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.
Answer: D.
Explanation: Members of the same species do not have the same number of cells. Think differences in height or weight. They do not have identical traits. Think siblings. They cannot create different species. Two wolves cannot make a coyote.
Temperature, sunlight and water are all examples of the abiotic components of the ecosystem.
The ecosystem is the interaction and dynamic interdependent exchange of the biotic and abiotic factors of the environment. The biotic factors are the life or living organisms that live in the said environment. While the abiotic factors are those for example, soil, water, wind, air, minerals and etc
Spring currents are made when the moon is in the full or new phases, and are stronger currents. Neap currents are made when the moon is in first or third quarter phases, and are weaker currents
