What is the adaptive significance of the seta of the sporophyte growing well above the mat of the gametophytes?
Homework Answers
Three main adaptive significance of seta of the sporophyte is :
1. It gives Better dispersal of spores.
2. seta is Taller and so is helpful for wind to take spores away.

After assessing the children, they all appear to be growing well, and you see no concerns. However, as you review your findings with Tonya, she has some questions. Her husband recently lost his job, and money is tight. Tonya is thinking about switching Trey to cow’s milk rather than formula to save money. She is also concerned because Dana is not eating as well as she had previously. After obtaining further information you feel that Dana is experiencing some common...
