Answer:
DDWw x Ddww
DdWw x DDww
DDWw x DDww
Explanation:
D for tallness
d for dwarfness
W for violet
w for white
For Parental Plants that has
tall, violet x tall, white
The representation will be
DDWW × DDww (We the apply the mendelian crossing)
This will yield offsprings with the following trait
DDDD × DwDw
DDDD × DwDw
DWDW x WwWw
DdWw x ddww
Ddww x ddWw
DdWw x DdWw
DDWw x ddww
From the above Offsprings
1/2 tall, white and 1/2 tall, violets offspring are
DDWw x Ddww
DdWw x DDww
DDWw x DDww
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
Warmer oceans would mean less dissolved CO2 as well as other gases such as oxygen in the global ocean. Lower CO2 would result in a decrease in photosynthesis of autotrophs living in the oceans.
