Answer:
Commensalism.
Explanation:
Commensalism is a symbiotic relationship that exist between organisms in which one organisms benefit from the relationship and the other neither benefit of is harmed. From the question the algae benefits by getting accommodation and nutrients from the floating plants but the floating plants neither benefit or is harmed.
Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.
Answer:
The oxygen atoms of CO2 originated from glucose and the oxygen atom of H2O is originated from normal oxygen molecule that act as reactant during the break down of glucose by oxidation.
Explanation:
C6H12O6+6O2=6CO2+6H2O+Energy
In the above reaction glucose is being reduced to generate CO2 .As a result the oxygen of CO2 is originated from glucose.
The above also deals with the reduction of oxygen to H2O.From that point of view it can be stated that the oxygen atom of H2O originates from molecular oxygen that act as reactant.
