Members of Kingdom Protista
1. are primarily aquatic
2. do not have membrance bound organelles
3. are all ciliated or flagellated
4. reproduce exclusively by asexual means

Asexual reproduction by pear shaped biflagellate zoospores is seen in most:
1. Green algae         
2. Brown algae
3. Red algae             
4. Both 2 and 3

A feature unique to prokaryotes would be:
1. A cell wall not made up of cellulose
2. An extrachromosomal plasmid DNA
3. A cell membrane of peptidoglycan
4. Presence of inclusions

In oocyte of some vertebrates, the stage of meiosis I that can last for months or years would be:
1. Zygotene
2. Pachytene
3. Diplotene
4. Diakinesis

What is true for both symplast and apoplast movement of water in plants?
1. An equal rate of transport
2. Being down a potential gradient
3. Assistance by cytoplasmic streaming 
4. Conduction through interconnected protoplasts

Magnetic moment of K₃[Fe(CN)₅(H₂O)] is
1. 0
2. 4.92
3. 3.87
4. 2.83

A bullet loses $\frac{1}{20}$ of its velocity passing through a plank. The least number of planks required to stop the bullet is (All planks offers same retardation)
(1) 10
(2) 11
(3) 12
(4) 23

A body is projected with a velocity \(u\) with an angle of projection \(\theta.\) The change in velocity after the time \((t)\) from the time of projection will be:

Two masses, \(m\) and \(M\), are connected by a light string passing over a smooth pulley. When mass \(m\) moves up by \(1.4\) m in \(2\) sec, the ratio \(\frac{m}{M}\) ​​​​is:

Potential energy \((U)\) related to coordinates is given by; \(U=3(x+y).\) Work done by the conservative force when the particle is going from \((0,0), (2,3)\) is:
1. \(15\) J
2. \(-15\) J
3. \(12\) J
4. \(10\) J
