A biologist would most likely concentrate on homologous features to find and analyse an evolutionary relationship between two species, finding homologous traits between species might help biologists to understand the evolution of animals, whereas concentrating on analogous features might help to compare the evolution of different species. Hope this helped!
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
Since the Action AA batteries last 4 times as long as Bonus AA ones, even though they cost four times as much for convenience in only having to change them once compared to 4 times for the same length of time, this is a good reason to buy them. This is especially the case if the batteries are being used in a remote place such as by a geologist with a GPS out in the bush then he/she doesn't have to worry about them running down so much.
They have hooks so that the seeds can spread around, get carried away and land in a place be planted and grow.
