The answer is H. He is mechanically digesting his food.
Heat increases. Smoke is hot, and as long as you have a cooler air Gulf to the burning substances, then the smoke will rise.<span>

<h2>Scurvy </h2>
Explanation:
(a) Collagen is the major structural component of cartilage,bones and tendons
- The basic unit of collagen is tropocollagen and each tropocollagen consists of three coiled left handed polypeptide chains called α chains
- Generally each α chain consists of a repeating tripeptide sequence called: G-X-Y
- Here G represents glycine; X represents proline and Y represents hydroxyproline
- Rigidity of collagen molecule is due to presence of proline and hydroxyproline
- Hydroxylation of proline is catalysed by prolyl hydroxylase enzyme which use ascorbate,α ketoglutarate and oxygen
- α ketoglutarate is oxidatively decarboxylated to form carbon dioxide and succinate
- Sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues includes: tissue levels of ascorbic acid is low; enzyme prolyl hydroxylase is inactive; proline is not hydroxylated; the triple helix is inadequately stabilized; collagen breaks down; defects in tissues that depend on collagen
; tissues that depend on collagen are subject to breakdown and bruising
(b) Sailors are no longer susceptible to scurvy because fresh fruits which are the source of vitamin C source are available now
British sailors called "limeys" to this day,this term reflects the British navy's use of limes
Answer:
The most appropriate answer would be carbon dioxide and cellular respiration.
Yeast is a single-celled eukaryotic organism which is capable of doing anaerobic (fermentation) as well as aerobic respiration.
It uses cellular respiration (whether aerobic or anaerobic) for the production of energy, that is, adenosine triphosphate (ATP).
Cellular respiration refers to the set of chemical reactions which are involved in breaking down sugar or glucose to produce ATP. The carbon dioxide is produced as a byproduct.
Thus, yeast breakdown the sugar present in apple juice to produce ATP and carbon dioxide.
This carbon dioxide is released in the form of bubbles.
