The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice. It speeds up breakdown of pectin in plant cell walls, thus creating more juice. It is also used in wine making to avoid cloudiness
The correct answer is D. Cryogenian period
Explanation
The Cryogenian period (720 million years ago) is known as the period in which the first animals of the earth appeared, which were identified using fossils, these animals were multicellular organisms similar to sponges. Scientists claim that they can be ancestors of modern animals or extinct organisms of which nothing is known and that diversify into multiple forms during the Ediacaran period. So, the correct answer is D. Cryogenian period
Answer:
<u>3. exothermic, because the products are at a lower energy state in the reactants</u>
Explanation:
It is also because the average enthalpy is negative.
since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
Antibodies are immunoglobulins which are directed against specific antigens present on foreign substances or on pathogens.
Answer:
Each ion or charged molecule in a fluid contributes to the fluid's overall electric charge. A difference in charge between two regions of fluid can affect the rate and direction of diffusion between them. For example, positively charged substances will tend to diffuse toward a region with an overall negative charge.
