How does a recessive allele “show up” to be seen?
Answer:
Recessive alleles only show their effect if the individual has two copies of the allele.
Explanation:
Dominant and Recessive Alleles If your allele pair is FF or Ff, you will have freckles. The only way you can escape a freckled face is to inherit the recessive gene from each parent, giving you the ff allele pair. In general, recessive alleles show up in your phenotype only if you have two of them.

John's mass is 55kg when he is standing on the edge of a diving
board 24m high. a. Find his mechanical energy.
What is it?
Answer:
E = 12.9 kJ
Explanation:
Given that,
Mass of John, m = 55 kg
It is standing on the edge of a diving board which is at a height of 24 m.
We need to find his mechanical energy. The mechanical energy of John is equal to its potential energy such that,
E = mgh
E = 55 kg × 9.8 m/s² × 24
E = 12936 J
or
E = 12.9 kJ
So, his mechanical energy is equal to 12.9 kJ.

Light is a wave that has similar properties
as radio waves
Christiaan Huygens
Light is a wave made of electric and
magnetic fields.
James Clerk Maxwell
Light is a wave because this property can
explain interference.
Heinrich Hertz
Light is a wave because it bends when it
hits barriers and openings.
Isaac Newton
Light is made of particles because it travels
only in straight paths.
Answer:
1. Heinrich Hertz.
2. James Clerk Maxwell.
3. Thomas Young.
4. Christiaan Huygens.
5. Isaac Newton.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
However, the various definitions of light according to early scientists include the following;
1. Heinrich Hertz: Light is a wave that has similar properties as radio waves. Heinrich Rudolf Hertz was a German physicist born on the 22nd of February, 1857 in Hamburg, Germany. The unit of frequency ("Hertz") of an electromagnetic wave was named after him.
2. James Clerk Maxwell: Light is a wave made of electric and magnetic fields. James Clerk Maxwell was a Scottish physicist born on the 13th of June, 1831 in Edinburgh, United Kingdom. He was famously known for his work in the formulation of the classical theory of electromagnetic radiation.

Two trucks have the same mass. Which truck will have a greater amount of kinetic energy? b. The truck with less mass d. The trucks will have the same kinetic energy c. The truck with greater speed a. The truck with more mass
Answer:
c. The truck with greater speed
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents speed or velocity measured in metres per seconds square.
From the above formula, we can deduce that the kinetic energy of an object is directly proportional to the square of the value of its velocity or speed.
Hence, the truck with greater speed would have a greater amount of kinetic energy.
Answer:
The trucks will have the same kinetic energy.
Explanation:
Both of the trucks have the same mass, so they have the same kinetic energy. Hope this helps!
How does space exploration affect the economy of Florida?
A) Since rockets launched from Florida are paid for by the federal government, there is a positive effect on Florida's economy.
B) Since rockets launched from Florida pull tourists away from Disney World and local beaches, there is a negative effect on Florida's economy.
C) Since rockets launched from Florida must be purchased from companies located outside of Florida, there is a negative effect on Florida's economy.
D) Since rockets launched from Florida require hundreds of scientists and engineers to move to the area, there is a positive effect on Florida's economy.
Answer:

Three dogs scout sparky and dusty are playing with a teddy bear. Scout and sparky are pullung the teddy bear to the left
Answer:
To the left side.
Explanation:
The teddy bear will move towards the left side because more force is applied by scout and sparky than dusty. The reason for this movement of teddy bear to the left is due to more force is applied by the two dogs present at the left side of the teddy bear while on the other hand, one dog is present at the right side of teddy bear which applied less force so that's why we can say that the teddy bear moves to the left side rather than to the right side.
A Normal force of 16N is distributed uniformly on top surface of a cube of edge 6cm. The
pressure on this surface is Rx104Pa. Find the value of R
Answer:
approx. 0.43
Explanation:
Area of the side of the cube is 36 cm or 0.36 m, P= F/A, so R*104=16/0.36, R*104≅44.44, R≅0.43

25. Suppose there is no unbalanced force acting on a moving object. How will
the object's motion continue?
A. The speed of the object will decrease.
B. The speed of the object will increase.
C. The speed of the object will remain the same.
D. The direction of the object's velocity will change.
Answer:
C
Explanation:
Grammar is probably one of the most important components of the sciences besides math.
no unbalanced forces means that there is no force left over that cause an acceleration. All the forces are balanced.
So the Speed will not decrease. Not A.
The speed will not increase. Not B
The direction will not be affected. Not D
The answer is C

How do the nuclei of covalently bonded atoms help keep the bond together?
Neutral particles in the nucleus provide enough mass that the force of gravity holds the atoms together.
Neutral particles in the nucleus can become positive or negative in order to balance the charges.
Positive particles in the nucleus change into negative particles that enter electron shells.
Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.

Answer:
Condensation can also produce water droplets on the outside of soda cans or glasses of cold water. When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form.
