Answer:
The mall and parking lot are not built on a solid foundation.
Explanation:
Sandy soil can erode and possible destroy the mall and parking lot will start deteriorating because of the poor choice of trying to save money but in the long run it will cost more to rebuild on a sold foundation.
If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.
<h3>What is a Metric unit?</h3>
A Metric unit may be defined as a technique of measurement in which the basic units are the meter, the second, and the kilogram. These units are interchanged with one another by using several formulas of conversion.
The complete question is as follows:
Alpha wants to change 0.54 kilometers into a smaller metric unit. She will have to:
- multiply
- divide
- add
- subtract
Therefore, If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.
For example, In case, if she wants to convert 0.54 into meters, then she has to multiply it by 1000, that is, 0.54 * 1000 = 540 meters.

Answer:
Explanation:
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader. A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
These molecules are called antigens, and they are present on all viruses and bacteria.
Answer:
B
Explanation:
Answer B is correct:
Because the biologists are continuing to learn more and more about such minute organisms, protozoan systematics – that is, the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a topic of debate and change, still today.
Some of the rather LARGE and unwieldy taxonomic groupings of past years are particularly subject to revision with expansion of and refinement in the knowledge about the members of those – and related – assemblages. Paradoxically, the protozoa themselves are becoming more difficult to define with precision as our information about them and other microbial assemblages increases. Thus, presenting a single satisfactory circumscribed definition for them is not an easy task.
...
Answer A sounds so funny.
Answer C and D are false because Protozoans are usually single-celled and heterotrophic.
