The Circulatory System is about the Blood and the heart: they deliver oxygen to the rest of the body (except lungs). AFTER they deliver the oxygen they get the waste (Carbon Dioxide) and deliver it to the LUNGs (Respiratory System)
The Respiratory system is about the Lungs, Bronchi, Alveoli, Trachea, etc. They EXCHANGE the carbon dioxide from the blood with oxygen, they do this in the ALVEOLI (a small, grape-like sockets in the lungs).
The Digestive System consist the Esophagus, Stomach, Intestines, Gallbladder, and Anus. They Digest the food, they ABSORB the nutrients from the food we eat and we poop out the UNNECESSARY wastes.
I believe it's because it uses the movement of the water molecules to hold itself up. I may be wrong...
Answer:
Well Plant cells have vacuoles-Animal cells have vacuoles also, however, animal vacuoles are much smaller. Both plant and animal vacuoles serve as storage areas for water, nutrients, and wastes.
So I wouldn't say they are exactly the same but they are the same :l
Snail:
• They have a shell that is adapted to protect them against predators and the elements.
• They are also adapted to hibernate, especially snails that live in areas prone to frost or freezing temperatures, during the winters. Alternatively, snails in dry, arid regions will estivate - a summer version of hibernation - when water is scare or when there are droughts.
• Snails' slime is naturally hygroscopic, meaning that, instead of releasing water, it attracts it. This helps snails stay damp throughout the day and assists in movement, reproduction and breathing.
Crabs:
• Instead of having an internal skeleton they have exoskeletons. This creates an extremely hard exterior making them more susceptible to attacks from predators.
• All crabs have eight regular legs and two specially adapted legs known as chelipeds or claws. They help them to feed and to catch prey.
• All crabs have both a set of antennae and antennules. They see through their eyes, which are located on the end of long eyestalks. The purpose of these eyestalks is to allow them a better field of vision -- they can see in front of themselves, behind themselves and to the sides -- which is an advantage when hunting or looking out for danger.
Answer:
The chicken wing we received was from the left side because we held it up like it was attached to one of our bodies and the tip was like the human fingertips, and the joint was like the human shoulder joint.
