FreshDirect custom-packages groceries and meals using just-in-time manufacturing, a practice that reduces waste, [5] [6] and improves quality and freshness. [7] The company was an early proponent of the move towards food sustainability and rapidly grew in popularity by catering to an urban, socially-conscious consumer.
Photosynthesis ( / ˌfoʊtəˈsɪnθəsɪs / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.
The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
Infobox references. Polyethylene glycol ( PEG; / ˌpɒliˈɛθəlˌiːn ˈɡlaɪˌkɒl, - ˈɛθɪl -, - ˌkɔːl /) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide ( PEO) or polyoxyethylene ( POE ), depending on its molecular weight.
The origin of water on Earth is the subject of a body of research in the fields of planetary science, astronomy, and astrobiology. Earth is unique among the rocky planets in the Solar System in having oceans of liquid water on its surface. [2] Liquid water, which is necessary for all known forms of life, continues to exist on the surface of ...
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [citation needed] The aquatic vascular plant Myriophyllum spicatum produces ellagic, gallic and pyrogallic acids and (+)-catechin, allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa.

Fiber is a nutrient that comes from the food you eat and is an essential part of a healthy diet, according to the National Institutes of Health (NIH). The current recommendation for daily fiber ...
Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water ( green arrow ). An autotroph is an organism that can convert abiotic sources of energy into energy stored in organic compounds, which can be used by other organisms. Autotrophs produce complex organic ...
