Answer:
c. They may evolve into two separate species as a result of disruptive selection
Explanation:
Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.
With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.

The correct answer is C. It continues to eat the amount of food it does normally.
When rat's ventromedial nucleus is destroyed the rat will become more hyper physics and it continues to eat until it has doubled its normal weight.
Ventromedial nucleus of hypothalamus is termed as nucleus of hypothalamus.
It is a distinct morphological nucleus which involved in terminating hunger, fear, sexual activity and thermoregulation.
Ventromedial nucleus of hypothalamus is divided into subdivisions. For example, dorsomedial, ventrolateral, central and anterior. VMN is most commonly associated with satiety. In rats ventromedial nucleus is caused by over-eating and obesity.
Members of phylum Porifera are commonly known as spongs. They are generally marine and mostly asymmetrical animals. These are primitive multicellular animals and have cellular level of organization (lacks tissues). These Organisms (belonging to phylum Porifera) lacks most of the structures that are present in multicellular organisms like digestive system, respiratory system, Brain etc
Body of Spongs are made up of spicules or spongin fibers and these organism contain a water canal system which helps them in digestion, reproduction and catching their food in marine habitat.
