Biology
2 answers:
grin007 [14]3 years ago

Answer;

The first choice (A) is an unsaturated fatty acid.

Explanation;

-An unsaturated fat is a fat or fatty acid in which there is one or more double bond in the fatty acid chain.

-A fat molecule is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. In this case, the unsaturated fat (A) is polyunsaturated.

Answer:

Of the given attachments, the first attachment is the correct answer.

Explanation:

A fatty acid refers to a lengthened hydrocarbon chain, which comprises a carboxylic group. The two main kinds of fatty acids are unsaturated and saturated fatty acids. An unsaturated fatty acid comprises a double bond within the fatty acid chain. In case, if a fatty acid comprises more than one double bond than it is termed as polyunsaturated fatty acid.  

Thus, of the given attachments, the first attachment comprises the carboxylic acid with a lengthened hydrocarbon chain and double bond in its composition.

Briefly describe how amniocentesis and chorionic villi sampling are used in genetic screening.
bearhunter [10]

Answer:

Amniocentesis is an invasive method that involves the aspiration of 10-20 ml of fetal water through the abdominal wall under ultrasound-guided control. In most cases, the procedure is performed around the 16th week of gestation. The fetal water sample contains fetal cells, mostly cells of fetal skin and the epithelium of the urinary tract.

Chorionic Villus Sampling (CVS) biopsy is performed between weeks 11 and 12 of gestation. During biopsy, with ultrasound guidance, the tissue of the chorionic fossa is aspirated mainly across the abdomen (transabdominal pathway). The biopsy specimen is of fetal origin and belongs to the outer layer of blastocyst cells or the trophoblast (outer layer of the placenta). Very often, the biopsy specimen contains tissue of the decidua (mucous membrane of the uterus) that is of maternal origin, and it is necessary to remove the maternal tissue before any treatment of the sample.

Explanation:

The amniocentesis procedure carries a risk of miscarriage of 0.5-1%.  After aspiration of the fruit of the water, the sample is centrifuged to separate the cells from the amniotic fluid. Separate cells are seeded on a nutrient medium (cell culture) that stimulates cell growth. After about 14 days, the cell culture is further used for various genetic or biochemical analyzes such as karyotyping.

The advantage of chorionic biopsy is the amount of biological material, which is sufficient for the whole a number of different laboratory procedures. Also, a great advantage is the timing of the procedure as it allows diagnosis in the first trimester of pregnancy, but the chorionic biopsy procedure itself carries a risk of miscarriage of 1-2%.
