Answer and explanation;
-The hydrogen bonding in water is a a result of partial negative charge on the oxygen of one molecule which forms a hydrogen bond with the partial positive charge on the hydrogen of other molecules.
-When molecules of water are close to each other, their positive and negative regions are attracted to the oppositely-charged regions of nearby water molecules. This force of attraction is called a hydrogen bond. Each water molecule is hydrogen bonded to four others.
-This important property of hydrogen bond occurs in polar molecules such as water which contains weak, partial negative charge at one region of a molecule and also a partial positive charge elsewhere in the molecule.
Glyco means carbohydrate. Glycoproteins have carbohydrate attached to protein, whereas Glycolipids have carbodrate attached to lipid (like fatty acids).
The correct answer is - D. all of these.
The collaboration between different types of organisms in nature is not something weird, it actually happens quite a lot. When we have a situation where two or more organisms have developed a relationship from which both of them benefit, we are talking about mutualistic symbiotic relationship.
The flowers and the pollinating animals are perfect example of this type of relationship. The flowers develop certain color or smell that will attract certain type of the pollinators. They will be attracted by the flower and pollinate it. The flower will become fertilized in that way, while the animal will get food source. Also, the pollinating animal will disperse the pollen in the surrounding area.
Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy and the cell membrane lets it do just that.
The cell membrane is a lipid bilayer that prevents that passage of water and ions. This lets cells to maintain a higher concentration of sodium ions out the outside of the cell.
Mainly to control the movement of substances in and out of the cell. It’s selective so it only allows certain molecules inside such as small molecules like water.
