The correct answer is rapids and waterfalls.  

Rapids refers to the segments of streams with extensively vigorous currents, various obstacles, and steps in their streambeds. A waterfall refers to a vertical drop in a stream bed. Both are the locations of vigorous erosion.  

The rapids are generally produced where the resilient bedrock limits a stream to a narrow channel and forces an enhancement in the velocity of water.  

On the other hand, waterfalls are produced where the fast-flowing water negotiates a geologic contact amid the more resilient and less resistant layers of rock, or through a fault, which has analogized distinct kinds of rocks. Or it can be said that waterfalls usually produce at the end of a series of rapids.

What are the role of all four types of lipids: fats, phospholipids, waxes, and steroids.
ycow [4]
Steroids
are complex structure four connected rings of carbon atoms. They are cholesterol which is in all body cells and used to synthesize other steroids:sex hormones, such as estrogen, and testosterone and several hormones from the adrenal glands.

Waxes
are comprised of an ester of a long-chain alcohol and a fatty acid. Many plants have leaves and fruits with wax coatings to help prevent water loss.

Phospholipids
consist of Glycerol portion and fatty acid chains. Only two fatty acids chains; in place of the third is portion that include a phosphate group. THe phosphate portion is soluble in water [hydrophobic] forms the ''head'' of the molecule, while the fatty acids portion is insoluble in water [hydrophobic] and forms a ''tail''.

Fats
to store energy for cellular activities. Carbohydrates fat molecules are composed of carbon, hydrogen and oxygen atoms.

Why is it ineffective to treat viral disease with antibiotics? Why is it ineffective to treat viral disease with antibiotics? Pa
Eddi Din [679]

Answer:

Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes

Explanation:

The specificity of the antibiotics to inhibits some  bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition  antibiotics are designed to  have a significant  destructive  effects on  the mechanisms of biochemical reactions in bacteria and its  physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
