Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.
The correct answer is water
<u>Answer</u>:
The high sea surface salinity can be observed in the Pacific Ocean, the Indian Ocean, the Arabic ocean and the Mediterranean sea.
<u>Explanation</u>:
Due to rainfall and evaporation of water from sea the density varies with varying salts and minerals concentration that aggregate at the surface. The salinity in the seawater varies according to the amount of evaporation from a particular area.
Low salinity water is found in polar and subpolar regions that are near to the equator. Regions of high salinity are observed in the seawater which is centered around 30 degrees north and 30 degrees south to the equator due to the excess evaporation in these areas.
