O A. The twins will not be similar physically but may have similar behaviors.
OB. The twins will not share any similarities.
c. The twins will be identical physically and behaviorally.
D. The twins will be very similar physically but will have some unique behaviors.
The best description of twins with identical DNA is that the twins will be identical physically and behaviorally. Thus, the correct option is C.
What are the identical DNA twins?Identical twins are also called as the monozygotic twins which result from the fertilization of a single egg by a single sperm, or with the fertilized egg which are then splitting into two individual offspring. Identical twins share the same genomes and are also of the same sex.
Identical twins are also called as monozygotic twins, these result from the fertilization of a single egg by a single sperm, with the fertilized egg which then splitting into two identical cells. Identical twins share the same genomes and are always of the same sex.

All music, _______ in the world, is from only ______ notes.
Answer:
All music in the world, is form only two notes and those notes are described below in detailed explanation.
Explanation:
In the chromatic scale, there are basically seven central musical notes, designated A, B, C, D, E, F, and G. They individual express a separate pitch or frequency. For illustration, the "central" A note has a pitch of 450 Hz, and the "common" B note has a pitch of 495 Hz.
Varieties Of Musical Notes You Require To Understand
Semibreve (Whole Note)
Minim (Half Note)
Crotchet (Quarter Note)
All music, listened to in the world, is from only twelve (12) notes.
A music can be defined as the systematic combination of an instrumental sound and human vocals, in order to produce harmonious tunes or sounds.
A note can be defined as a symbol which is used to denote a musical sound with respect to its pitch and duration.
Basically, all the music that are available and listened to in the world are typically produced from only twelve (12) notes.
This ultimately implies that, any musical piece that you may have come across in this world comprises only twelve (12) notes and these include:

What is the size of the force acting on a copper wire with a magnetic flux density of 3.6 x 10 2 T acting at
right angles to the wire of length 19 m and current of 0.043 A? Round your answer to 2 significant
figures.
Answer:
2900 N
Explanation:
We are given;
Magnetic flux density; B = 3.6 × 10² T
Length of wire; L = 19 m
Current; I = 0.043 A
Formula for force in this regards is;
F = BIL
Where;
B is Magnetic flux density
I is current
L is length
Thus;
F = 3.6 × 10² × 0.043 × 19
F = 2941.2
To 2 significant figures gives;
F = 2900 N
The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical
rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.
Answer: Boat P
Explanation:
Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436
The minimum time taken to unwind the rubberband is by boat P.
The highest amount of force to unwind the rubberband is generated by boat P.
Force, Mass and AccelerationThe table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.
Force = Mass [tex]\times[/tex] Acceleration
For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]
For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]
For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]
For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]
Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

The density of iron is 7.97 g/cm. Express it in Sl unit.
Answer:
[tex]d=7970\ kg/m^3[/tex]
Explanation:
Given that,
The density of iron is 7.97 g/cm³.
We need to find the density in SI unit. The SI unit of density is kg/m³.
We know that,
1 kg = 1000 g
1 m = 100 cm
So,
[tex]7.97\ g/cm^3=7.97 \times \dfrac{(\dfrac{1}{1000})\ kg}{(\dfrac{1}{100}^3)\ m^3}\\\\=7970\ kg/m^3[/tex]
So, the density of the iron is [tex]7970\ kg/m^3[/tex].
A 2.0-kilogram mass is moving with a speed of 3.0 m/s. What is the kinetic energy of the mass?
Answer: 9 Joules
Explanation:
Kinetic enegry is one half the mass multiplied by the velocity squared
KE = 1/2mv^2
[tex]KE=1/2(2)(3^2)\\KE=3^2\\KE=9J[/tex]
The kinetic energy of the body is 9J
What is kinetic energy?Kinetic energy is the energy possessed by a body due to its motion.
It is claculated by formula,
K.E = [tex]\frac{1}{2}mv^{2}[/tex]
Here,
The mass of the body = 2.0kg
speed = 3.0m/s
So kinetic energy K.E = [tex]\frac{1}{2}mv^{2}[/tex]
K.E = [tex]\frac{1}{2} (2)3^{2}[/tex] = 9J
So the kinetic energy of the body is 9J

6. Dentists use a soft, clay-like material to make a filling for a cavity. The filling stays soft under the
light of the dentist's lamp, but it hardens when the dentist shines an ultraviolet flashlight on it. Why
does light from the ultraviolet flashlight harden the filling when light from the lamp does not?
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.
What is ultravoilet ray?Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.
Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.
Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,
Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.

A force of 162 N is applied to an object causing it to accelerate at a rate of 3.8 m/s^2. What is its mass?
A. 0.2 kg
B. 616 kg
C. 43 kg
D. 102 kg
Answer:
43 kg
Explanation:
Force (F) = 162 N
acceleration (a) = 3.8 m/s²
mass (m) = ?
We know
F = m * a
162 = m * 3.8
m = 162 / 3.8
m = 43 kg
It's mass is 43 kg.

Which waves have oscillations parallel to their direction of motion
Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.
Explanation:
The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.
What are sound waves?A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.
Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

b) Wavelength cm c) Amplitude
cm
Answer:
see below
Explanation:
a wave means one complete wave which is 1 period
so a) 5 complete waves
wavelength is the shortest distance between any two points in phase
so wavelength = 1 CM
amplitude of a wave is the maximum displacement of a particle from its rest position
so amplitude = 3 CM
