Cladogram shows that Osteichthyes should be under group A. Going back to their characteristics, they’re a group of fish that have the derived characteristics of jaws and true bones. So, moving backwards from group A these derived characteristics are clearly traceable, wherein each line is showing a relationship/connection.
The answer is Anthropogenic
Instances of anthropogenic activities (human activities) that have resulted in climate change include burning of fossil fuels that have increased the levels of carbon dioxide and carbon monoxide in the atmosphere. The gases create a greenhouse effect and cause climate change.
Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.
Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
Mitosis, or cellular division and reproduction.
