Answer:
C
Explanation:
Nuclear fusion is the process by which the Sun produces its energy. It converts mass into energy, which is radiated over most of our solar system. The pressure from the fusion reactions keeps the star from collapsing.
Without the Sun's energy, in the amount we receive, the Earth would likely be entirely frozen and beyond deathly cold. Take Pluto as an example :)
Answer:
Explanation:
There are many characteristics of life, including, <u>cells.</u> A cell is a tiny unit of life that carries out many different processes.
If something is considered living, it must have at least one cell, but it can have more. For example, bacteria is unicellular and living. We (humans) are also living, but made of billions of cells.
Therefore, for something to be considered living, it must be composed of at least one <u>cell. </u>
Answer: 135 grams of sugar.
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
acts as limiting reagent as it limits the formation of product.
According to stoichiometry:
6 mole of reacts to give 1 mole of sugar
Thus 4.5 moles of will react to give= moles of sugar
Mass of
Thus 135 grams of sugar can be created.
The answer is A
he is known as the father of natural selection :D
