Answer:
A glance of earth taken from space will depict it blue. This blue colour is actually water, the major part of the earth is covered with water. We need water for almost everything, for example- drinking, bathing, cooking etc and therefore we should know about the properties of water. 65 % human body is composed of water. Water is essential for the survival of life on earth. Water is distributed unevenly on the earth’s surface. It forms a major solvent and dissolves almost every polar solute. So let us have a look at its properties.
Physical properties of water : Water is a colourless and tasteless liquid. The molecules of water have extensive hydrogen bonds resulting in unusual properties in the condensed form. This also leads to high melting and boiling points. As compared to other liquids, water has a higher specific heat, thermal conductivity, surface tension, dipole moment etc. These properties form the reason for its significance in the biosphere. Water is an excellent solvent and therefore it helps in the transportation of ions and molecules required for metabolism. It has a high latent heat of vaporization which helps in the regulation of body temperature
Chemical properties of water: Amphoteric nature:
Water can act as both acid and base, which means that it is amphoteric in nature.
Example:
Acidic Behaviour: H2O(l)+NH3(aq) ⇌ H3O+(aq)+NH+4(aq)
Basic Behavior: H2O(l)+H2S(aq) ⇌ H3O+(aq)+HS−(aq)
Redox reactions:
Electropositive elements reduce water to hydrogen molecule. Thus water is a great source of hydrogen. Let us see an example in this case:
2H2O(l)+2Na(s)→2NaOH(aq)+H2(g)
During the process of photosynthesis, water is oxidized to O2. As water can be oxidized and reduced, it is very useful in redox reactions.
Hydrolysis reaction
Water has a very strong hydrating tendency due to its dielectric constant. It dissolves many ionic compounds. Some covalent and ionic compounds can be hydrolyzed in water.

Answer
Just think critically about why (if you were an egg laying species), having a fetus/baby develop inside of you would be advantageous.
For one, eggs are much less protected from outside factors such as predators, temperature, etc than live birthed creatures. Live birth provides protection inside the mothers body from things such as heat, cold, moisture, predatory animals, etc. An egg laying animal must keep its eggs at a perfect temperature and check to make sure no other animal has eaten them.
No estoy seguro que decir, pero sí es difícil
The active site’s primary function is to bind with the substrate molecule to undergo a chemical reaction.
Answer and Explanation:
Enzymes are organic catalysts which are protein in nature. There are two types of naming enzymes:
<h3>Trivial naming</h3>
This method involves giving enzymes names based on the names of the persons who discovered them. The names of such enzymes end with the suffix-in, for example, pepsin, trypsin. Some of these names have been retained to date.
Enzyme Nomenclature by Enzyme Commission
This is the modern method of naming enzymes. The suffix-ase is added to the substrate or the reaction which the enzymes catalyses. Every enzyme code consists of the letters "EC" followed by the enzyme. For example
EC 1 oxidoreductases- oxidoreduction reactions
EC 2 transferases- transfer of a functional group
EC 3 hydrolases- catalyse hydrolytic cleaving
EC 4 lyases - adding groups to double bonds. e.g., C-C,C-O
EC 5 isomerases - catalyse structural changes in a molecule
EC 6 ligases - joining of two molecules
