Nadia is digging a hole in her backyard to plant a new tree. As Nadia is digging, she notices that there is only a six-centimeter layer of soil, but then it turns to mostly clay and
becomes more difficult to dig. She notices that there are many different types of small insects living in the layer but almost nothing living in the clay layer. She tests the pH of the
soil to ensure that the tree will survive and notes that the pH is 6.7.
If Nadia kept digging deeper in her backyard, which type of soil would she eventually encounter?
bedrock fragments
humus layer
subsoil
topol

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
