1 is The greater the energy, the larger the frequency and the shorter (smaller) thewavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic than long wavelengths.

2 is he Sun & its Energy. The sun's energy is the primary source of energy for all surface phenomena and life on Earth.
Combined 
with the material of the Earth (including the molecules held close by the Earth's gravitational force called the atmosphere), this energy provides for the immense diversity of life formsthat are found ...  

3 is The light that we<span> see is a type of </span>electromagnetic radiation<span>. However it is only a very small part of the entire </span>electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.Electromagnetic radiation<span> is different from sound in that it </span>can<span> travel in space and </span>does<span> not need a medium like air or water </span>to<span> travel

How is the work of the digestive and circulatory systems related to the respiratory system?
Lyrx [107]
The circulatory system brings nourishment to all cells of the body. The circulatory system exchanges critical gases with the respiratory system; unneeded carbon dioxide is exchanged for much needed oxygen. The respiratory system provides oxygen so the body can "burn" (oxidize) the food that is brought into the body through the digestive system<span>.</span>

Sickle-cell disease is caused by a single base pair substitution in the gene for the beta globin subunit of hemoglobin. This bas
Nadya [2.5K]

Explanation:

Sickle cell anemia is a disease that is caused by the sickle shape of the oxygen carrier molecule called hemoglobin in the blood. The hemoglobin since is a protein, therefore, is composed of the amino acids and it is the 3 D arrangement of these amino acids which provides proteins its function.

The amino acids are coded by the DNA present in the molecule therefore the shape is the result of the DNA.  The mutation in the DNA causes the substitution of the glutamic acid to valine at 6th position.

The glutamic acid contains -COOH group in its R side chain which becomes C00- as a result of which the amino acid is negative and acidic in nature. This negative charge allows the formation of bonds with positive change which stabilizes the structure of the protein.

Valine is a neutral and non-polar amino acid therefore will not form any bond with the proteins and thus a stable structure is not formed.  This difference in the side chain in the amino acids is the region the hemoglobin structure is changed.
