The placenta is a temporary organ formed during pregnancy that connects the developing fetus to the uterine wall, facilitating nutrient and gas exchange.
The placenta performs several important functions:
List-I (Structures) | List-II (Functions) |
---|---|
(A) Filiform apparatus | (III) Guides pollen tube into the synergid |
(B) Tapetum | (IV) Nourishes the pollen grain |
(C) Exine | (I) Made up of sporopollenin |
(D) Funicle | (II) Attachment of ovule to the placenta |
Find the values of \( x, y, z \) if the matrix \( A \) satisfies the equation \( A^T A = I \), where
\[ A = \begin{bmatrix} 0 & 2y & z \\ x & y & -z \\ x & -y & z \end{bmatrix} \]
(b) Order of the differential equation: $ 5x^3 \frac{d^3y}{dx^3} - 3\left(\frac{dy}{dx}\right)^2 + \left(\frac{d^2y}{dx^2}\right)^4 + y = 0 $
