Answer:
. really big surface area.
.thin walls
.a lot of tiny blood vessels
.the transfer of oxygen from the outside air to the blood flowing through the lungs
Explanation:
Endothermic feature distinguishes birds from the rest of the reptiles. So, the correct option is (a).
A crucial adaptation that allowed reptiles to exist on land was the growth of their scaly skin, that stopped water loss from the skin. Ectotherms are animals whose primary source of body heat is the environment. Reptiles fall under this category. They control their body temperature using behavioural strategies including self-heating by basking or self-cooling by seeking cover in burrows or shade.
Birds are endothermic, in contrast to reptiles, which means they produce their own body heat through metabolic processes. The feathers on birds, which are repurposed reptilian scales, are what set them apart from other animals. The first birds' feathers allowed them to glide and eventually take to the air in a flapping motion. They also served to insulate the bird's body and aid in the preservation of body heat.

<span>In some individuals suffer stem cell damage when exposed to chemical agents but others do not, the main reason for that is that individuals are affected by superior detoxification.
Detoxification is the physiological or medicinal removal of toxic substances from a living organism, including the human body, which is mainly carried out by the liver. Additionally, it can refer to the period of withdrawal during which an organism returns to homeostasis after long-term use of an addictive substance.</span>
