The rocky upper layer of the solid earth is called the "lithosphere". This rocky part includes the brittle upper portion of the mantle and also of the crust. It is bounded by the atmosphere above and of the asthenosphere which is another part of the upper portion of the mantle.
Answer:
Answer no 1
Location that experience seasonal sea water freezing have increased salinity in the surrounding seawater during that time.
When water freezes, it form sea ice which expel out salt into surrounding water and increase the salinity of surrounding seawater.
Answer no 2
Location that experience seasonal ice melting have decreased salinity in the surrounding sea water during that time.
Answer no 3
Sample A which has high salinity content and taken from Atlantic ocean represent just east of the Bahamas
Answer no 4
Sample B which has moderate to low salinity is represent off the West coast of Africa near the equator.
Answer no 5
Sample C which has high salinity content is taken from Red Sea.
Answer no 6
Sample D which moderate to low salinity content, is taken from Baltic Sea.
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.
It tells you that a large amount of their brain processing is oriented towards visual cues/stimuli. Because they can view a much larger degree of range laterally than can humans and need to be able to.
