Answer:
Because it prevents venous blood from mixing with arterial blood (which is rich in oxygen), in this way the circulation is more efficient.
Explanation:
In land vertebrates, the blood circulation is structured in two independent circuits: the pulmonary circulation, where oxygenation of the blood occurs and the elimination of the carbonic anhydride that it contains, returning back to the heart through its left atrium; and the systemic or major circulation, impelled from the left ventricle, transports the oxygenated blood and the nutrients that it assimilates as it passes through the digestive system, to the tissues of the animal, where it is charged again with anhydride carbonic and other waste substances, returning back to the heart, where it enters through the right atrium. These systems are independent and prevents venous blood (which is poor in oxygen) from mixing with arterial blood. These systems are independent and prevents venous blood (which is poor in oxygen) from mixing with arterial blood.
Answer:
Endothermic
Explanation:
Amphibians are ectothermic organisms. Ectothermic animals are coldblooded animals. From the options above, the correct answer is endothermic because amphibians are not hot blooded and are never endothermic.
Think it’s answer D but it maybe B
hope this helps!!
sorry if it’s wrong
A because Only plant cells have chloroplasts
The answer is letter A. According to the principal of dominance, if a recessive gene for tallness is paired with another recessive gene for tallness, the organism will be tall.<span>
By principle, any of two recessive genes will form the characteristic it holds. Dominant genes however only require one to for a trait.
