1. Adaptation of an animal

The picture represents the adaptation of an animal. An adaptation of an animal is a helpful mutation in an animal, enabling it to survive better in its environment. The picture shows a nocturnal snake, the Northern Copperhead, has slit pupils, a nocturnal adaptation that opens wide to allow more light to enter the snake’s eyes and enhances its night vision. It also has camouflaged skin to blend in with the forest floor, eliminating chances of being noticed, whether it be by a predator or its prey. 

2. Amniotic Egg

This picture represents an amniotic egg. An amniotic egg is a shelled egg containing a fluid-filled sac and yolk to nourish and develop the embryo within. This type of egg is produced by many animals including the chicken that laid this egg pictured.

3. Animal that has a segmented body

        The picture of a lobster represents an animal that has a segmented body. Animals’ segmented bodies are characterized by the division of the body into functional units or repeating sections, such as in worms. Although the lobster is a crustacean, whose body is composed of body segments that are grouped into three integrated units, the head, thorax, and abdomen. From each body segment grows a pair of appendages.

4. Anther and filament of stamen

 This picture shows the anther and filament of the stamen. In a flower, the anther and filament is the reproductive part of the flower where pollen is produced. The anther has the pollen, and is located on top of the supporting filament, the stalk-like structure. This picture shows the red filaments and anthers containing pollen on top of the flower.

5. Autotroph

This picture represents an autotroph. Autotrophs are organisms that are able to produce their own nutrition for sustentation without needing to consume other organisms. This self-made nutrition is formed from simple inorganic substances such as carbon dioxide via photosynthesis and chemosynthesis. Autotrophs include plants, such as the one pictured, and many types of bacteria.

6. Bilateral symmetry

        Butterflies are organisms characterized with bilateral symmetry. Bilateral symmetry is the structural arrangement of an organism in which the body is symmetrical on either side of a central axis. This butterfly is symmetrical when you draw an axis in the middle of its body; the wings and antennae are the same on both sides.

7. Connective Tissue

        This picture represents connective tissue. Connective tissues hold organs in place and bind different parts of the body together, as suggested by the name. The picture of a wrist joint is an accurate representation, because within the joint are connective tissues like tendons and ligaments that hold the arm and hand together.
