Answer:
Characteristics
Explanation:
not genetic diversity that would invlove other organisms, not dna because DNA is not being replictaed, and not A because come on
Forms solid that are relatively insoluble and nontoxic
Uric acid is product of the metabolic breakdown of the purine nucleotides. It is considered as a normal component of urine. In birds and reptiles the evolved the ability to convert toxic ammonia into uric acid or guanine rather than urea. These organisms are called as uricothelic organism because they have the ability to convert toxic ammnonia to uric acid instead of urea. Uric acid is less toxic than ammonia.
Answer:
respirations can be consciously controlled.
Animal Circulatory Systems An efficient circulatory system has: a fluid, e.g., blood, to carry the materials to be transported; a system of vessels to distribute the blood; a pump to push the blood through the system; exchange organs to carry out exchanges between the blood and external environment, e.g., lungs and intestine to add materials to the blood; lungs and kidneys to remove materials from the blood. The most crucial demand on the circulatory system is the transport of oxygen and carbon dioxide to and from a gas exchange organ: lungs or gills and the tissues. All exchanges between blood and cells occur in the capillaries. The force of the pump that pushes blood through the arteries is dissipated as the blood flows through capillaries.
Answer:
Climate changes arise when the Earth has an energy imbalance which causes the Earth to gain or to lose heat.
Looking at the past climatic changes helps us to understand how the climate of the Earth reacts to external forcings. The study of paleoclimates have enabled us to understand that the climate of the Earth can shift between different climate states in just a few number of years or a few decades. The studies of the past climate changes also enables us to understand how humans might have affected the climate in the past and in the present day.
As the data obtained from these observations is not clearly direct, we cannot consider it to be highly authentic. As we know, many a times, scientists form theories in a way that benefit their own perspectives.
