Ground water usually contains carbonic acid
The seeds she planted in the mud grew quicker because the mud is holding nutrition for the corn. The soil is a good guess to make, but the mud is more dense and moist. The water wouldn't have had more nutrients than the mud, just because the mud holds breakdown matter and other things from other plants.
True
Explanation:
Concerns over a global dependence on fossil fuels include environmental, economic and social consequences. The effect of reliance on fossil fuels cuts across on almost all aspect of life.
- Environmental concerns include pollution, acid rain, global warming e.t.c
- Economic consequences involves monopoly of the energy market, scarcity, inflation, corruption e.t.c
- Social consequences include reduced standard of living, poverty, e.t.c
Fossil fuel is a non-renewable source of energy.

C is correct
A is incorrect because the far right lane of the road is NEVER a U-turn lane unless you can drive on the sidewalk legally (you can't)
B is incorrect it is not always the lane next to the center lane
Answer:
C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.
Explanation:
The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.
The heterozygous plant Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).
- Dr: parental
- dR: parental
- DR: recombinant
- dr: recombinant
To calculate the frequency of each type of gamete, we must use the formula:
Distance (map units) / 100 = frequency of recombination.
18 mu / 100 = 0.18.
The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.
The frequency of parental gametes will be:
1 - frequency of recombinant gametes
1 - 0.18 = 0.82
But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.
