Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily
These organisms convert nitrogen in the soil to ammonia, which can then be taken up by plants. This process also occurs in aquatic ecosystems, where cyanobacteria participate. After nitrogen has been fixed, other bacteria convert it into nitrate, in a process known as nitrification.

That would be ascomycota or sac fungi. Sac fungi are characteristically known for producing ascus. This is a sac-like structure that contains haploid spores called ascospores. Some examples of sac fungi are yeast, truffles, morels and dead man's fingers.
I’m pretty sure The answer Is D. I did the test not to long ago and I got it all right. :)

Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions.
