The water depth may may have dropped , if the same aquifer is being pumped aggressively by many pumps, it can deplete the aquifer to the point where certain pumps will start to “run dry” temporarily. . Or water evaporating
Deciding how the world should be
choices are:
Mike is right because the atomic mass of lithium is 6. There are 3 protons and 3 electrons in the atom. 3+3=6
Joan is right because the atomic number of carbon is 6. There are 3 protons and 3 electrons in the atom. The atomic number shows the number of protons plus the number of electrons. 3+3=6
Joan is correct because carbon is a neutral atom. There are the same number of protons and electrons in the atom pictured.
Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
Li has atomic no. 3 and mass 7. so the correct ans is Mike is correct because the atomic number shows the number of protons in all atoms. There are 3 protons and the atomic number of lithium is 3.
A is the answer. This answer is also a question, and the answer to that question is 0.25
Answer:
b. False
Explanation:
<em>Caenorhabditis elegans</em> is a well-known species which is widely used in genetic experiments (i.e., it is a model organism). <em>C. elegans</em> is a soil nematode that eats bacteria, but its survival depends on the ability to distinguish toxic from non-toxic ones. <em>C. elegans</em> cannot feed <em>Bacillus thuringiensis</em> because this bacterium produces a toxin Bt protein that damages its gut, thereby producing the death of this nematode. Interestingly, it has been proposed that Bt toxin pathways might be exploited for the design of new generation nematicides.
