The colony-forming unit (CFU) is an indication of viable clonogenic cell populations expressed in CFU/mL. CFUs represent the number of cells that are still alive and sufficient for them to create tiny colonies.
CFUs are an estimate of the number of progenitors present in a given cell population, if an individual cell has the capacity to multiply and divide into adult blood cells under certain growth situations, it will form a single colony.
The Plate and dilution factor is:
[tex]Plate - \ dilution factor1 - 10^42 - 10^13 - 10^24 - 10^1[/tex]
Plate 3's individual dilution factor will alter because only 0.1 ml of diluent is added instead of 1 ml. As a result, the particular dilution factor of plate 3 rose from 10 to 100.
The original sample of CFUs is;
[tex]CFUs = Number\ of\ colonies \times Dilution \ factor \\\\\rm CFU= 49 \times10^8 \ cfu/ml[/tex]
So, the number of CFUs is [tex]49 \times10^8[/tex] cfu/ml.

Explain what paleomagnetism is and how it supports the theory of continental drift. *
Answer:
the branch of geophysics concerned with the magnetism in rocks that was induced by the earth's magnetic field at the time of their form. The record of the strength and direction of Earth's magnetic field (paleomagnetism, or fossil magnetism) is an important source of our knowledge about the Earth's evolution throughout the entire geological history. This record is preserved by many rocks from the time of their formation.

Scientists have found that mountain ranges from different continents show rocks that are similar in age and sequence. Based on these observations, what conclusions can be made. *
Line AB passes through points A (-3, 1) and B (3, 3) as shown on the coordinate grid. The
slope of the line is 1/3.
Which equations for line CD is PARALLEL to line AB and contains the point (6,5)?
Answer:
y=(1/3)x + (13/3)
Explanation:
since line cd is parallel to Ab gradient is same for both line.
Therefore equation of line cd
y= (1/3)x + c
6= (1/3)*5 +c
c = 6-(5/3)
c = 13/3

Refer to the graph that shows travel-time curves in the province of Batangas.The travel time shows that the P-S wave interval is about 5 minutes. What is the distance of the epicenter from the seismogram?
Answer:
Seismology is the study of earthquakes, their effects, and seismic waves. The location of an earthquake's epicenter (point on the earth's surface directly above the location of rupture or faulting) can be determined using information about two of these seismic waves.
Explanation:so easy
The waves created by an earthquake are used in determining the location of the earthquake
The distance of the epicenter from the seismogram is 3,000 km
The reason the given distance of the epicenter of the earthquake from the seismogram is correct is as follows;
The given parameter is as follows;
The P-S wave interval = 5 minutes
Required:
To find the distance of the epicenter
Solution:
The relationship between P-S wave interval and distance of the epicenter, is 1.5 minutes = 900 km
Therefore, given that the P-S wave interval, we have;
1.5 minutes = 900 km
The distance of the epicenter from the seismogram, d, given that the P-S interval is about 5 minutes, is given as follows;
[tex]d= \dfrac{900 \ km}{1.5 \ min} \times 5 \ minutes = 3,000 \ km[/tex]
Therefore;
The distance of the epicenter from the seismogram, d = 3,000 km

Which is a subcategory of a period? O A. Epoch O B. Era O C. Jurassic O D. Eon
The answer should be Epoch
Epoch is a subcategory of a period. Thus, option A is correct.
What is a time period?Time frame is the amount of time that a behavior lasts or a condition persists. Depending on the type of activity or situation under consideration, it may be plotted against time or in hundreds of thousands of years. The amount of time is how long it takes for a wave to pass a location after going through one full cycle.
A measure of time that is greater than a period but shorter than an eon. Period: A temporal interval that is longer than an epoch while short than an era. Epoch: A temporal interval that is longer than that of age but less than a period.
The post-time period is the one that is measured and is a subcategory. There is various sub-category of the time period that is present in a particular range.
