Higher levels of hemoglobin means that an organism is able to survive off less oxygen. Hemoglobin moves oxygen around the body which allows the organism to survive with less of it, especially if the organism has more hemoglobin.

The correct answer is option b. higher levels of hemoglobin.

The partial pressure of the oxygen decrease as the height from the sea level is increased. Due to the decrease in the partial pressure, the amount of the oxygen delivered by the hemoglobin to cell decrease. So, in order to cope up the condition, the amount of the hemoglobin in the blood is increased. the increased amount of the hemoglobin delivers more oxygen than the normal amount of hemoglobin can do, so, it help in survival at low oxygen levels.

Briefly outline the progressive evolution of the respiratory and circulatory systems in vertebrates
nikitadnepr [17]

Answer:

The circulatory system has evolved over time from simple diffusion through cells, in the early evolution of animals, to a complex network of blood vessels that reach all parts of the human body. Made of specialized and unique cardiac muscle, it pumps blood throughout the body and to the heart itself.

Claps shut at birth. Evolutionary changes in the vertebrate heart are tied to change from single to double-circuit heart, with increased separation of oxygenated and deoxygenated blood, allowing more efficient respiration and circulation to fuel high activity and increased oxygen demands associated with endothermy.

bisphosphoglyceric acid (bpg) is a byproduct of glycolysis released into the bloodstream when an animal's supply of oxygen is lo
valentina_108 [34]

When an animal's oxygen supply is limited, bisphospoglyceric acid increases the oxygen level by acclamitization.

Acclimatization is the term used to describe the advantageous physiological changes brought on by frequent exposure to a hot climate. Increased sweating effectiveness is one of these physiological modifications. It is converted into a molecule identical to that of 2,3-bisphosphoglyceric acid (2,3BPG). A mechanism called 2,3BPG is employed to control the effective emission of oxygen from haemoglobin. As one of the processes of acclimatization, 1,3-BPG levels will rise in a patient's blood when concentration is low. Low oxygen levels increase 1,3BPG levels, which in turn increase 2,3BPG levels and change how well oxygen separates from hemoglobin.

In intramembranous ossification, newly formed bone that is immature and not well organized is called ______.
OleMash [197]

Answer:

Woven bone.

Explanation:

In intramembranous ossification, newly formed bone that is immature and not well organized is called woven bone. Osteoblasts are the type of cells that is responsible for the formation of new bone. These osteoblasts also come from the bone marrow and are related to structural cells. They have only one nucleus. The process of bone formation is called osteogenesis whereas there are three stages of bone development i.e. proliferation, maturation of matrix, and mineralization.
