Answer:
Explanation:
The main function of the plasma membrane is to protect the cell from its surroundings. Made of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules it also regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries. Membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors, which then trigger intracellular responses. Some viruses, such as Human Immunodeficiency Virus (HIV), can intercept these receptors to get into the cells, causing infections.
Answer:cell wall
Explanation:The cell wall in plant cell is made of cellulose and functions to provide rigidity to the cell. Cell wall has no living function
Answer:
the endpoint not pH scale is 14
<span>When used in glaucoma, this drug blocks beta-1 and beta-2 adrenergic receptors resulting in decreased aqueous humor production: Timolol
Beta blocker is common medication in glaucoma, but many beta blocker is selective to beta-1 or beta-2. Nonselective beta blocker would be timolol.</span>
The answer is : Light waves would be more likely to be refracted or diffracted, thus failing to reach plants and phytoplankton
Sunlight is needed by the producer(plants, phytoplankton) in the ocean to do photosynthesis. When an are is attacked by severe storm, the area will be covered by cloud of the storm which impede the light, cause it to be refracted or diffracted. This will cause less light comes to the producer of the plants and phytoplankton.
