Answer:
Chemical change
Explanation:
There are types of changes in nature namely: physical change and chemical change. A physical change is a change that does not alter the chemical composition of the substances involved, hence, no new substances are formed. On the other hand, a chemical change changes the chemical composition of the involved substances to form new substances.
Based on the definition of the types of changes below, the equation depicted in this question is a CHEMICAL CHANGE because it involves a rearrangement of the atoms of each element in the reactants to produce new sets of products with a new chemical formula.
C17H17ON3(s) + 2C4H6O3(l) → C21H21O5N(s) + 2C2H4O2(l)
Answer:
The correct answer would be - D. What causes cancer cells to grow uncontrollably?
Explanation:
A Biologist is a person that studies living organisms and the study of living organisms and their process called biology. Biology is a very vast field that involves many branches such as zoology, botany, biochemistry, immunology, biophysics, anatomy, ecology and many more.
So, given all are can be an example of the study biology wanted to do, however, the question most likely studied by a biologist would be What causes cancer cells to grow uncontrollably as it deals with an organism and their biological process.
The process described at locations U and X are Water changes from gas to liquid.
Answer: Option B.
<u>Explanation:</u>
Water cycle is a cyclical process when the water evaporates from the ground and then falls back on the ground in the form of rain or snow. The various stages of this process are water evaporating from lakes, ground, rivers and so on.
Then it goes up in the air, condenses. And from the condensation process, the clouds are formed. When they cool down up in the air, then the water falls back on the ground and precipitates from the cloud in the form of rain or in the form of snow.
