D bacteria are the main nitrogen transporters
Answer:
D
Explanation:
Vegetation on soil protects the soil from erosion because its roots and root hairs help bind the soil particles together. This occurs mechanically by binding soil into crumbs and also chemically by providing organic matter that binds the soil particle into humus that holds moisture. The soil becomes heavy to be carried off by wind erosion. Trees also break the down flow of water hence reducing the capacity of runoff to carry soil sediments.
Myofibrils are the building blocks or contractile unit of each muscle fiber. The tiniest functional unit of skeletal muscle, the sarcomere, is found in the myofibrils and is made up of protein filaments: actin (thin) and myosin (thick).
The appropriate answer is B. Throughfall. These nutrients are transported via the process of throughfall where rain flows from leaves to the ground. Rainforests receive high annual rainfall. The leaves are also designed to funnel water to the ground soon after a shower. Leaves are equipped with drip tips to allow water to roll of leaves easily. Any particles deposited on leaves are going to be washed to the forest floor by frequent rainfall that occurs here.
