Those plants whose genes have been altered by manipulation are known as _______

The first clinical gene therapy was given to a 4-year old girl with:

Progestasert and LNG-20 are the examples of:

Arrange the trophic levels in an order from lowest to highest in a terrestrial food chain:
(A) Wolf
(B) Grass
(C) Cow
(D) Lion
Choose the correct answer from the options given below:

Arrange the following stages of oogenesis in order of their occurrence.
(A) Ovum
(B) Oogonia
(C) Primary oocyte
(D) Secondary oocyte
Choose the correct answer from the options given below :

Increase in population is due to:

Read the following paragraph carefully and answer the given questions. Certain types of leukocytes (WBC) of our body like polymorpho-nuclear leukocytes (PMNL-neutrophils) and monocytes and natural killer (type of lymphocytes) in the blood as well as macrophages in tissues can phagocytose and destroy microbes. For determining the cause of allergy, the patient is exposed to or injected with very small doses of possible allergens, and the reactions studied. The use of drugs like anti-histamine, adrenalin and steroids quickly reduce the symptoms of allergy. Heroin, commonly called smack is chemically diacetylmorphine which is a white, odourless, bitter crystalline compound. This is obtained by acetylation of morphine. Techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging) are very useful to detect cancers of the internal organs. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.
Which of the following technique is not very useful to detect the cancers of internal organs?

The hormone which control the processes of burning of fats, proteins and carbohydrates, with liberation of energy in the body is :

The repetitive use of which of the following logic gate/s separately can be used to prepare an AND gate ?
(A) OR gate
(B) NOT gate
(C) NOR gate
(D) NAND gate
Choose the correct answer from the options given below :

If \(A=\left[\begin{array}{cc}2 & -3 \\ -4 & 7\end{array}\right]\) and \(2 A^{-1}=K I-A\), where \(K\) is a real number and \(I\) is the identity matrix of order 2 , then the value of \(K\) is :

The electric potential at the centre of a square of side \(\sqrt{2} \, m\) having charges \(90 \, μC, - 60 \, μC, 30 \, μC\) and \(- 40 \, μC\) at the four corners of the square is:

Osmotic pressure measurements are less accurate and difficult to carry out. Therefore, this method is not useful for measuring molecular weights. But it is used to find out molecular weights of polymers eg. plastics, proteins and starch having many monomer units. Knowing the value of osmotic pressure of a given solution, molecular weight of the solute can be calculated using Van't Hoff equation.
When osmatic pressure and temperature for two solutions are same, equal volumes of solutions would contain same number of:

Which of the pair(s) are correctly matched?

(B) Solid in liquid	Cell fluids
(C) Solid in Gas	Mist
(D) Gas in liquid	Pumice stone
(E) Liquid in Solid	Butter
