"Alkenes can be used to make polymers. Polymers are very large molecules made when smaller molecules join together, end-to-end. The smaller molecules are called Monomers. In general: lots of monomers molecules ----- a polymers molecule"
Light reaches organisms in the photic zone, where microscopic Phytoplankton and multicellular algae provide food for the animal community. Light levels in aphotic zone are too low to support photosynthesis. The seafloor is called the Benthic realm. Fishes and marine mammals swim in open water known as the Pelagic realm. A distinctive Biome called an Estuary is found where a freshwater stream or river merges with the ocean.
Photic zone is the surface layer of the ocean that receives sunlight, which means it permits photosynthesis by plants and phytoplankton. In aphotic zone , there is no light, therefore the phytoplankton and algae can not grow and undertake photosynthesis, the carbon dioxide is accumulated, there is less Oxygen and the pH is lower than in the photic zone.

Answer:
It is a hypothesis that explains the origin of evolutionary reversions.
Explanation:
A phylogenetic tree may indicate that genes required for forming anatomical structures such as wings are not completely lost and they are activated many times during the evolution.
The beauty of plants being the reason for faster blooming cannot be tested using the scientific method.
<h3>The scientific method</h3>
It is a rational order of steps through which scientific investigations are conducted.
Beauty is a relative term and can be generally subjective. What is beautiful to one person might not be beautiful to others.
If we say that the lilies bloomed first before the asters because they are more beautiful, it will be difficult to categorize beauty into a metric variable, and thus, cannot be scientifically tested.
