Answer:
Eukaryotic cells arose through endosymbiotic events that gave rise to the energy-producing organelles within the eukaryotic cells such as mitochondria and chloroplasts.
What happens in nuclear fusion reaction is that<span> four hydrogen </span>nuclei combine in a <span>proton-proton </span><span>fusion </span><span>to form one </span>helium atom. In the process of fusing to form the helium atom, some of the mass of the hydrogen atoms is converted into vast amounts of energy, which is released.

Answer: The correct answer to the question is option E
BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.
Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.
Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.
These chemical processes are explained below;
Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.
Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.
The complete question is :
Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.
Which prediction will most likely describe how friction will affect her findings?
Answer:
The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.
Explanation:
The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.
In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :
F' = F - f
Here, F = the force applied
f = force of friction
And f = μ.N (N = reaction force)
Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.
