Explanation:
Metamorphism describes how one type of rock is changed into another. Schist, a metamorphic rock is produced by adding heat and pressure to mudstone or shale, thus it is metamorphic; the extreme pressures during its creation fire the quartz grains, flat minerals and feldspar into large-grained rock. As metamorphism increases, i.e. pressure and temperature, the size of the crystals and how coarse the folding or foliation increases.

Answer:
- <u>Option:(1)-</u>The <u>Genetic drift </u>theory is an evolutionary concept that suggests that behaviors that help an organism survive are passed on while weak behaviors are lost.
Explanation:
According to this theory, an organisms faces different levels or kinds of environmental factors, which either suppresses or increases the level of a certain allele frequency inside an organisms genetic sequence, which then results in the change in behavior of that organism. And through many generations the changes in behavior may pass on from one to another, as the changes does not occur in a single generation.But, the alleles frequency are suppressed and increased with time, when they face different environmental factors or situations.

Answer:
mass of hot water must be 
Explanation:
The change of heat contained in hot and cold water will be the same.
Thus,
Δ
Δ
Change in heat content is equal to the product of mass of the substance, specific heat capacity and change in temperature.
Substituting the given values in above relations, we get -
C value is constant for water irrespective of water being hot or cold. So the formula becomes -
