How do muscle cells form different types of tissues?
A. Information in the DNA of the nucleus can tell muscle cells how to develop and perform special functions. A group of these cells that perform similar functions become muscle tissue. B. Messages from the heart can tell muscle cells how to develop and perform special functions. A group of these tissues that perform similar functions become muscle organs. C. Information in the RNA of the nucleus can tell muscle tissues how to develop and perform special functions. A group of these cells that perform similar functions become muscle systems. D. Messages from the brain can tell muscle cells how to develop and perform special functions. A group of these cells that perform similar functions become muscle tissue.
because there are 3 types of muscle: smooth, which is found in the digestive system and is not controlled voluntarily cardiac: it's only found in the heart and acts like a rythmic smooth muscle, but continously skeletal: the one that is voluntarily controlled and is responsible for your movement
you can discard B because the heart doesn't send signals to other muscles, you can discard C because RNA is used in cell reproduction and is not responsible for the characteristics you have (although it is a reflection of the DNA byt with different molecules)
The answer is A...
