Answer:
A. A 300 Å fiber with 6 nucleosomes per turn is visible using electron microscopy.
C. Using electron microscopy, nucleosomes appear like beads with a diameter of 100 Å.
E. Loops of chromatin are visible using electron microscopy.
Explanation:
The nucleosomes are the key subunits of the chromatin, and they consist of two turns of DNA wrapped around a set of two copies each of the H2A, H2B, H3, and H4 histone proteins (i.e. an octamer of histones), which are connected by linear DNA and H1 histones. A zig-zag array of the nucleosomes form a 100 Angstrom (10-nm) nucleosome fiber. Subsequently, multiple histones are packaged into a 30-nanometer (300 Angstrom) fiber named solenoid. The chromatin loops are finally condensed into higher-order structures, which form chromosome sections (300 nm) and chromosome arms (700 nm), respectively.
Answer:
It is absorbed by the clouds.
It is reflected by clouds
It is reflected by glacial ice.
Explanation:
Solar radiation is the energy that is emitted by the sun which is as a result of nuclear reactions that form electromagnetic energy. It experience different things when it comes in contact with different surfaces. When it comes in contact with the Earth, it is absorbed by it, the cloud reflected part of it and it is also reflect by glacial ice which serve as mirror. Solar radiation can be converted to heat and useful form of energy.
The answer should be "Island finches resembled mainland finches, but were not the same species."
