Amphibians are a group of animals that includes frogs, salamanders, and paper wasps. They have backbones and can breathe through their skin. Unlike reptiles, birds, and mammals, unborn or unhatched amphibians do not grow inside a special protective sac called an amnion.
Anatomy refers to the study of animal organs and tissues, and the characterization of a body or body part based on its structure or organization. Scientists who work in this field are known as anatomists.
Biologists are scientists involved in biological research.
Paper wasps are a type of amphibian without legs. They have a ring-shaped skin fold called an annulus, small eyes covered with skin and sometimes bone, and a pair of tentacles. Most live in the soil, but some spend their entire lives in water.
Evolution is the process by which species change over time, usually through genetic variation and natural selection. It results in new types of organisms that are better suited to their environment. An evolutionary biologist studies the adaptive processes that have led to the diversity of life on Earth.
Fat is a natural oily or greasy substance found in the bodies of plants and animals, mainly deposited as a layer under the skin or around certain organs. Glands are cells, groups of cells, or organs that produce and excrete substances for use elsewhere in the body.
Herpetologists are scientists who study the biology of reptiles and amphibians. Breastfeeding refers to the release of milk by a female mammal after giving birth to nourish her young.
Rubbish refers to a group of young animals born at the same time from the same mother. Mammals are warm-blooded animals characterized by having hair or fur, and females that nurse their young with milk they produce.
Mass indicates how much an object resists acceleration and deceleration, a measure of the material an object is made of.
Ovaries are female reproductive organs that produce eggs and secrete hormones. A Fallopian tube is a tube found in female animals where eggs pass through or develop into young animals.
Rainforests are dense forests rich in biodiversity found in tropical regions with constant rainfall.
Seed refers to a group of similar organisms that can survive and reproduce.
Systems are networks of parts working together to accomplish a function. For example, the circulatory system in the human body or a railway system in a country.
Uterus is another name for the womb, where a fetus grows and matures in preparation for birth.
