bacteria's ability to gain genetic material and express new traits, emphasizing the mechanisms behind bacterial evolution and trait dissemination.

The results from various experiments with E. coli strains and bacteriophages indicate genetic recombination and transformation events that lead to the creation of new bacterial strains with different genetic material. For instance, when E. coli strain B is infected by both h* and h strains of the T2 bacteriophage, four different kinds of plaques appear, indicating genetic mixing. The appearance of new phenotypes due to recombination suggests that DNA from each parental bacteriophage type has exchanged genetic material within the bacterial cell.

In another scenario, when E. coli is coinfected with two different rII mutants, it demonstrates that recombination can also occur between two viral genomes within a host bacterial cell. Similarly, the transformation experiment where E. coli is mixed with a plasmid carrying ampicillin resistance, results show that some bacterial cells incorporate external DNA, leading to the expression of new traits such as antibiotic resistance.

The experiments underscore the fundamental principles of bacterial genetics, such as the capability of bacteria to undergo genetic changes resulting in phenotype alterations through processes like recombination and transformation. These findings are crucial in understanding bacterial evolution and the spread of traits such as antibiotic resistance.

How were species affected by the break up of Pangea

Answers

Final answer:

The breakup of Pangea affected species in terms of their distribution worldwide and in certain regions of the planet. Biogeography explains the geographic distribution of organisms based on evolution and tectonic plate movement. Fossil evidence, like Glossopteris fossils, supports the impact of the breakup on species.

Explanation:

Species were affected by the breakup of Pangea in the way that broad groups of species that evolved before the breakup are distributed worldwide, while groups that evolved after the breakup are found in only certain regions of the planet. This is known as biogeography, which explains the geographic distribution of organisms based on evolution and tectonic plate movement over geological time.

For example, the unique flora and fauna in the northern continents formed from the supercontinent Laurasia, while the flora and fauna in the southern continents formed from the supercontinent Gondwana. The presence of specific plant families, like Proteaceae, in Australia, southern Africa, and South America can be explained by their presence before the breakup of Gondwana.

Glossopteris fossils found in rocks across continents like Antarctica, Australia, South America, Africa, and India before the breakup of Pangea provide further evidence of how species were affected by the breakup.

how could decaying leaves affect the rocks in soil underneath them

Answers

Leaves release acid and can decay things, acid can break down the rocks and acid can go deep in the rocks crack and can make large cracks even breaking them apart.
Final answer:

Decaying leaves affect the rocks in the soil by contributing to soil composition, aiding decomposers in recycling nutrients, and causing chemical weathering of rocks due to acidic compounds produced during decomposition. They also help insulate the soil, impacting physical soil structure.

Explanation:

Decaying leaves can affect the rocks in the soil underneath them through various biological and chemical processes. Firstly, as leaves decompose, they become part of the soil's organic matter, which contributes to soil composition and health. This organic matter is broken down further by decomposers such as fungi and bacteria, a process essential for recycling nutrients back into the soil.

These nutrients include vital elements like nitrogen, phosphorus, and potassium, which are key for plant growth. Moreover, the decomposition process can result in the production of acidic compounds. These acids can contribute to the chemical weathering of rocks, which slowly breaks them down and releases minerals into the soil, enhancing fertility.

In addition to chemical effects, the physical presence of a substantial layer of leaf litter provides insulation for the soil, moderating temperature fluctuations and maintaining moisture levels. This can indirectly influence rock fragmentation as roots seek out nutrients and microorganisms thrive in the hospitable environment that leaf litter creates.

D) Plant cells are rectangular because they are all connected within a plant, while animal cells never come in contact with each other.

Answers

C) Animal cells vary in shape because they have different functions, while plant cells are rigid to help plants grow upright. 

Answer:

C) Animal cells vary in shape because they have different functions, while plant cells are rigid to help plants grow upright.

Explanation:

Because the animal organism is more complex and has more functioning mechanisms than the plant organism, animal cells have a great diversity in size, shape and function. The size and shape of animal cells is directly related to the function it exhibits. On the other hand, plant cells usually have the rectangular shape bounded by the cell wall, which is a thick, unyielding layer that surrounds the cell. This shape is important to allow the inflexibility of cells and their vertical growth.

For this reason, we can say that the correct answer to your question is the letter C.

Periglacial areas can be enviroments where freezing and rethawing significantly restructure or modify the surrounding environment.

Periglacial

Stone rings, pingoes, and rock glaciers and other periglacial activity became more common during ice ages.

Periglacial activity is a geomorphic process that occurs due to periodical defrosting of snow in regions of permafrost (frozen ground), the runoff which becomes frozen again in ice wedges and other structures. During periglacial activity, there is a regular fluctuation of air temperature across zero degree Celsius, and the process influences the landscape in a significant way.

The discovery that some proteins are composed of more than one polypeptide chain and that different polypeptide chains are encoded by separate genes became the _____.

Answers

The discovery that some proteins are composed of more than one polypeptide chain and that different polypeptide chains are encoded by separate genes became the one gene- one polypeptide hypothesis. 
Father of this theory is the geneticist George Beadle from United States. He stated it in 1945 .
Final answer:

The concept that proteins are composed of more than one polypeptide chain and different polypeptide chains are encoded by separate genes, is known as the central dogma of molecular biology. This came from the field of molecular genetics, following the discovery of the one gene-one polypeptide hypothesis, which states that individual genes encode specific polypeptide chains within proteins.

Explanation:

The discovery that some proteins are composed of more than one polypeptide chain and that different polypeptide chains are encoded by separate genes became the central dogma of molecular biology. The one gene-one polypeptide hypothesis, established by Beadle and Tatum, states that a single gene controls the production of a single protein, but later revisions acknowledged that each gene can encode a different polypeptide chain within a protein as observed in many cases. This was a result of understanding the processes of transcription and translation due to significant scientific findings.

Transcription is the process that involves the reading of a gene composed of DNA to produce a molecule of RNA. This is then translated into a protein through a process called translation, where the sequence of nucleotides in the DNA is used as a template to synthesize a complementary RNA sequence. The RNA sequence is then utilized by ribosomes to assemble the specific set of amino acids, resulting in the formation of a polypeptide chain. These chains can then come together to form the final protein product governed by the information in the original DNA sequences.

Some of the key experimenters who contributed to this understanding were Frederick Griffith, Oswald Avery, Colin McLeod, and Maclyn McCarty who demonstrated that DNA was the hereditary material. Later, Alfred Hershey and Martha Chase confirmed this revelation. Finally, the discovery of nucleotides in DNA further strengthened the belief that proteins were not the vehicles for hereditary information.

How do cells use energy? select all that apply?

Answers

what are the options? 

Final answer:

Cells use energy to perform various tasks such as molecule synthesis, signal transportation, and movement. They obtain energy by metabolizing nutrients, which involves anabolic and catabolic reactions, and store it as ATP. Plants produce energy-rich sugars through photosynthesis, which are used by themselves and other organisms.

Explanation:

How Cells Use Energy

Cells require energy for virtually all processes, including the synthesis and breakdown of molecules, transporting signals such as hormones and neurotransmitters, and motility using structures like cilia and flagella. Energy comes primarily in the form of Adenosine Triphosphate (ATP), the cellular 'currency' of energy. Cells obtain energy through the metabolism of nutrients, like sugars, which are broken down in a series of anabolic and catabolic reactions. These metabolic processes are part of a broader field known as bioenergetics, which is the study of energy flow through living systems.

During anabolic reactions, cells use energy to build complex molecules from simpler ones, whereas catabolic reactions release energy when complex molecules are broken down. Plants, for instance, capture energy from sunlight during photosynthesis to create sugars that can later be used by both plants and other organisms. Overall, cells are efficient at harnessing energy from various sources and utilizing it to maintain their structure and function.
