A serial dilution is performed on a culture of Saccharomyces cerevisiae (Brewer's yeast). A 1:10 dilution was performed in series seven times. You plated and spread 100 microliters of the fifth dilution to a YEPD agar plate to grow overnight. After incubation, you count 142 colonies on the plate. What was the viable count of the stock culture
Answers
Answer: CFU/mL = 14200 CFU/mL
Explanation:
Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.
To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.
So, the equation is:
CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)
100 microliters = 0.1 mililiter
1/10 = 0.1 (dilution factor)
Replacing the information from the question:
CFU/mL = 142 / (0.1 mL x 0.1)
CFU/mL = 14200 CFU/mL

Which phase of mitosis is shown at the
letter 'A'?
A Interphase
B Prophase
C Metaphase
D Anaphase
E Telophase
Answers
A newly created cell and its nucleus go through a series of modifications known as prophase and interphase in order to prepare for cell division. It is also known as the preparatory phase.
Exists the M phase?When a cell is in the M phase, it divides, first through nuclear division (mitosis), then through cytoplasmic division (cytokinesis). The DNA is replicated in the earlier S phase, and cohesins keep each replicated chromosome's two copies (known as sister chromatids) bound to one another.
Is the M phase the longest phase?Prophase is the first and longest phase of mitosis. Chromatin gathers into chromosomes and the nuclear envelope, which is the membrane that encloses the nucleus, disintegrates during prophase. DNA synthesis or replication takes place during the S phase of a cell cycle, which happens during interphase and comes before mitosis or meiosis. Before a cell starts mitosis or meiosis.

Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answers
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

0
B. RNA polymerase pulls apart the double helix.
C. RNA polymerase produces mRNA from DNA.
D. RNA polymerase reaches the beginning of a gene
Answers
Answer:
C
Explanation:
This is because the mRNA is produced from the template strand of the DNA.
RNA polymerase reaches the end of a gene. Therefore, option (A) is the correct answer.
What is RNA polymerase?RNA polymerase produces mRNA from DNA during transcription. After the RNA polymerase has moved along the DNA template strand and synthesized the complementary mRNA molecule, it will eventually reach the end of the gene being transcribed.
At this point, the RNA polymerase will dissociate from the DNA template, and the newly synthesized mRNA molecule will be released into the cytoplasm for further processing. Therefore, option A is the correct.

Select the most accurate of the following statements: Group of answer choices The vascular bundles of gymnosperms contain xylem only, whereas those of angiosperms contain both xylem and phloem Angiosperms produce specialized shoots bearing modified leaves to attract pollinators and protect gametes All gymnosperms have narrow, needle-like leaves whereas all angiosperms have broad, net-veined leaves Gymnosperm embryos are exposed to the elements, whereas the embryos of angiosperms are packaged with a food source inside a seed coat Gymnosperms have substantially more species than angiosperms
Answers
Answer:
The correct answer is - all gymnosperms have narrow, needle-like leaves whereas all the angiosperms have broad, net veined leaves".
Explanation:
Gymnosperm and angiosperm both possess xylem and phloem in their vascular bundles or vascular tissues for the transport of water and nutrients or minerals respectively.
Angiosperm or the flowering plants are the largest groups of all plant groups and more diverse than other even gymnosperms are less diverse and fewer in number in comparison to angiosperm.
All gymnosperms consist of narrow, needle-like leaves and in angiosperms, leaves are broad, net veined.
Both gymnosperms, as well as angiosperms, have xylem and phloem throughout their vascular tissues just to carry moisture and nutrients as well as rare earth minerals.
Angiosperms, or blooming plants, seem to be the most diverse as well as numerous vegetation groupings. Gymnosperms, on the other hand, have become less diverse but also numerous in contrast to angiosperms.Thus the above statement is correct.

1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.

The cell in the leaves of a plant that contains white patches will most likely be unable to trap the Sun’s energy through photosynthesis.
What is photosynthesis?Photosynthesis is the process whereby cells of a green plant obtain nutrition by utilizing energy from sunlight.
Photosynthesis takes place in an organelle of the cell called chloroplast. The chloroplast contains a pigment called chlorophyll that traps the energy from sunlight.
However, when the leaves of a plant are covered with white patches, this impedes the chloroplast from being able to trap the Sun’s energy through photosynthesis.

The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.
Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.
Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.
Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.

That environment which increases the activity of enzyme is considered suitable temperature for the enzyme and the temperature at which the activity of enzyme amylase is minimum is considered as bad temperature for the enzyme.
