A 45 g piece of plasticine is placed in water and 30cmcube of water was displaced. Calculate the density of the plasticine in kg

Answer: 1500kg/m^3

Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.

The desert fennec is a small fox that lives in the sahara desert. it has long limbs and long ears. compared to the desert fennec
Vanyuwa [196]
C<span>ompared to the desert fennec, you might expect the arctic fox to have shorter ears.
Given that the desert fennec fox lives in the desert, where it is quite dry and hot, and the arctic fox lives in a place where it is extremely cold, by analogy, if the first fox has long ears, the second one will have shorter ears. Because the locations they live in are quite different, their ears are going to be each other's opposites.

Describe accurately the the basement membrane which underlies epithelial tissues
Nady [450]

Answer:

The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

Explanation:

The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.

It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.

Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.

The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.

Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.
