What cause the fluid in the osmometer to rise?
sergij07 [2.7K]

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.

bezimeni [28]

Answer:

The formation of magnesium chloride, MgCl2, is another example of ionic bonding. When magnesium reacts with chlorine, a magnesium atom loses two electrons and becomes a positively charged ion, Mg2+. At the same time, two chlorine atoms gain one electron each and become negatively charged chloride ions, Cl−.

Justify your choice by writing a hypothesis to explain how it has stopped Claire from breaking down her food. The hypothesis is
Troyanec [42]

The complete question is attached to the answer.

Answer:

The correct hypothesis would be -  the food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire.

Explanation:

According to the image, we can find that the normal intestine fluid has the same pH as the pH of claire's Intestine fluid which is suitable for the breaking down of the food or protein in particular. It is also found that there is some amount of protein digested which suggests that there is no mutation in the active site.

According to the graph, claire is able to break down or digest the food completely if 1mg proteases enzyme is used so it proves the enzyme is produced less than normal. On the basis of this information, the correct hypothesis would be -

"The food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire."

Susan needs to measure and heat the chemical she wants to use in an experiment with a graduated cylinder.
defon
<span>Liquids have a medium shape and volume. The particles can move or slide past each other due to the small space available for movement. It cannot be compressed further due to the repulsive forces that act between them. The kinetic energy is medium too. These are the reason why liquids must be placed in a container or vessel to contain them. Beakers, Flasks, and graduated cylinders can contain the liquid. They are like glasses except they are shaped to achieve a specific measurement. Rulers cannot contain the liquid.</span>

Orcas are endangered whales. Only about 80 individuals remain off the 1 point
pantera1 [17]

Answer:

This situation is an example of opportunity cost.

Explanation:

Opportunity cost is a term widely used in the economy, but it can be applied to other areas. This term refers to a choice that must be made between two factors. However, choosing one factor promotes the renouncement of opportunities that the other factor would provide.

An example of this can be easily seen in the question above, where in order to increase the availability of food for orcas and decrease the threat of extinction of this animal, it will be necessary to remove the d*ms from the region. However, if the d*ms in the region are removed, it will not be possible to offer low-cost energy to the population, which can negatively influence the local economy.
