Answer:

Keratin has two main functions: to adhere cells to each other and to form a protective layer on the outside of the skin. In epithelial cells, keratin proteins inside the cell attach to proteins called desmosomes on the surface. The desmosomes act as anchors, holding the cells together.

Column A Column B a. Astrocyte b. Axon c. Collateral d. Dendrite e. Myelin f. Neurilemma g. Neurofibrils h. Nissl bodies (chroma
xenn [34]

Answer:

1.) neurilemma (option f)

2.) nissil bodies (chromatiophillic substance)

3.) neurofibrilis ( option g)

4.) myelin ( option e)

5.) dendrite ( option d)

6.) collateral ( option c)

7.) astrocytes (option a)

8.) axon ( option b)

9.) Unipolar neuron (option i)

Explanation:

The neurological terms described above are different parts of a nerve cell or neurones. The nerve cells are the basic Structural units of the nervous system. They are highly specialised for transmitting electric impulses. They can also be grouped according to the number of processes they possess, for example, the UNIPOLAR NEURONS( those with one process only). Each neuron, however, is composed of the same basic parts which include:

--> The CELL BODY: they may be angular or oval in shape with a large nucleus and dense granulated cytoplasm. In the cytoplasm, rough Endoplasmic reticulum which contains CHROMATIOPHILLIC SUBSTANCE (nissil bodies) and Golgi apparatus are also seen.Network of threadlike structures known as neurofibrilis are also seen within the cell body and extending into axon.

--> DENDRONS: these are one or more extensions which branches to form many fine dendrites. The DENDRONS carry nerve impulses( action potential) that their dendrites receive to the cell body.

--> AXON: this is a long process which branches at it's free end to end in synaptic knobs. It carries electric impulses away from the cell body. Most times, a substance of Schwann cell known as MYELIN SHEATH which is composed of lipoprotein insulates axons and increases impulse speed.

How does the concentration of salt in water affect the rate of osmosis?
Nata [24]
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.

In the product 6O2, what does the coefficient mean? There are 12 molecules of O2, There are 8 molecules of O2, There are 6 molec
mars1129 [50]
There are 6 molecules of O2.



"O2" is the formula for one molecule oxygen, which has 2 atoms.

The subscript (small) "2" tells you how many atoms are in the molecule.

The coefficient is the big number tells you the number of molecules.

In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).
