What material is the exoskeleton of arthropods comprised?
The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc. Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow.
Why does insects exoskeleton limit growth?
Insects have an exoskeleton made of chitin that provides structure and support. This exoskeleton does not grow or stretch, so the insect must molt to shed the old exoskeleton and grow a new, larger one. Limited by the molting process, insects cannot continuously grow like humans with an internal skeletal structure can.
Can crickets become over weight?
No, they jump to much for that (just kidding, anything with an exoskeleton can become overweight, especially insects.)
What bug has the toughest exoskeleton?
The rhinoceros beetles have the toughest and strongest exoskeleton. They are able to carry and move things 850 times their weight.
Insects can never be as big as rats because there cuticle is too big?
There is an upper limit to the size insects and other creatures with an exoskeleton can reach. At a certain size, the exoskeleton will collapse under its own weight. But there were invertebrates as big as or bigger than rats in the past, for example dragonflies with a wingspan of 3 feet or sea scorpions that reached a length of 7 feet (being aquatic helps, since the water will support the exoskeleton).http://en.wikipedia.org/wiki/EurypteridToday, the biggest beetles (Titan and Hercules beetle) are up to 6.5 inches long and that is the size of a small rat. But apparently, that's about as big as they get today.
How do ants pick up things?
They have a strong exoskeleton and can lift 10x it's weight.
How do you converting from atomic percent to weight percent?
How can I convert atomic percent to weight percent for example TiC -45%atomic C convert to weight percentage?
Why do small insects flout in water?
because boyancy lats the insects weight
Does weight-bearing on a fracture mean percent of body weight or percent of time?
body weight
What helps a arthropod keeps it shape?
The exoskeleton of arthropods defines their gross morphology (as determined and maintained by principles of genetic expression); although life stages may evidence significant differences (egg and larval stages, versus adult shape, for example). Since the exoskeleton can't grow owing to its rigidity, arthropods need to periodically shed it in order to increase in size, a process called ecdysis.
What is the formula for calculating the percent of weight loss?
The formula for calculating the percent of weight loss is: (Initial weight - Current weight) / Initial weight x 100.
Convert 0.0141mol percent to weight percent?
To convert from mol percent to weight percent, we need to know the molecular weights of the substances involved. Without this information, we cannot accurately convert 0.0141 mol percent to weight percent.
