The mitochondrial gene tree suggests that hybridization (mitochondrial hybridization) occurred later in the evolutionary time.
What is mitochondrial DNA?The mitochondrial DNA is an independent DNA genome contained inside eukaryotic cells, which is inherited in a matrilineal way.
The differences in the mitochondrial tree and DNA trees are due to the later split process and hybridization over time.
Nuclear DNA undergoes recombination, whereas mitochondrial DNA reflects a matrilineal lineage.

Cooper and his children went into a bakery and where they sell cupcakes for $2.50 each and donuts for $1.50 each. cooper has $40 to spend and must buy a minimum of 18 cupcakes and donuts altogether. if cooper decided to buy 7 cupcakes, determine the maximum number of donuts that he could buy. if there are no possible solutions, submit an empty answer.
Answer: He can buy a maximum of 15 donuts
Explanation: If he bought 7 cupcakes costin $2.50 each then you would multiply 2.50 by 7 which would give you $17.50
then you subtract 17.50 from 40 which gives $22.50 left to use for donuts
then you know you need to have a minimum 18 cupcakes and donuts together so we multiply 1.50 x 11 for the remaining 11 donuts you need and that leaves you with six dollars then if you multiply 1.50 x 4 it gives you the remaining 6 dollars you need so the max number of donuts you may buy is 15

How did otto i gain support from many church bishops?
The way that Otto I gained support from many church bishops is; By using the power of lay investiture.
What is Lay Investiture?Lay Investiture is defined as the system or process whereby the religious leaders are elected and given appointment by the rulers or monarchs of secular states or kingdoms.
Otto I was the ruler of Germany and the Roman empire after the death of his father Henry I. Thus, he took responsibility for installation of the leadership of the local church.
Due to the fact that the installation was supposed to be the rights and duty of the church in appointing the local leaders, Otto's act led to an increase in his loyal followers and this practice of investiture gained a large number of support from many Bishops.

550-nm light passes through a diffraction grating with 3000 lines per centimeter. the screen is 115 cm away from the grating. at what angle, measured in degrees, is the 2nd-order bright fringe located?
The angle measured in degrees at which the 2nd-order bright fringe located is located is; 58.78°
What is the angle of the diffraction grating?Formula for diffraction grating is; dsinθ = mλ
where;
d = grating spacing = 1/(3000 lines per cm) = 1/3 × 10⁻⁵ m
m = order of fringe
λ = wavelength of light = 550 nm = 550 × 10⁻⁹ m.
Now, tanθ = x/D
where;
x = distance of nth order fringe from central maximum.
D = distance of screen from grating = 115 cm = 1.15 m
Now sinθ = d/mλ
θ is small and so we can approximate as sinθ ≅ tanθ
Thus;
d/mλ = x/D
for a second order bright fringe, m = 2.
d/2λ = x/D
x = dD/2λ
For a dark fringe, we have
d/(m + 1/2)λ = x'/D
where;
x' is the distance of the fringe from the central maximum.
For a second-order dark fringe, m = 2. Thus;
d/(2 + 1/2)λ = x'/D
d/(5/2)λ = x'/D
2d/5λ = x'/D
x' = 2dD/5λ
So, the distance between the 2nd order bright fringe and the 2nd dark fringe is; x" = dD/2λ - 2dD/5λ
x" = dD/10λ
Plugging in the values of the variables, we have;
x" = 1/3 × 10⁻⁵ m × 1.15 m/(10 × 550 × 10⁻⁹ m)
x" = 1.15/165 × 10² m
x" = 0.697 m
x'' = 69.7 cm
Thus;
tan θ = x/D = 115/69.7
θ = tan⁻¹(115/69.7)
θ = 58.78°

Atlas corp. is considering two mutually exclusive projects. both require an initial investment of $10,000 at t = 0. project s has an expected life of 2 years with after-tax cash inflows of $6,000 and $8,000 at the end of years 1 and 2, respectively. project l has an expected life of 4 years with after-tax cash inflows of $4,373 at the end of each of the next 4 years. each project has a wacc of 9.25%, and project s can be repeated with no changes in its cash flows. the controller prefers project s, but the cfo prefers project l. how much value will the firm gain or lose if project l is selected over project s, i.e., what is the value of npvl - npvs?
Based on the after-tax cashflows of each project, the value that the firm will gain if Project L is selected over Project S is $56.50.
What are the net present values of Project L and Project S?Project L net present value:
= Present value of inflows - Outflows
= 4,373/1.10925 + 4,373/1.10925² + 4,373/1.10925 ³ + 4,373/1.10925 ⁴ - 10,000
= 14,089.90 - 10,000
= $4,089.90
Project S net present value:
Because project s can be repeated after it is done, the net present value will be:
= (6,000/1.0925 + 8,000/1.0925² - 10,000) + ((6,000/1.0925 + 8,000/1.0925² - 10,000) / 1.0925²)
= $4,033.40

After the torque has been applied for 0.3 s, what are the magnitude and direction of the angular momentum about the center of the disk?
The magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.
Angular acceleration of the diskThe angular acceleration of the disk is determined by applying the principle of conservation of angular momentum as shown below;
Fr = Iα
α = Fr/I
Where;
I is the moment of inertia of the solid diskI = ¹/₂MR²
I = ¹/₂ x (0.5) x (0.08)²
I = 1.6 x 10⁻³ kgm²
[tex]\alpha = \frac{14 \times 0.22}{1.6\times 10^{-3}}\\\\\alpha = 1,925 \ rad/s^2[/tex]
Final angular velocity of the diskωf = ωi + αt
ωf = 45 + (1925 x 0.3)
ωf = 622.5 rad/s
Angular momentumL = Iω
L = (1.6 x 10⁻³) x (622.5)
L = 0.996 kgm²/s
Thus, the magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.
The complete question is below:
A uniform solid disk with radius 8 cm has mass 0.5 kg (moment of inertia I = (1/2)MR²). A constant force 14 N is applied as shown. At the instant shown, the amount of string that has wound off the disk is d = 22 cm, and the angular velocity of the disk is 45 radians/s into the page.

Answer: A
Explanation: P(3 successes)
The probability of getting a vowel on exactly 3 of the spins when the spinner is spin 5 number of times is 0.1646.
What is binomial probabilities?The binomial probabilities is the experimental probability in which the total number of output values is 2, therefore it is known as binomial probabilities.
The number of independence variable in case of binomial experiments is fixed. Both the two output has the 1/2 chances to occur.
It can be given by the function,
[tex]P(X)=\left(^nC_x\right)p^x(1-p)^{n-x}[/tex]
Here, (n) is the number of trial (x) is a number of successes desired and (p) is the probability of success in one trial.
The spinner has 3 sections, let A,B and C, in which A one is vowel. Hence, the probability of getting vowel in one spin is,
[tex]p=\dfrac{1}{3}\\p=0.333[/tex]
It spins the spinner 5 times. Thus,
[tex]n=5[/tex]
The probability of of getting a vowel on exactly 3 of the spins is,
[tex]P(X=3)=\left(^5C_3\right)0.333^3(1-0.333)^{5-3}\\P(X=3)=0.1646[/tex]

Answer:
The most memorable visual aid I have seen used was when a psychology professor used graphic descriptions (through historically important paintings) to illustrate abstract concepts, such as love, madness, and despair.
The representations used in the presentation stuck in my mind because of the visual impact that correlated with my personal experiences, making them vivid and memorable in my mind.
The points illustrated aimed at demonstrating the universality of human passions, and as such, it was an extremely successful presentation.
Finally, what I learned from this experience is that human emotions are not only universal, and as such, they can be represented, but, also, and most importantly, they are emotions that are not abstract concepts, rather, singular and personal experiences to which, paradoxically, everyone is subjected.
