Cells -> Tissues -> Organs -> Organs systems -> Organisms
Answer:
This way, for 20^2.55 = 2109 amino acids are require to have 2*1056 number different sequences.
Explanation:
Protein should contain 2*1056 of different sequence so
2*1056 = 20^x
Log (2*1056) = log 20^x
3.3246 = (x ) * 1.3010
X= 2.555
Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity.
