Answer:
Diagram D
Explanation:
When electrons absorb energy, they move to higher orbital levels. The highest energy levels are the furthest from the nucleus. More energy is needed to occupy higher energy levels. Therefore, the electron which must have absorbed the most energy is in Diagram D. In this diagram, the electron absorbs enough energy to move it from n = 1 to n = 4.
Answer: Carbonic acid
Explanation:
The process of respiration of the terrestrial organism and marine organism leads to the exchange of gases. Due to exchange of gases, there is an entrance of carbon dioxide into the ocean and oxygen out of the ocean.
The addition of carbon dioxide into the water causes acidification of water and oxygen is diffused out of the water.
Hence, the product formed at Point A is carbonic acid.
Plants absorbs inorganic ions such as carbon dioxide by the process of gas exchange and water by the process of osmosis which converts into glucose and oxygen in the presense of sunlight and chlorophyll.Light is absorbed by the chlorophlasts present in green leaves.

Answer:
Aerial roots allow the orchid to attach itself to trees
Explanation:
Orchids are a group of plants that are mostly epiphytic in nature i.e. depends on other plants for physical supports. According to this question, orchids have evolved to develop a novel feature called AERIAL ROOTS.
This specialized kind of roots serves different functions in the orchid plants but however, the most likely is for PHYSICAL SUPPORT. The orchids use their developed aerial roots to climb and attach itself to their tree host in order for them to reach sunlight.
