In water molecule the electrons between the oxygen and the hydrogen are shared, but the sharing is not equal. Oxygen pulls electrons slightly towards itself. Therefore, the electrons are more near the oxygen, making that part of molecule(oxygen part) slightly negative. Since the electrons are not near the hydrogen so, that part of the molecule is slightly positive.
Answer:
A parasites is known to cause malformations, but only when it attacks tadpoles at a certain point in their development. Predators can cause missing or shortened limbs, as a partially eaten tadpoles regenerate lost tissues.
Answer:
A. glucose
Explanation:
In cellular respiration, electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step.
Answer;
-Proteins play a role in transport, enable movement, provide structure and support, and help make chemical reactions happen.
-Nucleic acids carry genetic information, determine the structure of proteins, and help build proteins.
Explanation;
-Biological macromolecules are the large molecules necessary for life, include carbohydrates, lipids, nucleic acids, and proteins.
-Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules.
