I would say (2)... oxygen is a byproduct that plants produce when they are making glucose. Plants are autotrophs
Answer: The answer is B.
Explanation: The answer is B because the muscle tissues vary with function and location in the body.
Some of the carbon atoms in the glucose exit the leaf as carbon dioxide during respiration while other carbon atoms are used to make important parts of the plant, such as additional leaves or wood. Carbon atoms that remain in leaves will either fall off (during plant senescence) or become a meal for an animal. Hope this helps
Opposite charges of polar molecules can interact to form hydrogen bonds. The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F. <span>These very highly electronegative</span><span> </span><span>elements</span><span> create a partial positive charge on the hydrogen. </span><span>The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.</span>
However, the hydrogen bond is a strong intermolecular bond.
Answer:
That would be the sun, because of its gravitational pull its what pulled the other planets closer, then making our solar system. However, the sun was formed after the solar nebula, but thats not an option, so the next thing made was the sun. I hope this helps you! :D
