Answer: Mycorrhiza
Explanation: Mycorrhiza is a symbiotic relationship between a plant and a fungi. Nearly 80 percent of all plants with root systems participate in this mutualistic relationship. In mycorrhiza, the fungus forms a haustoria that penetrates the cell walls of the plant's roots. The fungus absorbs all the nutrients from the roots as they are transported to the plant. In return, the fungus gives the plant necessary chemicals and minerals that it cannot properly reach on its own.
<span>Chemical weathering occurs more rapidly in a hot and wet climate. Chemical processes like chemical weathering happens rapidly during high temperature, specifically during warm but damp climates. So, on the first question, the answer is letter A. On the second question, the statement that best describes rill erosion is letter D. Rill erosion is the removal of soil by a running water that cuts and forms small channels into a slope or streamlets.</span>
Because an antibody is "made" relative to the antigen, but kept at low levels when you are exposed the first time ("primary immune response"). The second time you're exposed to the same antigen, memory cells recognize it and the body produces a high level of antibodies, and the level of antibodies usually remains higher for a longer time ("secondary immune response"). This is your basic immune response (primary and secondary).
This explains exactly why vaccines are effective to extremely effective.
Trypins breaks down the protien into simple amino acids which are absorbed by the gut wall.
