Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules
<span>Mass defect is the difference between predicted and actual experimentally determined mass. The predicted mass of a sample is found by adding the mass of the neutrons and protons (to be accurate, electrons as well) within that sample, and we know what the individual masses of these particles are so multiplication isn't a problem. This mass is usually higher than what is measured experimentally because some of this mass turns to binding energy with the relationship e is roughly equal to m(c)^2.
If you are asking how we possibly add the masses of all those atoms of the Helium and Hydrogen we experiment with, we do it using the formula (number of atoms * number of protons per atom) + (number of atoms * number of neutrons per atom) + (number of atoms * number of electrons per atom). The number of atoms is found using the total mass of the sample alongside some experimental data.</span><span>

1.The thermosphere: is used for orbitting satellites and increases in temperature as altitude increases.
2.Convection currents in the mantle cause the movement of crustal plates.
Use this to help you. So here velocity is not given… so we have to calculate velocity of the car from given data. Car travel 60 km in 35 minutes. Frist of all we have to convert 35 minutes in hours by deviding 35 to 60 hour = 35/60
Next we have to calculate distance in kilometres so distance =velocity ×time.
Velocity =distance / time
Velocity =60/(35/60)
Velocity=3600/35
Distance = velocity ×time
In one hour… it will travel…
Distance =(3600/35) ×1.
By dividing you will get the answer…hope it will
