Write two complete sentences for each question for a total of four complete sentences. What is the purpose of cellular respiration? How is cellular respiration similar to photosynthesis?
PLEASE HELP ME
Explanation:
The purpose of cellular respiration is the to provide energy for the body of an organism. In this process, food materials are broken down by complex metabolic actions usually with the availability of oxygen. Then, energy is liberated for use by an organism and the waste is expelled.
Cellular respiration and photosynthesis are both similar. In that they are ways by which organisms obtain nutrition. The food for plant is derived by the process of photosynthesis. Also, other organisms use this food for their own nourishment.

the brake fluid? Even worse what would go wrong if the break fluid leaked out of its pipes?
Answer:
If it leaks....
If there is a brake fluid leak and air gets mixed with the fluid in the brake lines, then the fluid will not be able to flow correctly. As a result, when you press your foot down on the brake pedal, it will feel squishy or spongy. In other words, the brake pedal will feel very soft.
If air bubbles get into....
Air is the enemy in a hydraulic system because it reduces pressure and essentially makes the process less effective. When air gets into the brake lines, your brake system suffers. Symptoms that can indicate you have air in your brake lines include the following: Brake pedal feels spongy when you press down

If a 2 kg ball is moving at 6 m/s to the right and then hits a wall and bounces back at - 4 m/s (left), what is the change in momentum (in kg*m/s)?
Answer:
The change in momentum (in kg*m/s) [tex]= 20[/tex]
Explanation:
The change in momentum is equal to
Final Momentum - Initial Momentum
As we know
Momentum is equal to the product of mass and velocity
M = m * v
Thus, change in momentum
[tex]m_2v_2 - m_1v_1[/tex]
here m1 = m2 = 2 Kg
Substituting the given values in above equation we get -
[tex]2 * 6 -( 2 *-4)\\12 + 8 = 20[/tex]kg m/s

Which part of the drum vibrates when it produces sound?
Explanation:
For example, when a drum is struck, the flexible skin (sometimes called a membrane) of the drum vibrates. The compression and expansion of the air on either side of the vibrating membrane produces differences in air pressure. The pressure differences generate a sound wave that propagates outward from the drum surface.
All materials are made up of elements. Which of the following best describes elements? A. Mixtures combine in several different ways to make many kinds of elements. B. Elements are unable to combine in order to make different compounds. Elements combine in several different ways to make many kinds of compounds. > D. Compounds combine in several different ways to make a limited number of elements,
Answer:
a.
Explanation:
Answer:
I am pretty sure it is C!
Explanation:
According to www.open.edu,
Elements are substances that are made from one type of atom.
Compounds are substances made from atoms of different elements joined by chemical bonds.
A mixture is made by simply mixing together elements and compounds.
Atoms are the basic building blocks.
i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!
B is incorrect because elements ARE able to combine to form compounds!
D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.

C. The particles that make up material B are more closely packed together than the particles that make up material A.
D. The sample of material A has greater volume than the sample of material B.
It's A
Answer: B. The particles that make up material B are more closely packed together than apart because that make up material A!!!

A long platform is holding your physics teacher in the air above some hungry alligators. Your physics teacher has a mass of 75 kg and is located 2 m from one end. The 10.0 m platform has a mass of 10.0 kg, and its center of gravity is located 4.0 m from the same end. The platform is being held up by two students, one at either end.
a. What force is required by each student to hold the platform up?
Answer:
See Below.
Explanation:
I can't transpose the diagram onto Brainly. I'll do my best to describe what is going on.
Draw a horizontal line one inch from the each border of the page.To show what each of A and B are supporting, use an up arrow. Label the Ends A and B. B is on the right side.Put the physics teacher about 1.5 inches from B. His force goes down. Label it as 75 * 9.8 NewtonsPut the platform mass about 2.5 inches from BLabel it as 10 * 9.8 NewtonsB is the balance pointNow put in the distances. The lines are horizontalStudent A: 10 metersCenter of mass: 4 meters to BMass of Physics: 2 meters.Now you are ready to develop the equation
Clockwise
There is only 1 force where B is the Balance point that is going clockwise
10 * Force A
The AntiClockwise Moments
Platform: 4*10kg * 9.8 = 392 N m
Physics T: 2 * 75 * 9.8 = 1470 N m
So the Anti Clockwise moments = the clockwise moments.
10 * Force A = 392 NM + 1470NM Divide by 10. Remember that is in meters
Force A = 1862 N M / 10 10 M = 186 N
Does that make some sort of sense? It should Student A is the furthest distance from where all the action is at B. Therefore he is carrying the lightest weight.
Now what is the total force?
(75 + 10 ) * 9.8 = 85 * 9.8 = 833
This is one of those strange things that won't make sense until it does. Read the next sentence carefully. B is carrying most of the weight. Remember Newtons measure weight.
Support of A = 186 N
Support of B = x
Total of A+B = 933
186 + x = 833
x = 933 - 186
x = 647
So the forces are
A supports 186
B supports 647

When forces of 5 N and 7 N respectively act on an object. When will the resultant of the two vectors be at a maxium
Answer:
F = 12 N
Explanation:
Given that,
Force of 5 N and 7 N respectively act on an object.
We need to find the resultant of the two vectors be at a maximum.
Force will be maximum when two forces acts in same direction. It means we can simply add them i.e.
F = 5 N + 7 N
F = 12 N
Hence, the resultant force is 12N.

Which landform is most likely formed from the destructive and constructive processes from wind forces?
A. Canyon
B.dunes
C. Mountain
D. Valley
Answer:
B.dunes
Explanation:
sand dunes are created by wind
The landform which is formed from the destructive and constructive processes of wind forces is dunes. Hence, option B is correct.
What is a landform?An anthropogenic or natural land feature on the solid surface of the Earth or another planetary body is referred to as a landform. A given terrain is made up of several landforms, and topography refers to how these landforms are arranged in the surrounding area. In addition to shoreline characteristics like bays, peninsulas, and seas, landforms also include hills, mountains, canyons, and valleys. Submerged structures like volcanoes, mid-ocean ridges, and major ocean basins are also considered to be landforms.
Physical characteristics of landforms, such as height, slope, orientation, stratification, rock exposure, and soil type, are used to classify them. Intuitive elements like berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and many more structural and size-scale elements, including different types of inland and marine waterbodies and sub-surface features, are all examples of gross physical features or landforms.
The landform made of wind are :

3 kids are pushing on a cart 2 are pushing north at 50 N each. The 3rd is pushing South at -90 N. The net force is _N?
Answer:
Explanation:
When two forces act in the same direction , they add up and when they act in opposite direction , they subtract .
2 forces each of 50 N act in same direction , so they will add up to give resultant force of 100 N . Now third force acts in opposite direction so 100 N and - 90 N will subtract to give total resultant force .
Resultant force = 100 - ( - 90 ) = 190 N
So net force or resultant force = 190 N .

4. What is the consequence of atoms being a singular closed system?
Atoms of a certain element contain a fixed amount of energy.
Atoms of a certain element can't be altered by outside forces.
Atoms don't interact with each other in any way.
Atoms decompose slowly over time as they lose energy.
Answer:
*Atomos of a certain element contain a fixed amount of energy.
Explanation:
The atoms are said to be closed systems because the number of protons, neutrons and electrons is fixed, so these elements each have an energy given by the electrical interaction with the other elements.
Consequently, the correct answer is: Atomos of a certain element contain a fixed amount of energy.
