B. After many years, groundwater discolors and changes the rock.
C. Over a long period of time, temperature and pressure build up and change the rock.
D. Over time, layers form and spread out over a wide area to form rock.
Answer:
Option (C)
Explanation:
Sedimentary rocks are formed due to the compaction and lithification sediments. For example, mudstone, sandstone, and shale.
Metamorphic rocks are those rocks that are formed when a sedimentary/igneous/other metamorphic rocks undergo changes in the pressure and the temperature conditions. Temperature and pressure are the main factors here. For example, slate, phyllite, schist, and gneiss.
Mudstone is a sedimentary rock that can convert into a fine-grained and foliated metamorphic rock called slate due to the increase in the temperature and pressure.
Hence, the correct answer is option (C).
C is the answer.
Metamorphic rocks is when a rock changes under time and lots of pressure.
Sedimentary is rocks made of sediment.
Igneous rocks are rocks that are made of magma.
Knowing this, C is closest to the definition of metamorphic rocks.
In metaphase II, the chromosomes line up in the middle of the cell.
In prophase II, DNA is replicated and spindle fibers attach to the chromosomes.
In metaphase II, DNA is replicated and spindle fibers attach to the chromosomes.
In metaphase-II of meiosis, chromosomes are aligned in the middle of the cell. Option B is correct.
It is a type of celldivision in which cells divide to form four haploid daughter cells. It is found in the germcells of organisms.
The process is completed in two phases,
Therefore, in metaphase-II of meiosis, chromosomes are aligned in the middle of the cell. Option B is correct.

Answer:
Moths make use of several self defending techniques to avoid predators.
Explanation:
Most people often confuse moth with butterflies, but moth are a different member of Lepidoptera, an flying insect. There are many ways through which moth protect themselves from predators.
Since moths are usually active during the night time, so they often hides in the day time from predators. Another technique that moths use is camouflage, where they can confuse the predators by blending into the surrounding. And when a predator us unable to see a moth, its life is saved. Apart from this, moths are even clever enough to trick bats by their strong detection power.
