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.

Answers

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.

Which term is defined as the force applied to the object divided by the mass of the object?

speed
velocity
mass
acceleration

Answers

Answer:

acceleration

Explanation:

From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.  

Now, the second Newton's law says "F = m . a ", where a is acceleration.

If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:

a = F / m

acceleration = force / mass

How much current must be applied across a 60 Ω light bulb filament in order for it to consume 55 W of power? Unserious answers will be deleted, and reported. (Please show some work)

Answers

Answer: current I = 0.96 Ampere

Explanation:

Given that the

Resistance R = 60 Ω 

Power = 55 W

Power is the product of current and voltage. That is

P = IV ...... (1)

But voltage V = IR. From ohms law.

Substitutes V in equation (1) power is now

P = I^2R

Substitute the above parameters into the formula to get current I

55 = 60 × I^2

Make I^2 the subject of formula

I^2 = 55/60

I^2 = 0.92

I = sqr(0.92)

I = 0.957 A

Therefore, 0.96 A current must be applied.

An airplane moves in straight level flight at constant velocity. What is the
net force acting on it if the mass of the plane is 1000 kg and the frictional
drag of the air is 1800 N? *

Answers

Answer:

Net force = 0

Explanation:

We have, an airplane moves in straight level flight at constant velocity.

Mass of the plane is 1000 kg

The frictional force acting of the air is 1800 N.  

It is required to find the net force acting on it. We know that net force is given by the product of mass and acceleration. But here the airplane moves with constant speed, it means its acceleration is equal to 0 such that net force is equal to 0.

Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn

Answers

Answer:

Producing 300 L of ethanol from potatoes

Explanation:

From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.

1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.

1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material

About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.

In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.

A uniform electric field contains a number of particles. All are experiencing forces in the same direction as the electric field. What can be concluded from this?

All the particles have negative charges.
All the particles have positive charges.
All the particles are charged, but they may be positive or negative.
All the particles must be uncharged.

Answers

Answer: D

All the particles must be uncharged

Explanation:

If all the particles are positively charged, then there will be force of repulsion between them which will give different directions away from each other. The same is applicable if they are all negatively charged.

If the particles are positively and negatively charged, their will be force of attraction between them which will give different directions towards each other.

For all to be experiencing forces in the same direction, We can conclude that

All the particles must be uncharged.

Answer:

This picture represents the electric field diagram between two particles with static charges.

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?

Answers

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.
