Answer:
Natural Resource.
Explanation:
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals. In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources
ionic bonding.
Ionic bonding<span> is a type of </span>chemical bond<span> that involves the </span>electrostatic attraction<span> between oppositely charged </span>ions<span>, and is the primary interaction occurring in </span>ionic compounds<span>. The ions are atoms that have gained one or more </span>electrons<span> (known as </span>anions<span>, which are negatively charged) and atoms that have lost one or more electrons (known as </span>cations<span>, which are positively charged). This transfer of electrons is known as </span>electrovalence<span> in contrast to </span>covalence<span>. In the simplest case, the cation is a </span>metal<span> atom and the anion is a </span>nonmetal<span> atom, but these ions can be of a more complex nature, e.g. molecular ions like NH</span>4+<span> or SO</span>42−<span>. In simpler words, an ionic bond is the transfer of electrons from a </span>metal<span> to a </span>non-metal<span> in order to obtain a full valence shell for both atoms.</span>
Answer:
b. synthesis of cellular membrane components
Explanation:
Endoplasmic reticulum is a network of membranes fistulas; within the cytoplasm of a eukaryotic cells, where proteins and lipids are synthesized usually connected in continuum with the nuclear membrane of the cell.
The ER is of two kinds the smooth and the rough ER (Endoplasmic reticulum).
Functions of Rough endoplasmic reticulum includes; * Synthesis of protein * Degradation of worn out organelles
While the functions of Smooth endoplasmic reticulum includes; * Synthesis of lipid and steroids * Role cellular metabolism * Storage and metabolism of calcium * Catabolism of toxic substance.
Inference from the functions stated above shows that ER is actively involved in the synthesis of cellular membrane components.
Under the following conditions does mushroom cellobiase generate glucose most efficiently- Temperature- 50 to 55 degree Celsius and pH 4.8.
Cellobiase is an enzyme found in fungi that is used for the last process of breaking down of the cellulose into glucose to produce energy.
As every enzyme works optimally in a certain temperature and pH condition the ideal temperature for the working of cellobiase is 50 to 55 degree celsius and ideal pH is 4.8.
These enzyme is essential for the process of breakdown of cellulose hence organisms like fungi and bacteria possessing this enzyme is only able to digest the cellulose.
