Answer:The answer is C: The nucleus divides in the stage before the cytoplasm divides, I just took a test and it had this question and this was the answer!
Explanation:
They range from the dry desert conditions of northern Chile to the heavy rains along the windswept southwestern coast of the continent
Id say they stay with them and nurture them
Answer:
The binding of carbon monoxide (CO) with hemoglobin leads to an R state even in conditions that should produce the release of oxygen. In consequence, CO-hemoglobin binding shifts the oxygen dissociation curve to the left.
Explanation:
Hemoglobin is a globular protein containing four heme groups that can bind to one oxygen each. This protein (hemoglobin) has two conformational states: the T-state, also known as deoxyhemoglobin (a tense state, where lacks O species), and the R-state, also known as oxyhemoglobin (a relaxed, fully oxygenated state). When carbon monoxide binds to hemoglobin, the protein can not release oxygen, shifting the oxygen dissociation curve -which expresses the percentage of oxygen saturation against the partial pressure of oxygen- to the left. Therefore, under CO-hemoglobin binding, the oxygen level in the tissues is reduced.
