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.
Meiosis creates 4 different cells they are not copied like mitosis
Answer:
Red blood cells are a type of specialized cell that move <u>oxygen </u>and carbon dioxide throughout the body.
A structure made of two or more tissues working together to achieve a common function is a/an <u>an</u><u> </u><u>organ</u><u> </u>
<u>cellular </u><u>defferentiation</u><u> </u>describes the degree of specialization that a cell is able to undergo.
A/An <u>embroynic</u><u> </u>stem cell can differentiate into all cell types found within an embryo.
In <u>cytoplasm</u> organisms, all cellular activities take place within a single cell.
Answer:
Option C.
Ocean acidification is the main ecological problem due to mariculture.
Explanation:
- Mariculture also known as the aquaculture that stands for the fish farming occupation.
- The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
- Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
- A build up of organic material beneath fish farms impacts the flora and fauna of an area.
- That makes drastic changes on sediment chemistry.
