The answer is B i know this because
superficial anatomy of the circulatory system
functional anatomy of the circulatory system
superficial anatomy of the nervous system
functional anatomy of the nervous system
its not a nervous system part so there goes the last two and superfical means from the outside of the body like skin and hair and the reproductive like testicals and and the ovarys stuff like that thus leaves your answer with the only logical one {functional anatomy of the circularory system}.

Saturn's moon Mimas has an orbital period of 82,800 s at a distance of 1.87x10^8m from Saturn. Using m central m= (4n^2d^3/GT^2) 1 determine Saturn's mass.
Determine Saturn's mass by rearranging Newton's version of Kepler's Third Law.
Answer:
[tex]5.65\times 10^{26} kg[/tex]
Explanation:
From Kepler's third law: Mass of the planet is given by:
[tex] M = \frac{4\pi ^2d^3}{GT^2}[/tex]
where, T is the time period of satellite revolving about the planet at a distance d. G is the gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg²
Given, d = 1.87 × 10⁸ m
T = 82800 s
⇒[tex] M = \frac{4\pi ^2 (1.87\times 10^8)^3}{(6.67\times 10^{-11})(82800)^2}=5.65\times 10^{26} kg[/tex]

Many dogs have ticks and fleas in their fur. Ticks and fleas feed upon the blood of dogs to get nutrients is that competition, parasitism, mutualism or commensalism
parasitism.
Understanding the Relationship Between Dogs, Ticks, and Fleas
The interaction of ticks and fleas feeding on the blood of dogs is an example of parasitism. In this relationship, the ticks and fleas are considered parasites, benefiting by consuming nutrients from the host, which in this case are the dogs. The host, the dogs, are harmed by this interaction because the parasites can cause discomfort and diseases, such as Lyme disease, which is transmitted by deer ticks. Unlike commensalism, where one organism benefits and the other is unaffected, parasitism negatively impacts the host. Moreover, this is different from mutualism, where both species benefit, and competition, where different species compete for the same resource.

What kind of circuit is the one shown below?
Answer:
The given circuit diagram shows parallel circuit.
Explanation:
In this circuit diagram two bulbs are connected in parallel combination because current flows from the battery gets bifurcated at the junction. Thus, two bulbs are connected in parallel combination.
This parallel combinations of bulbs then connected to the battery given in the diagram. So, the combinations of bulbs are connected in parallel combinations with the battery.
Hence, both bulbs and battery are connected in parallel combinations with each other.
The circuit diagram shown in figure is parallel.
Answer:
The given circuit is in
Series circuit is the one in which there is more than one resistor.
Combination circuit is the one in which gates are used to form the circuit.
Open circuit is the one in which there is no battery.
Parallel circuit is one in which current is divided in different paths.
Here, we can see that we have a battery in the circuit that means it is closed circuit.
And Current is divided that means it is parallel combination.
Therefore, Option D is correct that is parallel.
A cube shaped pool is half full of water. if the water is 3 feet deep, what is the volume when the water is all the way to the top?
The volume of the cube-shaped pool when filled to the top is 27 cubic feet, as the cube has a side length of 3 feet.
To determine the volume of a cube-shaped pool when it is filled to the top, given that the water is currently 3 feet deep and at half capacity, we can apply the formula for the volume of a cube: Volume = length times width times height. Since the pool is half full, and given that the height of the water is 3 feet, it means that the length of a side of the cube is also 3 feet, as it is a cube shaped pool.
Therefore, the volume of the pool when full would be:
Volume = 3 feet times 3 feet times 3 feet = 27 cubic feet.
This calculated volume represents the pool's total capacity, assuming it's filled all the way to the top.

How much energy is needed to increase the temperature of 755g of iron from 283k to 403k ?
To find the energy needed to increase the temperature of 755 g of iron from 283 K to 403 K, we use the specific heat capacity of iron (0.449 J/g °C) and the formula q = mcΔT. After converting the temperatures to Celsius, the calculation shows that 40,714 joules of energy is required.
Explanation:The question asks how much energy is required to increase the temperature of a specific mass of iron. The calculation involves using the formula for heat energy, which is q = mcΔT. The specific heat (c) of iron, the mass (m) of the iron object, and the change in temperature (ΔT) are required to find the total amount of energy needed.
To calculate the energy needed to increase the temperature of 755 g of iron from 283 K to 403 K, we use the specific heat capacity of iron, which is given as 0.449 J/g °C in a comparable example. First, we convert the temperatures from Kelvin to Celsius by subtracting 273 from both temperatures. This gives us a starting temperature of 10 °C and an ending temperature of 130 °C. The change in temperature is then 130 °C - 10 °C = 120 °C.
Using the formula q = mcΔT, where
m = 755 g (mass of iron),
c = 0.449 J/g °C (specific heat capacity of iron),
ΔT = 120 °C (change in temperature),
we can calculate the energy required as:
q = (755 g) x (0.449 J/g °C) x (120 °C) = 40,714 J
This means that 40,714 joules of energy is needed to increase the temperature of 755 g of iron from 283 K to 403 K.
An electron is projected vertically upward with a speed of 1.70 ✕ 106 m/s into a uniform magnetic field of 0.320 t that is directed horizontally away from the observer. describe the electron's path in this field when viewed from above.

Final answer:
The path of an electron projected upward into a horizontal magnetic field, when viewed from above, forms a circular motion due to the magnetic force acting as a centripetal force. The electron will circulate clockwise because of its negative charge.
Explanation:
An electron is projected vertically upward with a speed of 1.70 × 106 m/s into a uniform magnetic field of 0.320 T that is directed horizontally away from the observer. When an electron moves through a magnetic field perpendicular to the direction of the field lines, it experiences a magnetic force perpendicular to both the field and its velocity. This force acts as a centripetal force and causes the electron to move in a circular path.
Since the magnetic field is horizontal and the electron is projected upward, the magnetic force will cause the electron to circulate in a plane perpendicular to the magnetic field. When viewed from above, the path of the electron will be a circle.
It's important to note that the direction of the force and thus the direction of the circular motion depends on the fact that the electron has a negative charge. According to the right-hand rule, as the electron is projected upward, the force will be directed to the observer's left, causing the electron to circulate clockwise when viewed from above.

At what point in a trial process can a plea bargain no longer be entered?
A) when the jury considers the verdict
B) before opening statements
C) after the prosecution rests
D) when the defense rests
Answer:
1. Option D) Deciding if the procedure, principles or techniques in question in a forensic case are generally accepted by the relevant scientific community.
2. Option A) thin-layer chromatography
3. Option A) when the jury considers the verdict
Explanation:
1. The Frye Standard is a procedure to determine if the piece of evidence is admissible in a court of law. This is a rigorous test to test how well the evidence can be used against a criminal or prove a case in the court of law. This came after a ruling that an experts advice only was insufficient to prove a case.
2. Thin layer chromatography is used to separate the ink components. This is because the ink is made of different components that have different volatlitities and solublies in the alcohol solution. The inks can be compared by looking at the partitioning coefficient and comparing the two distances traveled by the components.
3. The guilty cannot plead a case when the verdict has been given. At that moment, the case is closed.
The Frye Standard is used in court to determine if the procedure, principles, or techniques in a forensic case are generally accepted by the scientific community. This standard ensures the admissibility of expert testimony.
