Answer: Chromatography is a technique which is used for the separation of components present in a mixture into sub-components.
Explanation:
The solvent or liquid used for the separation of the chromatographic mixture should lie below the spot point where the mixture is loaded in an alumina column. This is done to prevent the air bubbles formations, which can lead to poor sanitation. Also this is done to prevent the mixing of the mixture to be separated with the solvent instead of running with the solvent via capillary action.
the rod that shows the first increase in temperature
Explanation:
The rod that shows the first increase in temperature is that which has the best thermal conductivity. Thermal conductivity is the ability of a substance to conduct heat.
- Most metals have a high thermal conductivity which results from the transfer of heat due to the fixed vibration of their atoms.
- Substances that conducts heat faster will increase in temperature progressively well are good thermal conducts.
- This shows the relative ease with which their component atoms are able to vibrate and transfer heat.

<span>Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5% or 35 parts per thousand. This means that for every 1 liter (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

Answer:
Every single celled organism is able to survive because it carries out metabolic activities.
Metabolic activity is a set of chemical reactions which are needed for an organism to maintain it's life
Explanation:
the various types of metabolic processes keep an organism alive. There are various types of metabolic processes that takes place in the body of living organism.
These are cellular respiration, reproduction, excretion, digestion et cetera. Every living cell has these processes going on in their body to keep them alive.
Living organism need energy to carry out these processes which they get by eating food.
