Artemia adult's blood circulation in the tail and appendages.
The adult frog now lives on land and has nostrils and lungs to breathe air. It also has front and hind legs to hop around on. This frog can start the life cycle over again by laying eggs and reproducing.
Algae are producers. This means that they make their own energy and food and do not need to eat other organisms to gain energy and live. Algae use the sun, water, and carbon dioxide to go through photosynthesis and make their own energy to grow, bloom, and reproduce.
The anther is a part of the stamen, the male part of a flower. It produces pollen so that bees and other insects can help spread pollen to other flowers.
Daphnia with beating heart, moving eye and antennae - note internal moving structures.
Anterior end of Daphnia showing beating heart - note moving eyes and other body structures.
Artemia adult appendages with gills.
Artemia blood circulation in the head and around the gut.
Feathery-like appendages are in constant motion. Small pinchers at the front of the head distinguish that the organism is a female. Black dots at the top of the head are the eyes.
Artemia adult blood circulation along the gut.
Artemia naplius with contractions in the digestive tube.
Artemia blood has blood cells that circulate in an open circulatory system.
Artemia with coordinated motion of flipper-like appendages.
This organism is microscopic and does not cause disease and can be beneficial as a food source for other aquatic animals. A mm square grid is used to observe the measure of length of this organism.
Artemia nauplii use appendages as oars to propel themselves.
Artemia juvenile swimming motion.
Artemia adult tail.
Arteries and veins are blood vessels and are part of the circulatory system. Arteries take oxygenated blood away from the heart and veins bring blood back to the heart after it has circulated through the body. The circulatory system distributes oxygen to the body and also moves around nutrients.
The brain and spinal cord (along with nerves) make up the nervous system of animals. The nervous system is responsible for the five senses and many body activities such as movement.
When seeds receive enough water and sunlight, they produce a shoot so they can gather more sunlight above the surface of the soil.
