1-A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
2-Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic.
3-Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. When lava comes out of a volcano and solidifies into extrusive igneous rock, also called volcanic, the rock cools very quickly.
4-Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground.
I agree with the other person “Radiation. Both conduction and convection transfer energy through matter. Radiation is the only way of transferring energy that doesn't require matter. Radiation is the transfer of energy by waves that can travel through empty space.”
Answer:
The correct option is<em> B) Meiosis provides for chromosomal variation in the gametes produced by an organism.</em>
Explanation:
Meiosis can be described as a cell division process by which the chromosome number gets reduced to half. This is because half of the chromosomes will come from the female parent and half of the chromosomes will come from the male parent in the offsprings that will be produced when they interbreed.
During the process of meiosis, crossing over and homologous recombination of chromosomes occurs which allows genetic variations among species.
