Answer:
Carotenoids and Anthocyanins
Explanation:
During the winter the sunlight is limited for a long period of time. Plants will lose their leaves but first they will turn bright colors. The reason for this is as follows:
Plants' leaves appear green because of the presence of chlorophyll. During the fall the plants attempt to save energy. So, before they drop the leaves they first break down the chlorophyll into smaller molecules so they do not have to make the molecules from scratch all over again when spring comes. What is left behind is the Carotenoids that appear yellow and orange and Anthocyanins that appear purple.
All of the chemical reactions in an organism required to sustain life so C
Number of grams of salt in one kilogram of water is the best description of the salinity of ocean water.
Salinity is a measure of dissolved salts in water bodies such as oceans, rivers, seas etc. Salinity is calculated as the amount of salt (in grams) dissolved in one kilogram (1,000 grams) of seawater. Sodium chloride are the main salts with other elements such as magnesium, calcium and potassium that can be found in sea water.
