greater prairie chickens once inhabited about every county in wisconsin. by 1930, however, it was estimated that only about 55,000 birds inhabited the state. in 1950, only about 2,500 birds remained in four isolated areas in the center of the state and by 1960 these birds declined in abundance to about half this size (~1,250 birds). since 1960 the number of birds has fluctuated around this level. it is estimated that greater prairie chickens have a generation time of about two years. data were obtained from the mitochondrial dna of historic (1951-1954) and contemporary (1998-2000) samples of birds from wisconsin. the average number of alleles per gene locus were significantly lower in the contemporary samples compared to the historic samples. (hint: having only two alleles per gene is rare in any population). a. using your knowledge of evolution and speciation, what is the most probable explanation for the allele differences observed in the prairie chickens from the 1950's to the 2000's?
Answers
Answer: The most likely explanation for the allele differences observed in Greater Prairie Chickens between the 1950s and 2000s is genetic bottleneck. This occurs when a population experiences a significant reduction in its total size, resulting in a decrease in the amount of genetic diversity within the population. This can lead to a decrease in the number of alleles per gene locus, as individuals may carry the same alleles more frequently due to the reduced gene pool. In the case of Greater Prairie Chickens, it is possible that the population experienced a genetic bottleneck in the late 20th century, resulting in a loss of genetic diversity and a decrease in the number of alleles per gene locus in contemporary samples compared to historic samples.

B
A amplitude
B) frequency
harmonics.
D) resonance
What’s this?
Answers
D) resonance is the correct answer. Amplitude refers to the maximum displacement of a vibrating object, frequency is the number of vibrations per unit of time, and harmonics are multiples of the fundamental frequency. While these concepts are related to vibration and sound, they do not specifically describe the transfer of vibration from a plucked guitar string to the body of the guitar.
The transfer of vibration from a plucked guitar string to the body of the guitar is known as resonance. Resonance occurs when an object vibrates at its natural frequency in response to the vibrations of another object. In the case of a guitar, when a string is plucked, it creates a specific frequency of vibrations. These vibrations are transmitted to the body of the guitar, which is designed to amplify and resonate with those vibrations.
Resonance is a fundamental concept in the physics of sound and vibrations. It occurs when two objects have the same natural frequency or a multiple of that frequency. In the case of the guitar, the body of the guitar is designed to have a resonant frequency that matches or is in harmony with the frequencies produced by the vibrating strings. This resonance enhances the sound produced by the strings, making it louder and richer.
The body of the guitar acts as a resonating chamber, amplifying the vibrations of the strings by reinforcing the specific frequencies that correspond to its natural modes of vibration. The vibrations of the strings transfer energy to the body of the guitar, causing it to vibrate sympathetically. This additional vibration of the body resonates and reinforces the sound waves produced by the strings, resulting in a louder and more resonant sound.

Answers
If you were looking at a frog's lifecycle, you would find more specialized cells in the adult frog stage (option b).
In a frog's lifecycle, the adult frog stage is where you would find more specialized cells. This stage occurs after the frog has gone through various developmental stages, starting from the beginning ball of cells.
1. The beginning ball of cells: This is the initial stage of a frog's development. It starts with the fertilization of the egg and the formation of a zygote. At this stage, the cells are not yet specialized and are in the process of dividing and multiplying.
2. Developing tadpole: After the beginning ball of cells, the zygote undergoes further development and transforms into a tadpole. The tadpole stage is characterized by the presence of gills and a tail. The cells in this stage are becoming more specialized but are still relatively unspecialized compared to the adult frog stage.
3. Adult frog: The adult frog stage is the final stage of the lifecycle. At this point, the tadpole has undergone metamorphosis and has transformed into a fully developed frog. In this stage, the cells have become highly specialized to perform specific functions necessary for the frog's survival, such as muscle cells, nerve cells, and specialized organs like the heart and lungs.
4. The same amount at all stages: It is not accurate to say that there is the same amount of specialized cells at all stages of the frog's lifecycle. As the frog develops and goes through metamorphosis, the cells differentiate and specialize to fulfill specific roles and functions required for each stage of development. The highest concentration of specialized cells is found in the adult frog stage.

There are several ways that extremophiles can survive in these extreme conditions like: Heat shock proteins, Membrane adaptations, Enzyme adaptations, DNA repair mechanisms and Metabolic flexibility.
Extremophiles are organisms that can survive and thrive in extreme environments that are inhospitable to most other life forms. These environments can include high temperatures, low temperatures, high pressure, low pressure, and other extreme conditions.
Heat shock proteins: Many extremophiles produce special proteins called heat shock proteins that help protect their cells from damage caused by high temperatures.
Membrane adaptations: Extremophiles often have membranes that are adapted to withstand extreme conditions. For example, some thermophilic bacteria have membranes that are rich in saturated fatty acids, which help maintain their structure and function at high temperatures.
Enzyme adaptations: Extremophiles often produce enzymes that are adapted to work at extreme temperatures or pH levels. These enzymes may have different amino acid sequences, and different shapes, compared to enzymes from non-extremophilic organisms.
DNA repair mechanisms: Some extremophiles have specialized DNA repair mechanisms that allow them to repair DNA damage caused by extreme conditions, such as high levels of radiation.
Metabolic flexibility: Extremophiles often have a wide range of metabolic pathways, which allows them to adapt to different nutrient and energy sources in their extreme environments.

Body Surface Area -adapted from the Redlarski’s paper (link)
Body surface area (BSA) plays a key role in several medical fields, including cancer chemother-
apy, transplantology, burn treatment and toxicology. BSA is often a major factor in the
determination of the course of treatment and drug dosage. A series of formulae to simplify
the process have been developed. Because easy-to-identify, yet general, body coefficient re-
sults of those formulae vary considerably, the question arises as to whether the choice of a
particular formula is valid and safe for patients. These empirical formulae are derived by
observing/fitting the experimental data and do not have a rigid model or reason explain-
ing their validity. In this problem, you will build a physics model to create your own BSA
equation other than using an empircal formula.
(a) Use a cylinder of height H and radius r as a approximation of the shape of a human.
Calculate the human’s body surface area(BSA), volume(V), and mass(M) in terms of
r and H. You may assume the density of human is 1000 kg/m3.
(b) Rewrite the surface area in in terms of height and mass.
(c) According to the equation you derived above, what is your body surface area? Is it the
same as the result calculated by using the empirical fomulae: BSA = √M H/C with
BSA in m2, M in kg, H in cm, and C=60 is a constant in this paper? If not, what is the percentage differences?
Note: percentage difference for two values E1 and E2 are |E1−E2|

Answers
a)Using a cylinder of height H and radius r as an approximation of the shape of a human, the surface area, volume, and mass are calculated in terms of r and H as follows:
Surface area (S) of a cylinder is 2πrh + 2πr², where h is the height, and r is the radius of the cylinder. In this case, the height of the cylinder is equivalent to the height of the human body. Hence;S = 2πrH + 2πr²Mass (M) of a cylinder is given by M = ρV, where ρ is the density of the cylinder, and V is the volume. Hence, the mass of a cylinder in terms of its radius and height isM = πr²HρVolume (V) of a cylinder is given by V = πr²H. Hence, the volume of a cylinder in terms of its radius and height isV = πr²H(b)The body surface area (BSA) of a human can be rewritten in terms of the height (H) and mass (M) as follows:
BSA = √(M/H C)We can rewrite it as H = M/ (BSA² C)Thus, H can be expressed as a function of M and BSA asH = M/(BSA² C)(c)If r = 0.15 m and H = 1.70 m, then using the equation, S = 2πrH + 2πr², the body surface area is given as:
S = 2π (0.15)(1.70) + 2π (0.15)² = 1.77 m²Using the empirical formula, BSA = √(MH/C) with M = 60 kg and H = 170 cm, we get BSA = 1.85 m²The percentage difference is given by;|E1 − E2| / (E1 + E2) / 2 × 100%where E1 = 1.77 m² and E2 = 1.85 m²Thus;|1.77 – 1.85| / (1.77 + 1.85) / 2 × 100% = 4.2%(d)Considering the formula BSA = √(MH/C) with fixed H, a graph with BSA on the y-axis and M on the x-axis can be plotted.The trend shows a non-linear increase in BSA as the mass increases.

(a) (b) (c) (d) (e) (f)
Answers
The residual nucleus for each reaction involving a 16O target is as follows:
(a) (7Li, d) --> 19F
(b) (α, p) --> 19F
(c) (3He, 7Li) --> 16O
(d) (6Li, 7Li) --> 19F
(e) (7Li, p) --> 14N
(f) (p, n) --> 15O
For the stable residual nuclei, the options are (c) and (d), where the residual nuclei are 16O and 19F, respectively.
In nuclear reactions, the target nucleus is bombarded with a projectile, resulting in the formation of a residual nucleus and one or more ejected particles. For each reaction involving a 16O target, the residual nucleus can be determined by subtracting the mass number of the ejected particle(s) from the mass number of the target nucleus.
(a) (7Li, d) reaction:
The ejected particle is a deuteron (d), which has a mass number of 2 and a chemical symbol of H. Thus, the residual nucleus has a mass number of 16 + 7 - 2 = 21 and a chemical symbol of F.
(b) (α, p) reaction:
The ejected particle is a proton (p), which has a mass number of 1 and a chemical symbol of H. Thus, the residual nucleus has a mass number of 16 + 4 - 1 = 19 and a chemical symbol of F.
(c) (3He, 7Li) reaction:
The ejected particle is a lithium-7 nucleus (7Li), which has a mass number of 7 and a chemical symbol of Li. Thus, the residual nucleus has a mass number of 16 + 3 - 7 = 12 and a chemical symbol of O. This residual nucleus is stable.
(d) (6Li, 7Li) reaction:
The ejected particle is a lithium-7 nucleus (7Li), which has a mass number of 7 and a chemical symbol of Li. Thus, the residual nucleus has a mass number of 16 + 6 - 7 = 15 and a chemical symbol of F. This residual nucleus is stable.
(e) (7Li, p) reaction:
The ejected particle is a proton (p), which has a mass number of 1 and a chemical symbol of H. Thus, the residual nucleus has a mass number of 16 + 7 - 1 = 22 and a chemical symbol of N.
(f) (p, n) reaction:
The ejected particle is a neutron (n), which has a mass number of 1 and no chemical symbol. Thus, the residual nucleus has a mass number of 16 + 1 - 1 = 16 and a chemical symbol of O. This residual nucleus is stable.

A. osmosis
B. simple diffusion
C. active transport
D. facilitated diffusion
Answers
The type of transport which is most likely taking place by a carrier protein is called the facilitated diffusion.
What is facilitated diffusion?Facilitated diffusion or passive transport involves a substance diffusing down a concentration gradient across a membrane without requiring the cell to expend any energy.
A concentration gradient is simply a region of space where the concentration of a substance changes, and substances will naturally move down gradients, from a higher concentration area to a lower concentration area.
Some molecules, such as carbon dioxide and oxygen, can diffuse directly across the plasma membrane, but others require assistance to cross its hydrophobic core. Molecular diffusion occurs when molecules diffuse across the plasma membrane with the help of membrane proteins such as channels and carriers.
