Answer: C. placentals.
Explanation:
The placentals are the mammals which give birth to a fully developed live young individual. These animals are characterized by the presence of placenta which creates a boundary around the fetus. The transfer of food takes place through the tissues of the placenta. Also the wastes are excreted out through placenta.The placental mammals keep their fetus inside the placenta for a complete period of gestation until the complete physical form of the fetus get developed.
Answer:
Option C, Each subpopulation is linked to all other subpopulations by dispersal.
Explanation:
Each sub-population with in a metapopulation is not only connected by the dispersal distance travelled by an organism but also by the distance between the patches on which two sub population live. There are several other factors that limitise the concept of connection of subpopulation by dispersal factor and these vulnerable factors are – properties of terrain between the patches and its adverse affect on the dispersal behaviour of dispersing agent/species.
Hence, option C is correct.
The Doppler effect can be experienced when an ambulance is approaching you. Due to the ambulance moving closer to you, the gap between the wavelengths is decreased, leading to you hearing the siren at a much higher frequency than when the ambulance has passed you! Hope this helps!

If they choose to go solar, their house would have to have plenty on sunlight through the day, and they should not live somewhere that gets snow or is cloudy the whole day because it would block the amount of sun the house could get. They would have to plan ahead to figure out if they could use solar or not based on their home and property.
