The answer is gypsum as 2 is lower than 2.5 and since the other minerals are very hard, it would cause damage to the fingernail since the fingernail's hardness is 2.5.
My best educated guess would be more of earth's freshwater is found underground (aquifers) than in lakes
The water vapor in the relatively warmer, and more moist air condensed, hence fogging your glasses. Warm moist air comes in contact with a colder surface, you get condensation.
Hope this helps!
Answer:
Capsule
Explanation:
In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.
The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.
In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.
Thus, the capsule is correct.
Though technically there are six levels of organization in ecology, there do exist some sources which only identify five levels, namely organism, population, communities, ecosystem, and biome; excluding biosphere from the list.
