Joint Firs are the plants in which division can live as long as 1500 to 2000 years.
Answer:
<h3>In the light, you should expect to see the disks in the control solution (water) stay on the bottom, but the disks in the treatment solution (baking soda) should begin to rise as they use the CO2 to undergo photosynthesis and produce oxygen bubbles. The bubbles should cause the disks to float</h3>
Answer: Garbage collection has proven benefits, including fewer memory-related errors and reduced programmer effort. Garbage collection, however, trades space for time. It reclaims memory only when it is invoked: invoking it more frequently reclaims memory quickly, but incurs a significant cost; invoking it less frequently fills memory with dead objects. In contrast, explicit memory management provides prompt low cost reclamation, but at the expense of programmer effort.
Explanation:
Rocks are made up of minerals
Answer:
Explanation:
This is an example of a mixture which can be separated with simple separation techniques based on the physical properties of the mixtures.Magnetism, and filtration and evaporation
Iron is a magnetic material,but salt and sand are not,Therefore,the iron can be separated from the mixture with the use of magnet.
Salt and sand are mixable.But salt is soluble in water,but sand is not.Therefore by adding the sand and salt to water,the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through,while restricting the sand.
The sand would be removed by the filter paper,while solution passes through.
The salt solution and some sand residues is placed in evaporating dish and heated at low temperature. The water from the solution evaporates,leaving the salt behind.
