A 50 mL sample of soup was found to be contaminated with E. coli. A dilution of the soup was prepared by adding 14 mL of the soup to 20 mL of water. This was then diluted 1/60, and finally 10-3. Then .25 was added in to 2 plates. The first plate had a colony count of 72 and second had 65.
To do the dilution series does the 50 need to be added?
Answers
Answer:
The answer is "\(\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}\)"
Explanation:
The very first thing we must do is figure out where the plate was really a countable sheet. By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range. We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.
\(\to 72+ \frac{65}{2} = 68.5\)
We need to calculate its dilution factor for both the second item. Increase for all of this
All of the dilutions you also made:
\(\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}\)
\(\to \frac{14 \ ml \ soup}{14 \ ml} + 20\ mL\\\\\)
\(\to \frac{CFU}{mL} = \frac{Colonial \ number}{Dilution \ Factor \times Volume \ plated}\\\\\)
\(= \frac{68.5}{6.8 \times 10^{-6} \times 0.25 \ mL} \\\\ = 4.0 \times 10^7\)

breathing in physical phenomenon. what movement does happen when a person breathe in?
Answers
When a person breathes in, the diaphragm contracts and the lungs expand, creating a vacuum that draws air into the lungs. The air is then circulated through the lungs, where oxygen is absorbed and carbon dioxide is released.
What should know about the body parts that functions when you breath-in?The diaphragm is a vital muscle in inhaling (breath-in) and exhaling, separates the chest cavity from the abdominal cavity.
When the diaphragm contracts, it flattens and moves down. This increases the space in the chest cavity, which causes the lungs to expand. The lungs are elastic, so they expand when the space around them increases.

The light reactions produce ________, which are used in the Calvin cycle. The Calvin cycle produces ________, which are in turn used in the light reactions.
Answers
The light reactions produce ATP and NADPH, which are used in the Calvin cycle. The Calvin cycle produces glucose and other organic compounds, which are used in the light reactions.
The light reactions in photosynthesis produce ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which are used in the Calvin cycle. During the light reactions, light energy is captured by chlorophyll and other pigments, which initiates a series of reactions that generate ATP through photophosphorylation and NADPH through electron transport. These energy-rich molecules are then utilized in the Calvin cycle.The Calvin cycle, also known as the dark reactions or the light-independent reactions, takes place in the stroma of chloroplasts. It utilizes ATP and NADPH from the light reactions, along with carbon dioxide (CO2), to produce glucose and other organic molecules through carbon fixation. This process involves a series of enzymatic reactions, such as carbon dioxide fixation, reduction, and regeneration of the starting molecule, ribulose-1,5-bisphosphate (RuBP).Thus, the light reactions provide ATP and NADPH to the Calvin cycle, while the Calvin cycle produces glucose and other organic compounds that can be used as energy sources or for building cellular structures.For more such questions on Calvin cycle:

uses of biotechnology in washing powder making
Answers
Answer:
Here are some uses of biotechnology in the production of washing powders:
Enzymes: Enzymes are commonly used in washing powders to enhance the cleaning efficiency and remove various types of stains. Proteases, amylases, lipases, and cellulases are examples of enzymes used in washing powders. These enzymes break down protein-based, starch-based, lipid-based, and cellulose-based stains, respectively, into smaller fragments, making them easier to remove during the washing process.
Bio-surfactants: Surfactants are essential components of washing powders as they help to remove dirt and oil from fabrics. Biotechnology allows for the development of bio-surfactants, which are surfactants derived from biological sources, such as bacteria or yeast. These bio-surfactants are more environmentally friendly than traditional surfactants as they are biodegradable and have lower ecological impact.
Microbial Strains: Biotechnology can be used to isolate, characterize, and optimize microbial strains that produce enzymes or bio-surfactants. Microorganisms, such as bacteria and fungi, can be engineered or selected for their ability to produce specific compounds that enhance the cleaning performance of washing powders.
Genetic Modification: Genetic modification techniques can be employed to enhance the properties of microorganisms used in the production of enzymes or bio-surfactants. This allows for the creation of microorganisms with improved characteristics, such as increased enzyme activity or enhanced stability under varying conditions.
Fermentation Processes: Biotechnology facilitates the use of fermentation processes to produce enzymes and bio-surfactants at a large scale. Fermentation involves the controlled growth of microorganisms in bioreactors, where they produce enzymes or bio-surfactants through metabolic processes. This enables the efficient and cost-effective production of these ingredients for use in washing powders.
Explanation:
Explain how the earth itself is a system and describe an example of an interaction within this system.
Answers
One example of an interaction within the earth system is the carbon cycle. Carbon is a fundamental element that is essential for life on earth. It is present in the atmosphere as carbon dioxide, in the oceans as dissolved carbon, and in living organisms as organic compounds. The carbon cycle describes the movement of carbon between these different reservoirs.
During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into organic compounds. These compounds are then consumed by animals, which release carbon dioxide back into the atmosphere through respiration. When plants and animals die, they decompose, and their carbon-containing remains are buried in sedimentary rocks. Over time, these rocks are subducted and melted, releasing carbon dioxide back into the atmosphere through volcanic eruptions.
Human activities, such as burning fossil fuels, deforestation, and land-use changes, have disrupted the carbon cycle, leading to an increase in atmospheric carbon dioxide levels and contributing to climate change. This is an example of how human activities can have a significant impact on the earth's natural systems and the importance of understanding the interactions within the earth system to mitigate these impacts.
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
Answers
Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.
What is a dihybrid cross?A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.
Given,
Autosomal dominant = Bb (beard), W (black coat)
Autosomal recessive = B+ (beardless ), w (white coat)
Parent = B+Bb Ww male and B+Bb Ww female
The cross between the parent is attached to the image below.
From the cross, it can be said that:
9/16 bearded, black coat1/16 beardless, white coat3/16 beardless, black coat3/16 bearded, white coatFrom the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.
