Answer:
Explanation:
electrons i believe. That is why an atom has a neutral charge- electrons and protons cancel each other out
Answer:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest
Explanation:
Among the given choices:
A) Of the stars listed, Proxima Centauri and Barnard's Star appear red because they burn the hottest.
This is not the correct answer because temperature of Barnard's star is 5000° F which is lowest in the data.
C) Small dwarf stars, like Proxima Centauri and Barnard's Star, do not burn as hot as medium dwarfs.
Proxima centauri being a small dwarf has a higher temperature than sun which is a medium dwarf.This shows that small dwarfs can burn hotter than medium dwarfs. So this option is not suitable.
D) Proxima Centauri and Barnard's Star are the closest because they are classified as "small dwarfs."
This is not correct choice because the data clearly states they are at greater distance.
So ,the correct choice is:
B) As seen from Earth, the Sun is the brightest star on the chart, and Barnard's Star is the dimmest.
Because: Sun is closest to the Earth and thus will appear the brightest as maximum light from it Reaches the Earth. Barnard's star is Farthest so less light reaches the Earth from it and it appears the dimmest.
Carbon dioxide fixation in plants occurs at the STROMA.
Carbon dioxide fixation is the first step in the Calvin cycle and it occur in all plants. Carbon fixation is the process by which inorganic carbon is converted to organic compounds by the plants. The process of carbon fixation converts carbon dioxide and ribulose biphosphate into 3 phosphoglycerate.
Carbon is a chemical element with symbol C and atomic number 6. On the periodic table, it is the first of six elements in column, which have in common the composition of their outer electron shell. It is nonmetallic and tetravalent.
