Answer: Option (c) is the correct answer.
Explanation:
A positron is denoted as 
, a neutron is denoted as 
, an electron is denoted as 
, and a proton is denoted as 
.
Therefore, when 
will decay into 
this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.
The reaction will be as follows.
Answer:
The answer would be this: an independent research organization test the product and record the results.

Answer:
D. because water and mud behaved in a similar way in the past as they do today
Explanation:
One of the fundamental theories in the field of earth science is the theory of uniformitarianism.
Uniformitarianism was proposed by James Hutton in the 18th century in Scotland. The theory states that "geologic processes occurring today have occurred in times past and that the present is the key to past".
The simple meaning of the theory is that, the processes on earth today such as weathering, erosion, e.t.c have also occurred in times past. Those processes still occur today and an understanding of such events today will help us have a better insight into the past.
Therefore, ripple marks just as they form today from action of mud and water would be formed in a similar way in the past.
Answer:
The correct answer is d.hydrogen peroxide H₂O₂H₂O₂
Explanation:
Substances can be found in nature in different <em>aggregation states. </em>
Agreggation states can be liquid, gas or solid.
The problem asks about which substance can be found in room temperature as <em>liquid.</em> Each subtances has different physical and chemical properties that determines in which state you can find them at room temperature.
Hydrogen peroxide is the only substance listed that is in liquid state at room temperature, all other substances are in gas state at room temperature.
