D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
Answer:
Sharp-spined cactus
Explanation:
Given, that N allele is required for the production of spine and S allele will produce sharp sines.
True breeding sharp spined cactus: NNSS
spineless cactus: nn__ ( we can't fix the allele for second gene since it has not been mentioned as true breeding )
Their progeny: NNSS X nn__ = NnS_
So the progeny is going to be sharp spined because both the dominant alleles N and S are present.

Answer:
Water is slower to heat than most materials.
Explanation:
There is a physical property called "specific heat". This property determines the amount of temperature necessary to change 1ºC in the temperature of the materials. The higher the specific heat of the material, the slower it will heat up.
The water has an extremely high specific heat, which means that it will slowly heat up to an extremely high temperature. The specific heat of the water is greater than most materials and this explains why high variations and external temperature changes almost do not cause changes in the water of the picisnas, for example.
