Please count, please!! I will give 75 points. It is necessary to paint in detail!:: The 3rd question - you found herd of hoofed animals on other party of a watering place.

(you lioness):: The 5th question - during the first hunting you took away young lions to a watering place. But there was a buffalo. He did not like your presence and he runs on you. What will you make? (you lioness):: The 6th question. - You have to show to young lions during their training as they have to hunts. What will you make? (you lioness):: 7, a decisive question - you and 2 young lions on a watering place. Behind the adult, lonely male approaches you. Young lions notice him and publish silent roars. The lion does not maintain and rushes on young lions. What will you make? (you are a lioness)

It is known that certain conditions are necessary for development of sprouts. Sofya decided to find out a role of one of such conditions, having made experiment with seal of seeds to the soil. On a box bottom she filled a soil layer 4 cm thick and put previously wetted haricot seed. Then over it filled one more soil layer 4 cm thick and put two seeds of haricot. So it did three more times, and it put the last seed on the surface of the soil. Within two weeks she regularly watered the soil in a box and monitored development of sprouts. Sofya displayed results of the experience in the drawing. What influence of a factor on development of sprouts illustrates this experience?
