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:
550 milliliters of water is needed.
Explanation:
the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
Explanation:
Irreducible complexity (IC) involves the idea that certain biological systems cannot evolve by successive small modifications to pre-existing functional systems through natural selection.
Answer: Selective breeding
Explanation:
Selective breeding or artificial breeding is a process that allows humans to select parents in plants and animals that have desirable traits. Such parents are bred to produce offspring that have desirable traits from both parents. Humans have bred many species of plants and animals to improve the quality of plant and animal yields in terms of crops, milk, meat, eggs, and other derivatives.
