Answer:
Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". ... So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
The outer planets have a high gravity due to their large size
Answer:
The law of multiple proportions states that when two elements can combine in different ratios to form different compounds, the masses of the element combining with the fixed mass of another element result in whole number ratios. This shows that the law of multiple proportions is followed
Explanation:
The essay will highlight the fact that for every simple machine, there is always friction involved. As per the law of conservation of energy, the energy input to a system is equivalent to the energy output. Some of this output is in the form of friction, which is not useful. As the moving parts in a machine increase, it becomes more complex and more friction is generated between its parts. Therefore, a complex machine ends up being less efficient.
