Answer:
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
Sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones.
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

According to the punnet square, if you combine a parental homogeneous dominant trait and a heterogeneous trait. 1 out of the 4 boxes will be homogeneously recessive.
The tilt of the earth's axis, which essentially "turns" certain parts of earth so that some parts receive more direct sunlight
Answer:b. an mRNA transcript to which multiple ribosomes are attached
Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.
Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.
