plz solve it within 30-40 mins I'll give you multiple upvote handwritten solution plz in this chapter we explored exponentialfunctions, which can be used for, amongother things, modeling growth patternssuch as those found in bacteria. we alsoinvestigated logarithmic functions, whichare closely related to exponential functions.Both types of functions have numerousreal-world applications when it comes tomodeling and interpreting data. Writeabout one or two examples of growth anddecay and how it relates to exponential andlogarithmic functions.

Suppose that you were tasked with 4 cultures of a specific Bacteria Species in Luria Broth medium: (1) culture A – cells are in lag phase; (2) culture B – cell in log phase; (3) culture C – cells in stationary phase; and culture D – cells in decline phase. Imagine that you observe the growth rates of each culture in a fresh sterilized LB medium. Now, plot the outcome growth curves of cultures A, B, C and D in a single graph.
Consider the desired phenotype pattern of candidates that we wish to advance into experiments in Week 5 and beyond. If the growth patterns illustrated below are observed in your Week 4 results, which of the candidates would you select for further analysis? Select all that apply. Candidate A B A B C с = vigorous growth on this medium = impaired/slow growth on this medium = no growth on this medium SC-H B SC-K A B YP Gal
Differential centrifugation can be improved through the use of a density gradient. What is the purpose of this, and how does it work?
Use the following passage to answer 2 consecutive questions. A urine specimen was collected in a container and placed on the central desk for delivery at 10:00 am. The specimen is not sent to the lab until 5 hours later (3:00 pm). The sample time was marked by the central clerk as collected at 4:00 pm. The bacterial species has a generation time of 30 minutes at room temperature. There are 100 bacterial cells/ml at the time of collection (10:00 am). The laboratory will cite a bacterial infection at more than 1000 bacterial cells/ml.
Consider a batch culture of sphere-shaped bacteria in a growth medium or broth, in which the mean cell diameter of the bacteria is 2.0 μm (micron). Show all your calculations and assumptions in answering the questions below: What is the volume of one of these sphere-shaped cells, expressed in liters? If there are 3 x 10^12 cells in one liter of this culture broth, what percentage of the volume is occupied by bacteria and what percentage is occupied by the cell culture broth (water only)? If the cells contain 80% water, what is the dry cell concentration, expressed as “grams dry weight/Liter of broth”? You should assume that the density of the cells dry mass is approximately 1.0 gr/cm3
Which of the following is the best definition of generationtime?(a) The length of time it takes for lag phase to occur(b) The length of time it takes a population of cells to double(c) The minimum length of time it takes a cell to divide(d) The length of time a culture stays in stationary phase(e) The length of time it takes log phase to occur

(a) With the aid of a diagram, plot a sigmoid curve for human growth and label the phase that showing the growth is happening rapidly. Briefly explain the phase that has been labelled in (a).
Analyze the following experiment and answer the questions that follow. Suppose that the growth behavior of a native catfish is to be characterized. To understand the growth behavior implies the possibility of growing the fish in an aquaculture. It is possible to manage the growth of fish in a controlled condition. Accomplish the following. 1. Identify the following: a. Process? b. Input? c. Controllable factors? d. Uncontrollable factors? e. Output? Response variable? 2. Draw the IPO diagram. 3. Make a simple experimental design using the 5-step process, except step 4.
is there a correlation between one medium supporting growth at a wide set range or organismal growth and another supporting little to no organismal growth and if the terms defined medium and undefined medium? if so, what is it? If not, attempt to explain the relationship you observe?
