Summary Introduction
To determine:
The major theme for the statement given in the book: “Reptilian scales and a waxy coating on many leaves reduce water loss.” and explain how the statement relates to the theme.
Introduction:
Natural selection allows the survival of only those species that acquire the trait which helps in the survival of the species by adaptation of any type such as body parts. The limited

Students have asked these similar questions
1.Explain how vascular tissue allows vascular plants to be larger than nonvascular plants? Make reference to function of vascular tissue and how nonvascular plants obtain water and nutrients.
2.Describe why diffusion alone is an ineffective strategy to move nutrients/exchange gases in larger multicellular organisms.
3.Using your Life Concept Map as a reference, compare and contrast (give an account of similarities and differences between two items, referring to both items throughout the answer) a representative species from two similar kingdoms. A T chart or table might be a good way to organize your answers.
Read the scenario.
A botanist (a biologist who specializes in plant biology) is researching the enormous biodiversity of plants found in the tropical rainforest. As she hikes through the forest, she finds a section of forest that contains several types of flowering plants that are unidentified, meaning they have yet to be named and classified into a scientific group. She observes several different examples of this plant over several acres of forest and notes that the leaves and stems of these plants look very similar. The only part of the plant that varies is the flower. She notes that on the southern side of the forest, the flowers are bright pink and have 18 petals per flower. On the northern side of the forest, the flowers are white and have nine petals per flower.
The botanist wants to determine if the plants she has discovered are of the same species or different species. How would she be able to determine this?
