A strand of mRNA is the compliment to the coding strand of DNA. It kind of has the opposite information from DNA (if a DNA strand is TCCGATC the compliment mRNA would be AGGCTAG). This way, it is able to retain the information when travelling to the ribosome for translation (aka, turning the DNA information in proteins)
Species change over time. -The mechanism that produces the change is natural selection: the differential survival and reproduction of individuals based on variation in their traits. Natural selection acts on individuals but individuals do not evolve; their descendants do.
The embryo, endosperm and seed coat.
Answer:
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
Explanation:
Trophic cascades are powerful indirect interactions that can control entire ecosystems
