That we all came from a common ancestor.
Newtonian gravity is what scientists believe will stop the universe’s expansion. This attraction would have to overcome the propulsive force of dark energy expansion, thus causing the compression of all the matter in the universe back into a small, hyperdense singularity.
Answer:
D) Insulin
Explanation:
Insulin is an organic molecule, specifically a protein molecule, which is produced by the pancreas. It is an enzyme that regulates the level of glucose in the blood. Insulin carries out this function by converting excess glucose in the blood into a stored form called GLYCOGEN.
The glycogen, which is stored in the liver, is converted back to glucose when the need arises for glucose in the blood. Hence, INSULIN is that large organic molecule (protein) that helps to maintain glucose levels in the blood and is released from the pancreas.
Answer:
The fluid mosaic model was used to explain the structure of the cell membrane. This model was well accepted model and given by Singer and Nicolson.
According to this model, the cell membrane is composed of lipids and proteins. The lipid layer is arranged and the proteins are inserted or span the bilayer. Some proteins are trans-membrane proteins, peripheral proteins and integral membrane proteins. Cholesterol are also inserted in this membrane. The carbohydrates are present in association with proteins or lipids on the cell membrane.
