8.	The feature that makes locomotion in water easy for fish is the? A. scaly body B. slimy body C. streamlined body D. lateral line Show Content Detailed Solution Fish are streamlined because the streamlined shape helps them move through the water with the least amount of resistance/friction There is an explanation video available below.	C
9.	Bird toes suitable for digging have claws that are? A. blunt B. curved C. hooked D. sharp Show Content Detailed Solution Fowls have blunt nails for scratching the ground for: forage dust bath *nest preparation There is an explanation video available below.	A
10.	Which of the following is an example of carnivorous plant? A. hydra B. bladderwort C. yeast D. spirogyra Show Content Detailed Solution Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods.
