Answer:
Option C = ice is less dense than liquid water because the molecules in ice are further apart.
Explanation:
When water is cooled below 0°C, ice is formed. In ice form water molecules have more hydrogen bonds. When temperature increases, hydrogen bonds between water molecules breaks and water gets melt.
In liquid form water molecules are get closer to each other as compared to the ice form. This is the unusual behavior of water as compared to the other substances in solid form.
In ice form water molecules are strongly bonded but the distance between the water molecules are more or we can say that their are empty spaces present between water molecules that's why ice is less dense than the liquid water.
Density:
It is define as mass per unit volume.
The less dense substance float on the surface of water while the substance more dense than water or sink in it.
For example:
Take the two equal amount of blocks one is made up of styrofoam and one is made up metal. Put these two blocks in to water. The block made up of metal will sink while the other made up of styrofoam will float on the surface of water because of difference in densities. The styrofoam is less denser than water while metal more denser then water.
Flagella are hairlike parts that push a bacterium through water or other liquids.
Answer:
If it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.
Explanation:
Dysentery is a bacterial infection caused by an unusual strain of E. Coli, a common bacterium in the large intestine. It is a type of gastroenteritis that results in diarrhea with blood.
