Answer:
Fungi
Explanation:
The kingdom of Fungi is compromised of eukaryotic organisms that are decomposers, and chitin is used to create their cell walls.
To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.
Answer:
The respiratory system and especially the lungs play an important role in maintaining homeostasis in the body. Gas exchange in the lungs is one of the ways that the respiratory system helps maintain homeostasis. This gaseous exchange of oxygen and carbon dioxide takes place in alveolar sacs present in the lungs.
Answer:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane.
