Which of the following features of plants is not helpful in adapting to desert life?
1 Presence of thick cuticle on the leaf surface
2 Leaves modified into spines
3 Presence of sunken stomata
4 Absence of trichomes on leaf surface
Explanation:
There are some feature are very helpful in adapting to desert life for any plants. (i) Presence of thick cuticle on the leaf surface. (ii) Leaves modified into spines (iii) Presence of sunken stomata. (iv) Presence of trichomes on leaf surface (epidermis). Function of these structures include defense against insects, protection from excessive transpiration and high heat.

The organisms which generate heat energy within body and also retain it are known as:
1 Endothermic
2 Exothermic
3 Photothermic
4 Geothermic
Explanation:
Exp. AEndothermic- The organisms which are able to generate heat energy within the body and also able to retain it are called endothermic animal and this phenomenon is known as endothermy. b) Exothermic- Ectotherm, any so-called cold-blooded animal- that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invested rates. c) Photothermic- Movement of an organism toward or away from a source of light. d) Geothermic relating to the heat in the interior of the earth.

Ear lobes of arctic fox are smaller than that of tropical fox. This is:
1 Jordon's rule
2 Bergman's rule
3 Gloger's rule
4 Allen's rule
Explanation:
: Allen's rule- State that, body forms such as the limbs, ears and other appendages of the animals living in cold climates tend to be shorter than in animals of the same species living in warm climates. (a) Jordon's rule- The most commonly observed relationship is that fin ray. Vertebrate, or scale numbers increase with decreasing temperature. b) Bergmann's rule- State that, species of larger size are found in colder environments, and species of smaller size are found in warmer regions. c) Gloger's rule- That darker birds are found more often in humid environment that in arid ones, especially in the tropics.

Study the following statements regarding adaptations in fresh water habitat I. Amoeba has contractile vacuole II. Glomerular kidneys in fresh water fishes III. Sponges form gemmules IV. Neoceratodus forms gelatinous cocoon Among the above, the correct statements are
1 I, II, III
2 II, III, IV
3 I, II, IV
4 I, III, IV
Explanation:
Amoeba has contractile vacuole which help in osmo-regulation. It helps in expelling excess water in the unicellular organism. - In fresh water fishes the glomerular kidney function is water excretory function. Renal glomerulus concentrated filtered ions and excretes dilute urine. - Gemmule are internal buds found in sponge and are involved in asexual reproduction.

Maintenance of relatively constant internal conditions (steady state) different from the surrounding environment is called
1 Haemostasis
2 Osmoregulation
3 Homeostasis
4 Biogenesis
Explanation:
Homeostasis is any self regulating process by which an organism tends to maintain stability while adjusting to condition that are best for its survival. While homeostasis is the reaction to stop bleeding and allows body to start repairs on the injury. Homeostasis has 3 main components - Receptor, Control center and Effecter. A homeostasis example is internal body temperature.
