Organize the lengths below from shortest to longest.
28 dm ,629,000 mm ,1.2 km, 30,277 cm
To answer this, all values should be converted in the same
unit just like in km
28 dm = 0.0028 km
629,000 mm = 0.629 km
1.2 km
30,277 cm = 0.30277 km
So the order is 28 dm, 30,277 cm , 629,000 mm and 1.2 km
<u>Answer</u>:
The organic chemicals that helps cell membranes to conserve the internal fluids are phospholipids.
<u>Explanation</u>:
Phospholipids are used to form plasma membrane of the cell. Plasma membrane surrounds the cell contents like various cell organelles, nucleus, ribosomes and proteins. A phospholipid molecules is made up if a polar head containing a phosphate group and the two non-polar tails made of long chains of hydrocarbon of fatty acids.
The another name for plasma membrane is phospholipid bilayer. The polar head is hydrophilic that interactes with polar environment while facing outside the bilayer while the non-polar tail is hydrophobic in nature which makes the internal hydrophobic region of cell membrane which faces inside the bilayer.
The correct answer is hormonal glands
Three important characteristics such as a notochord, a dorsal hollow nerve cord, and pharyngeal gill slits, should appear at any stage of their life cycle. These are the characteristics of the chordates. Members of echinoderms share resemblance with chordates in presence of a notochord.
It is an organic substance.
