I go with Ice Core examples since early sociteties probably didn't have Written Records or maps, and tree rings would only tell if they were fossilized. I hope this helped :)
The lysosomes are responsible for that
Answer:
C.
Explanation:
This is because asexual reproduction has no genetic variation.
Both plant and animal cells have a mitochondria! Plant cells have a cell wall, a cell membrane and a chloroplast. Animal cells have a lysosome, where as plant cells usually don't have this present.
Answer:
G and K
Explanation:
Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.
This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.
In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
