<h2>Part 1 Answer</h2>
<u>Limestone is a type of</u><u> sedimentary rock </u>
<h2>Explanation:</h2>
Limestone is a type of sedimentary rock which is composed mainly of skeletal parts of organisms living in water such as coral, forams and molluscs. The major materials of limestone are the minerals such as calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Limestone can turn into the metamorphic rock called marble if the right conditions occur.
<h2>Part 2 Answer:</h2>
<u>Over time limestone </u><u>can be deformed and crystallized</u>
<h2>Explanation:</h2>
Limestone and chalk are mostly made up of calcium carbonate. When acidic rainwater falls on limestone or chalk, these rocks may react with the rainwater, causing the rock to be weathered. With the passage of time if limestone has been squeezed and reshaped by temperature and pressure, its structure and composition changes to form a recrystallised limestone which is called marble.
through spores. These spores are carried by the wind or by other organisms.
A lake that freeze over is helpful to the organisms inside the water because, the solid ice serves as a barrier between the water and the cold air above the water. The ice prevents the chilled air surrounding the water body from getting to the organisms inside the water. <span />
<span>The answer is curve 4. The enzymes reaction mostly depends on the pH value. In the conditions of strong acids the activity of the enzymes moves from zero to maximum when represented in a graph. This analysis of the enzymes from the human stomach is done quantitatively.</span>
