Answer the following question given this paragraph: In 1869, a Russian scientist named Dmitri Mendeleev created the periodic table , which is a way of organizing elements according to their unique characteristics, like atomic number, density, boiling point, and other values ( Figure below ). Each element is represented by a one or two letter symbol. For example, H stands for hydrogen, and Au stands for gold. The vertical columns in the periodic table are known as groups, and elements in groups tend to have very similar properties. The table is also divided into rows, known as periods. Q: Who created the periodic table? Choices: - Isaac Newton - Gregor Mendel - Niels Bohr - dmitri mendeleev A:
(Answer)
dmitri mendeleev

Answer the following question given this paragraph: At the end of the Cretaceous Period, or 65 million years ago, all dinosaurs (except those which led to birds) went extinct. Some scientists believe a possible cause is a collision between the Earth and a comet or asteroid. The collision could have caused tidal waves, changed the climate, and reduced sunlight by 10-20%. A decrease in photosynthesis would have resulted in less plant food, leading to the extinction of the dinosaurs. Q: A comet striking the earth may have caused mass extinction, this would have decreased sunlight, which would have effected what plant process reducing food? Choices: - fertilization - decomposition - glycolysis - photosynthesis A:
(A).
photosynthesis
Ques:Answer the following question given this paragraph: The nucleus is an example of an organelle . An organelle is any structure inside a cell that is enclosed by a membrane. Eukaryotic cells may contain many different organelles. Each does a special job. For example, the mitochondrion is an organelle that provides energy to the cell. You can see a mitochondrion and several other organelles in the animal cell in Figure above . Organelles allow eukaryotic cells to carry out more functions than prokaryotic cells can. Q: Any structure inside a cell that is enclosed by a membrane is called? Choices: - an article - a particle - an enclave - an organelle A:

Ans:an organelle

Answer:
solutes
