(Q029) Which of the following statements is FALSE? Group of answer choices Formins promote the formation of unbranched actin filaments. Actin filaments are usually excluded from the cell cortex. Integrins are transmembrane proteins that can bind to the extracellular matrix. ARPs can promote the formation of branched actin filaments.

- Actin filaments are usually excluded from the cell cortex

Explanation:

In eukaryotic cells, actin proteins polymerize in order to form filaments. These actin filaments can be localized beneath the plasma membrane, where they form a network that helps to provide mechanical support. This network localized on the inner face of the plasma membrane is called 'cell cortex', which is a specialized structure that is attached to the cell membrane by Ezrin, Radixin and Moesin (ERM) proteins. The cell cortex plays key roles by controlling the cell shape, cell morphogenesis and membrane behavior.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

genetic variation will increase because of a new habitat and food source.
