Question

Chromatophores in frog’s skin are controlled by
A. Hormones
B. Environment
C. Nervous activity
D. Nervous and hormonal activities

Answer 1

Hint: Chromatophores are pigment-containing and light-reflecting cells, or gatherings of cells, found in a wide scope of creatures including creatures of land and water, fish, reptiles, shellfish, and cephalopods. Warm-blooded animals and winged creatures, conversely, have a class of cells called melanocytes for tinge.

Complete answer:
Chromatophores are generally answerable for producing skin and eye tone in ectothermic creatures and are produced in the neural peak during the undeveloped turn of events.
Three sorts of pigmented cells, called chromatophores, cooperate to make a frog green. The chromatophores stack on the head of one another. Melanophores make up the base layer. They contain melanin, a color that seems dim earthy colored or dark. Melanin additionally colors human skin. Creatures of land and water profit by the tones that they show in various manners, going from keeping up internal heat level to dodging hunters.
Melanophores are a kind of chromophore. These melanophores are available on the skin of a frog with melanin scattered all through the parts of the cells. This impact is created by a hormone called MSH, i.e., melanocyte-stimulating hormone (MSH). It depicts a group of hormones created by the pituitary organ, nerve center, and skin cells. It is significant for shielding the skin from UV beams, improvement of pigmentation, and control of hunger.

Hence, the correct answer is option (A).

Additional information:
A frog's focal sensory system is comprised of two organs, a cerebrum, and a spinal line. Its mind is contained in a hard structure known as a cerebrum box or a skull that shields the mind from outside powers. The olfactory controls the frog's feeling of smell.
All through their lifecycles, frogs have a significant spot in the natural way of life as the two hunters and prey. As fledglings, they eat green growth, managing sprouts, and decreasing the odds of algal defilement.

Note: Chromatophores are sporadically molded color containing cells. Melanophores are a kind of chromophores. These melanophores are available on the skin of a frog with melanin scattered all through the parts of the cells. This impact is created by a hormone called MSH, i.e., melanocyte-stimulating hormone (MSH). At the point when the shade retreats to the focal point of the cells, the skin helps.
