In the light reactions, H2O goes in, and O2 goes out.
Endosymbiotic theory is a theory of evolution that eukaryotes came from prokaryotes. Mitochondria and chloroplasts both have the double membranes. Each of them also contain genetic material that are replicated with a separate cell cycle. Both organelles have their own ribosomes.
Answer:
-use PCR to amplify the gene for GFP
-perform a restriction digestion of the GFP gene and the plasmid
-ligate together the GFP gene and the plasmid to generate a recombinant plasmid
-transform bacteria with the recombinant plasmid using electroporation
-plate the bacterial cells, and screen for positive transformants
Answer:
Due to no resistance.
Explanation:
Most mosquitoes perish when DDT chemical was sprayed the first time because these mosquitoes are vulnerable to the DDT chemical and there is no resistance present in their body against this chemical. DDT chemical is an insecticide which is used against insects or pests that causes damage to human, organisms and crops. DDT was first synthesized in 1874 by the Austrian chemist named Othmar Zeidler.
Many theories can never be proven.
Here are a few examples:
-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.
None of these statements can be proven. That's why they're not called
Facts or Laws.
It also tells you that some pretty powerful stuff has been done with concepts
that can't be proven. If you want to make an idea look foolish, that doesn't
happen when you say "it's only a theory".
