Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
Answer:
No, eukaryotic cells cannot live without mitochondria and chloroplasts; they provide the energy cells need to survive.
Explanation:
It is not possible today for a eukaryotic cell to live without mitochondria or chloroplasts since these are the organelles responsible for providing the energy cells need to survive.
Mitochondria are the organelles that synthesize energy in cells. Chloroplasts are the organelles that contain chlorophyll and where photosynthesis takes place in a cell.
Answer:
D) Energy is required in order to maintain homeostasis--without a constant, organized internal state, the cell will die.
Explanation:
Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance.
Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping at an appropriate temperature (37º C) ensuring that the necessary changes to the body occur; and thus the cells of the body develop.
Because of homeostasis, cells need a constant supply of energy. That's because energy is needed to maintain homeostasis - without a constant, organized internal state, the cell will die.
Erosion? I took earth environmental 2 years ago so I might be wrong
