Transcription takes place in the nucleus of the cell.
Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
Answer: d. all of the above
Renewable resources are those which can be replenished or reproduced at a faster rate. But heavily decrease in the volume of these resources sometimes cannot be compensated.
a. Loss of animal species: Hunting and poaching of animal species has limited the population of endangered species to derive valuables like horns, skins from these animals for human use.
b. Land degradation: Landmass occupied by natural forests and other natural biomes are cleared for human use like agriculture, mining, urban development. These lands are loosing their natural potential and are treated as waste lands.
c. Lower availability of fresh water: Water from water bodies like lakes, rivers, groundwater, ponds are polluted by industrial, agricultural wastes making water unfit for human use. Groundwater are pumped out to maximum amount but the same level cannot be maintained by natural sources of water such as rain, agricultural field irrigation, river or any other means therefore, limiting the level of water in grounds.
I think so Flat worms are more complex in all these options.because they have better response system than other options.
