41. Three patches(A, B.and C) of natural pine forest were equal distance apart from eact (Picture the points of a triangle). Two of the patches (A and B) were conmected to each other by a narrow strip of forest. Patch C is not connected to elither A or Which of these data would serve as evidence that this forest corrider was effective in promoring movement of organisms among patches a. Genetic diversity of Western jays within each patch was the same b. Pine nuts tagged in Patch A were subsequently found in Patch B but not P c. Squirrels were captured in Patch B, marked and released in B. Equal numbers of marked squirrels were later captured in Patches A and C d. Rabits were similarly arured atch CMor rabits were recovered in Pach A than in Patch B. e. No deer were found in any of the patches 42.

The water vascular system of echinoderms is used by various species for a. reproduction b. digestion c. movement d. nervous system communications e. nurture of their young 45. Plants were first able to colonize land because of which adaptation(s)? a. secondary growth b. vascular tissues c. waxy cuticle d. mutualism with mycorrhizae e. all of the above 46. The process of photosynthesis greatly changed the ancient physical world by a. adding oxygen to the atmosphere b. removing toxic carbon dioxide from the atmosphere c. adding water vapor to the atmosphere d. reducing carbon dioxide dissolved in the oceans, thus raising the pH e. reducing the amount of organic matter

Explanation / Answer

Hi Answer:

41. Three patches (A, B and C) of natural pine forest were equal distance a part from each other. Two of the patches (A & B) were connected to each other by a narrow strip of forest. Patch C is not connected to either A or B

Answer: Option. B. Pine nuts tagged in Patch A were subsequently found in Patch B but not in Patch C.

Explanation: Because Patch C is totally isolated from patch A & B. There is a movement of organisms from Patch A to B and vice versa which causes the distribution of pine nuts distribution in both patches but in case of patch C the condition is just reverse.

42. In diploid organisms, the benefit added to one's inclusive fitness by rearing an offspring of one’s own is……that added by rearing an offspring of a sister

Answer: Option A. the same as

43. Which of the following is true about pigeon flocking behavior

Answer: Option B& D

Explanation: Pigeon flocks because of their safety or protection. A large group can easily sight the predator as compare to a single bird. Second in group birds found more opportunities to find food.

44. The water vascular system of echinoderms is used by various species for

Answer: Option B. Digestion

45. Plants were first able to colonize land because of which adaptations

Answer: Option E. All the above

Explanation: The plant is able to colonize on land by developing their secondary growth, a vascular system for water and food need. Having waxy cuticle which protects from infection as well as from water loss and for more nitrogen fixation mutualism with mycorrhizae.

46. The process of photosynthesis greatly changed the ancient physical world by

Answer: Option D. Reducing carbon dioxide dissolved in the ocean, thus raising the pH

Explanation: Studies described that in the ancient physical world Oxygen is very less whereas carbon dioxide found in high quantity. As the process of photosynthesis evolved it start reducing the CO2 present in the ocean due to which the pH of the ocean raised and this pH is suitable for the growth of the different microorganism and other plant species which further changes the ancient physical world.
