If all your cells were the same, could you still do everything you do now?
Explain.
Answer:
No, you couldn't function the same as you do now.
Explanation:
This is because each cell follows individual tasks, and makes up specific parts of a body. For example, if all of your cells were those of an eye, you would be missing the components of arms, legs, etc.
Answer: No
Explanation: If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.

Answer: hello your question is incomplete below is the missing part
What is Azimuth ?
answer : angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears ( D )
Explanation:
Azimuth is the described as angle of a sound source ( between the North ) and it is measured in a clockwise direction in relation to the observer ( Human ear )
Hence the option that fits in is : angle of a sound source on the horizontal plane relative to a point in the center of the head between the ears

(a). A 10 g meteor hurtling (Moving at greater speed) through the Earth’s atmosphere at 5.0 km s−1. (b). A 65 kg jogger running at 5.0 m s−1.
please help me
Answer:
A
Explanation:
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a __________________ on a heating curve, which occur at the __________________ and ____________________.
Answer:
1. Plateau where the temperature stays constant
2. Melting
3. Boiling points of the substance
Explanation:
The relationship between kinetic energy and temperature is given as follows;
[tex]\overline E = \dfrac{3}{2} \times \dfrac{R}{N_A} \times T[/tex]
Where;
[tex]\overline E[/tex] = The average kinetic energy of the atom
R = The universal gas constant
[tex]N_A[/tex] = Avogadro's number
T = The temperature in Kelvin
Therefore, the kinetic energy increases as the temperature increases, however when the energy is not being converted into kinetic energy, the energy is stored as internal potential energy in the melted or evaporated state of the substance
Therefore, we have;
If energy is going into a system, but not being converted into kinetic energy, it will be converted into potential energy. This will be represented by a 1. plateau where the temperature stays constant on a heating curve, which occur at the 2. melting and 3. boiling points of the substance.

Four 29-ohm resistors are connected in series to an ideal 10-volt battery. What is the equivalent resistance of the circuit?
Answer:
Equivalent resistance of the circuit is 116 ohm.
Explanation:
Finding the equivalent resistance of the circuit. Since, 29 ohm resistors are connected in series, so
→ Equivalent resistance = R_1 + R_2 + R_3 + R_4
→ Equivalent resistance = (29 + 29 + 29 + 29) ohm
→ Equivalent resistance = 116 ohmI. Complete with one of these phrasal verbs: hand back, take off, h

Can you tell from an FBD if an object is moving or not? Explain your response.
Answer:
Yes it is possible to tell if an object is moving or not using a FBD based on Newton's Laws of Motion
Explanation:
A Free Body Diagram is the representation of an object in a diagram that shows (all) the vector of the forces that act on the object
When the sum of all the force vectors acting on the body give a resultant force the object will move in the direction of the force according to Newton's First Law of motion, which states that an object will continue in its rest state or continue its uniform motion on a straight path unless a force acts on the object
The net force, 'F', can be represented according to Newton's Second Law of motion which is F = m·a, where 'a' represents the acceleration (rate of change in velocity) of the object as the object begins to move from rest
Therefore;
From a FBD it is possible to tell if an object is moving or not.
A block of aluminium of density 7900 kg/m3 has a volume of 250 cm. Find the
mass of the block.
Answer:
mass of block=2.7 gm
Explanation:
concept: Density=mass/volume
given:ρ=2700 kg/m^3 and v=250 cm^3 (in cm^3 not in m^3)
=> v= convert cm^3 to m^3
there fore= 1 cm^3=1 cm*1 cm*1 cm
i.e 1 cm^3=1/100*1/00*1/100 m^3 => 1 cm^3=1/1000000 m^3
ρ=m/v
=>mass=ρ*volume
=>mass=2700*1/10^-6
=>mass=2.7*10^-3 kg =>2.7 gm
8. The mediator particle for gravitational force is on
(1 Point)
gluon
vector boson
photon
gravitone
Answer:
Gravitone
Explanation:
In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravity. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity.

What would be the force required to accelerate an object that weighs 35 N up at a rate of .60 m/s^2?
Answer: [tex]2.14\ N[/tex]
Explanation:
Given
Force required to accelerate the object at the rate of [tex]0.6\ m/s^2[/tex]
The weight of the object is [tex]W=35\ N[/tex]
Mass of the object can be identified by dividing the weight by acceleration due to gravity
[tex]\Rightarrow m=\dfrac{W}{g}\\\\\Rightarrow m=\dfrac{35}{9.8}\\\\\Rightarrow m=3.57\ kg[/tex]
[tex]\therefore \text{Force F=}m\times a\\\Rightarrow F=3.57\times 0.6\\\Rightarrow F=2.14\ N[/tex]

Examples of usage of fluid pressure in real life
Answer:
Syringes are used to take blood for blood tests. The pressure of the liquid (blood) forces the liquid to move into the syringe when its plunger is withdrawn. When air is sucked out of a drinking straw, the air pressure inside if decreases and the atmospheric pressure outside forces the liquid to go inside the straw.

A defibrillator is used during a heart attack to restore the heart to its normal beating pattern. A defibrillator passes 18 A of current: through the torso of person in 2.0 ms- (a) How much charge moves during this time
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
[tex]q=It[/tex]
Put all the values,
[tex]q=18\times 0.002\\\\q=0.036\ C[/tex]
So, 0.036 C of charge moves during this time.
Which of the following are states of matter?
A. Liquid
B. Solid
C. Mixture
D. Gas
E. Compound
Answer:
There are four natural states of matter: Solids , liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together, so they don't move much.
Explanation:
sound does not propagate through a vacuum why
Explanation:
Because, there is not atmosphere in vacuum. So, sound does not propagate through a vacuum.
Which of these materials is an insulator?
Answer:
Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook's hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.
If V is the original volume, V' is the new volume, T is the original Kelvin temperature, and T' is the new Kelvin temperature, how is Charles's law expressed mathematically
Answer:
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]
Explanation:
Given the following data;
Original volume = V
New volume = V'
Original temperature = T
New temperature = T'
To write an expression for Charles's law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles law is given by the formula;
[tex] \frac {V}{T} = K[/tex]
[tex] \frac{V}{T} = \frac{V'}{T'}[/tex]

Describe succinctly the relationship between how far a galaxy is from us (its distance), versus how fast it is moving.
Answer:
Distance is directly proportional to the velocity
Explanation:
In 1929, Edwin Hubble's wrote an article that talked about relationship between the distance and recession speed/velocity of galaxies which led to what is known as the Hubble Law. This law states that galaxies are moving away from the earth at velocities proportional to their distances.
Thus is written as;
v = H_o•d
Where;
v is velocity
d is distance
H_o is Hubble's constant rate of cosmic expansion.
He came to this conclusion by generating a graph known as Hubble's classic graph which was a graph of observed velocity vs distance for nearby galaxies.
