Answer:
B. Individuals pass on their best traits to their offspring.
Explanation:
because genes are always passed from parents to offspring.
The best summary of the process of natural selection is Individuals pass on their best traits to their offspring. Hence, the correct option is B.
What is the theory of Natural selection?The theory of natural selection gives the mechanism of evolution. It defines the method of different survival and reproduction of individuals due to differences in phenotype.
The theory of natural selection was proposed by Charles Darwin as a way of adaptation and speciation. The variations occur in organisms by random mutations occurring in the genome of individual organisms and this change in mutations may inherit in offspring.
Organisms that are more adapted to the environment are more likely to survive and pass on the genes to future generations. This process cause changes to the generations and diverged over time.
The organisms produce more offspring that are able to survive in the environment. The four factors of natural selection are Variations, Inheritance, Selection, and time.
Thus, the best summary of the process of natural selection is individuals pass on their best traits to their offspring. Hence, the ideal solution is option B.

In a series circuit, electrons only flow along one path. Given this information, which of the following is an advantage of series circuits?
A.
The voltage is the same everywhere in a series circuit.
B.
Less resistance is produced as more devices are added to the circuit.
C.
Series circuits are simpler than parallel circuits.
D.
If one part of the circuit breaks, the other parts will still be able to operate.
Answer:
C. Series circuits are simpler than parallel circuits.
Explanation:
In series circuit, all the components are connected in single path of current flow. If one part of the circuit breaks, the whole thing would break and none of the other parts would work. The voltage is not the same everywhere. It is different across each component. In series circuit, net resistance is more as resistance of all the components connected in series are added up. So, the only advantage of a series circuit is that is simpler than the parallel circuits.
As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which compresses the gases in their blood. What happens to the volume of gas in their blood as the diver rises quickly to the surface?
A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
B.
As a diver rises, the pressure on their body increases which allows the volume of the gas to decrease.
C.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to increase.
D.
As a diver rises, the pressure on their body increases which allows the volume of the gas to increase.
Answer: A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.
Explanation:
The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.
The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.

Suppose that you, with a mass of 48kg, is standing on frictionless roller skates when someone throws you a 2.50kg mass with a velocity of 15m/s and you catch it. What will be your resultant velocity?
Answer:
v = 0.74 m / s
Explanation:
We can solve this exercise using the conservation of the moment
initial instant. Before the crash
p₀ = m v
where m is 2.50 kg and its velocity v₀ = 15 m / s
final moment. After catching the dough
[tex]p_{f}[/tex] = (m + M) v
As the system is made up of the mass and the person, all the forces during the impact are internal, therefore the moment is conserved
p₀ = p_{f}
m v₀ = (m + M) v
v = m / (m + M) v₀
we calculate
v = 2.5 / (2.5 + 48) 15
v = 0.74 m / s
For any energy source including batteries, there will be conduction of electricity if there is a potential
difference
similarity
Answer:
Difference
Explanation:
The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.
If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.
In a “minute to win it” game, cards are placed between cups to stack them. The contestant then pulls the card out in hopes that they will end with a set of stacked cups. Why does this work?
There is no friction between the card and the cup.
Inertia will keep the top cup from moving very far. Gravity will pull one cup on top of another.
The opening of the cup is so much bigger than the bottom, even though the cup moves they will both be stacked together.
Both cups are moved the same amount by the friction between them and the card.
Answer:
There is no friction between the card and the cup.
Explanation:

Answer:
An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration would be
Answer:
12.0 m/s²
Explanation:
Newton's second law:
F = ma
Solving for acceleration:
a = F/m
If force is doubled and mass is tripled:
a' = (2F)/(3m)
a' = ⅔ (F/m)
a' = ⅔ (18.0 m/s²)
a' = 12.0 m/s²
The new value of acceleration of object is 12 m/s².
Given data:
The magnitude of acceleration of object is, [tex]a =18 \;\rm m/s^{2}[/tex].
Let F be initial net force and m be the initial mass. Then as per the problem, the new values of each are,
F' = 2F
m' = 3m
Apply the Newton's Second law, which says that the product of mass and acceleration of object given net force. Then,
F = ma
F = m(18)
F/m = 18 .................................................(1)
Now, for new value of net force,
F' = m'a'
2F = (3m) a'
2F/3m = a'
a' =2/3× (18) (From equation 1)
a' = 12 m/s²
Thus, we can conclude that the new value of acceleration of object is 12 m/s².

if 34.7 g of O2 reacts with iron to form 79.34 g of iron oxide, how much iron was used in the reaction?
A.
19.84 g
B.
44.64 g
C.
104.1 g
D.
114.04 g
Answer: B. 44.64 g
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Mass of reactants = mass of iron + mass of oxygen = mass of iron + 34.7 g
Mass of product = mass of iron oxide = 79.34 g
As Mass of reactants = Mass of product
mass of iron + 34.7 g = 79.34 g
mass of iron = 44.64 g
Thus 44.64 g of iron was used in the reaction
identify the correct order of increasing intermolecular force of attraction for the three most common states of matter.
A) liquid - solid - gas
B) Solid - liquid - gas
C) gas - liquid - solid
D) gas - solid - liquid
The correct order of increasing the intermolecular force of attraction for the three most common states of matter is C) gas - liquid - solid.
What is an intermolecular force in matter?An intermolecular force is a force of attraction or repulsion that exists between molecules or atoms within a substance.
Here,
In the gaseous state, the intermolecular forces are weak, and the molecules are far apart and move freely in all directions. In the liquid state, the intermolecular forces are stronger, and the molecules are closer together, but still able to move past each other. In the solid state, the intermolecular forces are the strongest, and the molecules are tightly packed together in a fixed arrangement, which results in a definite shape and volume.
Therefore, the correct order of increasing the intermolecular force of attraction for the three most common states of matter is gas, liquid, and solid.

Answer:
1. 100N 2. 50N 3. 50N
Explanation:
The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.
What is the spring scale?A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.
The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."
One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.
Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.
