Answer:
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Explanation:
Isopropyl alcohol causes the DNA to precipitate. When DNA is emerged in the solution, when it comes out it will ideally clump together, making it visible. Isopropyl alcohol is a key ingredient when isolating DNA. Ethanol also can be used to achieve this.
A DNA MOLECULE HAS TWO PAIRED STRANDS
Answer:
So basically, when the osmometer is, the solution in the beaker is supposed to be hypotonic and relative to the solution in the dialysis bag. So when that situation occurs, the net movement of water is transferred into the bag. As the water slowly / hastily moves into the bag, the varying level of pressure is generated which forces the water to move up.
In any ecosystem two factors interact together are abiotic factors and biotic factors. Abiotic factors include non-living such as soil, air, water and climatic factors ( temperature, humidity, rainfall or precipitation) whereas, biotic factors includes all the flora (plants) and fauna (animals). These two factors interact through food chains to function an ecosystem.
