The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.
What is cellular respiration?Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.
The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.
The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces carbon- di- oxide and water along with the release of energy.
Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

How long does it take to produce a star?
Answer: From the moment the first gas cloud begins to compress until the star is formed and glows like the Sun, the process of star creation takes around a million years. Planets and other objects circle the central star using the remaining material from the star's formation.
Explanation:
Answer: Before the gas could disengage from the magnetic field and collapse, every ion in the gas would need to locate an electron to neutralize it. This implies that the formation of a star takes more than 10 million years.

Light travels at 3.0 × 108 m/s in a vacuum
(about the same in air) - how many km/h is
this?
We've got m/s, which is value of distance ÷ time
(distance/time)
3 x 10^8 is:
300,000,000m/s
1km = 1000m
1hr = 3600secs
So, divide 300,000,000m by 1000 to get in km & you get:
300,000km
Now divide this value by 3600 seconds to get it in km/hr
300,000km/3600 = 83.33333333
Thus, answer is 83.3km/h
Or
8.33 x 10^1 km/h (in standard form)
(doing 83.3 recurring multipled by 1000 & 3600 gets you back to original answer. So, 83.33333...x1000x3600= 300,000,000)

Select the correct answer from each drop-down menu. thermal energy moves from a to b by . heat transfer will continue until the liquid in b reaches temperature as the liquid in a.
The correct answer from each drop-down menu is thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.
What is a heat conductor?Good thermal conductors have an atomic or molecular arrangement that has the property of transferring heat to nearby atoms or molecules until the entire object is in thermal equilibrium. To understand better, let's take a metal bar as an example, which is a good thermal conductor.
In this case, the thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.

B: Pierre-Simon de Laplace mentioned the idea of black holes in a written work.
C: Karl Schwarzschild correctly analyzed the relationship between the size of a black hole and its mass.
D: John Wheeler concluded that if black holes did exist, light could not escape them.
Answer:
C: Karl Schwarzschild correctly analyzed the relationship between the size of a black hole and its mass.
Explanation:
Karl Schwarzschild correctly analyzed the relationship between the size of a black hole and its mass. The correct option is C.
What is Karl Schwarzschild's theory?A black hole is an area of spacetime in which gravity is so powerful that nothing, not even light or other electromagnetic waves, can escape. According to general relativity theory, a sufficiently compact mass can bend spacetime to generate a black hole.
Karl Schwarzschild, a German physicist, was the first to "find" black holes. In 1915, he proposed a general relativity solution that was applicable to the simple (i.e., nonrotating, uncharged, and boring) example of a perfectly spherical object contained in otherwise empty space.
These suggestions are now known as the Schwarzschild radius and the singularity. Every item is allocated a Schwarzschild radius, which is determined by the object's mass. Gravity's behaviour begins to become strange within this radius.

A net forward force as well as gravitational force pulls the marble downwards whereas frictional force slows it down.
What is a force?A force is an agent which causes a change in the motion or state of an object.
Forces are of two types:
Contact forces andNon-contact forcesAndrew applies force on the marble causing it to move.
When Andrew pokes the marble, he gives it net forward force. As the marble rolls down the ramp, gravitational force pulls it down.
The movement of the marble is slowed down by frictional force from the ramp.
Therefore, a combination of applied force and gravitational force moves the marble forward, while frictional force slows it down.
