The genes for green color are dominant over the genes for brown color because all the beetle offspring have a green phenotype. Therefore, option (D) is correct.
What is phenotype?In biology, a phenotype can be described as the observable characteristics of an organism which is the result of the interaction of environmental factors and genes. These traits involve physical appearances and any traits that we can observe.
The phenotype includes its physiological, biochemical, as well as behavioral properties. Genotype is inherited from the parents while the phenotype can be affected by lifestyle and environmental factors. Environmental factors such as nutrition, temperature, humidity, and mental health of the organism.
For example, flamingoes are white in color but turn pink because of the pigments they need from their diet. Therefore, flamingoes portray how they are affected by environmental factors. The phenotype of an organism changes, accordingly to environmental factors.

A key lime pie in a 10.00 in diameter plate is placed upon a rotating tray. Then, the tray is rotated such that the rim of the pie plate moves through a distance of 208 in. Express the angular distance that the pie plate has moved through in revolutions, radians, and degrees. A) Find the angular distance in revolutions, radians and degrees. B)If the pie is cut into 5 equal slices, express the angular size of one slice in radians, as a fraction of .
Answer:
A
The distance in revolutions is [tex]n = 7 \ revolutions[/tex]
The distance in degrees is [tex]\theta =2529 ^ o[/tex]
The distance in radian is [tex]\theta_{radian } = 44.15 \ rad[/tex]
B
[tex]\theta_a = 1.26 \ rad[/tex]
Explanation:
From the question we are told that
The diameter of the pie is [tex]d = 10.00 \ in[/tex]
The distance covered by the rim is [tex]D = 208 \ in[/tex]
The number which the pie is divided into is k = 5
Generally the radius of the pie is mathematically represented as
[tex]r = \frac{d}{2}[/tex]
=> [tex]r = \frac{10}{2}[/tex]
=> [tex]r = 5 \ in[/tex]
Generally the distance covered by the rim is mathematically represented as
[tex]D= 2 \pi r n[/tex]
=> [tex]208 = 2* 3.142 * 5 * n[/tex]
=> [tex]n = 7 \ revolutions[/tex]
Generally converting to degrees
[tex]\theta = n * 360[/tex]
=> [tex]\theta = 7 * 360[/tex]
=> [tex]\theta =2529 ^ o[/tex]
Generally converting to radian
[tex]\theta_{radian } = \frac{\theta * \pi}{180 }[/tex]
=>[tex]\theta_{radian } = \frac{2520 * 3.142 }{180}[/tex]
=>[tex]\theta_{radian } = 44.15 \ rad[/tex]
Generally the angular size of one piece of the pie is
[tex]\theta_a = \frac{2 * \pi }{ k}[/tex]
=> [tex]\theta_a = \frac{2 * 3.142}{ 5}[/tex]
=> [tex]\theta_a = 1.26 \ rad[/tex]
(a) The angular distance is 0.168 revolution, 1.056 radians and 60.5⁰.
(b) The angular size of one slice in radians is 2π radian.
The given parameters;
diameter of the pie, d = 10 mradius of the pie, r = 5 mdistance traveled by the rim, d = 208 in = 5.28 mThe angular distance traveled by the pie plate is calculated as follows;
2πr = 5.28
[tex]2\pi = \frac{5.28}{r} \\\\2 \pi = \frac{5.28}{5} \\\\2\pi = 1.056 \ rad\\\\\frac{1 \ rev}{2\pi \ rad } \times 1.056 \ rad = 0.168 \ rev[/tex]
[tex]1.056 \ rad \times \frac{360^0}{2\pi \ rad} = \ 60.5^0[/tex]
Thus, the angular distance is 0.168 revolution, 1.056 radians and 60.5⁰.
The circumference of the pie is calculated as follows;
C = 2πr
C = 2π x 5
C = 10π
Diving the pie into 5 equal slice;
[tex]Fraction \ of \ one \ part \ in \ radian= \frac{10\pi}{5} = 2\pi\ radian[/tex]
Thus, the angular size of one slice in radians is 2π radian.

What is the value of the initial horizontal velocity?
Answer:
9.8 m/s/s
Explanation:
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its valueis 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, Thehorizontal motion of a projectile is independent of its vertical motion.
Answer:
the horizontal component of the velocity, however, retains its initial value v0x=+115 m/s throughout the entire descent.
Explanation:
since the plane also travels at a constant horizontal velocity of +115 m/s, it remains directly above the falling package.
What is the elastic potential energy of a spring that is compressed a distance of 0.35 m and has a spring constant of 71.8 N/m?
Answer:
P.E = 4.398 Joules.
Explanation:
Given the following data;
Spring constant, k = 71.8N/m
Displacement, x = 0.35m
To find the elastic potential energy;
The elastic potential energy of an object is given by the formula;
[tex] P.E = \frac {1}{2}kx^{2}[/tex]

The mechanical advantage of a lever is 4 . what does it mean?
Answer:
It means...
Explanation:
The mechanical advantage of a machine is 4. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
Answer:
The mechanical advantage of a lever is 4 means that the lever can lift a load which is four times greater than the applied effort.

Which of these determines an objects ability to sink or float in water?
Group of answer choices
1A. Density
B. Volume
C. Mass
D. Weight
Answer:
C. Density
Explanation:
A 60 kg adult and a 30kg child are passengers on a rotor ride at an amusement park as shown in the diagram above. When the rotating hollow cylinder reaches a certain constant speed, v, the floor moves downward. Both passengers stay "pinned" against the wall of the rotor, as shown in the diagram below.
The magnitude of the frictional force between the adult and the wall of the spinning rotor is F. What is the magnitude of the frictional force between the child and the wall of the spinning rotor?
Answer:
fr ’= ½ F
Explanation:
For this exercise we use the translational equilibrium equation, on the axis parallel to the wall
fr - W = 0
fr = W
for the adult man they indicate that the friction force is equal to F
F = M g
we write the equilibrium equation for the child
fr ’= w’
fr ’= m g
in the statement they tell us that the mass of the adult is 2 times the mass of the child
M = 2m
we substitute
fr ’= M / 2 g
fr ’= ½ Mg
we substitute
fr ’= ½ F
therefore the force of friction in the child is half of the friction in the adult

In Alamogordo, New Mexico, falling rocks are a hazard along US Highway 82. If a rock falls from a cliff with 157 N of force,what was the mass of the rock?
Answer:
Mass, m = 16.02kg
Explanation:
Given the following data;
Force, F = 157N
Since it's a free fall, acceleration, a = g = 9.8m/s² (acceleration due to gravity).
To find the mass;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force measured in Newton.m represents the mass of an object measured in kilograms.a represents acceleration measured in meter per seconds square.Making mass (m) the subject of formula, we have;
[tex]Mass (m) = \frac{F}{a}[/tex]
Substituting into the equation;
[tex]Mass (m) = \frac{157}{9.8}[/tex]
Mass, m = 16.02kg
Therefore, the mass of the rock is 16.02kg.

Darius' boat sails into the harbor with a speed of 80m/s. After 20 seconds, Darius' boat has come to a stop at the dock. What is his boat's acceleration?
Answer:
The boat's acceleration is 4 m/s²
Explanation:
This question seeks to test the knowledge of acceleration and how to calculate acceleration when the speed is provided. Hence, the formula for acceleration would be used here.
Acceleration (m/s²) = speed (in m/s) ÷ time (in seconds)
Acceleration = 80 m/s ÷ 20 secs
Acceleration = 4 m/s² or 4 ms⁻²
The boat's acceleration is 4 m/s²
When does the difference between two vectors equal to zero ?
Answer: Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero

C.
Edward Thorndike
D.
Franz Mesmer
Answer:
the answer is B
Explanation:
The development of the theory of reinforcement by B. F. Skinner (Burrhus Frederick Skinner) and his behaviors support for its application to learning contributed to the emergence of the behaviorism and programmed instruction movements. Thus, option B is correct.
What psychologist believed that behaviors by favorable?Small instructional frames, self-pacing, active learner reaction to inserted questions, and fast feedback regarding behaviors the accuracy of a response are all characteristics of programmed instruction.
In essence, individualized education substitutes methodical or pre-programmed materials for the behaviors. Individualized teaching can be delivered by print, computer, or other medium as long as it is founded on the ideas mentioned above.
Therefore, The psychologist who believed that behaviors that are followed by favorable consequences tend to be repeated was B. F. Skinner.
