The hemoglobin holoenzyme (active enzyme) is a complex of an iron ion and 4 subunits- 2 hemoglobin alpha and two hemoglobin beta. People with sickle cell disease have mutated beta hemoglobins. The mutation is a single nucleotide exchange, that changes the 6th amino acid of  protein primary struture - a Glutamic acid into Valine. This one alteration changes the tree dimentional structure of hemoglobin beta so, that it forms lond fibres that disrupt the normal circular form of the red blood cells.

Summarize how the climate of the Miocene epoch impacted the evolution of hominins
andrezito [222]

Answer with Explanation:

The Miocene epoch was deeply characterized by<em> seasonal conditions</em>, such as having more colder winters in the northern areas.

In the <em>late Miocene</em>,<u> open vegetation system expanded. </u>These included<em> grasslands, woodlands and shrublands.</em> As a result, more primates inhabited the area. Several habitats became diverse from each other, thus allowing the species to adapt, including their locomotion. For example, the species who used to live on trees, turn towards living on land (terrestrial life). Certain animals also came about such as <em>pigs, giraffes, monkeys, etc.</em> Scavenging hominins also scattered. When it comes to hominins, a major type of locomotion evolved called "bipedalism." <u>This allowed the hominins to walk using the lower limbs (two feet).</u>
