Answer:
-Small molecules are converted into complex organic compounds.
-The reaction requires an input of energy
Explanation:
Reactions in nature can either be energy-requiring or energy-releasing. Reactions that require energy are called ENDERGONIC reactions i.e. energy is needed to start the reaction provees. They are characterized by the INPUT OF ENERGY.
Also, when small molecules are converted into complex organic compounds by combining together in a process called ANABOLISM, energy is needed to put together the molecules to form a much larger complex molecules. Hence, it is a feature of energy-requiring reactions.
Answer:
Production of sucrose in plants from light energy
Explanation:
Answer:
Change in the vascular system.
Explanation:
High blood pressure occurs when the arteries in the human body system become rigid thereby making the blood pressure rise.
The cause for this situation particularly in older people is the changes in the vascular system or circulatory system.
This is said to be vasoconstriction which lowers the flow of blood in the circulatory system, thereby causing high blood pressure
Hence, since Mr. Ackah is a retired teacher, it is believed that he is an old man susceptible to changes in the vascular system or vasoconstriction.
