The Smooth Endoplasmic Reticulum has a wide range of functions in carbohydrates and lipid synthesis. Phospholipids and cholesterol are necessary for the construction of cell membranes. It serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells, Smooth ER helps detoxify certain compounds. In muscle contraction, and in brain cells it synthesis male and female hormones.
Answer:
No osmosis occurs. Red blood cells placed in a solution with a higher water concentration compared to their contents (e.g pure water) will gain water by osmosis, swell up and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
The chemical bonds that hold atoms within a molecule of water together are D. Covalent bonds. These are bonds whereby electrons are distributed among the hybridized orbitals and are shared among the subsequent atoms.
Answer:
photosynthesis
Explanation:
Photosynthesis is the process used by algae, green plants and some types of bacteria to convert solar energy into chemical energy. During photosynthesis, carbon dioxide (CO2) is consumed and oxygen (O2) is released. In the primitive Earth, the photosynthetic marine organisms helped to replace atmospheric CO2 with O2, which was one of the most important gas components in the atmosphere. Moreover, the ozone (O3) is generated when O2 reacts with sunlight. In the stratosphere, this gas (O3) formed a layer that is capable of filtering ultraviolet harmful radiation.
