Answer: Hemoglobin is an iron containing protein composed of four polypeptide chain and made from 574 amino acids. It play a key role in oxygen transport from lungs to all parts of the body.
Mutation in hemoglobin: If mutation occurs in hemoglobin then glutamine amino acid is replaced by valine amino acid which lead to abnormal hemoglobin structure which is sickle shaped and can not pass through blood vessels resuting into deficiency of oxygen in the body and the disease called is known as sickle cell anaemia.
Answer:
The wind moves from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses
Explanation:
Relationship between wind speed and direction to air temperature:
wind flows from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses.
A. The land air will heat up more during the day. This is because the land has a lower specific heat capacity than water, hence increases a lot more rapidly in temperature than the sea when the sun comes up.
B. The air packet over the land will cool down more rapidly at night due to the lower specific heat capacity of land when compared to the sea.
Answer: She does not need to complete another step.
Explanation:
Mendel's 2nd law of inheritance is also known as law of independent assortment of genes.
It states that each character behaves as a SEPARATE unit and is inherited INDEPENDENTLY of any other character.
Therefore, the cross BETWEEN the blue-flowered plant with a red-flowered plant NEED NO OTHER step to explain inheritance pattern.
