Answer:
The percentage of space not occupied by solid matter in soil is called :
B. Porosity.
Explanation:
- Porosity is represented as the percentage of void in the soil.
- In simple words, it is the number of pores present in a soil.
- The porosity of soil is a factor that determines the quality and suitability of the soil for agriculture.
- A more porous soil does not hold lot of water and nutrient while a less porous soil retains water and nutrient.
- Thus neither a extremely porous nor a less porous soil is suitable for agriculture.
Amylases' main function is to hydrolyze the glycosidic bonds in starch molecules.
<h3>Which molecule is hydrolyzed and digested by amylase?</h3>
Amylase is an enzyme that separates glucose molecules from starch. Both plants and animals use amylase when digesting starch. amylase, any limb of a class of enzymes that imbues the hydrolysis (splitting of a compound by the inclusion of a water molecule) of starch ...
Amylase is any member of a class of enzymes that activate the hydrolysis (splitting of a compound by the limb of a water molecule) of starch into smaller carbohydrate fragments such as maltose (a molecule composed of two glucose molecules).
So we can conclude that Amylases are usually referred to as a class of enzymes that catalyzes the hydrolysis of starch into glucose and maltose.

answer:
by having a high genetic level of melanin in your skin, you're skin is more protected from the ultra violet sun rays. Darker skinned races have more melanin present, these races originate from hot countries where sunlight is often present; the production of melanin in their skin allows them to reflect and inhibits they're skin from becoming extremely damaged. Light skinned races don't have a large amount of melanin due to they're native countries lacking sunlight. This is an evolutionary adaptation of the human race.
1. The correct answer is; are body cells is going to shrink. <span>Salty seawater is a hyperosmotic solution, meaning that it has more solutes than the cell inside. The water will move (from the cell) via osmosis in order for the solutions to reach equilibrium. Also, salty solution exerts more pressure on the of the cell, so the cell will shrink.</span>
<span>
2. The correct answer cells in the fish will stay the same size. This will occur because both solutions, freshwater lake and river have similar (or equal) solute concentrations. Those solutions are called isosmotic. There is no movement of water or the solutes, so the cell stays the same.</span>
3. The correct answer is to swell. <span>This will happen because sea star egg has the same solute concentration as its first environment-ocean meaning that this solution is hyperosmotic comparing to the lake (ocean is saltier than the lake, it has more solutes). When you put the sea star egg in the lake, the water from the lake will move (via osmosis) into the egg, to reach equilibrium. Water will cause the cell to swell.</span>
