Why is the enzyme pectinase added during the manufacture of fruit juices? . a. the enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice.. b. the enzyme pectinase enhances the taste of fruit juices, making them more popular.. c. the enzyme pectinase speeds up the breakdown of toxins in fruits, producing more juice.

Answer;

The enzyme pectinase speeds up the breakdown of pectin in fruits, producing more juice.

Explanation;

-Enzyme pectinase speeds up the break down of pectin in plant walls, thus creating more juice.

-Pectinase is an enzyme that catalyzes the breakdown of pectin, a component of the cell wall in fruits such as apples and oranges.

-It is used for multiple purposes during the manufacturing process of our favorite juices.

-It clarifies naturally cloudy juices, improve the aroma, extracts more colors, and is often used in the preparation of berries, tropical fruits, and apples & pears.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
