The other most studied microalga is Chlorella, which also has been objective of genetic manipulation. In particular, as this microalga is capable of hexose uptake from the culture medium, some mutants have been created with the aim of evidencing how the carbohydrates accumulation in the biomass may...

Therefore oxygen has8 electrons. You will find that the atomic weight of oxygen is about 16. How many protons neutrons and electrons does oxygen-16 contain? Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natura...
Oxygen-18 (18O) has 10 neutrons and 8 protons in its nucleus. Its NA is 0.2%. Allotropes of Oxygen An allotrope of an element pertains to any of the multiple substances formed by only one type of element. Examples of allotropes of oxygen are atomic oxygen, dioxygen, ozone, and tetra...
How many neutrons are there in an atom of lead whose mass number is 208? How many neutrons are in a typical oxygen atom? What is the atomic mass of oxygen 16? What is the atomic mass of oxygen? What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons?
Mayow observed that: substances do not burn in air from which oxygen is absent; oxygen is present in the acid part of potassium nitrate [i.e., in the nitrate – he was right!]; animals absorb oxygen into their blood when they breathe; air breathed out by animals has less oxygen in ...
The mechanism by which the Mn-containing oxygen evolving complex (OEC) produces oxygen from water has been of great interest for over 40 years. This review focuses on how X-ray spectroscopy has provided important information about the structure of this Mn complex and its intermediates, or S-sta...
How many cell membranes does oxygenshave to pass through?Question:How many cell membranes does oxygenshave to pass through?Oxygen:Oxygen is a chemical element which has eight protons in its nucleus. It can attain the stable electron configuration of the noble gas neon by acquiring two electrons ...
Proton release has been reported in the S0 to S1 state transitions, suggesting structural modification of the Mn-cluster [38], [39]. Some possible situations based on the results in the present study are: (1) the protons released during the S0–S1 state transition are not located in the ...
