Why heating a can and putting it in water?
Heating a can and then submerging it in water can create a pressure difference between the inside and outside of the can. When the can is rapidly cooled in water, the pressure difference causes the can to collapse due to the external pressure being greater than the internal pressure.
Is the uterus internal or external?
The uterus is an internal reproductive organ in the female reproductive system. It is located in the pelvic cavity between the bladder and the rectum.
What is the difference between the two types of respiration?
External respiration refers to the exchange of gases between the lungs and the blood, while internal respiration is the exchange of gases between the blood and the tissues. External respiration involves the intake of oxygen and release of carbon dioxide in the lungs, while internal respiration occurs in the body's tissues.
What interaction between organisms would be described as parasitic?
Parasitic interactions involve one organism benefiting at the expense of another organism. The parasite benefits by obtaining nutrients or shelter from the host, while the host is harmed in the process. Parasites can be external, like ticks and fleas, or internal, like tapeworms and parasitic fungi.
What is the difference between osmoregulators and osmoconformers?
Osmoregulators actively control their internal osmolarity regardless of external conditions, while osmoconformers allow their internal osmolarity to match their external environment. Osmoregulators are typically found in environments with fluctuating salinity, while osmoconformers are more common in stable environments.
