[a] Why is my skin white and thick and why is there a thick layer of fat underneath?
The white color of penguins camouflages with the snow so that they cannot be easily spotted. Their thick skin and thick layer of fat protect them from cold and keep warm.

(b) How can the plants like cactus and acacia live in deserts with scarce water?
Cacti are acacias that grow in deserts and have been modified to survive there. As a result of its thick cuticles and deep pit-like stomach, the leaf contains less water that is lost through transpiration. As the leaves are like spines, the stems carry out photosynthesis.
(c) What is the inter-relationship between adaptations of organisms and their surroundings?
There is a very important inter relationship between adaptation of organism and their surrounding, since the organism has to be in the environment to maintain its various biological activities, including shelter, food, and climate.
(d) How are organisms classified?
Living things are classified into seven groups: kingdoms, phyla, classes, orders, families, genera, and species. Kingdoms are the most basic classification of living things.
