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.
Answer:
C
Explanation:
During their development, many organisms look similar, suggesting that very different organisms may have a common ancestor. - Think of the human fetal neural / spine development which mirrors other species.
Answer:
The easiest argument is the next one:
Suppose phytochemicals are like money. If I put you in a phone cabin with a lot of money and give you 30 sec to be there collecting as much money as you can, at the end you will collect not all the money and a lot of money will be lost. The same happens whit phytochemicals in supplements there are so many that your body can't use them all.
And other thing is that phytochemicals in supplements comes so concentrated that your body will be overstimulated to take this phytochemicals and that changes your normal digestion, in the time it may looks good...but if you don't take supplements anymore, your body will feel the lost and the physical results would be awull.
The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.
Explanation:
In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".
