Question
Microarrays allow for
•a comparison of expression of different genes under different growth conditions.
• the analysis of global gene expression.
•the hybridization of cDNA (converted from mRNA with DNA affixed to a solid-state support.
• all of the above.
Answer:
• all of the above.
Explanation:
Microarray involves the collection and isolation of genetic samples (DNA) from a sample or tissue.
Microarray is composed of a large number of DNA material that is arrange sequentially for easy identification and use.
Microarray is used to compare the expressions of various types of genes that are growing under different conditions. It can also be used for analysis of genes globally.

Explanation:
<span>Root hairs and all active transport mineral ions are used by plants to enable water absorption. The route of the movement of water inside the root would be illustrated through this sequence:Epidermis (outside layer of the roots) --> cortex (ground tissue layer just between the epidermis and the root's vascular tissue) --> endodermis(a layer outside the vascular tissue;responsible for mineral uptake of plants) --> stele( tissues combined inside the cortex) --> xylem (can be primary and secondary, both originates from provascular tissue and vascular cambium,maturing to its inside, respectively) --> phloem (can be primary and secondary too, both originates from provascular tissue and vascular cambium,maturing to its outside, respectively --> cambium(a meristem originating from an apical meristem, gives rise to secondary xylem and secondary phloem. </span>
The correct answers are:
A. People enjoy cruise vacations;
B. People need to cross the ocean;
E. People need to earn a living;
The vessels that are going through the ocean waters are both very useful and damaging in the same time, depending on the perspective. From one side, lot of people use them as a mean of traveling from one side to the other side of the ocean, millions of people enjoy going on vacation on the ocean/sea cruises, and also millions of people are employed and make a living from those vessels. On the other hand, all of the sewage from those millions of people is released into the ocean waters, thus causing pollution of the waters, which effects the marine life and its well-being.
