In 1838, a German botanist, M.I.Schleiden studied the plant cells and emphasized that "cells are organisms and entire animals and plants are aggregations of these organisms arranged according to definite laws. "In 1839, another German zoologist T. Schwann stated "we have seen that all organisms are composed of essentially like parts namely of cells." The deductions of the two microscopists (Schleiden and Schwann) formed the basis of what came to be known as the cell theory. The cell theory holds that all living matter, from the simplest of unicellular organisms to very complex higher plants and animals, is composed of cells and that each cell can act independently but functions as an integral part of the complete organism.
Answer:
Light-dependent and Light-independent reactions
Explanation:
Light-dependent reactions capture the energy of light and use it to make ATP and NADPH. The light-independent reactions use ATP and NADPH to capture and reduce carbon dioxide.
<span>I believe is answer is the temperature is too low. If the main fermentation products will be always ethanol in the yeasts chosen for alcoholic fermentation, since the yeasts are growing well on the maltose, the temperature may be too low which causes poor extraction of color and tannins in red wines and can also cause sluggish fermentations and production of high levels of ethyl acetate.</span>
Answer: In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be found in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.
Explanation:
Answer:
A. Water molecules are split.
Explanation:
The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.
These electron carriers are used in the light-independent reactions of photosynthesis.
During this process, the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis
