Answer:
Organs of excretion make up the excretory system.
They include the :
kidneys-Blood by-products are filtered out by the kidneys and leave the body in urine form. They are part of the urinary system, which also includes the ureters, bladder, and urethra
large intestine-By-products enter the intestine and leave the body in the form of feces
liver- breaks down harmful substances. It's by-products are excreted into bile or blood.
skin-Sweating eliminates excess water and salts, as well as a small amount of urea, a byproduct of protein catabolism
lungs- oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled
Hope this helps!!!!!!

There is three types of neurons occur. Sensory neurons typically have a long denfrite and short axon, and carry messages from sensory repeptprs to the central nervous system. Motor neurons have a long axon and short dendrites and teansmit messages from the central nervous system to the muscles.
I think the answer should be medulla oblongata or foramen magnum.
The major nerves that leave brain should form a thick cord in the brain stem that called medulla oblongata. Medulla oblongata will pass a big hole in the base of the skull that called foramen magnum. Depends on what part the question asked(bone or tissue), it probably between those two options.
Answer:
The two factors are:
• The kind/type of surface involved.
• The force that the surface are being pushed together.
Explanation:
Friction can be said to be the general term used to describe the force that one surface exert on another when they rub against each other.
When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.
The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
Answer:
When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Invasive species can change the food web in an ecosystem by destroying or replacing native food sources.
