Answer:

Photons

Explanation:

The retina is a thin layer (membrane) in the eye that receives light through photoreceptor cells that convert this light into chemical and nervous signals transported to the brain's visual center.

The photoreceptors in the retina are known as rods and cones. Rods detect motion and sare responsible for black and white vision, they are present in the macula. Cones on the other and, are responsible for central and color vision. These photoreceptors absorb photons that trigger the membrane's potential of the cells.

The classes of chordata which are warm-blooded are birds and mammals.

Explanation:

Warm-blooded animals are those which can maintain their body temperature at a constant.

These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.

The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.

Warm blooded animals cool themselves with the help of sweat glands.

The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.

These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.

Whale living in water is the fish which is also warm blooded because it is a mammal.

Reptile [31]

Answer:

The correct answer will be option-C.

Explanation:

The evolution of human species in which one species transformed into another species evolves by a mechanism known as anagenesis.

Anagenesis is the mechanism of evolution which transform one species into a different species within a lineage. This process is slow and takes time to form species, therefore, is also known as gradualism or phyletic transformation.

The Homo sapiens evolved from Homo erectus where Homo sapiens overwrites the ancestral species and caused the species to become extinct.

Thus, Option-C is the correct answer.
