Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
B. the breakdown of glucose in the chloroplast
Explanation:
Explanation:
1. Barr body is a drumstick-like structure of dense, coiled chromatin that appears normally in female's buccal cells and neutrophils. It represents the inactive X-chromosome (Females have two X-chromosomes. Only one is active.)
2. Liver cells are somatic, not sex cells and are thus diploid.
Answer:
Passive transport requires energy and moves materials from areas of relatively lower to higher concentration. Passive transport dose not require energy and moves materials from areas of relatively lower to higher concentration
<span>While
unfortunately, this question is incomplete, it relates to processes that occur
in cells. Catabolic processes involve the breaking down of molecules to release
energy. In anabolic processes, this energy is used facilitate a succession of
chemical reactions to build up larger molecules from smaller component molecules.</span>
