Molting is necessary for arthropods because it allows them to grow and develop. As arthropods grow, their exoskeleton becomes too small and rigid, so they shed it through molting to make room for their larger bodies. This process also helps them repair any damage to their exoskeleton and remove any parasites or infections.
The main factors limiting the size of arthropods are their reliance on diffusion for respiration and lack of internal skeletons for support. As arthropods grow larger, the surface area-to-volume ratio decreases, making it harder to exchange gases through their exoskeletons. Additionally, the exoskeleton imposes physical constraints on their size due to the need for muscle attachment points.
The uterus grow to make room for the fetus. A fetus that doesn't grow - no growth of the uterus.
When arthropods outgrow their exoskeletons, they undergo periods of molting. During molting, an arthropod sheds its entire exoskeleton and manufactures a larger one to take the smaller ones place. Molting is controlled by the arthropods endocrine system. An animals endocrine system regulates body processes by means of chemicals called hormones. As the time of molting approaches skin glanes digest the old part of the exoskeleton and other glands secrete a new skeleton. Whenthe new skeleton is ready the animal pulls itself out of what remains of the original Skelton, this process can take several hours while the new exoskeleton is still soft the animal fills with air or fluids to allow room for growth before the next molting. Most arthropods molt several times between hatching in adulthood. This process is dangerous to the animal because it is vonerable to preditors while their shell is too soft to protect themselves. Most arthropods like to hide during molting or molt at night when less predictors can get them.
Because they have an exoskeleton. Once they get to a certain size, they run out of room and have to shed their exoskeleton.
in the elevator there is a secret room with a skeleton that is where it is
The climax of the story is when the rats managed to get into itchouas room and attack him
walk through the wall next to the skeleton
No, humidifiers do not have germ killing properties. Humidifiers simply add moisture to the air of the room in which they are located. In fact, over use of a humidifier can make the room too moist, which can cause the growth of mold or other bacteria.
it's in the top left hand corner on the poster
yes
Because of the composition of the exoskeleton. It must of necessity be tough to serve its function. Since it is inflexible, the organism has to periodically shed it (moult) in order to grow; a process called ecdysis.
