B. Pine trees, this is the answer that was right after I took the test XD
The genotype of the plant is <span>WwXxYyZz.
The plant has a 50% chance of passing each of the alleles of a gene, the dominant or the recessive.
So, for producing the haploid genotype of a gamete </span><span>Wxyz the chance is
0,5 (W)* 0,5 (x)* 0,5 (y) * 0,5( z)= 0,0625
</span><span>

It is (D) Carbon dioxide.
in lactic acid=C6H12O6 to produce 2C3H6O3+Energy.
in alcoholic fermentation=C6H12O6 to produce 2C2H5OH+2CO2.
therefore all of them produce (D) Carbon dioxide.
The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
The answer is: [A]: "A process that cleans pollution from a local pond" .
