Answer:

C: A 3lb box.

Explanation:

If we were taking about something moving on a surface in which case the answer would be C: a 3lb box because it has the smallest mass therefore it would have the smallest friction.

Unless, the question is asking which would fall faster in which case an 18-wheeler will fall a lot faster than the others because it will provide more net force against the air pressure.

It all depends on if the question is asking which would fall faster or if the question was asking which would move the fastest on a surface. I would just say a 3lb box because the question doesn't use the word fall.

Answer:

depends on how big the car is and what force is moving them.

Explanation:

the 3lb box will go slower because it is the lightest. the 10lb box is the 2nd slowest. the car will be smaller than the 18 wheeler on the road. but it has less cargo so it will probably go faster. if you are dropping it, then the 18 wheeler will go faster. but if you are seeing if it will go faster on the ground, the car will because it has less cargo or wheels to weigh it down.

1. During mitosis, the genetic material in a cell is replicated, and then the cell splits into two new cells. The two new cells

DENIUS [597]

<h2>Answer:</h2><h3>Part 1.</h3>

The correct option is the option C which is all cells come from the pre-existing cells.

Explanation:

Mitosis is the cell division in which one cell divides into two identical cells having same number of chromosomes.

So a cell divide into two giving two cells which further divides.

Even a whole organism come from the division of single cell which is made from the combination of an egg and sperm.

The correct option is the option A which is gene.

Explanation:

DNA contains all the information necessary for a whole organism.

A gene is the unit of DNA which describes a single trait.

For example gene of eye color and gene for insulin production.

So the gene is exact answer to this question while proteins and phenotype are less relevant to question.

Graphs are not given in this question but a graph Will be hyperbola type of inversely proportional. The line in graph descends.

Explanation:

If distance square is on x axis and intensity of light on y axis, The line will move from upward to lower direction.

In the graph at initial distance means low square of distance the intensity will be high and as the square distance increases the intensity will become low.

The line on the graph will descends as the distance square on x axis increases.

The correct answer will be option B.

Explanation:

The process of generating sugar from the carbon dioxide and water in the presence of light and green pigment chlorophyll is known as the photosynthesis.
It occurs mostly in leaves off plants.
While respiration is the breakdown of food generating energy.
And digestion is simplification of complex molecules and osmosis is the transport of water across membrane.
Hence photosynthesis is the correct answer.

The correct answer is the option D which is the population of frogs and mice would increase which would cause the population of grasshoppers to decrease.

Explanation:

Snake is the tertiary consumer in a food web and frogs and mice are secondary consumer while grasshopper is the primary consumer.

As the snake is removed from the food web the population of frogs and mice will increase due to the less pray of secondary consumers.

As frog and mice will increased they will eat more grasshopper making decrease in grasshopper population.

The correct answer is the option B which is the volume of block B is more than A.

Explanation:

The rate of sinking depends upon the density of blocks.

As we know both blocks sink at the same rate. Hence both blocks have same density.

Now the mass measured of block B is more than block A.

But their mass to volume ratio is same. So it means block B has more mass with more volume making density equal to block A.

The correct answer is the option B which is the solution is the base.

Explanation:

Litmus papers are indicators that are used to know the pH of a solution.
They change color as the indication of acidic or basic solution.
A red litmus paper turns into blue when the solution is basic.
A blue litmus paper turns red under acidic solution.

<u>In this question the red litmus changes color to blue it means solution would be basic or alkaline.</u>

The correct answer of this question is the option D which is insulin maintain the homeostasis within the body system.

Explanation:

Homeostasis is body's condition in internal equilibrium. It actually maintains the body in internal condition into dynamic equilibrium.

As the concentration of glucose increases the insulin lowers it. And as the glucose level concentration becomes too low then an hormone known as glycogen is release by pancreas which increases the glucose level in blood.

Hence all mechanism of insulin is to maintain the homeostasis in body.

The correct option is A.

Explanation:

A chemical compound is the combination of two or more than two different elements forming a stable compound.
While an element is the combination of 2 or more than 2 same atoms.
Atoms form elements and elements forms the compounds.
For example C6H12O6 is a chemical compound made from 3 types of elements.
While H2 is an elements.

The option B is the correct option. Jupiter has shortest day in given planets.

Explanation:

The time period of a day of a planet depends upon its rotation around its axis.
A planet with shortest time period of rotation around its axis will have shortest day.
The Jupiter has shortest day. Its spinning time around its axis is 9 hr 55 min 29.69 sec.
It is because Jupiter has small axial tilt of only 3.13 degrees.

Consider a person sliding down a water slide at constant velocity. what are the forces acting on the person as they slide? are t

Andru [333]

Explanation :

When a person is sliding with constant velocity, the forces that are acting on him are :

(1) Weight, W = mg where g is acceleration due to gravity.

(2) Friction forces acting opposite to the direction of motion.

(3) Normal force.

The forces acting on the person is balanced because the person is sliding with constant velocity.

From figure it is clear that, friction force is balanced by $w\ sin\theta$ and normal is balanced by $w\ cos\theta$ .

What evidence can you cite to support the claim that the frequency of light does not change upon reflection?

soldier1979 [14.2K]

Answer: The color of an image is equal to the color of the item forming the picture. When you have a take a observe your self in a mirror, the color of your eyes would not alternate. The reality that the color is equal is proof that the frequency of light would not alternate upon reflection.
