Biology
Cells are the basic building blocks for all Organisms (every living thing). Cells have a few basic parts that are shared by both plants and animals. All cells have something called the cell membrane. This acts like a boundary, controlling what comes in and goes out. Plants have something slightly
Biology
Our eyes have three cone cells that detect color. These cone cells detect the colors red, green, blue, known as RGB. The reason we can see colors other than red, green, or blue is because every color stimulates more than one cone cell. Their combined response produces a unique signal

Birds do not have lips, they have beaks. Different types of birds have different beaks;hawks have curved and sharp beaks, while ducks have flat and blunt beaks. Woodcocks have beaks that are used to probe the ground. They use their beaks to search for insects inside the dirt and

Eagles are a type of bird of prey that lives on every continent in the world except Antarctica. Male Bald Eagles can grow to be 90 cm (36 inches) long and to have a wingspan of 2 meters. Female Bald Eagles, grow larger than males and may reach 108 cm
Zoology
When you think of a bird, you probably think of an eagle soaring through the air or a seabird wheeling above the ocean; these are all types of flight. Gliding flight is possible only when the forces of lift and drag are adjusted to be equal to the weight of
Zoology
Migration is the movement of birds from one place to another place to find food and nesting locations. There are a few types of migratory birds called Permanent residents, short-distance migrants, medium-distance migrants, and long-distance migrants. Permanent residents are the birds that never move from their location because they have

Birds can communicate with each other through different noises that they make with their Sound Boxes. Birds' do not have voice boxes like us, but have sound boxes. These “sound boxes” are double pronged, allowing the birds to combine two sounds at the same time instead of just one.
Zoology
Birds are special from other animals because they have feathers. They have three types of feathers which are called contour feathers, downy feathers, and filoplumes. Contour feathers cover most of the birds' bodies. These are the feathers that the birds use to fly. Vanes are the silky material of
Zoology
Rainforests are the perfect environment for many animals to thrive because of the abundance of food, water, and warm temperatures that can be found there. Some animals that live in rainforests, such as jaguars and other predators, do not grow so large since these forests are full of trees and
Biology
Pigments are molecules that absorb a certain wavelength of light. Things have different colors because of their pigment combinations. Pigments either absorb or reflect a wavelength, for example, a blue pigment reflects blue and absorbs all the other colors. Different combinations of pigments are used in plants. Chlorophyll is a

In deserts, you can find a multitude of animals that have adapted to the extreme heat and lack of water. Lizards in deserts have thin legs that take very little of the heat from the ground on which they tread. They also are the color of the surrounding rocks, making

In the frozen wilderness of the arctic, animals have adapted to survive the long and harsh winters. Foxes adapt to the winter environment by changing from their usual brown color to that of the surrounding snow. This adaptation allows foxes to be able to sneak up on their prey and
