Which of the following groups of algae do not have eukaryotic organization?

The number of integral terms in the expansion of $(\sqrt{3}+\sqrt[8]{5})^{256}$ is

Two identical blocks $A$ and $B$,each of mass $m$,are placed on a smooth horizontal surface and are connected by a light spring of length $L$ and force constant $k$. $A$ third identical block $C$ of mass $m$ moves along the line joining $A$ and $B$ with velocity $v$ and collides with block $A$. The maximum compression in the spring is:

$\int_0^2 \frac{2x-2}{2x-x^2} dx$ is equal to

$A$ bimetallic strip consists of metals $X$ and $Y$. It is mounted rigidly at the base as shown in the figure. The metal $X$ has a higher coefficient of linear expansion compared to that of metal $Y$. When the bimetallic strip is placed in a cold bath, what happens?

The solution of $\cos y + (x \sin y - 1) \frac{dy}{dx} = 0$ is
