All cells are surrounded by a Cell Membrane
Amniocentesis or amniotic fluid test or AFT refers to the prenatal diagnosis of chromosomal abnormalities and fetal infections. It is performed after 16 weeks of pregnancy. The fetal DNA from a small amount of cells from the amniotic fluid of the amniotic sac is sampled for genetic abnormalities by inserting a needle and extracting it. The fluid contains cells that are sloughed off by the fetus. They are separated from the amniotic fluid, grown in a culture and then microscopically examined for genetic and chromosomal abnormalities. The test is a reliable indicator of chromosomal abnormalities such as Down’s syndrome, spina bifida, muscular dystrophy, rh diseasetrisomy 13, trisomy 18, fragile X, Tay-Sachs disease, Hunter's syndrome and other metabolic disorders.
Answer:
C4 plant are capable to deal with photorespiration
Explanation:
C4 are more efficient than the C3 plants because the C4 have a mechanism to deal with the photorespiration. C4 combat photorespiration by fixing the intial carbon dioxide between mesophyll and bundle-sheath cells (in space)and calcin cycle. The light dependent process and the calvin cycle are separate in C4 plants. Also C4 plants can adapt easily to even hot sunny environment
