What is the major function of the endomembrane system?
Svetllana [295]

Answer:

B. transporting substances in a cell

Explanation:

Endomembrane system is basically a system or organelles and membranes in eukaryotic cells, which is involved in packaging, modifying and transporting the proteins and lipids across the cell.

Many organelles and membranes play role in this system like lysosomes, endoplasmic reticulum, Golgi bodies and nuclear membrane.

Note: Chloroplasts, Mitochondria and peroxisomes are not part of endomembrane system.

You can see figure depicting endomembrane system for better understanding.

kvv77 [185]

Answer:

Explanation:

1. Blood Plasma: this is made up óf water, salts and protein. And it makes up more than half of the total volume of blood

2. Erythrocytes are also known as the red blood cells which makes up some of the solid part of the blood. They are packed with haemoglobin which helps to carry oxygen and they also gives blood the characteristics red color

3. These are also called white blood cells that function in producing antibodies that fights infection. Some types are monocytes, neutrophils, eosinophils etc.

4. Blood platelets: these also make up a part of the solid portion of the blood. They aid in blood clotting preventing blood loss.

Which part of the iceberg displaces water equal in weight to the buoyant force?explain.
ohaa [14]

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:


Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi

So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.

Summary

<span>Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.<span>The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.</span></span>
