Answer:

Explanation:
Let the allele for dark color be represented by "D" and the allele for light color be represented by "d"
Also D is dominant over d
Similarly, let the allele for obese trait in mice be represented by "O" and the allele for lean trait in mice be represented by "L"
Obese and lean exhibit incomplete dominance
Genotype of true breeding dark and obese mice be DDOO
Genotype of true-breeding lean and light mice is ddLL
Offspring from F1 cross -
DdOL
F2 cross is between DdOL * DdOL
DO DL dO dL
DO DDOO DDOL DdOO DdOL
DL DDOL DDLL DdOL DdLL
dO DdOO DdOL ddOO ddOL
dL DdOL DdLL ddOL ddLL
dark and intermediate between obese and lean offspring genotype –
2 DDOL, 4 DdOL
So total six out of sixteen offspring are dark and intermediate between obese and lean -

<u>Answer:</u>
<h2>
All the waves are pertubations that propagate (transport) energy.</h2><h2>
</h2>
Nevertheless, they have some differences:
1. Light waves are<u> electromagnetic waves</u>, while sound and water waves are <u>mechanical waves</u>, this is the first and principal difference.
2. Electromagnetic waves can<u> propagate in vacuum</u> (they do not need a medium or material), but mechanical waves obligatory need a material to propagate
3. Light waves are always <u>transversal waves</u>, this means <u>the oscillatory movement is in a direction that is perpendicular to the propagation</u>; but mechanical waves may be both: <u>longitudinal waves</u> (the oscillation occurs in the same direction as the propagation) or transversal waves.
4. Electromagnetic waves propagates at a <u>constant velocity</u> (Light velocity) while the velocity of mechanical waves will depend on the type of wave and the <u>density</u> of the medium or material.
5. <u>Mechanical waves</u> are characterized by the regular variation of a single magnitude, while <u>electromagnetic waves</u> are characterized by the variation of two magnitudes: the electric field and the magnetic field
6. <u>Water waves</u> are 2-dimensional waves, while the <u>light and the sound</u> are tridimensional spherical waves
7. Light waves <u>transports energy in the form of </u><u>radiation</u>, while mechanical waves t<u>ransport energy with </u><u>material</u>
Explanation:
Using the formula;
2x = vt
x is the distance up from the ocean floor the submarine is
v is the speed of sound in water
t is the time
Given
t = 2.3s
v = 1490m/s
Required
how high (approx) up from the ocean floor is the submarine x
From the formula;
x = vt/2
x = 1490(2.3)/2
x = 745(2.3)
x = 1,713.5m
Hence the submarine is 1713.5m high up from the ocean floor
Answer:
A. Conservation of energy.
Explanation:
Kirchhoff's loop rule is an example of conservation of energy.
