Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.
Answer:
D two organisms depend on each other for survival.
Explanation:
Symbiotic relationship is a type of relationship between two organisms in which the both of them gain something positive from each other. A good example is the relationship between the cattle and egret. The egret helps in grooming the cattle and the cattle in return provides food for the egret.

Answer:
allele, changing, increasing
Explanation:
The allele that an organism inherits from its parents influence its phenotype. Phenotypes can also be influenced throughout an organism’s lifetime by changing the expression of particular genes. For example, increasing the expression of an allele will often accentuate that allele’s phenotype.
<em>Allele represents the alternate form of a gene. Hence, the allele inherited determines the phenotype of an organism.</em>
<em>The physical appearance of an organism is also influenced by gene regulation. A gene can be turn on/off as the the case may be and this will affect the phenotype.</em>
<em>Increasing the expression of an allele will accentuate or emphasize the phenotype the allele controls and vice versa.</em>
