Explanation:

The polysaccharides are the sugar polymers that contain more than 20 monosaccharide units. Here, two monosaccharide units are joined together by a glycosidic bond. Examples of polysaccharides include cellulose, starch, glycogen, etc.  

The molecules are can dissolve in water are said to be hydrophilic or polar molecules while the hydrophobic molecules repel water and are not dissolved in it. Glucose is dissolved in water while fats are hydrophobic macromolecules.  

Maintaining the internal body conditions within the narrow range is called homeostasis. Homeostasis of metabolic reactions is maintained mainly by negative feedback regulation. Accumulation of the product of a reaction inhibits the reaction itself to maintain the constant internal bodily conditions.

A macromolecule is the large molecules and consists of thousands of atoms. Most of the macromolecule are polymers and are made of many joined small organic compounds called monomers. For example, protein is a macromolecule and is made of many amino acids joined together by peptide bonds.

The cytosol is the fluid present between the plasma membrane and the nucleus of the cell. Cytosol and suspended organelles together make cytoplasm. Cytosol serves as a site for metabolic reactions. Pseudoscience relies on statements that can not be proved by scientific experiments or do not have a scientific basis.  

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
