The correct answer is option B. Higher levels of haemoglobin
A higher level of the haemoglobin allows the organism to survive in low oxygen condition. The low oxygen level decreases the amount of oxygen delivered to the cells, to cope up this condition, there is an increase in the haemoglobin content. The increased haemoglobin concentration allows the delivery of the sufficient amount of oxygen, as the number of haemoglobin increase, the capacity of oxygen carried to the cell is increased.
Answer:
Angiography
Explanation:
Doctors often use angiography that images the structure of blood vessels and the flow of blood through these vessels.
- Angiography uses x-rays to take images of blood vessels and detect the flow of blood through these vessels.
- Useful in showing blocked or narrowed blood vessel for the diagnosis of any coronary disease.

Answer:
<h2>It Has 4 Seasons</h2>
Explanation:
It has four distinct seasons: winter, spring, summer and fall. Winters are cold and summers are warm. Temperate deciduous forests get between 30 and 60 inches of precipitation a year. Precipitation in this biome happens year round.
Structure is a better indicator of shared ancestry than function. When species share the same structure despite not needing similar structures functionally, it shows that there was almost definitely a common ancestor.
Answer:
Feedback loop will fail in an ecosystem if the factors regulating the feedback mechanisms fail to function.
Explanation:
Feedback loop is the phenomena in which output is circled back in a way that it is used as input again i.e the reaction is circled back. Its a continuous process.
There are two types of feedback loops, positive and negative, one functions to reinforce and other functions to balance. Positive feedback loops enhance the outputs while negative lower the output and keeps the balance. the variables that are involved in all these processes effect each others so, by eliminating such variables or factors will cause failure of feedback loops.
