I'm guessing true, that's what my teacher says
Answer:
Coombs reagent is an antiserum with antibodies that bind to the human <u>antibodies attached on the surface of the erythrocytes.</u>
Explanation:
Coombs test is a blood test used in immunology and immunohematology. It is of two types: direct and indirect.
The Coombs reagent is an antiserum, containing antibodies.
The direct Coombs test detects the antibodies present on the surface of the erythrocytes.
In this test, when the Coombs reagent is reacted with the blood to be tested, <u>the antibodies in the Coombs reagent binds to the antibodies attached on the surface of the erythrocytes in the test blood and cause agglutination.</u>
Answer:
A community is an interacting group of various species in a common location.
None of the above.
Erosion is more likely to increase when the amount of vegetation decreases. The potential for soil erosion increases if the soil has no or very little vegetative cover of plants.
Plants and their residue form a cover that protects the soil from direct raindrop impact and splash, tending to slow down movement of runoff water and allows excess surface water to infiltrate, preventing erosion by water.
Plants root systems tend also to anchor top soil in place such that it is firm and cannot be easily blown away by wind thus preventing erosion by wind.
