A macromolecule is a large complex molecule that has a relatively large molecular weight. There is Carbohydrates, Lipids, Protiens, and Nucleic Acids. They all contain Carbon, Hydrogwn, and Oxygen.
Answer:
(B) semiconservative.
Explanation:
According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.
Explanation:
Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight.
Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
Bones are made up of a framework of a protein called , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body. The amounts of certain vitamins and minerals that you eat, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.
