certain substances are placed in the beaker in given picture if the following items are placed in a water filled beaker then sta
Yuliya22 [10]

Answer:

1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.

2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.

Explanation:

Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.

With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.

Why is it important that human chromosomes have many origins of replication
8_murik_8 [283]

Answer:

Chromosomes contain very large genetic information which would take many hours to replicate with only one origin.

Explanation:

Human cells are eukaryotes, meaning that the genetic information is compressed in chromosomes, that at the same time are contained in the nucleus. As the replication requires all the genetic information to be copied, the length of it would take several hours to complete this task. Therefore, with many origins of replication, this process happens faster and more effectively.
