Answer:
Hay infusion refers to an amalgamation that can be formed by taking samples from different sources like rivers, lakes, ponds, and others. It is one of the best procedures that can elevate the density of the bacteria cell at any specific time interval.
In the given case, even after boiling hay infusion for one hour, growth was observed in the flask after one day. It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.
Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.
Explanation:
To dissolve, solvent particles must come in contact with solvent particles. Particles of hot water are moving much more rapidly than particles of cold water. Hence, in hot water more water particles will come in contact with hot chocolate powder than in cold water, resulting in faster dissolving.
<span>The Milankovitch theory explains the long term climate change and the </span>
Milankovitch cycles describe the effects of changes as a result of climate change. There are three Milankovitch cycles:about Earth's Eccentricity (the shape
of the Earth's orbit around the Sun), Axial tilt (the inclination of the Earth's axis in relation to its plane of orbit around
the Sun) and precession (the Earth's slow wobble as it spins on axis).
According to this, Milankovitch's cycles <span>are changes in earth's rotation and orbit around the sun that may trigger climate variation. (B).</span>
Answer:
because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature.
