Answer:
the total surface area of a human lung IS 70 TO 75 square meters
Explanation:
Estimates of the total surface area of lungs vary from 50 to 75 square metres (540 to 810 sq ft); although this is often quoted in textbooks and the media being "the size of a tennis court"
Answer: hopefully this helps? :)
Explanation:The base pairs are stabilized by hydrogen bonds; adenine and thymine form two hydrogen bonds between them, whereas cytosine and guanine form three hydrogen bonds between them. Figure 7. Hydrogen bonds form between complementary nitrogenous bases on the interior of DNA
RNA, touches nearly everything in a cell. RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments. RNA is usually catalyzed by an enzyme. RNA polymerase using DNA as a template, a process known as transcription. The enzyme then progresses along the template strand.
Answer: Lysosome
Explanation:
The lysosome is an organelle found in cells of eukaryotes.
Its functions include:
I) It contains several hydrolytic enzymes such as
- glycosidases that break down complex sugars (polysaccharides),
- proteases that break down proteins,
- and sulfatases that hydrolyze sulphur-containing compounds,
- other enzymes for lipids and Nucleic acids
II) it also digest worn out organelles, and engulfed viruses and bacteria.
III) and helps to remove wastes from the cell.
