Answer:
It's less dense. Ice floats because it is about 9% less dense than liquid water.
Explanation:
Answer:
The streak-stab technique reduces oxygen (not completely eliminate it) and allows Streptococcus grow optimally than in a completely anaerobic environment.
Explanation:
Streptolysin is a haemolytic toxin produced by <em>Streptococcus</em>. <em>Streptococcus </em>is a facultative anaerobe, meaning it can grow in the presence or absence of air. However it grows optimally in a micro-anaerobic condition or in 5% CO2.
There are two types of streptolysin produced by <em>Streptococcus </em>–streptolysin O and S. O is oxygen labile (it cannot withstand oxygen) while S is oxygen stable.
O is also produced when the organism is actively growing or near the stationary phase of growth, while S is produced during the stationary phase. To detect the production of streptolysin by the organism on the agar plate, the organism has to be grown at optimum conditions. The streak stab method reduces the level of oxygen, thus providing a condition for the organism to grow maximally.
The hydrosphere makes up all of earths water, and has a secondary sphere called the cryosphere which encompasses all of Earth’s ice. This is important for all living things. Aquatic life lives in water, and land animals drink it to survive.
It is universal because in almost all organisms, the same amino acids are assigned to particular codons, and the code is always read 3 bases at a time, and it is always read in the same direction.
