Amniocentesis is a prenatal diagnostic procedure where a small amount of amniotic fluid surrounding the fetus is extracted for testing. Here's a breakdown of why the best answer is "Determine the sex of the fetus" and further details:
Purpose of Amniocentesis:
Why the other options are less accurate:
Therefore, the most accurate answer is: Determine the sex of the fetus. Although primarily used for detecting genetic and chromosomal abnormalities, amniocentesis also reveals the sex of the fetus.
Amniocentesis is a medical procedure primarily used to:
Determine the sex of the fetus
However, it is important to note that amniocentesis is more commonly performed for other diagnostic purposes, such as detecting genetic abnormalities, chromosomal disorders, and certain birth defects. The determination of fetal sex is just one of the many outcomes that can be derived from this procedure.
Label the following layers around ovum properly.
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
