Which of the following provides the best summary of the process of natural
selection?
A. Population sizes increase with every generation.
B. Individuals pass on their best traits to their offspring.
C. Mutations help an individual survive and reproduce.
D. Well-adapted individuals survive and reproduce.
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.

Explanation:
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.

In a science experiment showing the splitting of water into Oxygen and hydrogen, two inverted test tubes of water were placed over the site of the reaction. (see the pic) How can you tell which one was catching the oxygen and which one was catching the hydrogen?
The hydrogen is a positive ion and will be located close to the negative terminal of the battery.
The oxygen is a negative ion which will be located next to the negative terminal of the battery.
There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.
The hydrogen, being a smaller atom, will take up less space than the oxygen. It will push the water down less.
Answer:
There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.
Explanation:
Electrolysis refers to the decomposition of a solution (electrolyte) owing to the passage of direct current through the solution.
Water is decomposed into its constituents; hydrogen and oxygen by electrolysis. However, a battery is connected to drive the process and other electrolytes such as dilute acids are added to improve the conductivity of water.
In the electrolysis of water, two moles of hydrogen gas is produced for each mole of oxygen gas produced. Hence the ratio of hydrogen to oxygen gas produced is 2:1 by volume. This implies that the space occupied by oxygen is half the space occupied by hydrogen. The hydrogen will thus occupy more space, pushing the water much lower than oxygen.

If Earth was with no tilt, would we still have seasons at all? If so, how would they be different?
Answer:
If earth had no tilt, we would have no seasons.
Explanation:
As stated in the answer, if the earth had no tilt we wouldn't have seasons. The earth all around the globe would maintain the same temperature,
And due to the no tilt it would also change our orbit to a bit larger slant, in January when we are at our closest to the sun we WOULD have a mini summer. For the North and South Pole, they would remain cold.
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.

The woman supports a 100 N load with the friction free pulley system shown below. Fill in the spring scale readings that show how much force she must exert.
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.

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.

A tennis ball and a solid steel ball of the same diameter are dropped at the same time. Which ball has the greater amount of force acting on it?
The steel one.
The steel one has more force due to the weight and mass.
An object's mass is a crucial indicator of how much stuff it contains. The gravitational pull of an object is measured by its weight. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
What ball has the greater amount of force acting on it?The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.
Things fall to the earth faster as a result of gravity. Acceleration is a modification of velocity, and velocity is a measurement of the direction and speed of motion. The longer an object is in free fall, the faster gravity makes it tumble toward the ground.
Therefore, solid steel ball have high mass and greater amount of force acting on it.
