Mention the name of four groups of important pathogenic E. coli? Can TBX medium be used to recover all types of nonpathogenic and pathogenic E. coli? Support your answer by giving an example.
Answers
The four groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic and enteroinvasive groups. These groups can best be isolated and recoved through luria broth.
What is Escherichia coli?The pathogenic E. coli or Escherichia coli serotypes are grouped on the basis of their mechanism of causing symptoms in humans. The six groups of pathogenic E.coli are enteropathogenic, enterotoxigenic, verocytotoxigenic, enteroinvasive, enteroaggregative and diffusely adherent E. coli.
Luria broth (LB) is one of the most commonly used growth medium for E. coli. It promotes fast growth of the organism and also provides good plasmid yields, making it an excellent choice for most laboratory applications, especially the small-scale plasmid preps.

In mice, the allele for gray fur (G) is dominant to the allele for brown fur (g). The allele (L) for long tail is dominant to the allele (l) for short tail. A cross is made between two mice that are heterozygous for gray and long tail. What is the expected phenotype ratio of the offspring?
Answers
Answer:
Explanation:
In this cross, the two parent mice are heterozygous for both the fur and tail traits, which means that they have the genotypes GgLl. The offspring of this cross will have a 1/4 chance of inheriting a GgLl genotype, a 1/4 chance of inheriting a Ggll genotype, a 1/4 chance of inheriting a ggLl genotype, and a 1/4 chance of inheriting a ggll genotype.
The expected phenotype ratio of the offspring will depend on which traits are dominant and which are recessive. In this case, the G allele is dominant and the g allele is recessive for the fur trait, and the L allele is dominant and the l allele is recessive for the tail trait. Therefore, the expected phenotype ratio of the offspring will be as follows:
Phenotype Ratio
Gray, long tail: 1/4
Gray, short tail: 1/4
Brown, long tail: 1/4
Brown, short tail: 1/4
This means that the expected phenotype ratio of the offspring is 1:1:1:1, or a 1:1 ratio of gray to brown fur and a 1:1 ratio of long to short tails.

2. How does the shape of a plant cell differ from that of an animal cell?
3. What is the function of the chloroplasts?
4. What is the function of the vacuole?
Answers
Answer:
1) Chloroplasts and Cell Wall
2) Plant cells typically have a rectangular or cube-shaped form, with a rigid cell wall on the exterior. Animal cells, on the other hand, tend to be round and lack a cell wall. Furthermore, plant cells contain chloroplasts, which are not present in animal cells.
3) Chloroplasts are the places within plants where photosynthesis takes place, where light energy is used to turn carbon dioxide and water into oxygen and sugar. Additionally, chloroplasts are responsible for the creation of food in plants through the process of photosynthesis.
4) The vacuole is an organelle located in the cytoplasm of eukaryotic cells that is enclosed by a membrane. Its main purpose is to store water and other molecules like proteins, carbohydrates, and ions. This organelle contributes to cell shape and turgor pressure, as well as regulating metabolism. Furthermore, vacuoles are involved in the digestion and recycling of cellular debris.

What is the relationship between the components of TLC (total lung capacity)?
Answers
Answer:
The total lung capacity (TLC) is the maximal volume of gas in the lungs after a maximal inhalation; thus it is the sum of the RV, ERV, VT, and IRV. TLC is approximately 6 L for a healthy 70-kg adult. The vital capacity (VC) is the maximal volume of gas exhaled during a forced exhalation after a forced inhalation.
This relationship calculates as the total lung capacity equaling the sum of functional residual capacity and the inspiratory capacity or as the equation: TLC = FRC + IC. The FRC is only measurable by plethysmography, nitrogen gas washout, or helium gas dilution methods, or using computed tomography (CT).

Answers
Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.
Catabolic reactions occur within cells during cellular respiration. It is a biochemical process by which waste materials are removed and nutrients are broken down to generate energy, which is then stored in the form of ATP. The process of aerobic respiration needs oxygen.The Krebs cycle, also known as the citric acid cycle, is the last step of oxidation for amino acids, lipids, and glucose.Other than glucose, many animals rely on other substances for energy.Protein's metabolic byproduct, amino acids, are deaminated and converted to pyruvate and other Krebs cycle intermediates.They begin the cycle and are broken down, for example. On deamination, alanine turns into pyruvate, glutamate into -ketoglutarate, and aspartate into oxaloacetate.Acetyl CoA is created when fatty acids are -oxidized and enters the Krebs cycle. It is the primary mechanism through which cells produce ATP. Complete nutrient oxidation results in the production of a significant amount of energy.To know more about glucose check the below link:
