The following are the two statements about conservation of biodiversity:
When an animal or plant is endangered or threatened, and needs urgent measures to save it from extinction, ex situ conservation is the desirable approach
Ex situ conservation is usually seen as the ideal conservation strategy. Of the above statements, which one of the following options is correct?

Which one f the following is related to Ex-situ conservation of threatened animals and plants ?

The following are the two statements about Amazon rainforest: (a) It is called the 'lungs of the planet'. (b) Amazon rainforest has rich biodiversity. Of the above statements, which one of the following options is correct?

Which one of the following is an example of ex-situ conservation?

The following are the two statements regarding carbon dioxide: (a) Carbon dioxide produced during cellular respiration must be eliminated from the body. (b) Carbon dioxide reacts with water to form carbonic acid and thus increases pH. Of the above statements, which one of the following options is correct

Which one of the following is not used for ex situ plant conservation?

Which one of the following is not used for ex.situ plant conservation?

Consider the following four statements (i)-(iv) about certain desert animals such as kangaroo rat. i) They have dark colour and high rate of reproduction and excrete solid urine ii) They do not drink water, breathe at a slow rate to conserve water and have their body covered with thick hairs iii) They feed on dry seeds and do not required drinking water iv)They excrete very concentrated urine and do not use water to regulate body temperature. Out of these four, which two are correct :

It is not possible to measure the atomic radius precisely since the electron cloud surrounding the atom doesnot have sharp boundary. One practical approach to estimate the size of an atom of a non-metallic element is to measure the distance between two atoms when they are bound together by a single bond in a covalent molecule and then dividing by two. For metals we define the term "metallic radius" which is taken as half the internuclear distance separating the metal cores in the metallic crystal. The vander Waal's radius represents the overall size of the atoms which includes its valence shell in a nonbonded situation. It is the half of the distance between two similar atoms in separate molecules in a solid. The atomic radius decreases across a period and increases down the group. Same trends are observed in case of ionic radius. Ionic radius of the species having same number of electrons depends on the number of protons in their nuclei. Which of the following statement is correct?

Which of the following statements regarding biodiversity hot spots are incorrect? i) High endemism ii) High levels of species richness iii) Total number is 34 in the world iv) Five of these occur in India v) High alien species invasions vi) Cover less than 2% of the earth's land area, but if properly conserved, they can reduce extinctions by about 30%
