Which statements explain the relationship belween photosynthesis and cellular respiration? Check all that apply
Sedaia [141]

Answer: The third and fifth statements are true. Oxygen released from photosynthesis is breathed in by animals to break down glucose, and the carbon dioxide released by animals is used to build glucose in photosynthesis.

Explanation: Oxygen and glucose are the reactants for cellular respiration in animals. Oxygen is breathed in through the air, which is produced by plants. When the process of cellular respiration is complete, animals breathe out carbon dioxide as a product, which plants need to perform photosynthesis. Plants perform photosynthesis and send oxygen into the environment. The reactants of photosynthesis are the products of cellular respiration in animals, and vice versa, but the reactants and products are not the same.

Use the correct terms to complete the sentences that explain how the fluid mosaic model of a membrane works.
Ierofanga [76]
<h3>Answer:</h3>

The Fluid Mosaic Model declares that membranes are formed of a Phospholipid Bilayer with several protein molecules drifting about inside it. The ‘Fluid’ section describes how any components of the membrane can run nearby loosely if they are not connected to different components of the cell. The ‘mosaic’ section explains the ‘patchwork’ of proteins that are detected in the Phospholipid Bilayer.

<h3>Explanation:</h3>

There is a lipid bilayer in which the protein molecules are embedded. The lipid bilayer gives fluidity and elasticity to the membrane. Carbohydrates are also found in a cell membrane. The plasma membrane is said to be two-dimensional structure or liquid we can say which does not allow the lateral diffusion of membrane components. The plasma membrane has the texture of vegetable oil at body temperature, because of which the proteins and other substances move across it. That's why the plasma membrane is described as using the fluid-mosaic model.
