Answer:
The sequence of a series of events.
Explanation:
Some scientist prefers to use the therm chronometric or calendar instead of the word absolute.
It is the process of attributing to an object or event a date in the past, by doing this the object could be placed in a previously established chronology. It is usually based on physical, chemical, and life properties of the materials of artifacts.
I hope this answer helps you.
Apparently it’s called the ovum
Answer:
c water
Explanation:
water isn't pollutant its just water if it was then we would all be dead most likely. just common sense hope this helps OwO to elaborate some water is polluted but not all water is, but air atmospheric pollutants are more common, just trying to make sense of it lol
Answer:
1)Diffusion
2)yes, because of size difference
Explanation:
1) Biological cells live and grow by the inside and outside movement of molecules and diffusion is a process which takes place when molecules move from higher concentration area to lower concentration area. When cubes of agar alongwith indicator (phenophthalein) is added into vinegar, the hydrogen ions move from vinegar into the agar cubes and change in color appears. This change of color indicates the diffusion of vinegar into agar cubes
2) The diffusion distance differs between the cubes because of different sizes of the cubes. The difference in size results in difference of surface area which can be calculated by the volume of the cube. Larger the cube is, the more time vinegar will take to diffuse into the agar cube.
Answer:
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can exploit these properties. Helium was the first gas used for filling balloons and dirigibles.
