The reproductive system. It is different in males than it is females.
No, cows and chickens are different species and cannot produce offspring together. They have different genetics and reproductive systems, making it biologically impossible for them to interbreed.
The muscular system and the skeletal system work closely together to produce movement in human limbs. Muscles contract and pull on bones, which act as levers to create movement at the joints. Coordination between these two systems allows for smooth and precise movement in response to signals from the nervous system.
No, you cannot get pregnant from the sperm of a dog. Humans and dogs have different reproductive systems and cannot produce offspring together. Pregnancy can only occur between members of the same species.
Ill give you 3:skeletal,nervous,and muscular
The muscles and bones work together to produce movement but without oxygen and a good heart rate movement would not be possible either.
is a number of linked systems, working together closely ,so that they form a single computer
similar cells work to produce tissues then tissues work together to form organs then organs work together to form organ systems then organ systems work to form organisms!
In most cases, two different species of fish cannot successfully reproduce, as they have different genetic makeup and reproductive systems. However, some species may be able to produce offspring if they are closely related and within the same genus.
The circulatory system brings nutrients and wastes to and from the bone. These systems work closely together to maintain homeostasis.
All human organs work together in systems to filter out toxins and produce and provide oxygen and energy to the entire body.
That is generally true what badac claimed, however I've interbred the two species and there is offspring. I bred a male common toad with a female common frog, the offspring wasn't natural at all. The offspring resulted as a tadpole with tiny legs, only two survived and i released the frog,toad and frogtoads back into the wild. Conclusion- A frog and toad can mate but only in captivity, also they need to be similar e.g. treefrog toad and frog, common toad and frog.
Yes. It is fairly common for hurricanes to produce tornadoes. However, hurricane-spawned tornadoes usually aren't as strong as those produce by other systems.
